[Figure 9] This is an explanatory diagram illustrating the hardware configuration of each device according to the said embodiment. [Modes for carrying out the invention]

[0014] Embodiments of this disclosure will be described below with reference to the drawings. Figure 1 is a schematic block diagram showing an outline of a power system monitoring and control system 10 according to one embodiment of this disclosure. The power system monitoring and control system 10 (system monitoring and control system) is communicated via communication lines to a plurality of power plants, substations, switching stations, etc., which constitute the power system. The power system monitoring and control system 10 monitors the status of electrical equipment (e.g., transformers, switches, generators, disconnectors, busbars, etc.) installed in each power plant 20 via the communication lines and controls this electrical equipment. The power system monitoring and control system 10 is implemented by one or more computers reading and executing a program.

[0015] Figure 2 is a schematic block diagram showing the configuration of the power system monitoring and control system 10 in this embodiment. Figure 2 shows only the parts of the power system monitoring and control system 10 that are relevant to this disclosure, and the power system monitoring and control system 10 may have other components. As shown in Figure 2, the power system monitoring and control system 10 includes a storage unit 11, a display unit 12, and a search unit 13.

[0016] The storage unit 11 stores information regarding a plurality of electrical substations 20. Further, the storage unit 11 stores, as information regarding the electrical equipment installed in each of the plurality of electrical substations 20, information including the equipment identification string of each of the plurality of electrical equipment, in association with the electrical substation 20 in which the electrical equipment is installed. For example, the information regarding the plurality of electrical substations 20 may be stored in one file (electrical substation file), and the information regarding the electrical equipment may be stored in a file (equipment file) for each electrical substation 20. Note that the storage unit 11 is configured by a non-volatile memory such as a hard disk device, an SSD (Solid State Drive) device, a magneto-optical disk device, a flash memory, a storage medium that can only be read such as a CR-ROM, a volatile memory such as a RAM (Random Access Memory), or a combination thereof.

[0017] The display unit 12 causes a display means (not shown in FIG. 2) to display a system diagram of a power system including a plurality of electrical substations 20. The display means may be a display such as a liquid crystal display or an organic EL (Electro-Luminescence) display included in the power system monitoring and control system 10. Further, the display unit 12 displays a region (search box) for inputting a search target string together with the system diagram. The input of the search target string may be performed by an operator of the power system monitoring and control system 10 using input means such as a keyboard or a mouse.

[0018] When the search target string input in the region is an equipment identification string for identifying electrical equipment or a part of the equipment identification string, the display unit 12 changes the display mode of the electrical substation 20 in which the electrical equipment identified by the equipment identification string is installed, among the plurality of electrical substations 20 in the system diagram, to a first display mode. The equipment identification string is, for example, an electrical equipment name or an identification number of the electrical equipment. Note that the equipment identification string may be other information regarding the electrical equipment such as the type of the generator. Further, the first display mode is, for example, a green highlight display.

[0019] In addition, when the display unit 12 causes the display means to display a detailed diagram including a plurality of electrical facilities installed in the electrical station 20 specified by the operator from the system diagram using an input means such as a mouse, etc., in the same manner as the system diagram. When the one electrical station 20 is the electrical station 20 in which the electrical facility identified by the facility identification character string is installed, the display unit 12 sets the display mode of the electrical facility identified by the facility identification character string in the detailed diagram to a second display mode (for example, yellow highlight display) different from the first display mode.

[0020] Also, when the search target character string is an electrical station identification character string that identifies the electrical station 20 or a part of the electrical station identification character string, the display unit 12 changes the display mode of the electrical station 20 identified by the electrical station identification character string among the plurality of electrical stations 20 in the system diagram to the second display mode described above. Thus, the display unit 12 sets the electrical facility or electrical station 20 directly searched by the search target character string to the second display mode, and sets the electrical station 20 in which the searched electrical facility is installed to the first display mode. For this reason, when the display mode of the electrical station 20 becomes the first display mode, the operator of the power grid monitoring and control system 10 designates the electrical station 20 to display the detailed diagram. By performing such an operation, the operator remembers the electrical station 20 in which the searched electrical facility is installed and can thereafter operate without relying on search. In particular, when the operator is a newly assigned person or a person assigned from another place, by performing such an operation, the operator can operate without relying on search without receiving guidance from an experienced operator.

