[0021]
Embodiments of the present invention will be described below with reference to the drawings.
[0022]
(First embodiment)
FIG. 1 is a system configuration diagram of a power system protection control system according to the first embodiment of the present invention. FIG. 2 is a diagram illustrating a configuration example of the power system protection control device illustrated in FIG. 1.
[0023]
As shown in FIG. 1, the protection control devices 21, 22,..., 2N installed in the substation 5 premises take the state of the power system 1 as an input, and perform an output for protecting or controlling the power system 1, The operation information is recorded, and the operation information is transmitted to the upper control station system 7 via the local LAN 4, the telecon slave station 3, and the transmission network 6. 2, the protection control device 21 (22,..., 2N) performs an operation related to the protection control function and an input / output unit 2a that performs state input / control output with the power system 1. It has a protection control calculation unit 2b and a transmission processing unit 2c that performs transmission / reception with a host device via the local area LAN 4, and further includes a mail transmission unit 2d.
[0024]
The protection control calculation unit 2b is also equipped with a constant monitoring / inspection function of the protection control device 21 (22,..., 2N), and can detect an abnormality of the own device. Operation information and device abnormality information of the protection control device 21 (22,..., 2N) are displayed on the CRT of the control station system 7 via the substation local area LAN 4, the telecon slave station 3, and the transmission network 6.
[0025]
The protection control arithmetic unit 2b passes the transmission information to the transmission processing unit 2c, and at the same time passes the transmission information to the mail transmission unit 2d. The transmission processing unit 2c transmits the received transmission information to the local LAN 4. The mail sending unit 2d sends the transmission information by mail according to a mobile phone number list registered in advance. Normally, unlike departments that deal with power system accidents and departments that deal with equipment abnormalities, the range of departments and parties to be contacted changes depending on the scale of the power system accident and the degree of equipment abnormality. The mobile phone number list is set so that the transmission destination can be changed according to. For example, a system operation person list and a system operation manager list to be notified when a system failure occurs, and a maintenance staff list and a maintenance manager list to be notified when an apparatus malfunctions are set.
[0026]
Next, the operation of the protection control device 21 (22,..., 2N) will be described taking as an example a case where a device abnormality has occurred. When the protection control calculation unit 2b detects an abnormality of the own device by the constant monitoring / inspection function, the protection control calculation unit 2b passes the device abnormality information to the transmission processing unit 2c and simultaneously sends the device abnormality information to the mail transmission unit 2d. In the mail transmitting unit 2d, a mobile phone number list corresponding to the content and degree of the apparatus abnormality information is registered in advance.
[0027]
The mail transmitting unit 2d selects a mobile phone number list according to the content / degree of the received device abnormality information, and transmits a device abnormality information mail to the selected mobile phone according to the mobile phone number list. For example, an e-mail containing the device error occurrence date and time, the name of the device that occurred, and the details of the error is sent to the maintenance personnel according to the maintenance personnel list, and the device failure occurrence date and time according to the maintenance administrator list is sent to the maintenance manager. An e-mail including the name of the generating device, the name of the maintenance staff who sent the e-mail and the e-mail address is sent.
[0028]
When maintenance personnel are working on shifts, maintenance personnel who work during the corresponding time zone on the day of the failure by registering a mobile phone number list for maintenance personnel in the form of a combination of a shift work table and a calendar It is also possible to send an email only to
[0029]
  According to the present embodiment, since mail is delivered directly from the protection control device 21 (22,... 2N) of the power system control protection system to the mobile phone normally held by each maintenance staff, information transmission time is shortened and transmission work is performed. Can be automated. In the conventional apparatus, when the transmission processing unit 2c fails, the telecon slave station or the control station system can only detect that there is an abnormality because the transmission from the protection control apparatus is interrupted. In the embodiment, the transmission processing unit 2c can be notified to the maintenance staff by e-mail that there is a failure but there is no other abnormality. Furthermore, since the mail transmission destination and the mail content can be changed according to the content and level of the transmission information, only the necessary content can be conveyed to the necessary person in an appropriate expression.For example, necessary information that is inevitably different between a person in charge and a manager among related parties can be organized and transmitted by mail. Moreover, in the power system protection control apparatus corresponding to both the systematic change and the apparatus abnormality in the event, it is possible to appropriately transmit e-mails to those corresponding departments. In these cases, since the information terminal list is utilized, the information terminal is selected smoothly.
[0030]
It is also possible to incorporate the e-mail function, fax function, and voice generation function via the Internet into the mail sending unit 2d, and to transmit device abnormality information by e-mail, fax, and voice. The destination may be a PHS, a public line telephone, a leased line telephone or the like instead of a mobile phone, or a combination thereof.
