摘 要:為了減少系統(tǒng)故障給配電網(wǎng)運行造成的影響,快速準(zhǔn)確地對故障進行定位,對配電網(wǎng)故障定位算法進行了分析,提出了用于輻射狀含有DG配電網(wǎng)故障定位的二進制蜻蜓算法。介紹了蜻蜓算法求解配電網(wǎng)故障定位的具體步驟,并通過算例進行仿真分析說明,該算法能在配電網(wǎng)發(fā)生單點故障、多點故障和伴有部分開關(guān)信息畸變的情況下,均能夠得到準(zhǔn)確結(jié)果。通過與粒子群算法比較,證明了蜻蜓算法在故障定位中的快速性和可靠性。

Abstract: 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.
Key words: distribution network; fault location; dragonfly algorithm; distributed generation
