摘要
本文根据励磁稳定控制中的非线性问题,应用微分几何控制理论,提出了多机电力系统发电机励磁非线性反馈解耦控制器的设计方法及相应的闭环非线性解析励磁控制规律。通过对六机系统的仿真结果表明,所设计的控制方式不仅可以有效地改善多机系统的动态响应,而且可以显著地提高多机系统的暂态稳定极限。与其它励磁控制方式相比,具有明显的优越性。
The Contribution of this paper is to propose a new design method and a nonlinear excitation control law which are based on the differential geometric control theory and power system theory for multimachine systems. The control scheme obtained for each generator is not only a decoupled control law among generators but also a stable one. The results of computer simulation to a six-machine system are quite convincing.
