摘　　要：本文利用水电机组机械和电磁过渡过程联合平台,通过对不同负荷模型时水轮机调节系统负荷扰动的仿真研究,探讨了发电机电磁过渡过程和励磁调节对水电机组转速控制的影响。研究结果表明:励磁系统的调节作用和发电机的电磁过渡过程对水轮机调速器的负荷扰动特性有着十分明显的影响,在进行调速器动态特性研究时应计及这种影响。In this paper, the effects of the electromagnetic process and/or excitation regulatang of the generators on hydro-turbine governing systems are investigated. By using a MATLAB-based software platform for simulating the hydraulic-mechanical-electromagnetic combined transient process, the dynamic processes under load disturbance condition with different load mode are calculated. Those studies show that the electromagnetic process and/or excitation action have evidently effects on speed governing of the hydroelectric generating units. So it is necessary to account for those effects for hydro-turbine governing system research.
