摘要：
A multi-source situation awareness framework and a weakness identification method for distribution network considering ice disaster are proposed in this paper. Based on analysis of multi-source information from geographic system, meteorological system, power system and social resources, this paper proposed an integrated situation awareness framework including line segments real-time risk, power supply equipment risk, defense risk, disaster failure and network topology, and overcame the limitation of predicting fault probability only through line icing. Theice modelof distribution line was modifiedand aline segment comprehensive vulnerability index (LSCVI) was established to measure the degree of weakness and improve the identification ability of weakness. Finally, correctness and effectiveness of the proposed method were verified through case study of a large city in Northeast China. It is of great significance for timeliness and accuracy of distribution network active defense toward ice disaster. © 2019, Power System Technology Press. All right reserved.
