Description

  The present invention relates to a distribution line system display system, and more specifically, a distribution line having a street map display function for displaying a distribution line system on a map and a skeleton display function for displaying the distribution line system in a skeleton format. The present invention relates to a system display system.

  The electric power company monitors the distribution line facilities and switches the distribution line system by remote control according to changes in the situation such as the occurrence of a failure. In such a system (distribution line management system) for monitoring and remotely controlling distribution line equipment, a distribution line display function for selecting a distribution line section to be monitored and displaying the status of the monitored section. Is required. Distribution line status display is, for example, a street map display method that displays the distribution line section specified by the operator on a map, or a skeleton display system that displays the logical configuration of the specified distribution line section as a skeleton figure Is done by.

  Conventional distribution line monitoring / control systems include a distribution line system display system that consists of a road map database and a road map display computer, and a skeleton display database. Some have a distribution line system display system dedicated to skeleton display, consisting of a skeleton display computer.

nothing special.

  The street map display of the distribution line system has an advantage that the physical arrangement of the distribution line section to be monitored can be confirmed on the map, so that the fault range and the range of influence by switching the system can be intuitively grasped. However, in the street map display, distribution line systems are displayed overlaid on the map, so if you try to display a wide range of distribution line systems on the screen, the display screen size, map reduction and definition, topographic For reasons such as restrictions, it is difficult to confirm the entire designated distribution line system on the same display screen. Therefore, when the distribution line part to be noted is off the display screen, it is necessary to perform an operation of searching for the target facility or section by switching or scrolling the screen.

  The street map display method has become widespread as a monitoring and control system suitable for monitoring distribution lines in urban areas where distribution facilities are densely arranged in a relatively narrow area, but when a failure occurs in an area where buildings are densely packed For an unfamiliar operator, it may take time to search for a target facility on the street map display screen, and therefore, combined use with a skeleton display is desired.

  On the other hand, in the skeleton display, the specified distribution line section can be displayed in a logical configuration diagram without being restricted by the physical expansion of the distribution line system. There exists an advantage which can display the detail of a structure and a local distribution line area on a display screen easily. For this reason, the skeleton display method is widely used as a monitoring / control system suitable for monitoring distribution lines in areas where distribution facilities are relatively discretely arranged in a wide range. However, even when the skeleton display method is adopted, it is desired to grasp the physical arrangement of the distribution facilities by displaying the street map according to the situation of the monitoring target section.

  In the distribution line monitoring and control system, if you want to combine the advantages of street map display and skeleton display with the conventional method, you need to have both a street map display dedicated system and a skeleton display dedicated system, and the system scale is large. There is a problem that the maintenance of the database accompanying the change of the distribution line system requires a lot of work. In addition, even if a street map display computer and a skeleton display computer are used together and a street map display and a skeleton display are realized by switching screens, the street map database and the skeleton display database are used in the conventional method. Therefore, there is a problem that the database becomes large and requires maintenance for those.

An object of the present invention is to provide a distribution line system display system capable of providing a street map display screen and a skeleton display screen without increasing the system scale.
Another object of the present invention is to provide a distribution line system display system having a street map display function and a skeleton display function taking into account the geographical positional relationship of distribution facilities.

  In order to achieve the above object, the present invention is necessary for an operator operation terminal provided with a display device, a facility database storing distribution facility information used for controlling a distribution line system, and a street map display of the distribution line system. In a distribution line system display system comprising a street map database storing information, a storage device for storing distribution line skeleton display information, and a distribution line system display computer, the above distribution line system display In response to the street map display command from the operator operation terminal that designates the distribution line section, the computer generates the street map display data for the designated distribution line section based on the accumulated information in the street map database. In response to a skeleton display command from the operator operation terminal that designates one means and a distribution line section, designated distribution based on accumulated information in the facility database A data file necessary for creating the skeleton display screen of the section is generated and stored in the storage device, and the data file stored in the storage device is used to display the skeleton of the designated distribution line section. And third means for generating data.

  In a preferred embodiment of the present invention, the second means generates a data file for skeleton display based on accumulated information of both the facility database and the street map database. Specifically, the second means obtains the coordinate information of the distribution facility that is a constituent element of the designated distribution line section from the street map database, and reflects the coordinate information on the arrangement of each distribution facility on the skeleton display screen. Generate a data file for skeleton display.

