摘　　要：灵活交流输电(Flexible AC Transmission System,FACTS)装置在电力系统中应用广泛,开展基于广域测量系统(Wide-area Measurement System,WAMS)的多FACTS协调控制研究是未来FACTS发展的主要方向之一。建立了广域集中协调控制架构,采用动态输出反馈控制结构,利用凸多面体的微分包含理论,提出了一种适用于多种工况的多FACTS协调控制算法;针对WAMS信号存在的固有时滞特性分析了算法的时滞裕度,使得算法在裕度范围内均可保证系统稳定运行。最后含SVC和TCSC的多机算例验证了所提算法,表明算法在多种工况中均表现出较好的控制效果,保证系统在强阻尼模式下运行。With the wide application of flexible AC transmission system （FACTS） in power system, one of the major directions of FACTS development is the research of multi-FACTS coordinated control based on wide-area measurement system （WAMS）. The wide area centralized coordination control architecture is established. Based on the structure of the dynamic output feedback control and the theory of the polytopic linear differential inclusion, a wide-area multi-FACTS coordinated control algorithm for multiple load cases is proposed. In virtue of the output feedback signals from WAMS, the delay margin is analyzed within which the algorithm can ensure the stable operation of power system. The algorithm is validated in a 4-machine, 2-area system with static var compensator （SVC） and thyristor controlled series capacitor （TCSC）. The result shows that the power system sucessfully runs in strong damping modes in multiple load cases.
