Description

  The present invention relates to an apparatus, system, and method for counting the number of lightning strikes as a basis for calculating a compensation amount when compensating for a customer's loss when an instantaneous voltage drop occurs in the customer due to a lightning strike to an overhead power transmission line. About.

When a lightning strike occurs on an overhead power transmission line, an instantaneous voltage drop occurs in the power supplied to the customer, which adversely affects electronic products. For example, Non-Patent Document 1 exemplifies the following as an influence of an instantaneous voltage drop on an electronic product.
(1) In a variable speed motor for power electronics application, if a voltage drop of about 15% or more continues for about 0.01 seconds or more, an effect occurs.
(2) In an electromagnetic switch, when a voltage drop of about 50% or more continues for about 0.01 seconds or more, an influence occurs.
(3) In a high-pressure discharge lamp, if a voltage drop of about 15% or more continues for about 0.06 seconds or more, an influence occurs.
(4) In a personal computer, if a voltage drop of about 40% or more continues for about 0.06 seconds or more, an effect is produced.
(5) With an undervoltage relay, an effect occurs when a voltage drop of about 20% or more continues for about 1 second or more.

As described above, even an instantaneous voltage drop affects the electronic product and causes an economic loss to the customer. In relation to such a problem, for example, Patent Literature 1 discloses a lightning strike information providing system for quantitatively calculating and providing an influence of a lightning strike on a customer facility.
"Instantaneous voltage drop countermeasures", Electric Joint Research, Vol.46, No.3 JP 2003-47173 A

  In order to prevent the customer's economic loss due to the effects of lightning, as exemplified in Non-Patent Document 1, measures such as installing a power failure compensation device at the customer or taking lightning countermeasures at an electric power company are effective. It is. However, since these measures are costly to implement, it is not realistic to try to prevent all economic losses due to lightning strikes by these measures alone.

  Therefore, in order to compensate for the customer's economic loss due to lightning strikes, it is conceivable to provide customers with financial compensation, such as discounting electricity charges according to the number of lightning strikes or providing insurance money. For example, in Japanese Patent Application No. 2004-42879, the applicant of the present application uses an instantaneous voltage that can be used to provide financial compensation to a customer when a customer's instantaneous voltage drop occurs due to a lightning accident on an overhead power transmission line. We are proposing a decline-based electricity bill calculation system.

  By the way, lightning strikes frequently occur a plurality of times. For example, there is no significant difference in the influence of a customer when it occurs once in a short time such as 10 seconds and when it occurs several times. Further, the degree of influence that a customer receives when lightning strikes continuously varies depending on the customer's facility environment. That is, if it takes 10 seconds for an electrical equipment of a customer to recover from the effect of the instantaneous voltage drop due to lightning, for example, no matter how many lightning strikes occur during that 10 seconds, the loss experienced by the customer will not change much. When lightning strikes occur at intervals exceeding 10 seconds, the loss increases with the number of times. Also, if another customer's electrical equipment takes 1 hour to recover from the effect of the instantaneous voltage drop, no matter how many lightning strikes occur during the hour, the loss will not change much, and lightning will occur at intervals exceeding 1 hour. When this occurs, the loss increases with the number of times. Therefore, when providing financial compensation to customers according to the number of lightning strikes, count the number of lightning strikes using a method that is suitable for the customer's facility environment, and the number of lightning strikes corresponding to the magnitude of the impact (economic loss) on the customer. The compensation amount should be determined based on

  The present invention has been made in view of the above points, and in making up for a customer's economic loss due to a lightning strike, a lightning strike count device for counting the number of lightning strikes corresponding to the magnitude of the economic loss experienced by the customer. It is an object to provide a system and method.

When a lightning strike occurs, a lightning strike data acquisition unit that obtains lightning strike data including at least the date and time of occurrence and the location,

It is characterized by providing.

  In the present invention, the lightning strike data includes a lightning current value, and the lightning count condition includes a lightning reference current value that serves as a reference for counting the number of lightning strikes. The number of lightning strikes may be counted only when the lightning strike current value included in the lightning strike data is greater than or equal to the reference current value contained in the lightning strike count condition.