  Another feature of the distribution line system display system according to the present invention is that, when the generation of the skeleton display data file is completed by the second means, the third means is automatically activated so that the skeleton display command from the operator is obtained. In response, the generation of the data file for displaying the skeleton and the generation of the screen data for displaying the skeleton using the data file are continuously executed.

  In one embodiment of the present invention, the second means determines whether or not the skeleton display data of the distribution line section designated by the skeleton display command already exists in the storage device, and if it exists, a new data file If the third means is activated without generating, the skeleton display data file in which the storage device exists is invalidated to generate a new data file. Three means are activated.

  According to the present invention, a street map display computer and a skeleton display computer are used together, and a data file for skeleton display is automatically generated as necessary. The hardware scale can be reduced. In addition, since the data file for skeleton display is automatically generated, even if the distribution line system is changed or expanded, it is only necessary to change the equipment database and the street map database, thus facilitating data maintenance. .

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a block diagram showing an embodiment of a distribution line system display system according to the present invention.
The distribution line system display system of the present embodiment is applied to a distribution system management system, and is an operator operation terminal including a distribution line system monitoring / control computer 1, a distribution line system display computer 2, and a display device 4 ( Operation console 3). These devices are interconnected by a network 5 such as a LAN.

  The network 5 stores a facility database 6 storing various data including distribution line system configuration information and state information, and various data necessary for displaying the distribution line system on a map as a street map. A street map database 7 is connected to a storage device 8 for storing skeleton display data necessary for displaying the distribution line system in the skeleton format.

  The monitoring / control computer 1 is connected to the distribution line system via a communication device (not shown). For example, when a failure occurs in a distribution facility such as a substation, an alarm is given to the display device 4 via the console 3. While outputting information, the failure state is registered in the data entry corresponding to the failure facility stored in the facility database 6.

  When the operator designates a distribution line section (distribution line name) and inputs a street map display command from the console 3, the distribution line system display computer 2 is based on the accumulated information in the facility database 6 and the street map database 7. A street map display routine 10 for generating screen data for displaying a street map of the distribution line system and outputting it to the display device 4 via the console 3, and a skeleton display command specifying the distribution line name from the console 3 When there is, a skeleton display data file generation routine 20 that automatically generates a skeleton display data file for the designated distribution line section based on the storage information in the facility database 6 and the street map database 7 and stores it in the storage device 8. Based on the above skeleton display data file, the screen data for distribution line skeleton display of the specified distribution line section is generated and And a skeleton display routine 30 to be output to the shown apparatus 4.

FIG. 2 shows an example of the distribution line system selection screen 40 output to the display device 4.

And a street map display designation button 43 and a skeleton display designation button 44. The operator selects (specifies) a specific distribution line name to be observed from among a plurality of distribution line names displayed in the distribution line name list 41, for example, and then selects a street map display designation button 43. And click one of the skeleton display designation buttons 44.

  FIG. 3 shows that the distribution line system display computer 2 executes the street map display routine 10 in response to a street map display command generated when the operator selects the street map display designation button 43 on the distribution line system selection screen 40. An example of the street map display screen 50 output to the display device 4 is shown. FIG. 4 shows a skeleton display that the distribution line system display computer 2 executes the skeleton display routine 30 and outputs to the display device 4 in response to a skeleton display command generated when the skeleton display designation button 44 is selected. An example of the screen 55 is shown.

  The street map display screen 50 displays the connection relationship of the distribution facilities in the distribution line section having the specific distribution line name A selected from the distribution line name list 41 as a layout map on the map. On the screen 50, a skeleton display switching button 51 for instructing switching to the skeleton display screen 55 and a return for instructing switching to the original screen, for example, the distribution line system selection screen 40 shown in FIG. A button 52 is provided. The actual system includes keys for enlarging / reducing display contents, mode switching, scrolling, etc., but these are omitted in the drawing for the sake of simplicity.

  The street map display screen 50 is generated based on the map information and distribution line system map data prepared in the facility database 6 and the street map database 7. The map is composed of a plurality of mesh areas, and the street map database 7 is required for displaying the board layer information and distribution line system diagram required for forming a general map corresponding to each mesh area. Specific layer information is stored.

  The board layer information is composed of a plurality of layers divided for each map component, such as roads, city blocks, administrative district boundaries, railways, rivers, houses, names associated with them, and symbols. Of the board layer information, information on the layer suitable for the background of the distribution line system is selectively used for the street map display. Similar to the board layer information, the specific layer information is also stored in multiple layers of information such as equipment symbols such as electric wires and switches constituting the distribution line system, character strings attached to each symbol, coordinate values, etc. Yes.

