对电能质量各项指标进行综合评估，可量化现有各层面电能质量状况，便于实现电力市场的按质定价。利用改进的层次分析法和主成分分析法确定各指标的组合权重，同时将改进的逼近理想解排序（TOPSIS）法与秩和比（RSR）法应用于电能质量综合评估，将观测点电能质量状况与理想解、国标允许值和自设的等级值结合到一起进行排序和分档，从而快速实现电能质量综合评估。实例计算结果表明，采用上述方法具有一定的有效性和可行性。
對電能質量各項指標進行綜閤評估，可量化現有各層麵電能質量狀況，便于實現電力市場的按質定價。利用改進的層次分析法和主成分分析法確定各指標的組閤權重，同時將改進的逼近理想解排序（TOPSIS）法與秩和比（RSR）法應用于電能質量綜閤評估，將觀測點電能質量狀況與理想解、國標允許值和自設的等級值結閤到一起進行排序和分檔，從而快速實現電能質量綜閤評估。實例計算結果錶明，採用上述方法具有一定的有效性和可行性。

The quantized result from synthetic evaluation of power quality is one of the foundations to assess power quality and is favorable to implement the market mechanism of pricing electric ener-gy according to power quality. This paper uses the improved AHP and the principal component analysis (PCA) to determine the index of the combination weights;meanwhile, the improved TOPSIS and rank sum ratio(RSR) method is applied to the comprehensive assessment of the power quality, so the observation point of the power quality and the ideal value, standard value and rank values set up can be sorted and classified together, and power quality comprehensive evaluation can be achieved quickly. Calculation results of case study show that the proposed synthetical evaluation method is effective and feasible.