In addition, the count condition acquisition unit is based on an observation condition acquisition unit that acquires an observation condition including the reference period and a customer location point for each transaction ID of each transaction, and the acquired customer location point. And an observation target area acquisition unit that acquires the observation target area for the corresponding transaction ID by inquiring the power company system about the area affected by the lightning strike on the power transmission path to the customer. Good.

  The lightning strike count device of the present invention can be used to count the number of lightning strikes in financial derivative transactions using the number of lightning strikes as an index.

In addition, the present invention is a system for counting the number of lightning strikes, which is the basis for calculating the amount of compensation when compensating for the economic loss of the customer due to lightning strikes,
A lightning strike observation device that detects at least the occurrence date and position when a lightning strike occurs,

It is characterized by providing.

  According to the present invention, it is possible to count the number of lightning strikes corresponding to the magnitude of the economic loss experienced by the customer when compensating for the economic loss of the customer due to the lightning strike.

  Hereinafter, an embodiment of the present invention will be described by way of an example of a system used for carrying out an option transaction using the number of lightning strikes as an index. Here, option transactions using the number of lightning strikes as an index (hereinafter referred to as lightning option transactions), for example, a financial institution such as an insurance company makes a contract with a customer of an electric power company, and the customer pays an option fee (ie, an insurance fee). The financial institution compensates the economic loss caused to the customer by the lightning strike by paying the customer an amount corresponding to the number of lightning strikes. In other words, as described in the above prior art, when a lightning strike occurs on an overhead transmission line of an electric power company, an instantaneous voltage drop occurs in a customer who receives power supply, which causes the production machine in the factory to stop. Economic losses occur due to the effects of lighting off or computer shutdown. This loss is compensated by paying the customer from the insurance company an amount corresponding to the number of lightning strikes.

  Note that even if a lightning strike occurs, the instantaneous voltage drop does not always occur, and the instantaneous voltage drop may occur due to a cause other than the lightning strike. Therefore, in order to compensate for the customer's loss due to the instantaneous voltage drop, strictly speaking, the number of occurrences of the instantaneous voltage drop should be used as an index instead of the number of lightning strikes. However, since the occurrence of the instantaneous voltage drop occurs under the customer and can be recognized only by the customer, it is difficult to objectively determine the occurrence of the instantaneous voltage drop. In addition, it is considered that there is a certain correlation between the number of lightning strikes and the number of instantaneous voltage drops. For example, when examining the relationship between the number of lightning strikes per year and the number of occurrences of instantaneous voltage drop in the entire Chugoku region from 1989 to 2003, as shown in FIG. 1, the number of occurrences of instantaneous voltage drop increases as the number of lightning strikes increases. It can be seen that it increases almost linearly. Therefore, as described above, in the present embodiment, lightning strike option trading is performed using the number of lightning strikes that can be objectively observed as an index.

  In addition, lightning strikes affect customers when lightning strikes a transmission path related to power transmission to the customer, and even if lightning strikes occur in an area unrelated to power transmission to the customer, the customer is affected. There is no. Therefore, in lightning strike transactions, it is necessary to count only the number of lightning strikes that occurred in an area that could affect customers and use it as an index. Therefore, in the present embodiment, the area corresponding to the power transmission path to the customer is specified using the information on the power transmission path owned by the power company, and only the number of lightning strikes that occurred in the area is counted. Hereinafter, an area that is subject to the number of lightning strikes is referred to as an observation target area. An economic loss due to a lightning strike may also occur when there is nothing to do with an instantaneous voltage drop due to a lightning strike to a transmission line, such as a golf course. In such a case, it is not necessary to use information on the power transmission path of the electric power company. For example, an area including a golf course may be set as an observation target area. As described above, the present invention is not affected by the instantaneous voltage drop caused by the lightning strike, but can be applied to the case where the loss is compensated in an industry such as a golf course where a lightning strike causes some economic loss. It is.

  In addition, as mentioned above, lightning strikes tend to occur multiple times in succession, and it takes a certain amount of time to recover from the effects of the first lightning strike. The impact of lightning strikes that occurred in a short period of time after the impact on can be ignored. Since the time required for returning from the influence of lightning strikes differs depending on the customer's facility environment, it should be set according to the customer how much lightning strikes occur within a certain period. Therefore, in the present embodiment, when lightning strikes continuously within a period set in accordance with the customer (hereinafter referred to as a reference period), only the first lightning is counted, and the subsequent lightning strikes are the number of times. We are not counting.

