Aiming at the problem that typhoon disaster can easily cause distribution lines to fail, thus affecting the safe and reliable operation level of distribution network, an identification method of vulnerable lines in distribution network under typhoon disaster is proposed. Firstly, considering the local and global network topology, power flow distribution, equipment parameters, external environment and fault loss, four multi-angle evaluation indexes of line vulnerability are put forward from the structural level and equipment level of distribution network. Then, normalizing the index data. Finally, a comprehensive evaluation index is obtained through the analytic hierarchy process and the entropy method, and a multi-angle identification system for vulnerable lines of the distribution network under typhoon disasters is constructed. The simulation results of IEEE RBTS BUS6 F4 feeder system show that the normalized values of degree, intermediate number, failure rate, loss degree and comprehensive vulnerability of the 10th vulnerable line in the system are 0.4733, 0.0860, 0.7970, 0.4207 and 0.4889 respectively. The index values of the top 10 lines are larger than the above values, and their vulnerability is relatively high; The index values of the lines ranked after 10th are smaller than the above values, and their vulnerability is relatively low. The line with high vulnerability is characterized by being located in the upstream position, trunk line, branch or long length of distribution network.
