Abstract

One of a plurality of switches constituting a power system is set as a perceived switch, and n optional switches Bk (k=1 to n) in the on state among the other switches are changed to the off state, and n loop networks including the perceived switch are created, and each switch Ck (k=1 to n) constituting the loop networks is changed from the off state to the on state so as to create a plurality of network configuration candidates, and a power network configuration is decided on the basis of the plurality of network configuration candidates.

Description

technical field [0001] The present invention relates to a method and equipment for establishing a power system network configuration, and more specifically, relates to a technique for determining the connection status of a power transmission and transformation facility system in a power distribution or transmission system. Background technique [0002] As a method of establishing a power system configuration, "power distribution system utilizing a genetic algorithm" as described in Journal of Institute of Electrical Engineers of Japan Vol. C116, No. 5 is considered Configuration Optimization Method" (PP.591 to598), for the limitation of feeder capacity, it is proposed to use native algorithm to determine the network configuration. According to this method, in order to maintain the radial network, the genetic structure of the native algorithm is made appropriate, and when setting a closed loop system or a distribution system due to exchange or replacement, preventive measures...