  In the example shown here, the distribution line section having the distribution line name A is a link that becomes a connection point between the main line switches (black triangle marks) SW1 to SW4 and the adjacent distribution line section having another distribution line name. It is represented by switches (open square marks) SW21, SW31 and distribution lines connecting these switches. Elements that are found to be in a fault state from the equipment database 6 are displayed so that they can be distinguished from other elements by changing their colors, for example. Here, only the automatic switch that can be remotely operated from the monitoring / control computer 1 is shown, and the manual switching type switch that exists between the automatic switches is excluded from the display target. By switching, it is possible to display a detailed distribution line structure including a manual switching type switch.

  In the following description, a distribution line section between a plurality of adjacent main line switches or between adjacent main line switches and linkage switches is referred to as a “main line section” and includes a manual switch. A distribution line section between adjacent switches in the configuration will be referred to as a “minimum section”. Each trunk line section and minimum section are assigned a trunk section system number and a minimum section system number as identifiers.

  The skeleton display screen 55 shown in FIG. 4 displays the connection relationship of the components (SW1 to SW31) of the distribution line section having the specific distribution line name selected from the distribution line name list 41 in the skeleton format. . The skeleton display screen 55 is provided with a street map display switching button 56 for instructing switching to the street map display screen 50 and a return button 57 for instructing switching to the original screen. In the distribution line system display system of the present invention, in consideration of the element type and the positional relationship on the map, on the skeleton display screen 55, the group of components on the main trunk line (SW1, SW2, SW4, SW41 in FIG. 4) is displayed. The components (SW1 to SW1) are arranged on the reference axis in the horizontal direction and arranged in order of priority from the inside to the outside with respect to the reference axis, the components (SW3, SW31, SW21) of each section branched from the main trunk line. The display position of SW31) is determined.

  FIG. 5 shows an example of the configuration of the equipment database 6. In the present embodiment, the equipment database 6 includes a distribution line switch list file 61, a switch equipment object file 62, a minimum section equipment object file 63, a trunk section number state file 64, and other information files 65. And are prepared.

  In the distribution line switch list file 61, for example, as shown in FIG. 6, a plurality of switch system numbers 611 (611-1) corresponding to the distribution line system numbers 610 (610-1 to 610-n). ~ 611-m). The distribution line system number 610 corresponds to the distribution line name selected in the distribution line name list 41 described above, and the switch system numbers 611-1 to 611-m are distribution lines specified in the distribution line name list. The system number of the several switch (a manual switch is included) used as the component of a section is shown.

  For example, as shown in FIG. 7, the switch equipment object file 62 corresponds to the switch system number 620 (620-1 to 620-i), the switch type 621, the power supply side minimum section system number 622, and , A load side minimum section system number 623 and other information 629 such as status information. The switch type 621 indicates a distinction between a rising switch, a main line switch, a link switch, other switches (such as a manual switch), and the like in which the switch is at the start position of the designated distribution line section. The switch system numbers 620-1 to 620-i correspond to the switch system numbers 611 registered in the distribution line switch list file 61.

  For example, as shown in FIG. 8, the minimum section equipment object file 63 corresponds to the minimum section system number 630 (630-1 to 630-j), the section type 631, the assigned distribution line number 632, and the adjacent opening / closing. The machine system number 633 (633-1 to 633p) and the main trunk section number 634 are shown. Here, the section type 631 indicates whether the minimum section is a main line of a distribution line or a lead-in line to a general household.

  The trunk section number state file 64 defines, for example, a load side trunk section number 641 and other information 642 corresponding to the switch system number 640 (640-1 to 640-i) as shown in FIG. ing. Here, the switch system number 640 (640-1 to 640-i) corresponds to the switch system number 620 (620-1 to 620-i) registered in the switch facility object file 62.

FIG. 10 shows an embodiment of a skeleton display data file generation routine 20 executed by the distribution line system display computer 2 prior to execution of the skeleton display routine 30 when a skeleton display command is received from the console 3.
In the skeleton display data file generation routine 20, the distribution line system number (hereinafter referred to as the designated distribution line number) corresponding to the distribution line name designated on the distribution line system selection screen 40 is specified (step 200), and then It is determined whether or not a skeleton display data file having a designated distribution line number has already been created in the storage device 8 (201). If the data file of the designated distribution line number has already been created in the storage device 8, the skeleton display routine 30 is activated (213), and this routine 20 is terminated.

