Fault Section Location Approach of Distribution Networks Based on Water Cycle Algorithm
Fast and accurate fault section location is crucial to restoring electric supply of distribution networks and reducing the duration of outage.The access of distributed generation transforms the previous distribution networks with unidirectional power flow into complex active distribution networks,which also brings challenges to fault location.To solve the problem that intelligent algorithms have lower speed of fault location and the limitations of optimization,a fault section location approach of distribution networks based on water cycle algorithm is put forward.The feedback informa-tion from each terminal is depicted.The fault current information is processed according to the logic of the upstream and downstream node information,and identifiable abnormal information is corrected.The water cycle algorithm is used to complete the optimization and figure out the faulted line section.Finally,the tests of different distribution networks veri-fy the superiority of the proposed approach.
