The fault repair work of distribution network is an important part of distribution network operation.The quality and efficiency of repair work are of great significance to the improvement of the power supply reliability and service quality of distribution network.However,there are some difficulties in the evaluation of fault repair work at present.This paper takes fault repair as the entry point,and investigates and analyzes 95598 fault repair work orders from 3 dimensions of time,space and fault type;on this basis,the evaluation indexes that can accurately reflect the quality and efficiency of fault repair of distribution network are determined,the indexes are compared and evaluated by the way of scoring,and the weights are determined by using the analytic hierarchy process and entropy method,and the comprehensive score is obtained by weighted sum,thus a set of clear and practical evaluation system for the quality and efficiency of fault repair of distribution network is established.Finally,taking Nanjing as an example to evaluate the quality and efficiency of distribution network fault repair in each area,and the weak points of repair work are excavated by comparison and evaluation,and the operation management level and the high quality service level of distribution network are improved.
