摘　　要：在利用小型同步发电机仿真大型同步发电机时,需要提高时间常数。本文提出一种方法,在可控硅励磁控制系统内引入励磁电流反馈进行T_(do)的补偿,理论与实践证明,该方法具有经济、精确、方便等优点,宜于在模拟同步发电机的励磁系统实施。When a small-scale synchronous generator is used to simulate a large-scale one, T_(do)must be increased. A local feedback is introduced into the SCR excitation control system to compensate T_(do) in this paper. The theoretical and application results prove that the proposed method has the advantages of economy, accuracy, convenience and etc., especially, is suitable for the synchronous generators used for simulation.
