摘　　要：提出一种基于自由权矩阵方法的多灵活交流输电系统(FACTS)抗时滞协调控制算法。该算法采用广域测量系统(WAMS)的输出反馈信号,考虑信号的传输时滞,使用自由权矩阵时滞稳定定理作为判据,同时保证时滞系统的最小阻尼比在一定阈值之上,利用量子遗传算法寻优获得多FACTS协调控制器的最佳增益。2台静止无功补偿器(SVC)算例的时域仿真结果验证了所提算法的有效性。An algorithm based on free-weighting matrix approach is proposed for the anti-delay coordinated control among multiple FACTSs（Flexible AC Transmission Systems）, which uses the output feedback signal of wide-area measurement system,considers the time delay of signal transmission,adopts the free-weighting matrix time delay stability theory as criterion,ensures the minimum damping ratio of time delay system above a given threshold,and applies the quantum genetic algorithm to obtain the best gain of multi-FACTS coordination controller. Results of time-domain simulation for a case with two SVCs show its effectiveness.
