FIG. 1 is an explanatory diagram for explaining the configuration of a substation monitoring and control system according to Embodiment 1 of the present invention. FIG. 2 is a block diagram showing the configuration of a central monitoring and control device of the substation monitoring and control system. 3 is a block diagram showing the configuration of the monitoring terminal device and the equipment abnormality detection unit of the substation monitoring control system, FIG. 4 is a diagram showing an example of the storage contents of the storage unit of the central monitoring control device, FIG. 5 and FIG. 6 is an explanatory diagram for explaining the configuration of the substation according to the substation monitoring and control system, FIG. 7 is a perspective view showing the configuration of the disconnector of the substation, and FIG. 8 is the configuration of the disconnector. FIG. 9 to FIG. 11 are process procedure diagrams for explaining the operation of the central monitoring and control apparatus.

  As shown in FIG. 1, the substation monitoring and control system 1 includes a central monitoring and control device 2 provided at a control station A and monitoring terminal devices 3a, 3b,... Disposed at substations B1, B2,. Can be connected via the network 4, and further, as shown in FIG. 3, equipment abnormality detectors 13a, 13b,... Are arranged for each electrical facility in each substation B1 (B2, B3,...). It is roughly structured.

  As shown in FIG. 2, the central monitoring control device 2 includes a central processing unit 6 that controls each component according to a predetermined control program, a storage unit 7 that stores various control programs and data, and data communication according to a predetermined protocol. A communication unit 8, a display unit 9, and an operation unit 11.

  The central processing unit 6 includes a CPU (Central Processing Unit) and the like, and controls each component in accordance with a predetermined control program stored in the storage unit 7. The central processing unit 6 executes, for example, a constant monitoring process and an accident process according to the control program stored in the storage unit 7. The constant monitoring process includes an image information acquisition process, a temperature information acquisition process, a three-dimensional image information generation process, an image abnormality monitoring area temporary identification process, a temperature abnormality monitoring area temporary identification process, an abnormality monitoring area identification process, It includes operation device specifying processing and device operation command processing.

  The central processing unit 6 acquires the image information and the temperature information from the monitoring terminal devices 3a, 3b,... In the image information acquisition process and the temperature information acquisition process, and stores them in the storage unit 7. In addition, the central processing unit 6 generates 3D image information based on the acquired image information in the 3D image information generation processing, stores the 3D image information in the storage unit 7, and displays the 2D information on the display unit 9. Let

  Further, the central processing unit 6 compares the three-dimensional image information at a predetermined time interval (for example, approximately 1 minute) in the temporary image abnormality monitoring region specific processing, and compares it with the three-dimensional image information before this predetermined time, When the current three-dimensional image information differs by a predetermined ratio (for example, 10% in area ratio) or more, it is determined as abnormal. Here, the central processing unit 6 tentatively specifies a monitoring area where an abnormality has occurred by dividing an image of the electrical facility into a plurality of monitoring areas. For example, as shown in FIG. 7, a disconnector (241 A LS) 241LSa as an electrical facility is connected to a monitoring area Ma on the side of the bus line from the symmetry line connecting the axes of the insulators 29a, 29b, and 29c, and The monitoring area Mb is divided into two, and the monitoring areas Ma and Mb are respectively determined whether there is an abnormality.

  Further, the central processing unit 6 compares temperature information at a predetermined time interval (for example, approximately 1 minute) in the temperature abnormality monitoring region temporary specific processing, and the current temperature is compared with the temperature before this predetermined time. It is determined that there is an abnormality when it differs by more than a predetermined rate of increase. Here, as in the case of the image abnormality monitoring area temporary specifying process, the central processing unit 6 temporarily specifies the monitoring area where the abnormality has occurred.

  In addition, the central processing unit 6 identifies the monitoring area where the abnormality has occurred in the abnormality monitoring area specifying process based on the identification results in the image abnormality monitoring area temporary specifying process and the temperature abnormality monitoring area temporary specifying process. For example, when the two monitoring areas do not match, not only the overlapping area but also the area including both monitoring areas is specified as the monitoring area where the abnormality has occurred.

  Further, the central processing unit 6 searches the monitoring control information database 7a of the storage unit 7 in the operating device specifying process, and specifies the “off” operation target device corresponding to the specified monitoring area. For example, as shown in FIG. 6, when an abnormality occurs in the accident range G, and the monitoring area on the A and B aperture side of the disconnector (241 A LS) 241LSa of the A substation is specified as the abnormality monitoring area, The breaker 241CB and the disconnector 241LSa are specified as “off” operation target devices. When the monitoring area on the side of the busbar of the disconnector (241 LS) 241LSa is specified as the abnormality monitoring area, the circuit breakers 241CB, 232CB, 243CB, and 257CB are specified as “off” operation target devices.

  In addition, the central processing unit 6 sends a command signal for operating the specified operation target device to the monitoring terminal device 3a (3b, 3c,...) Via the communication unit 8 in the device operation command processing. For example, if the monitoring area on the A and B aperture side of the disconnector (241 A LS) 241LSa of the A substation is specified as the abnormality monitoring area, the disconnector 241LSa is operated to be “off” after the interrupter 241CB is disconnected. Command signal is sent out.

