Research on the Line Fault Branch Location Method of 10 kV Village Distributed Network

Conference paper
Part of the Lecture Notes in Electrical Engineering book series (LNEE, volume 138)

Abstract

According to the characteristics of village distributed network, such as the main line power supply, the multiple branches, the tree distribution network is equivalent to multiple-input multiple-output network, and based on the equivalent, a multi-terminal mathematical model is established. Fault branch is determined through the measurment of branch resistance changes from measurable endpoint voltage changes, and the algorithm is implemented. The algorithm is verified by simulation of the Matlab software. The results show that this algorithm can quickly and accurately locate the fault branches, improve operational reliability and reduce power losses.
