摘要针对传统双端行波测距因严格依赖对端数据和双侧时钟同步而难以跨厂家进行协同测距的不足,本文提出不依赖双侧同步的双端行波协同测距方法。首先分析了输电线路故障行波的波到时序特征,根据同时刻母线上各回出线电流群体比幅比相剔除母线相邻各健全线路末端反射波后,后续行波到达时序依故障的强弱呈现两类模态：强故障模态下,故障行波在故障点与两侧母线构成的两区间独立传播,同侧相邻波头等间隔且两侧对应波到时差之和恒定;弱故障模态下,存在可被观测点检测的故障点透射波,两侧对应波到时序保持恒定。两种模态可根据初始行波到达后短时内两侧后续行波到达时序的配对关系予以辨识,进而分别提出相应的不依赖双侧时钟同步的双端数据驱动式协同分析测距方法。数字仿真与现场实测数据均表明所提方法可靠、有效。

Abstract：It is difficult to implement two-ended fault location method between the travelling wave recorders made by different companies, because of the method's strict reliance on remote data and two ended time synchronization. To solve this problem, coordinated double-ended travelling wave fault location method independent of two side time synchronization is proposed in this paper. The features patterns of faulted surge arrival sequence were analyzed: After eliminating the disturbance caused from sound lines by comparing amplitude and phase in group, the sequence of surge arrival can be divided into two patterns. In fierce faulted pattern, faulted travelling waves approximatively propagate independently in two separated segments composed by each monitored buses and faulted point, which makes the time delay consistent for adjacent surges at same side and the sum of corresponding time delay consistent for surges at separate sides. Refraction surges can be detected in weak faulted pattern, which makes sequence of surge arrival consistent at two terminals. The two faulted modes can be identified through matched sequence of initial and follow-up double-ended surges, and the separated two-ended data-driven based travelling wave fault location collaborative approaches independent of two-ended time synchronization were proposed. The proposed method is proven feasible and effective by both digital simulations and field data record.

Key words： Sequence of surge arrival surge matching ping-pong time synchronization travelling wave fault location dynamic time warping (DTW) data driven
