目前我国配电网络结构还是以辐射型供电方式为主。在城市电网中,对于负荷密集区,大多建有开闭所(开关站),再从开闭所直接向用户供电。开闭所相当于扩展了变电站10kV母线,增加10kV出线。开闭所是配电网底层最基本的单元。对开闭所实时监控,是配电网自动化的基本功能之一。厦门湖 At present, China’s distribution network structure or radiation-based power supply-based. In urban power grids, for load-intensive areas, most of them have an opening and closing station (switch station), and then directly supply electricity to users from the opening and closing. Opening and closing the equivalent of expanding the substation 10kV bus, an increase of 10kV outlet. Opening and closing the bottom of the distribution network is the most basic unit. Real-time monitoring of opening and closing is one of the basic functions of distribution automation. Xiamen Lake
