摘　　要：发电机励磁与FACTS设备的协调控制是提高电力系统稳定性较为经济和有效的措施之一。基于广义Hamilton理论提出了发电机励磁与可控串补(Thyristor Controlled Series Compensator,TCSC)的协调控制方法。首先构造系统的Hamilton能量函数,将含TCSC的单机无穷大系统(Single Machine Infinite Bus,SMIB)表示为广义耗散Hamilton系统;然后采用能量补偿和阻尼注入的思想设计了发电机励磁和TCSC的协调控制器,物理意义更为清晰;最后用仿真算例进行验证,结果表明该控制策略可以提高系统阻尼,能够有效改善系统的稳定性。The coordinated control of generator excitation and FACTS device is an effective and economical measure to improve power system stability. This paper proposes a coordinated control strategy of exciter and TCSC based on generalized Hamilton theory. The Hamiltonian energy function is constructed via which the dynamic of the Single Machine Infinite Bus system （SMIB） with Thyristor Controlled Series Compensator （TCSC） can be expressed into generalized dissipative Hamilton system. An energy compensation and damping injection method, with a more obvious physical meaning, is used to design the coordinated control law of excitation and TCSC. Simulation results of a practical power system demonstrate that the proposed control strategy can increase the system damping and improve the stability of the system.
