针对目前县域配电网综合评价方法中存在的不足,提出了基于主成分分析法与对应分析法的县域配电网整体状况分析方法,从安全性、经济性、可靠性、适应性和优质性5个方面选取相关指标建立配电网综合评价指标体系,2次运用主成分分析法,计算各个性质的权重以及各县域配电网的综合得分并对其进行分类.最后,将配电网综合得分与5个一级指标的得分,以及配电网综合得分与5个一级指标各主成分的得分分别绘制成图,通过比对5个一级指标及其各主成分可清晰准确地确定各个县域配电网状况的优劣情况,进而确定各个县域配电网的薄弱所在与发展路径.此外,首次将对应分析法引入配电网整体状况与核心经济指标间对应关系的分析中,为制定配电网发展规划提供经济性依据.%Aiming at the insufficiencies of county power network comprehensive evaluation method,county power network overall situation analysis method is proposed based on principal component analysis(PCA)and corresponding analysis.Distribution network comprehensive evaluation index system is established from five aspects of safety,economy,reliability,adaptability and high quality.PCA has been used twice to calculate the weight of each nature as well as the county comprehensive score,and carry on the classification of distribution network.Finally,the distribution network comprehensive score and the score of five level-1 index,as well as the principle component score of distribution network and five level-1 index are respectively plotted.The advantages and disadvantages of each county distribution network can be determined clearly and accurately by comparing five level-1 indexes and their principal components,then determine the weak location and development path of each county distribution network.In addition,the correspondence analysis method is firstly introduced into the analysis of corresponding relationship between the overall situation of distribution network and the core economic indexes.It provides economic basis for the development planning of distribution network.
