摘　　要：本文研究了瞬态过程中励磁调节系统对汽轮发电机组轴系扭振的影响。以单机300MW汽轮发电机组与无限大电网相连为对象,以电力系统发生单相对地短路、误同期并网以及两相间短路后的重合闸为例,计算分析了励磁系统对汽轮发电机组扭振的作用。The effect of excitation regulation system on torsional oscillation of turbine- generator shaft system during transients is presented in this paper.Using a 300 MW turbine-generator unit connected to an infinite bus as an object of study and taking transient condition consisting single phase to ground short circuit fault,out of phase synchronization and reclosing after phase-phase fault in the power system for example,the effects-of exitation regulation on torsional oscillation of a turbine generator shaft system are analyzed by the aid of calculation.
