A mixture approach for distribution fault location is presented . its mathematic model is based on the fuzzy sets , and it can locate the fault arcs in despite of the uncertainty of the fault information 提出了故障定位的混合算法,以實時監(jiān)控系統(tǒng)的遙信、遙測和錄波的三層數(shù)據(jù)為定位的數(shù)據(jù)來源,應(yīng)用模糊理論建立數(shù)學模型,解決故障信息具有不確定性情況的故障定位。
