摘　　要：着重研究发电机励磁系统建模和辨识中的发电机饱和问题,并给出详细的论述和解决方法。将该方法应用于实际情况,以华能412MW汽轮机组为例,对其进行建模和参数辨识,辨识结果通过Matlab和PSSE仿真验证,可以很好地反映实际运行状况,符合实际系统的要求,从而证明了该方法的有效性。The saturation problem in modeling and parameter identification for synchronous generator excitation system was particularly researched in this paper. It also describes how to solve the problem. Take HuaNeng 412MW synchronous generator for example, Modeling its excitation system and identifying the parameters. Using MATLAB and PSSE to check the parameter identification results, Simulation results show that it can accurately reflect the real system. So it can prove this method is efficient.
