| 摘 要： | 提出一种基于GPS在线故障定位法,该方法设计2台零序电流探测器借助无线通信手段,相互发送探测到的零序电流相位信息,并根据理论最终确定故障点的位置。该方法不需要外加信号,直接利用故障时产生的零序电流信号,便可实现快速准确的故障定位。物理实验证明了所述方法的有效性。

| Abstract: | With the continuous development of the economics,the customer demand for reliable power supplies is increasing.An on-line fault location method based on GPS was proposed for the single phase ground fault in the distribution network.First,two sets of zero sequence current detectors send and receive the phase information of zero sequence current with each other.Second,the special fault spot is finally identified based on the phase information of zero sequence current.The method is simple,using the fundamental... |
