Correlation Analysis of the Reclosing Success Rate of Power Grid Based on Disaster Type and Line Information
摘要
Abstract
In order to improve the reclosing success rate of transmission lines due to disasters,which can guarantee the reliability and continuity of power supply,historical fault data is taken to excavate the association rules among disaster types,line information and the reclosing success rate.Apriori algorithm is adopted to search the frequent item sets.Then the support,the confidence and the lift are set to extract the efficient and strong association rules.The results show that the reclosing success rate of transmission lines due to lightning and bird are higher,respectively 93.01％ and 89.04％.And the fault tripping caused by wind and icing are not easy to succeed,whose rate are 93.33％ and 84.72％ respectively.In the transmission lines of different voltage levels,effects of lightning and icing in 500 kV line are the most severe,and the main disasters which caused the failure of transmission line's reclosing in 330 kV line are wind and external damage.The research results can provide guidance to optimize the strategy of transmission line's reclosing.关键词
