【摘要】：分布式电源的接入导致传统的故障定位方法不再适用,为了实现配电网快速定位,提出一种基于改进模因算法故障定位算法。首先构建能动态适应分布式电源投切的开关函数,然后以变电站为基础将复杂配电网络分区,划分为相互独立的子网络。将含有多条馈线的子网络划分为几个区域,通过等效原则,在对某一区域进行故障定位的时候,将其他区域进行等效,这样不仅降低了可行解的维度,使计算的复杂性降低,同时也简化了开关函数的计算。利用蚁群算法产生初始种群,模因算法对配电网进行故障定位,仿真结果表明算法能快速的求解出单点故障和多点故障,在信息缺失和畸变情况下,算法也有良好的容错能力。
[Abstract]:The traditional fault location method is no longer applicable because of the access of distributed power supply. In order to realize the fast location of distribution network, a fault location algorithm based on improved meme algorithm is proposed. Firstly, a switching function which can dynamically adapt to the switching of distributed power supply is constructed. Then the complex distribution network is partitioned into independent subnetworks based on substations, and the subnetworks with multiple feeders are divided into several regions. By the principle of equivalence, the fault location of a certain area is carried out. The equivalent of other regions not only reduces the dimension of feasible solution and reduces the complexity of calculation, but also simplifies the calculation of switching function. The ant colony algorithm is used to generate initial population, and the meme algorithm is used to locate the fault of distribution network. The simulation results show that the algorithm can solve single and multi-point faults quickly, and it also has good fault-tolerant capability in the absence and distortion of information.
