摘要
Abstract
Based on adaptive cumulative sum(ACUSUM)algorithm,an adaptive reclosure method is proposed in this paper to distinguish the fault property and detect the secondary arc extinction time. Firstly,the varying characteristics of fault phase voltage amplitude in different fault conditions are studied,and the basic principles for fault recognition and the location of secondary arc extinction time are proposed by detecting the increase and decrease of voltage ampli?tude. Secondly,ACUSUM algorithm is modified to overcome the disadvantages of large computation load and short dura?tion of trigger signal. At last,an implementation schema for adaptive reclosure is given. The feasibility and effectiveness of the proposed schema is verified through simulations. This method is easy to realize with strong anti-interference abili?ty,and it is suitable for the transmission lines with and without shunt reactors.关键词