  Fig. 2 (a) shows the relationship between the number of instantaneous voltage drop occurrences and the economic loss incurred by the customer due to the occurrence of the instantaneous voltage drop, when lightning option trading is not used (broken line) and when lightning option trading is used ( A solid line) is schematically shown. FIG. 2B shows the relationship between the number of lightning strikes in an area where lightning strikes affect the customer and the amount the customer receives from the insurance company in a lightning strike option transaction.

  As indicated by a broken line in FIG. 2A, when the lightning strike option transaction is not used, the economic loss increases as the number of occurrences of the instantaneous voltage drop increases. On the other hand, as shown in Fig. 2 (b), when using lightning option trading, payment of option fee will occur until the number of lightning strikes reaches the prescribed number of exercises. Thereafter, the amount received increases as the number of lightning strikes increases. As a result, as indicated by the solid line in Fig. 2 (a), until the number of lightning strikes reaches the number of strikes, the loss increases by an option fee compared to the case where lightning strike options are not used. After that, the increase in loss will be suppressed even if the number of lightning strikes increases.

  FIG. 3 is an overall configuration diagram of a system according to the present embodiment. As shown in the figure, the system of this embodiment includes a lightning strike observation device 10, a lightning strike count device 20, a transaction condition setting device 30, and a power company system 40. Among these, the lightning strike count device 20, the transaction condition setting device 30, and the power company system 40 are each configured by a computer system.

  The lightning strike observation device 10 is a device that detects a lightning occurrence position and a lightning current value generated in various places. Specifically, for example, the lightning strike observation apparatus 10 includes a plurality of slave stations installed at various places and a master station that is communicably connected to these slave stations. The slave station detects the azimuth and magnitude of the electromagnetic wave generated by the lightning with the built-in antenna, and transmits the data including the electromagnetic wave azimuth and intensity to the master station. The master station determines the lightning strike position and the lightning current value based on the data transmitted from each slave station. In the present embodiment, the lightning strike position is expressed by latitude and longitude. For details of the lightning observation apparatus 10 having the above-described configuration, see, for example, “Development of Lightning Information Transmission System (Part 1)” Giken Technical Bulletin, Chugoku Electric Power Co., Inc., September 1991, No. 78

  Data including the lightning strike position and lightning current value detected by the lightning strike observation device 10 and the lightning strike date and time (hereinafter referred to as lightning strike data) is transmitted to the lightning strike count device 20 via a network, for example. The transmission of lightning strike data from the lightning strike observation device 10 to the lightning strike count device 20 may be performed every time a lightning strike occurrence is detected by the lightning strike observation device 10, or at certain time intervals. However, in any case, it is assumed that lightning strike data with an old lightning strike date / time is transmitted to the lightning strike count device 20 first. .

  The lightning strike count device 20 is operated and managed by a business operator (for example, a data provider) different from the owner of the lightning strike observation device 10, and the lightning strike data transmitted from the lightning strike observation device 10 is designated by the transaction condition setting device 30. The number of lightning strikes is counted as an index for lightning option trading based on the observed lightning strike conditions and customer locations. As will be described later, in the present embodiment, only lightning strikes that occur in an area corresponding to a customer point and that are equal to or greater than a specified current value (hereinafter referred to as a reference current value) are counted, and within a specified reference period. Even if lightning strikes continuously, the counting method is used to count only the first one, and the observation conditions including these reference current values and reference periods are set as part of the lightning option trading conditions. It is set by the device 30.

  In addition, even when a lightning strike observation apparatus 10 fails and lightning strike data cannot be transmitted, the lightning strike count device 20 cannot distinguish whether a lightning strike has occurred or the lightning strike observation apparatus 10 has a problem. Therefore, it is preferable to transmit the operation status of the lightning strike observation device 10 to the lightning strike count device 20 or the system of its manager so that the lightning strike count device 20 side can determine the malfunction of the lightning strike observation device 10. .

  The transaction condition setting device 30 is operated and managed by a financial institution such as an insurance company, for example, and receives input of transaction conditions set based on a lightning option transaction contract with a power company customer. The transaction conditions include a reference current value, a reference period, a customer point (that is, a customer location), a contract period, the number of options exercised, the amount received per lightning strike, and the maximum amount received.

