Hybrid line single-ended traveling wave fault distance measuring method based on fault distance interval

Abstract

本发明公开了一种基于故障距离区间的混联线路单端行波故障测距方法,利用单端工频量初步确定故障距离区间,聚焦行波的研究范围,进而针对性地分析行波规律,实现精确故障定位。该方法测距精度高,对连接点邻域故障不存在测距死区,能正确识别连接点故障或判别故障区段;该方法只利用单端数据,技术上易实现,经济性好,便于装置的安装和推广,实际应用价值较高。
The invention discloses a hybrid line single-ended traveling wave fault distance measuring method based on a fault distance interval. A fault distance interval is preliminarily determined based on single-ended power frequency, the focus is on the scope of research of traveling wave, and the law of traveling wave is analyzed in a targeted mode, thereby realizing accurate fault location. The method is high in distance measuring precision, ranging dead zones do not exist for connection point neighborhood faults, and a connection point fault can be correctly identified or a fault section can be correctly distinguished. The method only uses single-ended data, is easy to implement technologically, has high economical efficiency, is convenient for device installation and popularization, and has high practical application value.
