    Abstract:

    The effective evaluation of the characteristics of power supply for low voltage distribution network is the basis and basis for the development of power supply enterprises and the decision making of low-voltage distribution network.In this paper,we put forward a kind of based on improved principal component analysis of low voltage distribution network power substation comprehensive evaluation method,combining with the advantages of traditional principal component analysis and analytic hierarchy process,established index evaluation system,and can reflect 132 power supply in economic efficiency,power supply reliability and the superiority of coordination on the adaptive nature of the three scores.Recycling system clustering method to score,to explore the different power supply in different characteristics on the development of the status quo,combined with the data from 2015,2016 two years longitudinal comparison,through the example analysis and calculation,based on improved principal component analysis of the comprehensive evaluation method of low voltage distribution network evaluation and subsequent development of power substation is practical and effective.
