摘要
为了充分准确地评估纺织行业的电压暂降水平,提出一种考虑区间型指标的综合评估方法。首先,根据各监测数据构建对应的多指标集合;其次,采用层次分析法与改进区间指标相关性赋权法(CRITIC)确定各指标的权重,再根据博弈论思想获取综合权重;接着,定义区间数差值关系,采用非整次秩和比法对各监测点电压暂降水平进行评估并分级;最后,采用8个纺织行业的监测数据进行实例分析,结果表明本文所提方法能够充分合理地评估监测点的电压暂降水平。
For fully and accurately evaluating the voltage sag level in the textile industry,a comprehensive evaluation method considering interval-type indices is proposed.Firstly,a multi-index set is constructed based on the monitoring data.Secondly,the weight of each index is determined by using analytic hierarchy process and improved interval criteria importance though intercrieria correlation(CRITIC)method,and then the comprehensive weight is obtained based on game theory.Next,by defining the interval number difference relation,the non-integer order rank-sum ratio method is used to evaluate and grade the voltage sag level at each monitoring point.Finally,eight sets of monitoring data from the textile industry are used for case analysis,and the results show that the proposed method can evaluate the voltage sag level of each monitoring point reasonably.
