Abstract: In order to overcome the problem of long recovery time in traditional fault recovery methods, a novel hierarchical response recovery method for distribution network fault based on topological analysis is proposed in this paper. This method simplifies the structure of complex distribution network, removes the non-concerned nodes in the connection relationship of distribution network, and uses the search method to analyse the distribution network topology, and traverses the distribution network topology nodes through the breadth-first search algorithm. By establishing the fault judgment matrix to locate the faults, an architecture of hierarchical response fault recovery is designed. Membrane computing algorithm is used to restore the hierarchical fault response of distribution network. The experimental results show that the proposed method takes less than 0.8 s to recover from faults and has a shorter recovery time. The response delay is always less than 0.3 ms, and the response delay is low.

Keywords: topology analysis; distribution network faults; hierarchical response recovery; search method; membrane computing algorithm.
