摘要
介绍了基于行波的自闭贯通故障原因辨识研究,对自闭贯通多个设备采集的故障时刻行波提取特征量、建立故障原因数据库,对新生故障进行波形比对,从而对区域内故障进行原因辨识和归类统计,指导跳闸线路及未发生故障线路的运维,减少故障造成的不必要停电时间,实现经济效益。
The research on the cause identification of self-closing through failure based on traveling wave is introduced.Based on the fault time traveling waves collected by multiple devices,the feature quantity is extracted and the fault cause database is established,and the waveforms of the new fault are compared so as to identify and classify the causes of regional faults,guide the operation and maintenance of trip lines and non-fault lines,reduce the unnecessary outage time caused by faults,and achieve economic benefits.
