A fault location method of error correction based on ant colony algorithm for distribution network

Abstract

Current distribution network fault location system has a weak fault tolerance. When the information uploaded by FTU is wrong, the misjudgment will often appear. The ant colony algorithm has strong robustness, and it can solve the combinatorial optimization problems better, like distribution network fault location. This paper proposes a fault location method of error correction based on ant colony algorithm for distribution network. Take Yu Xi 10 kV V loop distribution network as an example for experiments. Experiments show that when the information uploaded by FTU is wrong, the method can accurately determine the fault location. It considerably reduces the outage time and power outage scope, which is advantageous to stable power supply for distribution network.
