摘要

For the existing fault location methods inherent defects in hybrid networks,this paper presents a new method based on feeder terminal unit distributed can realize effective fault location in hybrid 10 kV distribution network with multiple distributed power.Optimization of fault current signal encoding for feeder terminal unit distributed upload the method for optimization of mixed 10 kV distribution network fitness function,through the iterative operation of genetic algorithm,the location of fault line was obtained.Simulation results demonstrate the effectiveness of this method in fault location of hybrid 10 kV distribution networks with multiple distributed sources.%针对现有故障定位方法在混合型电网中的固有缺陷,提出一种基于分布式馈线终端单元的能够在含有多个分布式电源的混合型10 kV配电网实现有效故障定位的方法.该方法针对分布式馈线终端单元上传的故障电流信号进行优化编码,对混合型10 kV配电网优化适应度函数,通过遗传算法的迭代操作获实现对故障线路的定位.仿真实验验证了该方法在含有多个分布式电源的混合型10 kV配电网的故障定位中的有效性.
