摘要论文研究了含静止无功补偿器（SVC）的多机电力系统的暂态稳定性。首先将含SVC的多机电力系统转化为微分代数系统的耗散Hamiltonian结构,然后利用Hamiltonian函数方法设计了发电机自动电压调节器和SVC的鲁棒分散协调控制器。通过选择合适的参数,该控制器同时也是L₂扰动衰减控制器（AVR）。仿真结果表明,与传统的AVR/PSS励磁控制器和PID SVC控制器及发电机励磁与SVC的反馈线性化协调控制器相比较,本文提出的发电机与SVC L₂鲁棒协调控制器能有效提高电力系统的暂态稳定和电压调节性能。

Abstract：In this paper, the transient stability of multi-machine power system is investigated. Firstly, we express a multi-machine power system with static var compensator (SVC) as a dissipative Hamiltonian structure. Then, using the Hamiltonian function method, an automatic voltage regulator (AVR) for generators and a robust decentralized coordinated controller for SVC is proposed. By choosing appropriate parameters, the proposed control scheme in this paper is also an L₂ disturbance attenuation controller. Finally, compared with the coordinated controller of AVR/PSS (power system regulator), the proportion-integration-differentiation (PID) SVC controller, and the feedback linearization coordinated controller for the excitation and SVC, the simulation results indicate that the proposed coordinated control scheme can improve both the transient stability and the voltage regulation performance of the power system more effectively than the other coordinated control schemes.

Key words： Automatic voltage regulator of generator Hamiltonian function method static var compensator coordinated control
