配电网故障抢修质量与效率评价体系研究

故障抢修工作是配电网运行的重要环节,提升抢修工作的质量和效率对于提高配电网供电可靠性和服务质量具有重要意义,但目前对于故障抢修工作的评价存在着一定的困难。本文以故障抢修为切入点,从时间、空间和故障类型3个维度对95598故障报修工单进行调研统计。在此基础上,确定能准确反映配电网故障抢修质量与效率的评价指标,采用打分的方式对各指标进行直观对比评价,并采用层次分析法和熵权法确定其权重,加权求和得到综合得分,从而建立一套明确且实用的配电网故障抢修质量与效率评价体系。最后,以南京市为例,对其各区域的配电网故障抢修质量与效率进行评价,挖掘抢修工作的薄弱点,提升配电网运行管理和优质服务水平。

Quality and Efficiency Evaluation System of Distribution Network Fault Repair

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.