  Hereinafter, the structure of the lightning strike count device 20 and the transaction condition setting device 30 will be described in detail. First, the lightning strike count device 20 will be described.

  As shown in FIG. 3, the lightning strike count device 20 includes a lightning strike data acquisition unit 200, an observation condition acquisition unit 202, an observation target area acquisition unit 204, a count processing unit 206, and a lightning strike data storage unit 208. , A post-processing lightning strike data storage unit 209 and an observation condition storage unit 210. The functional units 200 to 206 are realized by the CPU of the computer system constituting the lightning strike count device 20 executing a program. The storage units 208, 209, and 210 are provided on a storage device such as a hard disk device. Note that the observation condition acquisition unit 202 and the observation target area acquisition unit 204 constitute a count condition acquisition unit 205.

  The lightning strike data acquisition unit 200 acquires the lightning strike data transmitted from the lightning strike observation device 10 and stores the obtained lightning strike data in the lightning strike data storage unit 208. The lightning strike data stored in the lightning strike data storage unit 208 is supplied to the count processing unit 206.

  FIG. 4 shows an example of lightning strike data stored in the lightning strike data storage unit 208. As shown in the figure, the lightning strike data storage unit 208 sequentially accumulates lightning strike data including the lightning strike date and time, the lightning strike current value, and the lightning strike position for the lightning strikes observed so far.

  The observation condition acquisition unit 202 acquires a reference period, a reference current, a contract period, and a customer point out of the transaction conditions from the transaction condition setting device 30 together with a transaction ID for each lightning strike option transaction. Then, the transaction ID and the customer point are supplied to the observation target area acquisition unit 204, and the reference period, the reference current, and the contract period are associated with the transaction ID and stored in the observation condition storage unit 210.

  Based on the customer point supplied from the observation condition acquisition unit 202, the observation target area acquisition unit 204 transmits a signal for inquiring about the lightning observation target area to the power company system 40. In other words, as mentioned above, the number of lightning strikes as an index for lightning derivative transactions must correspond to customer locations because it is necessary to count only the number of lightning strikes in areas where lightning strikes affect customer power transmission. The power company system 40 is inquired about the area to be observed. In this embodiment, as shown in FIG. 5, a rectangular area in which longitude and latitude are divided, for example, at 15-minute intervals is set, and an area number is given to each area. An area is specified. However, the method of setting the area is not limited to this, and the area may be divided by an appropriate method.

  The electric power company system 40 stores information representing a customer point and a power transmission route to the customer point in a database, and refers to this database to identify an observation target area corresponding to the customer point for which an inquiry has been made. Then, a signal including the area number of the observation target area is transmitted to the observation target area acquisition unit 204. An example of a method for extracting a power transmission line that may cause a customer to generate an instantaneous voltage due to a lightning strike is disclosed in Patent Document 1 (Japanese Patent Laid-Open No. 2003-47173). The observation target area acquisition unit 204 stores the area number of the observation target area acquired from the power company system 40 in this way in the observation condition storage unit 210 in association with the transaction ID.

  In addition, as described above, there may be a customer who suffers an economic loss even if a lightning strike does not affect power transmission, such as a golf course. In such a case, the observation target area can be determined without making an inquiry to the power company system 40.

  When the lightning strike data is supplied from the lightning strike data storage unit 208, the count processing unit 206 receives the reference period, the reference current, the contract period, and the area number of the observation target area for each transaction ID stored in the observation condition storage unit 210. Based on the above, the number of lightning strikes is counted. Here, the count processing of the number of lightning strikes by the count processing unit 206 will be described in detail.

  As mentioned above, lightning strikes tend to occur multiple times in succession, but after being affected by the first lightning strike, it takes a certain amount of time to recover from that effect. After the occurrence, the effects of lightning strikes immediately after it can be ignored. And since the time required to recover from the effect of lightning strikes varies depending on the customer's environment, how much lightning strikes should be ignored within a certain period should be set according to the customer. Therefore, in this embodiment, the concept of the reference time described above is introduced, and lightning strikes that occur within the reference time after the first lightning strike are not counted.

