传统的单端交流电压和电流故障测距方法不适用于多端系统。提出了一种新的多端双回线故障测距算法。该方法使用每个端子处的差分电流的大小，并且还使用基于3端子故障定位算法和从n端子到3端子系统的等效转换的算法。对于在同一地点和同一时间发生在两条线路上的多故障以及单故障，新算法是相当准确的。给出了EMTP仿真结果。<<ETX>>
Conventional fault location methods using one-terminal AC voltage and current are not applicable to multi-terminal systems. A new fault location algorithm for multi-terminal two parallel transmission lines is described. This method uses the magnitude of the differential currents at each terminal and also uses an algorithm based on a 3-terminal fault location algorithm and an equivalent conversion from an n-terminal to a 3-terminal system. For a multi-fault occurring at the same place and same time on both lines as well as a single-fault this new algorithm is reasonably accurate. EMTP simulation results are shown.<<ETX>>
