摘要

针对多机电力系统中，发电机励磁和静止同步串联补偿器(static synchronous series compensator，SSSC)的协调控制问题，引入广义Hamilton系统理论，进行非线性协调控制器设计。SSSC采用考虑内部动态的三阶模型，并将SSSC与各台发电机的相互作用用附加电磁功率表示。将包含发电机励磁和SSSC的多机电力系统描述成广义耗散Hamilton系统形式，利用边界函数法和L2干扰抑制控制方法设计了发电机励磁和SSSC的协调控制器。四机两区域系统的仿真结果表明：与传统的分散控制器相比，所提的非线性协调控制器能够有效地提高系统的暂态稳定性和电压调节性能。

Abstract

This paper discusses the coordinated control problem of generator excitation and static synchronous series compensator (SSSC) in multi-machine power systems and designs the nonlinear coordinated controller based on generalized Hamiltonian theory. SSSC adopts a third order model with considering internal dynamics and the interaction between SSSC and each generator is represented as additional electromagnetic power. The multi-machine power systems with generator excitation and SSSC is represented as a form of generalized dissipation Hamilton system. The coordinated control strategy of generator excitation and SSSC is designed by boundary-function method and L2 disturbance attenuation method. The simulation results in two-area four-generator systems show that the proposed nonlinear coordinated controller can effectively improve the system transient stability and voltage regulation performance compared with the traditional decentralized controller.