  FIG. 6 is a flowchart of a routine in which the count processing unit 206 according to the present embodiment performs a lightning strike count process. The routine shown in the figure is started for each lightning strike option transaction whenever lightning strike data is supplied from the lightning strike data storage unit 208 to the count processing unit 206. In the following, this routine will be described as being executed for a certain lightning strike option transaction CID (CID is a transaction ID of a lightning strike option transaction). In FIG. 6, tn represents the latest date and time when the occurrence of lightning strikes, and CT represents the number of times of lightning strikes.

  As shown in FIG. 6, when new lightning strike data is supplied from the lightning strike data storage unit 208, it is first determined in step 50 whether or not the lightning strike position included in the lightning strike data is within the observation target area. As a result, if a negative determination is made, it is not a lightning strike that is to be counted, so the current process ends. On the other hand, if an affirmative determination is made in step 50, then in step 52, the lightning strike date and time tc included in the lightning strike data is within the contract period of the lightning strike option transaction CID (that is, the lightning strike observation period), and It is determined whether or not the lightning current value is greater than or equal to the reference current value. As a result, if it is within the contract period and not less than the reference current value, the process of step 54 is performed next.

  In step 54, it is determined whether or not the latest lightning occurrence count date and time tn is earlier than the time point (tc-T0) that is earlier than the lightning strike date and time tc included in the lightning strike data by the reference time T0. As a result, if a negative determination is made, it is determined that the current lightning strike should be ignored since the reference time T0 has not elapsed since the occurrence of the lightning strike counted as the number of lightning strikes, and the process is immediately terminated. On the other hand, if an affirmative determination is made in step 54, next, in step 56, “1” is added to the number of lightning strikes CT, and in step 58, the latest lightning occurrence count date and time tn is set to the occurrence of the current lightning strike data. After the date / time tc is set, the process ends.

  The count processing unit 206 has a table that holds the correspondence relationship between the area number and the longitude / latitude range of the area as shown in the upper left of FIG. 5, and the lightning strike position is (longitude, latitude). Is obtained with reference to the above table, the area number of the area to which the lightning strike position belongs is obtained, and the lightning strike position is determined based on whether the area number matches any area number of the observation target area. Is determined to be within the observation target area.

  If it is determined in step 52 that the current lightning occurrence date and time tc is outside the contract period, and if the contract period has passed (yes in step 60), the count value CT of the number of lightning strikes in step 62 And the count value is supplied to the transaction condition setting device 30 together with the transaction ID. The supply of the number of lightning strikes to the transaction condition setting device 30 may be performed via a network, may be performed via an electronic recording medium, or may be manually performed by fax, document, e-mail, telephone, etc. It may be performed by communication means.

  The count process shown in FIG. 6 may be executed every time new lightning strike data is generated, or the lightning strike data accumulated every certain period (for example, every week or every month) is collected. You may go.

  The count processing unit 206 also executes the routine of FIG. 6 for the lightning strike data stored in the lightning strike data storage unit 208 in the past predetermined period (for example, 20 years), and observes the observation conditions (reference current value, reference Counts the number of lightning strikes per fixed period (for example, 1 week, 1 month, 1 year, etc.) based on the period and observation area), and processes the number of lightning strikes per fixed period in relation to the relevant transaction ID It is stored in the post lightning strike data storage unit 209. That is, it is not determined whether or not it is within the contract period in step 52 of FIG. Thus, the post-process lightning strike data storage unit 209 accumulates the number of lightning strikes for a certain period when counting is performed under the same conditions as the observation conditions of the corresponding transaction. Then, the data accumulated in the processed lightning strike data storage unit 209 is supplied to the transaction condition setting device 30 online via a network or via an electronic recording medium such as a CD-ROM, DVD, magnetic tape or the like. As will be described later, the transaction condition setting device 30 is used when calculating an option fee or the like for a lightning strike option transaction.

Next, the transaction condition setting device 30 will be described.
As illustrated in FIG. 3, the transaction condition setting device 30 includes functional units such as a transaction condition acquisition unit 300, a payment amount calculation unit 302, a lightning strike frequency distribution calculation unit 304, and an option fee calculation unit 306. These functional units 300 to 306 are realized by the CPU of the computer system constituting the transaction condition setting device 30 executing the program.

