摘要
将Ｌｙａｐｕｎｏｖ稳定性理论用于电力系统的非线性励磁控制，推导了实用的发电机非线性最优励磁控制规律。通过理论分析、计算机仿真和动模实验，证实了该控制方式具有较强的鲁棒性，在系统参数或运行状态变化时都具有良好的控制效果。而且，励磁控制规律的获得不必经过繁杂的数学推导，易为工程技术人员所掌握，具有明显的实用价值。为电力系统的励磁控制研究开辟了一条新的途径。
In the paper,the Lyapunov stability theory is used on electric power system' s nonlinear excitation control and a practical nonlinear excitation control law of generators is studied. The theory analysis ,computer simulation and the experiment study on the micromachine system in the laboratory show that thecontrol methed is robust. It possesses better control effect , when the system parameters or operation conditions are varied to obtain. The excitation control law, there ls no need of complicated mathematic cacula-tion, so it is easy to be mastered by engineers and technicians.
