摘要
FACTS(柔性交流输电系统 )元件在系统中具有良好的动态特性 ,充分了解这些特性可以更好地发挥其调节系统潮流、提高系统暂态稳定性的作用。研究了UPFC(统一潮流控制器 )的动态可行域 ,指出了UPFC的动态可行域为类似于椭圆的区域。研究了电力系统中多个FACTS元件动态之间的相互影响 ,仿真分析表明FACTS元件之间存在控制协调问题。由于目前电力系统通信技术的局限性 ,实现FACTS元件之间的协调控制有一定的难度。
FACTS devices have favorable dynamic performance in power system.It is important for us to fully knowing its ability of controlling power flow and improving transient stability.This paper analyzes the dynamic function region of UPFC and indicates that the dynamic function region acts as ellipse.The interaction between FACTS devices in one system is also presented and simulation results show that it is necessary to operate FACTS devices under coordinated control.