[0031]
(Second Embodiment)
A second embodiment will be described with reference to FIG. FIG. 3 is a diagram illustrating a configuration example of a protection control device according to the second embodiment that can be used in place of the protection control device 21 (22,..., 2N) illustrated in FIG. As shown in FIG. 3, the point that the mail transmitting / receiving unit 2e and the bulletin board unit 2f are added to the protection control device 21A (22A,... 2NA) is different from the embodiment shown in FIG.
[0032]
In order to explain the operation, the protection control calculation unit 2b passes the transmission information to the transmission processing unit 2c, and simultaneously transfers the transmission information to the mail transmission / reception unit 2e. The transmission processing unit 2c transmits the received transmission information to the local LAN 4. In the mail transmitting / receiving unit 2e, a mobile phone number list corresponding to the content and degree of the apparatus abnormality information is registered in advance.
[0033]
The mail transmission / reception unit 2e transmits transmission information by mail according to a mobile phone number list registered in advance, and at the same time writes the transmission mail information to the bulletin board unit 2f. The mail transmitting / receiving unit 2e receives an external mail, and writes the received mail information into the bulletin board unit 2f when the mail is a bulletin board write request.
[0034]
In addition, when the mail transmission / reception unit 2e determines that a mail received from the outside is a request for browsing the content recorded in the bulletin board unit 2f, the mail transmission / reception unit 2e reads the browsing request content from the stored content of the bulletin board unit 2f and makes a bulletin board browsing request. Return to mobile phone. The bulletin board 2f stores the received mail information in chronological order. The operation of each component other than those described above is the same as that of the first embodiment.
[0035]
Next, the operation of the protection control device 21A (22A,..., 2NA) will be described taking as an example the case where a device abnormality has occurred. When the protection control calculation unit 2b detects an abnormality of the own device by the constant monitoring / inspection function, the protection control calculation unit 2b passes the device abnormality information to the transmission processing unit 2c, and also sends the device abnormality information to the mail transmission / reception unit 2e. The mail transmission / reception unit 2e selects a mobile phone number list according to the contents / degree of the received device abnormality information, and transmits a device abnormality information mail to individual maintenance personnel and maintenance managers according to the mobile phone number list. At the same time, the mail transmitting / receiving unit 2e writes the device abnormality information to the bulletin board unit 2f.
[0036]
The maintenance staff who has received the device abnormality information performs maintenance work according to the content, and sequentially sends the content to the corresponding device by e-mail. The mail transmission / reception unit 2e that has received the response work information mail from the maintenance staff writes the received maintenance response work information to the bulletin board unit 2f. For example, move / arrival to the substation where the abnormality occurred, contact the equipment manufacturer and request for the arrangement / delivery of necessary equipment, completion of recovery work at the substation where the abnormality occurred, and the date / time and name of the person in charge 4). The maintenance manager checks the progress of the maintenance work by accessing the bulletin board unit 26 of the apparatus.
[0037]
If the maintenance work is not completed within the working hours, it will be handed over to the next worker, but the handed over maintenance staff will access the bulletin board 2f of the equipment, and the equipment that caused the work It is possible to check the occurrence status of abnormalities and the progress of maintenance work at any time. In addition, the maintenance staff who has taken over writes his / her work contents on the bulletin board 2f.
[0038]
According to the present embodiment, since the mail is delivered directly from the power system control protection system to the mobile phone normally held by each maintenance staff, it is possible to shorten the time for information transmission and to automate the transmission work. The progress of the work can be disclosed to people other than the maintenance personnel who are actually working.
[0039]
In this embodiment, the transmission means is a mobile phone mail, but a PHS, a public line telephone, a leased line telephone or the like is also possible.
[0040]
(Third embodiment)
A third embodiment will be described with reference to FIG. FIG. 5 is a system configuration diagram of a power system protection control system according to the third embodiment of the present invention. The same reference numerals are given to the components already described in FIG. As shown in FIG. 5, the point that the protection control device 201 (202,..., 20N) does not have the mail function and the point that the substation server 8 is provided in the substation 5a are the same as the first and second embodiments. Different.
[0041]
Operation information and device abnormality information of the protection control device 201 (202,..., 20N) are displayed on the CRT of the control station system 7 via the substation local area LAN 4, the telecon slave station 3, and the transmission network 6. Further, the operation information and device abnormality information of the protection control device 201 (202,..., 20N) are also passed to the substation server 8. The substation server 8 has a mail transmission / reception function and a Web server function.
