县域配电网供电能力评估分析

Evaluation of power supply capacity in county distribution network

通过对陕西省西乡县域配电网现状分析,基于模糊理论研究了西乡县域配电网的供电能力,分别选取了线路线损率、主干线路负载率、线路电压合格率、主变容载比及配电网"N-1"运行校验合格率等因素进行评价。利用评价结果,对西乡县域配电网的整体供电能力进行了评估分析,提出西乡配电网改造建设性的规划建议。

Based on an analysis of the present situation of Xixiang county distribution network, and fuzzy theory, the study mainly probes into the power supply capacity of the distribution network in Xixiang county. Factors, such as wire loss rate, wireload rate, voltage qualification rate, the main transformer capacity load and distribution network ＂N-1 ＂ check qualification rate, are selected as major variables for evaluation. After an analysis of the factor evaluation, suggestions on future planning and building of power distribution network are made.