[0021] The search unit 13 searches the information stored in the storage unit 11 for the string to be searched, which is entered in the area for entering the string to be searched. As a result, if the string to be searched is an equipment identification string or part thereof, the search unit 13 identifies the electrical equipment identified by the equipment identification string, and further identifies the power station 20 where the electrical equipment is installed, which was associated with the information containing the equipment identification string. If the string to be searched is a power station identification string or part thereof, the search unit 13 identifies the electrical equipment identified by the power station identification string. Note that the electrical equipment and power stations identified by the search unit 13 may be multiple, or may include both electrical equipment and power stations. In that case, the display unit 12 may display multiple electrical equipment, multiple power stations, or both electrical equipment and power stations as either the first or second display mode.

[0022] Figure 3 is a table showing an example of the contents of the substation file stored by the storage unit 11 in this embodiment. In the example shown in Figure 3, the substation file stores information about substation 20, associating the substation number "N1", the substation name "XX Substation", the equipment number "NN1", and so on. Similarly, the substation file stores information about substation 20, associating the substation number "N1", the substation name "XX Substation", the equipment number "NN2", and so on. Furthermore, the substation file stores information about substation 20, associating the substation number "N2", the substation name "XX Substation", the equipment number "NN2", and so on. The substation number and substation name are examples of substation identification strings. The equipment number is a number that identifies the electrical equipment installed in the corresponding substation 20, and is part of the information about the electrical equipment.

[0023] Figure 4 is a table showing an example of the contents of an equipment file stored by the storage unit 11 in this embodiment. Figure 4 shows an example of information about electrical equipment stored in one of the equipment files. In this example, the equipment file stores information about electrical equipment, associating the equipment number "NN1", the equipment name "AA switch", and ... Similarly, the equipment file stores the equipment number "NN2", the equipment name "AB transformer", and ... The equipment number and equipment name are examples of equipment identification strings. Note that the equipment file may also contain information indicating which substation 20 the equipment file belongs to (substation name, substation number, etc.). In addition, if the electrical equipment is a generator, the equipment file may also contain information indicating the type of generator (pumped-storage hydroelectric power, thermal power, etc.).

[0024] Figure 5 is a flowchart illustrating an example of the operation of the search unit 13 and the display unit 12 in this embodiment. When the search button is clicked, the search function process of the search unit 13 is started (step Sb1). Once started, the search function process opens the management files (electric station file, equipment file) of equipment information stored in the storage unit 11 (step Sb2). Next, the search function process searches for the name (string to be searched) entered in the search box in the management file opened in step Sb2 (step Sb3). Next, the search function process saves the equipment information found through the search in step Sb3 (step Sb4). This equipment information includes the electric station name if it is found through the search, and the equipment name and the name of the electric station where the electrical equipment of that equipment name is installed if it is found through the search. The search function process sends an event to the screen display process of the display unit 12 with the equipment information found through the search. If no equipment information is found through the search, the search function process terminates (step Sb5).

[0025] The screen display process of the display unit 12 is activated by an event transmission from the search function process (step Sb6). When activated, the screen display process highlights the equipment information transmitted by the event and updates the system diagram screen (step Sb7). At this time, if the equipment information includes only the name of the power station, the power station name may be highlighted in yellow (second display mode), and if the equipment information includes both the power station name and the equipment name, the power station name may be highlighted in green (first display mode). If the display transitions within the system diagram screen which includes a detailed diagram, the screen display process repeats the operation of step Sb7, and if the display transitions to a screen other than the system diagram screen, the screen display process terminates the highlighting of the equipment information (step Sb8). If the detailed diagram includes the equipment name included in the equipment information, the equipment name may be highlighted in yellow (second display mode).

[0026] Figure 6 is a schematic diagram showing the first display example G1 of the system diagram in this embodiment. The first display example G1 is an example of the system diagram display when a power station name is found in the search results. The search box D1 contains the string "DDD" which is the search target. The shading of the power station name "DDD" for power station E1 indicates that it is highlighted in yellow (second display mode). The yellow highlighting of the power station name indicates that power station 20, which is the power station that was found in the search results, is power station E2.

[0027] Figure 7 is a schematic diagram showing a second display example G2 of the system diagram in this embodiment. The second display example G2 is an example of the system diagram display when an equipment name is found in the search. The search box D2 has the string "FFF" entered as the search target. The shading of the power station name "BBB" for power station E2 indicates that it is highlighted in green (first display mode). The green highlighting of the power station name indicates that the electrical equipment of the equipment name found in the search is installed in power station E2 and is included in the detailed diagram of power station E2.

[0028] Figure 8 is a schematic diagram showing example G3 of the detailed view in this embodiment. Example G3 is an example of the detailed view displayed by step Sb7 in Figure 5. The search box D3 contains the string "FFF" to be searched. The shading of the equipment name "FFF" for electrical equipment F3 indicates that it is highlighted in yellow (second display mode). The yellow highlighting of the equipment name indicates that the electrical equipment whose name was found in the search is electrical equipment F3.
