摘　　要：为了提高电能质量综合评估的客观性、科学性,该文将几种典型的主观赋权法和客观赋权法相组合建立优化模型,通过求解优化模型来确定电能质量综合评估各指标最终的权重值。该方法克服了单一赋权法的缺点,使得权重的确定更为合理。分析计算表明,利用组合赋权法确定权重值后再对电能质量进行综合评估,比利用任何一种单一赋权法确定权重后再进行综合评估,评估的结果更加客观、完善,更符合实际。In order to improve the objectivity and scientific of the power quality comprehensive evaluation, this paper combines several kinds of typical subjective weighting method and objective weighting method and establishes the optimization model. By solving the optimization model to determine the weight value of each index of power quality comprehensive evaluation. The method overcomes the shortcomings of the single weighting method and makes sure the weight more reasonable. Analysis shows that using combinatorial weighting method to determine the weight and evaluating the power quality make the evaluation result more objective, perfect and practical.
