| 摘 要： | 配电网故障定位是电力系统的关键技术。针对配电网故障定位精度易受线路参数影响的问题,文章在分析故障定位原理的基础上,提出了基于双端阻抗法的单电源配电网故障区域定位方法,推导了无分支配电网线路单相接地故障测距方程,为多分支配电网的故障测距提供了基础。MATLAB仿真结果验证了该方法的有效性。

| Abstract: | Fault location of distribution network is one of the key technologies for power system.(Aiming) at the problem of fault location precision of distribution network effected by line parameters,the(paper) put forward a malfunction zone location means of distribution network of single power based on double-end impedance method on the basis of analyzing knowledge foundation for fault location.It also(deduced) the range measurement equation of single-phase grounded fault without branch in line of distri-(bution) network,supplying knowledge foundation for distribution network with multibranch.MATLAB simulation results showed that the method is effective. |
