摘　　要：针对地区电网中不同的客户类型对电能质量指标的不同要求,提出了考虑客户类型的地区电网电能质量综合评估方法。针对各客户类型分别根据D-S证据理论,确定层次分析法(AHP)判断矩阵的各元素,然后计算出针对各客户类型的电能质量指标权重,再考虑各客户类型在地区电网中的重要程度,确定各客户类型的权重,最后将各客户类型电能质量指标权重由多维向一维归并,得到地区电网的各电能质量指标权重。通过考虑各客户类型得出的地区电网综合评估结果,更能体现评估对象的全面性,从而提高评估结果的准确性与科学性。According to preferences of different types of customers on power quality indexes in actual power grid, this paper proposes a power quality comprehensive evaluation method based on types of customers. This paper determines analytic hierarchy process （AHP） judgment matrix elements based on D-S evidence theory for every customer type, and then figures out the power quality indexes＇ weights of each type. It determines the weight of each type with considering the importance of each type in the regional power grid. Finally get the power quality weights of regional grid by merging power quality indexes＇ weights of all types. The evaluation result is more comprehensive with considering the types of customers in regional grid, and has improved the accuracy and scientificalness of the evaluation result.
