基于AMSFLA的配电网故障定位研究

Research on fault location using adaptive mutation shuffled frog leaping algorithm in distribution network

随着电网的不断发展,其网络架构趋于复杂,电网线路发生故障的概率也随之增加,目前配电网故障指示器作为对线路故障检测的主要工具,仍然具有故障识别率低、易发生误动的缺点。为了解决故障指示器目前存在的问题,针对其现状进行分析,构建了配电网故障定位模型,提出一种基于AMSFLA(自适应变异混合蛙跳算法)的故障指示器定位方法,并结合IEEE33节点配电网模型来进行仿真验证。结果表明,该算法能够在故障信号畸变的情况下准确定位故障区域,为运维工作人员故障排查提供帮助。

With developing of power grid,the network structure becomes more complex and the fault probability increases,the fault indicator becomes useful tool in distribution network,but the fault recognition rate is still low. In order to solve the problems existing in the fault indicator,this paper constructed a fault location model in distribution network by analyzing of fault indicator,and presented a fault indicator positioning method based on adaptive mutation shuffled frog leaping algorithm. Using the simulation of IEEE33 node distribution network model,the results show that the algorithm can accurate fault location area when sampled signal is distortion. So the algorithm can provide help for the operation and maintenance work.
