基于状态量比较法的配电网自愈控制技术研究

摘要

With the gradual deepening of National Smart Grid strategy deployment,for the traditional heuristic search to the limitations of distribution network fault self recovery is proposed in this paper state of comparative law of self-healing control scheme based on and on the distribution grid for real-time monitoring,fast fault clearing.In this paper,we firstly introduce the key technology of self-healing control theory and distribution network self-healing,and to the amount of state comparison principle to explain,the power system simulation software PSCAD/EMTDC simulation to verify the state comparative method in distribution network self-healing control is feasible,provide a kind of effective method for the realization of distribution network self-healing.%随着智能电网的快速发展,采用传统启发式搜索进行配电网故障自愈的局限性越来越凸显,本文通过状态量比较法进行研究,将该算法引入配电网的自愈控制中,对配电网的参数进行高效监测和管理,提高配电网络的自愈控制能力.本文首先重点介绍了自愈控制的相关理论及配电网自愈的关键技术,并对状态量比较法原理进行阐释,最后通过电力系统仿真软件PSCAD/EMTDC进行仿真,验证了状态量比较法在配电网自愈控制中的可行性,为实现配电网自愈提供了一种有效的方法.
