いる。In this way, the future power system connection form 1. In other words, by comparing the target system with the current power system connection form, that is, the current system, circuit breakers with different opening and closing states are extracted as operation candidate circuit breakers, and then from among the operation candidate circuit breakers, The circuit breakers to be operated are selected based on priority and restoration operations are performed in sequence.

に復旧できないという問題がある。According to the conventional recovery operation method, if there are multiple operable circuit breakers for the "close operation for charging" in the priority order (■), there is no standard for which circuit breaker to select, and the circuit breaker is selected at random. A switch is selected. Therefore, there is a problem in that it is not always possible to recover from highly important areas.

By closing the circuit with the highest priority, the most important areas with large current values will be restored.

P>0) β=1 (P≦0), and the constants α and β are set to the same value, but when transmitting power to the load by increasing the constant α, and when increasing the constant β, It is now possible to raise the priority of each restoration operation to secure power generation, and to adjust dynamics according to the system status.
By changing the values of constants α and β, it is possible to give priority to operations suitable for the system status.

Although we used the power flow value for each line and each transformer, it is possible to use the power flow value for all lines with the same line name as the power flow value P, or the power flow value for all transformers in the same electric station as the power flow value P. Even if there are variations in the number of lines or the number of transformers constituting a line with the same line name, it is possible to give priority to circuit closing operations in consideration of the importance of lines with the same line name.

Since the system closes the circuit, it has the excellent effect of always being able to reliably restore the most important areas.
