一种实用的双回线测距方法

ANUSEFUL ALGORITHM FOR FFAULT LOCATION OF PARALLEL TRANSMISSION LINES

提出了一套适用于双回线的故障选相和测距方法，该方法仅仅使用了系统单侧的电压和电流信息，并对这套方法进行了ＥＭＴＰ仿真计算，仿真结果表明，大多数情况下，本方案具有较高的测距精度，同时也证明了本方案的实用价值。

This paper introduces an algrithm for locating the fault points and for selecting faultphases on parallel transmission lines. This algrithm only uses the voltage and current of singleterminal.The EMTP simulation test verifies the high accuracy and applicability of this algrithm.
