摘要

With the increasing demand for power quality in China's power users,in order to reduce the failure of the power distribution network caused by the power failure caused by the power grid failure,it was necessary to ensure that the maintenance personnel can quickly come to the fault location for hardening,and the genetic algorithm was used to analyze the fault location of intelligent distribution network.The design principle of fault location of distribution network was studied,the calculation method of fault information was obtained,the formation process of switching function under single power supply and the fault current setting process based on genetic calculation.And the results of the genetic algorithm were consistent with the hypothesis,which verified the reliability of the fault location based on the genetic calculation of the distribution network.Intelligent distribution network fault location analysis had a crucial role for the national grid security level to provide support and protection.%随着我国电力用户对电力质量需要的日益增长,为了减少因电网故障带来的停电影响,要求快速、准确地定位配电网故障位置,从而确保检修人员能够快速来到故障位置进行抢修,采用遗传算法对智能配电网故障定位进行分析研究,研究了配电网故障定位设计原理、获取故障信息的计算方式、单电源供电条件下开关函数的形成过程以及基于遗传算法的故障电流定位流程,并根据某配电网单电源树形拓扑结构进行试验.研究表明:遗传算法的试验结果与假设相一致,验证了基于遗传算法的配电网的故障定位的可靠性,研究对于推进智能配电网故障定位分析具有至关重要的作用,为国家电网安全层面提供支持和保障.
