基于RCA-BA算法的配电网故障区段定位研究
|
摘要
为提高配电网故障区段定位灵敏度和准确率,快速处理故障,恢复供电。将可逆元胞自动机(RCA)与蝙蝠算法(BA)相结合,将蝙蝠看作元胞形成可逆元胞蝙蝠算法(RCA-BA)。蝙蝠不断地在其邻居和前置状态范围内进行寻优。利用动态惯性系数改进BA算法的速度、位置等变量的更新方式,增强了RCA-BA算法搜索的灵敏度,提高了算法搜索到全局最优解的概率。MATLAB仿真结果表明可逆元胞蝙蝠算法能够迅速准确的定位故障区段,同时受采集信号畸变的影响小。
In order to improve the sensitivity and accuracy of fault location in distribution network,process the fault quickly and restore the power,the reversible cellular automaton(RCA)is combined with the bat algorithm(BA)to treat the bat as a cell-forming reversible cell bat algorithm(RCA-BA).The bat constantly seeks to optimize within its neighbor and predecessor states.At the same time,the speed,location and other variables of the BA algorithm are improved by using the dynamic inertia coefficient to improve the sensitivity of the search of the RCA-BA algorithm and improve the probability of the algorithm to search the global optimal solution.The MATLAB simulation results show that the reversible cell bat algorithm can locate the fault area quickly and accurately,and is less affected by the distortion of the acquired signal.
