TCSC与发电机励磁的自适应鲁棒协调控制方法
Adaptive Robust Coordinated Control for TCSC and Generator Excitation
摘要
Abstract
The transient stability of power transmission system is vulnerable to uncertain parameter and unknown distur?bances,while the control methods based on linearized model on some operation points cannot deal with these uncertain?ties. In order to solve this problem,an adaptive robust coordinated control(ARCC),which combines adaptive backstep?ping algorithm and L2-gain control,is proposed for thyristor controlled series compensation(TCSC)and generator exci?tation. First,the system order is reduced. Then,dissipation inequation is constructed recursively,and the adaptive law and the control law of sub-system are also designed to make the subsystem satisfy dissipativeness,which guarantees the robustness of disturbance suppression of the subsystem. Finally,the simulation results on the single-machine infinite-bus system with TCSC under fault demonstrate that the proposed ARCC method can improve the transient performance of the generator power angle and the dynamic response of voltage at the injection point of TCSC effectively ,which indi?cates that the transient stability of the power transmission system can be enhanced.关键词
