基于某地级市配电网35kV发展方式的探究

我国主要的高压配电电压等级有110kV、66kV、35kV,针对35kV高压配电网的供电作用正逐步缩小,文章首先分析了国内35kV电网现状,然后建立了高压配电网需求分析模型,并进行实例分析,最后得出结论:某市B类供电区域2020年9-13个110kV高压布点最合适,35kV布点建议退出。

The main voltage grades of high voltage distribution in our country are 110kV, 66kV, 35kV. In view of the fact thatthe power supply function of 35kV high voltage distribution network is gradually shrinking, this paper first analyzes the present situa-tion of domestic 35kV power network, and then establishes the demand analysis model of high voltage distribution network. Finally,the conclusion is drawn that 9-13 110kV high-voltage distribution points in a class B power supply area in 2020 are the most suit-able, and 35kV distribution points are suggested to withdraw.