[0042]
When the substation server 8 receives the operation information and device abnormality information of the protection control device 201 (202,..., 20N), the substation server 8 operates according to the pre-registered e-mail address list. At the same time as sending the information by e-mail, the detailed information of the transmission contents is converted into a Web page and stored. The mail is received via the transmission network 61 to the operation person's personal computer 9 and the maintenance person's personal computer 10 which are personal computers used by the system operation person and the maintenance person.
[0043]
FIG. 5 shows only one operation person-in-charge personal computer 9 and one maintenance person personal computer 10, but it is assumed that these are connected by the number of system operation persons and maintenance personnel. The operation of each component other than those described above has already been described.
[0044]
Next, the operation of this embodiment will be described taking as an example the occurrence of a systematic change. When the protection control calculation unit 201b of the protection control device 201 (202,..., 20N) detects the occurrence of systematic change by the input from the input / output unit 201a, it passes the systematic change occurrence information to the transmission processing unit 201c. Thereafter, the protection control calculation unit 201b collects current / voltage information before and after the occurrence of the systematic change, operation information of the protection relay, and the like as systematic change detailed information and passes it to the transmission processing unit 201c. (Here, 201a, 201b, and 201c have already been described with reference to FIG. 13.)
[0045]
The transmission processing unit 201 c transmits the systematic change occurrence information to the telecon slave station 3 and the systematic change occurrence information and the systematic change detailed information to the substation server 8 via the local area LAN 4. The telecon slave station 3 transmits systematic change occurrence information to the control system 7 via the transmission network 6. The substation server 8 sends the received systematic change occurrence information to the parties concerned via the transmission network 61 according to the e-mail address list, and converts the systematic change detailed information into a Web page and stores it. The address of the systematic change detailed information Web page is put in the mail distributed to the parties concerned (see FIG. 6).
[0046]
In FIG. 6, http://nt3.relayserve.com/pspc/relay and others are Web page addresses (URL: uniform resource locator). A person who has received the systematic change occurrence information by e-mail can easily view the systematic change detailed information by the address of the Web page included in the e-mail. In the example shown in FIG. 6, it is shown that detailed operation information of the protective device in a power line accident, fault location information, and oscilloscope waveform information at the time of the accident are provided.
[0047]
According to the present embodiment, an e-mail arrives directly from the power system protection control system to a personal computer used by a grid operator or maintenance staff in daily work, and detailed information on systematic changes is received from the browser of the personal computer that received the e-mail. Since it can be easily seen, it is possible to shorten the time for information transmission and to automate the transmission work.
[0048]
In this embodiment, e-mail and a web page are used. However, the present embodiment can be similarly realized by a mobile phone mail or an electronic bulletin board.
[0049]
In the above description, the operation has been described by taking as an example the occurrence of a systematic change, but the same applies to the abnormality information of the protection control device 201 (202,..., 20N). In the first and second embodiments, for example, in the case of a failure such as power loss of the own device, the abnormality information of the device cannot be transmitted by e-mail. However, if configured as in this embodiment, the abnormality generating device is stopped. Even if it is in the state, the substation server 8 can send an e-mail that an abnormality has occurred.
[0050]
In order for the substation server 8 to detect an abnormal state of the protection control device 201 (202,..., 20N), a periodic health as a method in which a server connected to the LAN checks each device connected to the LAN. It is possible to use techniques such as checking and DI contact passing, and since the contents of these techniques are publicly known, description thereof is omitted here.
[0051]
(Fourth embodiment)
A fourth embodiment will be described with reference to FIGS. FIG. 7 is a system configuration diagram of a power system protection control system according to the fourth embodiment of the present invention. FIG. 8 is a diagram illustrating a configuration example of the protection control device illustrated in FIG. 7. As shown in FIG. 8, the mail transmitting unit 2d is provided in the protection control device 21B (22B,...), And the transmission port is connected to the local LAN 4, which is different from the first embodiment. As shown in FIG. 7, transmission from the substation 5b through the transmission network 61 is performed by the router 13 provided in the substation 5b.
[0052]
The protection control arithmetic unit 2b passes the transmission information to the transmission processing unit 2c, and at the same time passes the transmission information to the mail transmission unit 2d. The transmission processing unit 2 c transmits the received transmission information to the control center system 7 via the local area LAN 4, the router 13, and the transmission network 61. TCP / IP (transmission control protocol / internet protocol) transmission can be applied to transmission from the protection control device 21B (22B,...) To the control center system 7.