  If there is no skeleton display data file having the specified distribution line number in the storage device 8, the unnecessary data file existing in the storage device 8 is cleared (202), and then the distribution line switch list file shown in FIG. Referring to 61, the switch system number corresponding to the designated distribution line number is acquired (203). Thereafter, referring to the switch equipment object file 62 shown in FIG. 7, the minimum section system numbers on the power supply side and the load side corresponding to the respective switch system numbers are specified (204).

  As shown in FIG. 11, for example, as shown in FIG. 11, the distribution line section having the designated distribution line number includes a rising switch SW1, a main line switch SW2 to SW6, a linkage switch SW31 to SW61, and a manual switch MS11 to MS22. Assume a section. In this case, the designated distribution line section includes main line sections S1 to S6. In addition, the main line section S1 includes minimum sections M11, M12, and M13, and the main line section S2 includes minimum sections M21 and M22. Actually, the other main line sections S3 to S6 include manual switches, but are omitted here for simplification. In this case, for example, when focusing on the switch SW2, the section M13 between the switch SW2 and the manual switch MS12 is the minimum section on the power supply side, and the section M21 between the switch SW2 and the manual switch MS21 is on the load side. Is the minimum interval.

  In the skeleton display data file generation routine 20, the minimum section equipment object file 63 shown in FIG. 8 is referred to based on the minimum section system number specified in step 204, and the power supply side and load side of each switch are set. The system number of the adjacent switch and the main trunk section number are specified (205).

For example, when attention is paid to the switch SW2 in FIG. 11, the system number of the adjacent switch MS12 on the power supply side is found from the minimum section facility object file 63 based on the system number of the power supply minimum section M13, Based on the system number of the minimum section M21, the system number of the adjacent switch MS21 on the load side is determined. Thereafter, referring to the trunk section number state file 64 shown in FIG. 9, the load side trunk section number of each switch is specified (206).
The data block of FIG. 14 which shows the adjacent switch group and the identification information of an adjacent section accompanying the number 611 (6111-1 to 611-m) of each switch included in the designated distribution line section by the above processing. 600 is obtained.

  In this embodiment, the switch system numbers 611-1 to 611-m are grouped based on the trunk section numbers 634 and 641 indicated by these data blocks 600, and as shown in FIG. 15, the trunk section number 81 (81 −1 to 81-n), switch system numbers 82 (82-1, 82-2,...) Are arranged in numerical order, and each switch system number includes switch type 821 to other information 829. A data file 80 having a format with an entry is created and stored in the storage device 8 (207).

  Next, coordinate information on the map corresponding to the system number 82 of each switch is retrieved from the unique layer of the street map database 7 and added to the data file 80 as coordinate information 830 (208). Further, the number of main line switches connected to the load side of each switch is counted and added to the data file 80 as the load side connection main line switch number 831 (209). For example, in the distribution line section shown in FIG. 11, when paying attention to the main line switch SW1, the load side connection main line switches are SW2 to SW6, and the load side connection main line switch of the main line switch SW2 is SW3. Two SW4 and the load side connection main line switch of the main line switch SW5 are one SW6.

  Next, using the coordinate information 830 of each main line switch, a vector of each main line switch with the power supply side switch as a base point is calculated for each main line section, and the resultant vector is used as a reference vector for each main line section. (210). For example, as shown in FIG. 12, when the trunk section S1 is formed by the switches SW1, SW2, and SW5, the reference vector of the trunk section S1 is the vector of the switch SW2 obtained with the power supply side switch SW1 as a base point. This is a combined vector V1 of V12 and the vector V15 of the switch SW5.

  In this embodiment, for each main line switch, a relative angle between each switch vector (for example, V12, V15) and a reference vector (for example, V1) is obtained, and this is set as a relative angle 832 in the data file 80. It is added (211). Thereafter, the priority of each section (switch) is determined according to the skeleton display rule described below, and the data entry of the switch system number belonging to the main section is rearranged according to the priority (212). Thus, since the automatic generation of the data file for skeleton display is completed, the skeleton display routine 30 is started (213), and the data file generation routine 20 is terminated.

