Based on the travelingwave, double ended approach only deals with the first transient travelingwave reaching the two buses of the fault line.
基于行波的输电线路双端测距算法只用到到达故障线路两侧母线的第一个故障初始行波波头，其可靠性较高。

Because of the current on the shunt reactor, traditional travelingwave differential protection cannot be applied to transmission line with shunt reactor.
由于并联电抗器两侧的电流发生变化，传统的行波差动保护无法应用于带并联电抗器的输电线路。

Travelingwave dispersion in the parallel line is more complex than that in the single line and is an important reason why the fault location error is large for travelingwave method.
