Comprehensive Evaluation on Power Quality Based on Improved Matter-Element Extension Model With Variable Weight
摘要
Abstract
As for the pricing by electrical energy quality and the decision of rewards and penalties based on the examination at assessment point,Comprehensive evaluation on power quality is one of the principal foundations.A comprehensive power quality evaluation model based on improved matter-element extension model with variable weight,in which the classical domain of matter-element extension model and the maximum membership criterion are improved to remedy its boundedness and defects in the evaluation of power quality,is proposed.Meanwhile,applying variable weight theory the weights of all rating indices are determined to reduce the influence of subjective factors during the power quality evaluation and incarnate the active participation of evaluated objects during the comprehensive evaluation.Taking measured data form busbar of a certain 1 10kV for example,the evaluation result shows that the grade of power quality is qualified but far from being satisfied.Case study shows that the proposed model is effective for comprehensive evaluation of power quality.关键词