[0053]
On the other hand, the mail transmitting unit 2d transmits transmission information by e-mail according to a pre-registered e-mail address list. As in the first embodiment, there are four types of e-mail address lists: a system operator list and a system operation manager list to be contacted when a system failure occurs, a maintenance staff list and a maintenance manager list to be contacted when a device malfunctions For example, a list is set so that the transmission destination can be changed in accordance with the content and level of transmission information.
[0054]
Further, it is possible to add urgent or importance information to the mail according to the content / degree of transmission information. For example, “emergency” is added to the head of the mail title in the case of a serious device failure, and “emergency” is added in the case of a minor failure. In the case of a re-closing failure due to a main system accident or a supply trouble due to a power distribution system accident, “emergency” is added to the head of the mail title, and “emergency” is added in the case of other accidents.
[0055]
The e-mail transmitted by the mail transmitting unit 2d reaches the operation personal computer 9, the maintenance personal computer 10, the operation manager personal computer 11, and the maintenance manager personal computer 12 via the local LAN 4, the router 13, and the transmission network 61. Although only one of these is shown in FIG. 7, the operation manager personal computer 9, the maintenance person personal computer 10, the operation manager personal computer 11, and the maintenance manager personal computer 12 are connected to the system operation person and the maintenance person, and the operation management. It is assumed that there are as many connections as there are administrators and maintenance managers. Since e-mail is also a TCP / IP-based transmission application, the local LAN 4, router 13, and transmission network 61 with a TCP / IP transmission function can be shared. The operation of each component other than those described above is the same as that already described.
[0056]
Next, the operation of this embodiment will be described by taking as an example a case where a serious failure has occurred in the protection control device 21B (22B,. When the protection control calculation unit 21B (22B) detects an abnormality of its own device by the constant monitoring / inspection function, it passes the device serious failure information to the transmission processing unit 2c and also sends the device serious failure information to the mail transmission unit 2d. . Since the received information is device serious failure information, the mail transmission unit 2d sends an e-mail with “emergency” added to the head of the mail title according to the maintenance staff list and the maintenance manager list.
[0057]
The transmitted e-mail reaches the personal computers 10 and 12 that are used for daily work by maintenance personnel and maintenance managers. Maintenance personnel and maintenance managers can immediately determine the urgency level of an incoming mail by the “emergency” added to the title of the mail when the mail arrives, and can immediately start the response work.
[0058]
According to the present embodiment, since a mail is delivered directly from the protection control device 21B (22B,...) To the personal computers 9, 10, 11, 12 used by the maintenance staff, maintenance managers, etc. Time can be shortened and transmission work can be automated. Further, in the conventional apparatus, when the transmission processing unit 2c fails, the control center system 7 can detect only that there is an abnormality due to the transmission from the protection control apparatus 21B (22B,...) Being interrupted. In this embodiment, it is possible to notify the maintenance staff by e-mail that “the transmission processing unit 23 has failed but there is no other abnormality”. Furthermore, since the mail transmission destination and the mail contents can be changed according to the contents and level of the transmission information, the urgency and importance of the information can be conveyed in an appropriate expression.
[0059]
Note that. In the present embodiment, the mail delivery to the personal computers 9, 10, 11, 12 is performed, but the same can be realized by the mail delivery to the mobile phone.
[0060]

[0066]
Similarly, when the protection control calculation unit 2b of the protection control device 22D detects a failure of its own transmission processing unit 2c by the self-monitoring function, the protection control device 21D receives “protection control” via the device serious failure notification signal 32. An email indicating that a major failure has occurred in the device 22D is transmitted. The operations of the constituent elements other than those described above are the same as those in the fifth embodiment.
[0067]
According to this embodiment, in addition to the same effect as the fifth embodiment, the fifth embodiment has the disadvantage that information from the protection control device is interrupted due to a failure of the transmission processing unit 2c. This can be resolved by notification of device failure information from the device.
[0068]
In the present embodiment, the transmission processing unit 2c failure has been described as a major failure. However, the device power loss or the device function loss due to the protection control calculation unit 2b failure is added to the device serious failure notification signal, or the device serious failure notification. A plurality of signals can be used to notify the content / degree of failure information in more detail.
[0069]
【The invention's effect】
As described above in detail, according to the present invention, systematic changes and device abnormalities of the power system protection control device are directly and individually transmitted from the power system protection control device to the parties concerned via mail. This eliminates the need for conventional communication and makes it possible to quickly cope with a change in the power system or an abnormality in the power system protection control device.
[0070]
In addition, according to the present invention, it is possible to view information related to systematic changes and device abnormalities of the power system protection control device and to share information related to the progress status of corresponding work among related parties through an electronic bulletin board. It is possible to improve work efficiency at the time or when the power system protection control device is abnormal.
