【摘要】 目前普遍采用故障电流分析方法进行配电网的故障定位和隔离计算 ,在实际应用中对于故障信息的畸变有可能误判或错判。针对这一点 ,改用分级式判别法对故障信息进行判断 ,利用遗传算法的高容错性能 ,进行全局寻优求解。分级处理后可以扩大故障判断的适用范围 ,增强容错性 ,提高准确率。仿真结果证明该方法适用性好更多还原

【Abstract】 Aimed at possible error existed in fault current analysis because of fault signal distortion, it is submitted that the fault signal is determined in steps in fault location and isolation. It uses fault current analysis method firstly,then fuzzy GA method. The simulation results show that the method owns good applicability.更多还原
