固态切换开关强迫切换策略研究

Study of Forced Commutation Strategy for Solid State Transfer Switch

从固态切换开关与电网拓扑结构的相互影响的角度出发,研究了固态切换开关的切换策略,提出了一种适用于10 kV中性点经Z型变压器接地的双电源系统的强迫切换控制策略。试验表明,该策略缩短了固态切换开关的切换时间,减小了切换过程对负荷的影响。

The switch strategy of solid state transfer switch is researched in terms of the mutual effect between solid state transfer switch and power system topology frame respectively.A forced commutation strategy is put forward to 10 kV double-source power system with zigzag grounding transformers.it shortens the switching time of solid-state switch and reduces the switching process on the load.
