摘要
行波测距是利用高频故障暂态电流、电压的行波来间接判定故障位置,包括单端行波测距法和双端行波测距法。文章对行波故障测距装置在实际应用过程中可能影响行波法测距精度的一些主要因素进行了讨论,包括雷电波的影响、故障时电压相角的影响、故障类型的影响、故障位置的影响、母线端接线的影响、线路类型的影响等,并提出了相应的解决方案。
Traveling wave based fault location includes single terminal and two terminals traveling wave fault location in which the traveling waves of high-frequency transient voltage and current caused by fault is used to indirectly locate the position where fault occurs. The authors research the main factors which may influence the precision of fault location such as the thunder wave, the voltage phase angle during the fault, fault types, fault positions, the wiring of busbar terminals, types of transmission lines and so on, and propose some relevant solutions.
