In addition, monitoring target system measurement information 201 including a part or all of the system measurement information 101, monitoring target weather case information 203 including a part or all of the weather case information 103, and part or all of the system abnormality case information 104. The monitoring target system abnormality case information 204 including the output information is used. Further, the power system operation support device 10a includes a monitored system measurement information extraction unit 11, a similar weather condition data extraction unit 12a, a weather information feature amount extraction unit 13, a system abnormality case geographical information database 14, and a weather case information feature. The quantity extraction unit 15 and the similar case storage database 16a are used.

  The electric power system is composed of a plurality of transmission and distribution lines, and is composed of a plurality of topologies such as a mesh system and a radial system. For example, in the North American continent, high-voltage power transmission lines are often composed of a mesh system. On the other hand, in Japan, high-voltage power transmission lines are often composed of radial systems. However, a power system is generally configured by a combination of various configurations including a mesh system, a radial system, and other configurations.

  In the power system, various factors such as lightning, strong winds, heavy rain, heavy snowfall, typhoons, tornadoes, artificial factors such as work mistakes in maintenance work, and external factors such as aircraft accidents can cause May be abnormal. Abnormal cases include, for example, power outages that occur in customers due to causes such as wire breaks, ground faults, short circuits, etc. Abnormalities may occur. Therefore, the central command station or control station that controls the electric power system constantly measures the voltage, current, frequency, etc. of the electric power system in order to grasp the state of the electric power system by the system measuring device.

  The system measurement information 101 is, for example, physical information including voltage, current, frequency, etc. of a power system, and information including geographical information and temporal information. Geographical information is information such as latitude, longitude, altitude, etc., or information indicating a relative positional relationship in the power system in terms of topology. The temporal information is information indicating time such as year, month, day, hour, minute, second, or the like, or information indicating a relative time relationship with reference time.

That is. The system abnormality case information 104 is, for example, information collected from the power system by a SCADA device installed at a central command center or a control center. Alternatively, information input from the outside may be used.

  In addition, it is difficult to predict beforehand when the above-mentioned human factors and external factors will occur, but regarding meteorological factors, meteorological agencies and meteorological companies constantly measure, analyze, and forecast weather-related information. Therefore, it is relatively easy to predict weather factors. Here, the weather-related information is, for example, physical information represented by temperature, humidity, wind speed, wind direction, solar radiation amount, precipitation amount, snowfall amount, cloud amount, etc., and includes the above geographical information and temporal information.

And the temporal information are compared with each other to extract the weather-related information under the conditions that geographically and temporally match. It should be noted that geographically and temporally matching not only means that all physical quantities completely match, but also that they approximately match. A feature amount is extracted from the weather-related information and is stored as a weather case information feature amount in the similar case storage database 16 in association with the relevant system abnormality case information 104. By extracting the feature amount of the weather-related information here, it is possible to easily extract the data under the weather conditions similar to the weather information 102. The geographical information extracted by the weather case information feature amount extraction unit 15 is stored in the system abnormality case geographical information database 14.

  Next, when the meteorological information 102 is input, the meteorological information characteristic amount extraction unit 13 extracts the geographical information included in the meteorological information 102, and the geographical information stored in the system abnormality case geographical information database 14 is extracted. By comparing with, the weather related information under the geographically matching condition is extracted. Note that geographically matching not only means that all physical quantities completely match, but also that they substantially match. By extracting meteorological information of conditions that geographically match, it is possible to extract multiple meteorological information of the present or future, and to correctly grasp the current electric power system state and the future electric power system state. It is possible to predict the power consumption, and it is possible to improve the reliability of power system operation.

  Next, in the similar weather condition data extraction unit 12a, the feature amount of the weather related information extracted by the weather information feature amount extraction unit 13 and the feature amount of the plurality of weather related information stored in the similar case storage database 16a, And the geographical information, the monitoring target weather case information 203, and the monitoring target system abnormality case information 204, which are related to the feature amount of similar weather related information, are extracted. It is possible to reduce the amount of weather information 102 to be monitored, which has an effect of facilitating data extraction under similar weather conditions.

  Finally, in the monitored system measurement information extraction unit 11, the geographical information output from the similar weather condition data extraction unit 12a is input, and the geographical information of the system measurement information 101 is compared to measure the monitored system. The information 201 is extracted and output from the power system operation support device 10a. The system measurement information 101 to be monitored can be narrowed down, the work of the power system operator can be supported, and the reliability of the power system operation work can be improved.

  In the present embodiment, the systematic abnormality case geographical information database 14 and the similar case storage database 16a are configured as separate databases for ease of description, but they are a single database having equivalent functions. It may be configured as.