  The transaction condition acquisition unit 300 is a transaction condition set in a lightning strike option contract between a financial institution and a customer (that is, a contract period, a reference period, a reference current, a customer point, the number of exercises, a lightning strike once Per transaction, maximum received amount), and a transaction ID is assigned to the transaction conditions of each transaction.

  The amount-of-payment calculation unit 302, as described above, the number of lightning strikes supplied from the lightning strike counting device 20, the number of exercises among the transaction conditions acquired by the transaction condition acquisition unit 300, the amount received per lightning strike, and the maximum receipt The amount to be paid from the financial institution to the customer is determined based on the amount. Specifically, if the number of lightning strikes exceeds the number of strikes, the difference between the number of strikes and the number of strikes multiplied by the amount received per lightning strike (however, the maximum amount received is the upper limit) The amount to be paid from the financial institution to the customer.

  The lightning strike frequency distribution calculation unit 304 obtains data on the number of lightning strikes in the past predetermined period (for example, 20 years) stored in the post-process lightning strike data storage unit 209 in association with the corresponding transaction ID from the lightning strike frequency counting device 20. Then, based on the acquired data, the frequency distribution of the number of lightning strikes in the observation target area (the number of lightning strikes as an index of lightning option trading) is calculated. FIG. 7A shows an example of the frequency distribution of the number of lightning strikes. As shown in FIG. 7A, the frequency distribution is calculated with the horizontal axis representing the number of lightning strikes and the vertical axis representing the frequency (%).

  The option fee calculation unit 306 includes the frequency distribution of the number of lightning strikes calculated by the lightning strike frequency distribution calculation unit 304, the transaction conditions acquired by the transaction condition acquisition unit 300 (the number of exercises, the amount received per lightning strike, and the maximum amount received). ) And the expected value of the customer's receipt amount is calculated, and the option fee is calculated based on the expected value. For example, if the number of exercises is 400, the amount received per lightning strike is 500,000 yen, and the maximum amount received is 100 million yen, the relationship between the number of lightning strikes and the amount received by the customer is shown in FIG. It becomes street. Then, for each number of lightning strikes, the expected value of customer receipts is calculated by adding the amount of customer receipts multiplied by the probability obtained from the frequency distribution illustrated in FIG. 7A over the total number of lightning strikes. Then, the option fee is calculated by adding the margin according to the calculation error of the lightning frequency distribution and the fee of the financial institution to this.

  As described above, according to the system of the present embodiment, when counting the number of lightning strikes for lightning option trading using the number of lightning strikes as an index, the first 1 By adopting a counting method that counts only once, it is possible to obtain the number of lightning strikes corresponding to the economic loss suffered by the customer due to lightning strikes. Therefore, by performing a lightning strike option transaction based on the number of lightning strikes counted in this way, it is possible to calculate an appropriate payment amount to make up for the customer's loss due to the lightning strike.

  Moreover, in the said embodiment, since it was set as the structure which isolate | separates the lightning strike observation apparatus 10, the lightning strike count device 20, and the transaction condition setting apparatus 30, and they manage and manage them separately, the fairness of the number of lightning strikes is set. It can be secured and lightning option trading can be executed properly. The data provider that operates and manages the lightning strike counting device 20 makes the lightning strike data stored in the post-process lightning strike storage unit 209 public on, for example, the WEB site on the Internet so that the customer can view it, or The fairness of the data may be further improved by issuing a data certificate to the customer.

  By the way, in the said embodiment, although the case where this invention was applied to the lightning strike option transaction which used the number of lightning strikes as an index was described, it is not restricted to this, For example, swap payment etc. generate and receive money according to the number of lightning strikes Applicable when counting the number of lightning strikes in other derivative transactions. In addition to derivative transactions involving financial institutions, for example, when a contract is made between a power company and a customer to discount electricity charges according to the number of lightning strikes, the count of lightning strikes that provides the basis for the discount amount It can also be applied to.

It is a figure which shows an example of the relationship between the lightning strike frequency and the instantaneous voltage drop occurrence frequency. Fig. 2 (a) shows the relationship between the number of occurrences of instantaneous voltage drop and the economic loss suffered by the customer due to the instantaneous voltage drop, when lightning option trading is not used (broken line) and when lightning option trading is used (solid line).
