密切值法在电能质量综合评价中的应用

Application of intimate data method in synthetical evaluation about power quality

密切值法作为一种多目标的决策方法适用于多测点、多指标的评价系统。从电能质量的多种评价指标着手,将密切值法用于电能质量的综合评价中。该方法具有原理简单、概念清晰、易于实现等特点,同时不需要确定隶属函数等主观性参数,使评价结果更具客观性,实例计算结果表明该方法是有效的,可供电力系统电能质量问题的分析、评价参考。

The intimate data method, which is one of multi-goal decisions-making methods, is suitable for the multi-measuring points and the multi-targets appraisal system. This paper focuses on multiple evaluation indexes of power quality and introduces intimate data method into synthetic valuation of power quality. This method, which has simple principle, clear conception and high feasibility, can make the valuation result more objective without determining the subjective parameters such as membership function. The testing results came from practical cases verifies the effectivity of this method for electricity quality analysis and assessment in power system.