  The accident process includes an image abnormality monitoring area temporary identification process, a temperature abnormality monitoring area temporary identification process, an abnormality monitoring area identification process, an operating device identification process, and an equipment operation command process. The central processing unit 6 compares the three-dimensional image information before the accident with the three-dimensional image information after the accident in the image abnormality monitoring area temporary specifying process, and, for example, by a predetermined ratio due to equipment breakage, foreign object contact, etc. When the difference is more than (for example, 10% in area ratio), it is determined as abnormal. Here, the central processing unit 6 tentatively specifies a monitoring area where an abnormality has occurred by dividing an image of the electrical facility into a plurality of monitoring areas. For example, information stored in the storage unit 7 is used as the image information (three-dimensional image information).

  The central processing unit 6 compares the temperature before the accident with the temperature after the accident in the temperature abnormality monitoring area provisional specific process, and if the current temperature changes at a rate of increase of a predetermined rate or more, Judgment is made, and a monitoring area where an abnormality has occurred is tentatively specified. For example, information stored in the storage unit 7 is used as the temperature information.

  In addition, the central processing unit 6 performs the abnormality monitoring area specifying process based on the identification results in the image abnormality monitoring area temporary specifying process and the temperature abnormality monitoring area temporary specifying process, and the protection range information of the operated protective relay. Specify the monitoring area where the error occurred. For example, when the two monitoring areas do not match, not only the overlapping area but also the area including both monitoring areas is specified as the monitoring area where the abnormality has occurred. The central processing unit 6 performs the same processing as the operation device identification processing and device operation command processing in the constant monitoring processing in the operation device identification processing and device operation command processing.

  The storage unit 7 includes a ROM, a RAM, an FD (flexible disk), an HD (hard disk), an FDD on which a CD-ROM is mounted, an HDD, a CD-ROM driver, and the like. The storage unit 7 includes a program storage unit that stores various programs and an information storage unit that stores various types of information such as setting information. As shown in FIG. 4, the information storage unit has a monitoring control information database 7a. In the monitoring control information database 7a, “off” operation target devices when an abnormality is detected are stored for each monitoring area in association with the substation and the electrical equipment.

For example, as shown in FIGS. 5 and 8, the 3D cameras 18 a and 18 b are arranged on a diagonal line in a rectangular region in plan view, and each of the buses of, for example, a disconnector (241 A LS) 241 LSa as electrical equipment The side and the aperture stop side are imaged. The thermocameras 19a and 19b are disposed at substantially the same positions as the 3D cameras 18a and 18b, for example. For example, the 3D cameras 18a and 18b are supported by stretchable rod-like insulating support members 22a and 22b, respectively. For example, at the time of inspection, the 3D cameras 18a and 18b can be removed or retracted.

Further, the transformer Tr1 ( Tr2) is connected to a connection point of a predetermined pair of disconnectors connected to the 66 kV bus via a circuit breaker 233CB (232CB). In the 110 kV bus, a transmission line A No. 1 (A Line 2, B Line) is connected to a connection point between a predetermined pair of disconnectors via a circuit breaker 205CB (206CB, 203CB, 204CB, 201CB, 202CB, 211CB, 212CB). No. 1, B line 2, C line 1, C line 2, D line 1, D line 2) are connected. In the 66 kV bus, the E-line 1 (E-line 2, F-line 1, F-line) is connected to the connection point of a predetermined pair of disconnectors via the circuit breakers 241CB (242CB, 243CB, 244CB, 257CB, 258CB). Line No. 2, G Line No. 1, G Line No. 2) are connected. For example, the circuit breaker 241CB is connected to the connection point between the disconnector on the busbar side (241 A LS) 241LSa and the disconnector on the busbar side (241B LS) 241LSb. Note that the 110 kV bus (66 kV bus) A bus and the Oto bus are also connected through the circuit breaker 200CB (250CB).

  Next, the operation of the substation equipment monitoring control system will be described with reference to FIGS. First, in the central monitoring controller 2, the central processing unit 6 performs a constant monitoring process (step SA11 (FIG. 9)). Next, in step SA12, it is determined whether or not the protective relay has been operated. If so, the process proceeds to step SA13, and if not, the process proceeds to step SA14. In step SA13, an accident process is executed. In step SA14, for example, it is determined whether or not an end operation has been performed. If the end operation has been performed, the process ends. Otherwise, the process returns to step SA11.

  Next, the constant monitoring process will be described. First, the central processing unit 6 acquires image information (step SB11 (FIG. 10)), and acquires temperature information (step SB12). Next, in step SB13, it is determined whether there is an image abnormality. If the image is abnormal, the process proceeds to step SB14; otherwise, the process proceeds to step SB15. In step SB14, the monitoring area where the image abnormality is detected is provisionally specified. In step SB15, it is determined whether or not the temperature is abnormal. If the temperature is abnormal, the process proceeds to step SB16. Otherwise, the process proceeds to step SB17. In step SB16, the monitoring area where the temperature abnormality is detected is provisionally specified. In step SB17, it is determined whether the image is abnormal. If the image is abnormal, the process proceeds to step SB18. Otherwise, the process returns to the main routine (step SA12). In step SB18, the monitoring region where the abnormality is detected is specified based on the monitoring region where the image abnormality or the temperature abnormality is detected. Next, in step SB19, it is determined whether or not there is a power failure. If there is no power failure, the process proceeds to step SB20. If there is a power failure, the process proceeds to step SB21. In step SB20, an “OFF” operation command for the corresponding device is sent, and an alarm is output at the same time.
