35kV小型化模式变电所优化组合的研究与应用

Research on Minified Mode 35kV Substations With Optimum Composition and Its Application

通过两种“小型化模式变电所”接线的优化组合，对主开关部件加以研究改造，使其能适合于既有供电用户又有小水电上网负荷区域运行的３５ｋＶ小型化全户外式变电所，在浙江省余姚市梨洲获得成功。在减少投资、节约土地、缩短周期、降低运行费用等方面效益显著。

Through optimum composition of two type connection of'minified mode 35 kV substations', and studying the reform of main switch components.a whole open type minified mode 35 kV substation has been constructed successfully in Lizhou of Yuyao City,Zhejiang Province. This minified mode substation is appropriate for both of power supply and small hydropower connecting to power grid. It has following advantages:decreasing investment; saving land;shortening the period of construction;and reducing the operation cost etc.
