摘　　要：针对现有定位方法对配电网终端故障定位时存在定位准确性低、无法确定故障位置的问题,本文引入烟花算法,提出究配电网终端故障自动定位方法。首先,对动作、保护信号数值化处理,构建配电网终端故障模型;然后,利用烟花算法定位和诊断故障位置;最后,设计定时数据采集程序,实现终端故障循环自动检测与定位。实验证明,新定位方法的定位结果与实际一致,具有极高的定位准确性。Aiming at the existing positioning method is used to lo cate the terminal fault of the distribution network,the location accuracy is low and the fault location cannot be determined,this paper introduces the fireworks algorithm to study the automatic positioning method of distribution network terminal fault.Firstly,numerical processing of action and protection signals is carried out to construct the distribution network terminal fault model,then,the fireworks algorithm is used to locate and diagnose the fault location,finally,the timed data acquisition program is designed to realize the terminal fault cyclic automatic detection and localization.The experiment proves that the positioning results of the new positioning method are consistent with the actual situation and have extremely high positioning accuracy.
