基于分布式行波检测的配电网单相接地故障定位方法
A single-phase-ground fault location method for distribution networks based on distributed traveling wave detection
摘要
Abstract
To solve the problem of precise location for long-standing single-phase ground fault in complex tree-type distribution network , the paper studies transmission characteristics of traveling wave modulus , and presents a new fault location method combining the two traveling wave principles .First, the multi-terminal location algorithm is established to find out fault trunk line and narrow fault location scope .Second , a double-terminal fault location algorithm based on the time gap between zero mode and aerial mode traveling is put forward to calculate the fault distance .Finally , according to the information of multi-terminal and double-terminal fault location , the fault point is determined .The simulation indicates that the location method can carry out accurate fault location with traveling wave location device mounted on only part of the ends in distribution network .Therefore , it can save investment effectively , and has ad-vantages of little data load and simple algorithm implementation .关键词
