摘要/Abstract

摘要： FACTS控制与传统控制手段缺乏协调可能威胁电网安全稳定。离线控制策略表在不考虑FACTS设备条件下的断面极限过于保守，紧急控制措施较重；而考虑FACTS设备全部容量均可用于暂态过程时，又会导致断面极限过于乐观，紧急控制措施不足。提出了计及FACTS的暂态安全稳定紧急控制策略，将FACTS参与电网暂态稳定控制分为FACTS设备主动调节、紧急执行修正策略和分轮次追加控制3个阶段，将传统暂态安全稳定控制和FACTS控制有机结合，既保证了系统的安全性又提高了控制措施的经济性。以可控串补为例，通过实际电网仿真验证了所提策略，仿真结果表明，通过可控串补参与电网暂态稳定控制，降低了暂态过程中的加速能量，可减少传统暂态稳定控制的切机量，同时维持了电网的稳定运行。

Abstract: The lack of coordination between FACTS control and conventional control may threaten the security and stability of power grid. Without taking FACTS into consideration, the off-line control strategy is too conservative and the emergency control measures are heavy. Meanwhile, if the capacity of FACTS equipment is fully used in the transient process, the section limit will be so optimistic that the emergency control measures may be insufficient. A transient stability emergency control strategy is proposed with consideration of FACTS, which divides the FACTS participated transient stability control into three stages, including FACTS equipment active control, emergency execution correction strategy and in-turn additional control. With the combination of the conventional transient stability control and FACTS control, the system safety is ensured and the economic efficiency of the control measures is improved. The proposed strategy is verified by simulation of a practical power grid. The simulation results show that the participation of the FACTS in the power grid transient stability control can decrease the acceleration energy of the transient process and reduce the cutting-off number of generators while maintaining the stability of the power grid.

Key words: FACTS, transient stability, emergency control, sensitivity, coordinated control
