【摘要】 TCSC的过电压保护主要研究故障情况下保护TCSC和MOV的方式以及如何降低MOV能耗水平,以满足经济性要求,同时又有利于系统暂态稳定。在分析TCSC过电压保护方式与暂态稳定关系的基础上,提出过电压保护的控制策略,研究了保护性旁路的启动方式,并借助ARENE软件予以仿真验证。更多还原

【Abstract】 The research on over-voltage protection of TCSC is mostly about how to protect TCSC and MOV under fault condition as well as how to reduce the energy consumption level. Consequently, the protection can both meet the requirement of economy and benefit the transient stability of system. Based on the relationship between protection mode and the transient stability, this paper proposes the control strategy of over-voltage protection, and studies the start mode of protective bypass. The simulation result is testified by ANENR software in this paper.更多还原
