摘要
从发电机励磁、调速控制方式入手,在分析了传统综合控制器特点之后,给出了运用非线性逆系统方法实现发电机综合控制的方法,并进行了实验室仿真。仿真结果表明:与传统的常规单变量控制器相比,基于逆系统的综合控制方法不仅能够提高发电机在暂态情况下的系统稳定性,而且能提高电压控制精度。
Starting with the excitation and the governor of hydro turbine generator sets, after analyzing the traditional total automatic generation controller, based on the theory of inverse system nonlinear control, this paper investigates the approach to the multivariable total controller for hydro turbine generator sets in isolated grids. The simulation results indicate, that, compared with the traditional controller, the total controller based on the theory of inverse system can improve not only the system's transient stability, but also the precision of voltage control.
