多机电力系统非线性自适应励磁控制器设计

Nonlinear Adaptive Excitation Controller Design for Multi-machine Power Systems

结合Backstepping方法和滑模控制,同时考虑电力系统的参数不确定性,设计了励磁控制器实现对多机电力系统的励磁解耦控制。采用3机9节点系统进行数字仿真,在不同仿真情况下该励磁控制器均能确保发电机运行稳定且具有较强的鲁棒自适应性。

By combining the backstepping method with the sliding mode control and considering the parameter uncertainty of the power system, excitation controller is designed for the excitation decoupling control of multi-machine power system. Finally, the simulation results of a 3-machine 9-node power system under different simulation conditions show that the excitation controller can guarantee the stability of generators and has strong robustness and adaptive performance.
