摘要
该文引入强跟踪滤波器用于发电机励磁控制,建立了一种新的自适应励磁控制器。该控制器根据发电机运行状态由强跟踪滤波器实时估计系统的扰动信息,准确地获得单机无穷大模型中的系统参数,以调整控制器,使之得以适应系统运行点的变化以及系统遭受的干扰。仿真研究表明,文中所建立的自适应励磁控制器可以有效地提高电力系统的稳定性,在系统遭受不同干扰下均表现出良好的动、静态性能。
A novel adaptive excitation controUer is developed by introducing strong tracking filter in design of excitation controller of generators. According to the running status of the generator the strong tracking filter can acquire real time system parameters of the one machine-infinity bus system accurately. With the real time parameters the excitation controller adjusts itself on line to adapt the change of operating point of the system and disturbances of the system. The simulation results indicate that the presented adaptive excitation controller can improve stability of power system effectively and has good dynamic and static performance towards various disturbances.
