为了减少系统故障给配电网运行造成的影响,快速准确地对故障进行定位,对配电网故障定位算法进行了分析,提出了用于辐射状含有DG配电网故障定位的二进制蜻蜓算法。介绍了蜻蜓算法求解配电网故障定位的具体步骤,并通过算例进行仿真分析说明,该算法能在配电网发生单点故障、多点故障和伴有部分开关信息畸变的情况下,均能够得到准确结果。通过与粒子群算法比较,证明了蜻蜓算法在故障定位中的快速性和可靠性。

To reduce the influence of system faults on the operation of distribution network,to locate the faults quickly and accurately and to carry out analysis to the distribution network faults location algorithm,this paper proposed the binary dragonfly algorithm of distribution network radial faults location with DG.Introduction was made to the specific steps which were used to solve the distribution network faults location with the dragonfly algorithm.The simulation analysis of examples shows that the algorithm can get accurate results in the case of single point faults,multi-point faults and partial switch information distortion.Compared with the particle swarm optimization,the dragonfly algorithm is proved to be fast and reliable in faults location.
