基于Hamilton理论的多机系统励磁与UPFC的非线性鲁棒协调控制器设计
Design of nonlinear robust coordinated controller of excitation and UPFC for multi-machine system based on Hamilton theory
Aiming at the problem of the influence of the uncertain disturbance on the system controller in the multi - machine power system, a new nonlinear coordinated controller with multi-machine excitation and UPFC is designed by using the generalized dissipative Hamilton theory. Firstly, the dynamic equation of multi-machine power systems with UPFC dynamic regulation is established, and the Hamilton energy function of the system is constructed. The system is expressed as a generalized dissipative Hamilton system. Secondly, the nonlinear coordinated controller of multi-machine excitation and UPFC is designed by using the disturbance suppression control theory with parameter perturbation. The controller design process is also applicable to the coordination controller design of other FACTS devices and multi-machine excitation with parameter perturbation. Finally, the four machine two area system is simulated. The results show that the proposed coordinated controller can guarantee the generators’ rotor stability and the better regulation of UPFC’s terminal voltage without static error , and has good robustness under different disturbances.
