多目标非线性励磁控制器的设计

A Novel Design of Multi-objective Nonlinear Excitation Controller

以提高电力系统稳定性和维持机端压电静态调节精度为目标,基于非线性最优预测控制理论,首次设计出具有闭合的解析形式控制律的非线性励磁控制器。仿真结果表明,该控制器在提高稳定性方面有明显的作用且较好地维持了发电机机端电压的静态调节精度,电压超调现象得到很好的抑制。

Major objectives are to improve power system stability and to guarantee generator terminal regulation accuracy. In this paper, based on nonlinear optimal predictive（NOPC）theory, a novel multi-objective excitation controller with closed-form analytic solution control law is presented. The simulation results show that the controller can not only improve the power system stability, but also maintain generator terminal voltage regulation accuracy and restrain voltage overshoot.
