摘　　要：对自并励同步发电机的起励进行了仿真研究,起励过程考虑了转子阻尼绕组的影响与发电机空载特性的非线性,以期对起励的动态过程有更深入的认知。给出了某一300WM汽轮发电机自并励励磁的Matlab起励仿真结果,并与现场运行的实测结果进行了比较。The paper studied the simulation of voltage build-up of self-shunt excitation synchronous generator, while considering the effect of damper winding and the nonlinear of no-load characteristic of generator, in order to know the dynamic processes of voltage build-up further. The simulation results of voltage build-up of a 300MW turbine generator were given and compared with the measured field operational results. The simulation results showed viv- idly the dynamic processes of voltage build-up.
