Comprehensive evaluation method for low-voltage transformer areas of regional intelligent distribution network

Abstract

The invention relates to the field of evaluation on a regional intelligent distribution network. A comprehensive evaluation method for low-voltage transformer areas of the regional intelligent distribution network comprises the following steps: establishing an intelligent low-voltage distribution network evaluation index model for a plurality of low-voltage transformer areas of the regional intelligent distribution network; acquiring an intelligent low-voltage distribution network actual data value corresponding each intelligent low-voltage distribution network evaluation index in the intelligent low-voltage distribution network evaluation index model; calling a score, which is obtained by rating according to the importance degree of each intelligent low-voltage distribution network evaluation index, in an expert score database, calculating according to the scores to obtain a weight value of each intelligent low-voltage distribution network evaluation index, and giving the corresponding weight value to each intelligent low-voltage distribution network evaluation index in the intelligent low-voltage distribution network evaluation index model; according to the intelligent low-voltage distribution network actual data value of each intelligent low-voltage distribution network evaluation index and the weight of each intelligent low-voltage distribution network evaluation index, carrying out sorting and grading on the plurality of low-voltage transformer areas by adopting a rank sum ratio method. The power distribution transformer areas are comprehensively evaluated, sorted and graded, so that the power distribution transformer areas can be invested and built in a targeted manner.