FIG. 13 shows the relationship between the priority and the arrangement on the skeleton screen.
In this embodiment, when the switches SW04 of the main trunk section are arranged on the horizontal reference axis with the rising switch SW01 as a base point on the skeleton screen, a switch group (or trunk section) having a high priority is arranged. Determines the priority of each display element so as to be closer to the reference axis and away from the reference axis as the priority decreases. Further, in this embodiment, the trunk line switch group belonging to each trunk line section is distributed to the upper side and the lower side of the reference axis by the relative angle 832.

  In each trunk section, for example, the switch located on the left side (counterclockwise) from the reference vector is distributed to the upper side of the reference axis, the switch located on the right side (clockwise) from the reference vector is distributed to the lower side of the reference axis, Among the switches belonging to the upper side, the switch with the highest priority is arranged on the reference axis. The upper and lower side sorting results with respect to the reference axis are registered in each data entry of the data file 80, for example, as an array determination bit 820 shown in FIG.

In determining the priority of each switch, for example, the following rules (1) to (7) are applied in the sections other than the terminal section, and the rules (1) and (5) to (7) are applied in the terminal section. Apply.
(1) Priority is given to the smaller relative angle with respect to the reference vector. (2) Priority is given to the larger number of sections connected to the switch (the number of load-side connected main line switches). (3) Main line switch>SVR> For classification Switch (4) Small time> Large time (5) Automatic switch> Manual switch (6) Prioritize the smaller switch system number (7) Overhead switch> Underground switch Figure 16 shows the street map FIG. 17 shows an example of a skeleton display screen generated by the skeleton display routine 30 in accordance with the skeleton display data file 80 described above.

  In FIG. 16, numbers 1 to 4 surrounded by circles represent trunk line section numbers, and V1 to V4 represent reference vectors in each trunk section. In the trunk section 1, the trunk switches SW2 and SW3 exist, but the trunk switch SW2 having a smaller relative angle with respect to the reference vector V1 has priority, and therefore, as shown in FIG. Arranged on the axis. Further, from the value of the relative angle with respect to the reference vector, the trunk line switch SW3 and the linkage switch SW11 are allocated to the upper side of the reference axis, and the trunk line switch SW3 is placed at a position prioritized over the linkage switch SW11 by the rule (2). Be placed.

  In the main line section 2 starting from the main line switch SW2, the main line switch SW4 is arranged on the reference axis according to the rule (2), and the link switch SW21 is located below the reference axis from the value of the relative angle to the reference vector. Be placed. In the main line section 4 having the main line switch SW4 as a base point, since there is only one corresponding switch, the linkage switch SW41 is arranged on the reference axis. Similarly, also in the main line section 3 with the main line switch SW3 as a base point, since the corresponding switch is only the link switch SW31, the link switch SW41 is arranged on the same axis as the main line switch SW3.

  In the case of the distribution line section, the data file 80 prepared in the storage device 8 stores the switch system number and the data entry in the order of the switches SW2, SW3, SW11 in association with the main section 1. A bit value indicating that the data should be arranged on the upper side of the reference axis is given to the arrangement determination bits 820 of these data entries. Also, accompanying the main section 2, the switch system numbers and data entries are stored in the order of the switches SW4 and SW21. The array determination bit 820 of the switch SW4 is the upper side, the array determination bit 820 of the switch SW21. Is assigned a bit value indicating the lower side. In the data entry of the switches SW31 and SW41 associated with the main line sections 3 and 4, a bit value indicating the upper side is given to the array determination bit 820.

  In the above-described optimal embodiment of the present invention, the skeleton display data file generation routine 20 acquires the coordinate information of the switches included in the designated distribution line section from the street map database 7, and each of the switches indicated by the coordinate information is indicated by the coordinate information. Although the display position of each switch and section on the skeleton display screen is determined in consideration of the physical positional relationship, the position coordinates of each switch are not essential requirements in the present invention. That is, a data file for skeleton display is generated based only on the equipment database 6 and the priority (display position) of each switch and section is determined according to the priority determination rules (2) to (7) except (1). May be. In this case, since the sequence determination bit 820 is lost from the data file 80, the skeleton display screen arranges the trunk section having the largest number of subsequent sections on the reference axis, and in order of priority on the lower side (or upper side). It becomes an element array that branches off the switches in other sections.

  In the embodiment, the skeleton display routine 30 is started in the final step 213 of the skeleton display data file generation routine 20. However, when the data file generation routine 20 is completed, the skeleton display routine 30 is controlled separately. Alternatively, the skeleton display routine 30 may be activated.
