中压配电网10kV至20kV升压改造过渡方案研究

Study on transition program of medium voltage distribution network from 10 kV to 20 kV voltage level boost transformation

针对现有中压配电网10 kV至20 kV电压等级的升压改造问题,从主要配电设备特点出发,提出了改造初期利用20/10 kV互联变压器为20 kV供电区域提供电源点的过渡方案,分析了其余升压改造过渡问题,包括两种不同电压等级新旧配电网络的共存和互联、改造初期20 kV配电设备的降压运行。

According to boost transformation of the medium voltage distribution network from 10 kV to 20 kV voltage level,the transition plan was proposed using 20/10 kV transformers to provide power points for 20 kV supply areas in the beginning period of boost transformation.More transition problems were analyzed,including coexistence and interconnection of the two different voltage level distribution networks,step-down running of 20 kV distribution equipments in the beginning period.
