摘　　要：本文提出了多机电力系统再同步附加断续控制原理,导出了再同步附加断续励磁、快关汽门、电制动的控制规律。并进行了数字仿真和动模实验的验证,结果表明该控制方式能保证失步发电机快速可靠地再同步。A supplementary discrete control strategy for generator resynchronization in multima-chine systems is presented in this paper. The supplementary discrete control schemes of the exitation, the fast valving and the brake resistance are also suggested. The digital simulations and the extensive study in a scaled machine-system have been carried out. The results of the studies show that the discrete control schemes are able to ensure a fast and reliable resynchronization of the generator in case of its losing synchronism.
