智能配电网的故障自愈技术研究

Research on Technologies of Self healing Control on Smart Distribution Network

为解决配电网严重滞后的问题,减少电力系统大面积级联事故的发生,进一步加快电网建设,优化配电网的结构模式,电力系统将"自愈"这一概念引入到智能配电网中.主要研究含分布式电源的配电网自愈控制技术,研究分析故障自愈技术如何消除分布式电源并网后对线路的网络损耗及节点电压等参数的影响.通过借助蚁群算法的分析模式,进一步降低网络损耗,平衡电路负荷,提高电压水平.

In order to solve the serious lag issues of our country distribution network,to reduce the incidence of large cascading accidents of grid,to speed up construction of power grids,to optimize network structure and built a strong distribution network,People will biosphere’s “self-healing” concept introduced to the power system,but also Self-healing is one of notable difference of a smart distribution network and the traditional grid.The self-healing control technology of distribution network with distributed generation technology is discussed in this paper.Therefore,Algorithm-ant colony optimization with the help of a simulated ant foraging behavior algorithms,in order to reduce network losses and improve voltage level and balance the load,restore the power supply.
