摘　　要：为了提高电力系统的稳定性,提出了一种基于全控器件的新型励磁系统,该励磁系统能通过励磁控制,以及与机端系统交换无功功率,为系统提供双重阻尼。新型励磁系统采用最优协调控制策略,在PSASP环境下进行的单机无穷大系统的数字仿真结果表明,新型励磁系统能够适应运行方式的大范围变化,在大小扰动下较常规自并励励磁系统表现出更好的动态性能。In order to improve the stability of power system,we put forward a novel excitation system based on full controlled devices rectifier, which can provide double kinds of damping for power system by excitation control and exchanging reactive with generator. The novel excitation system uses the optimal coordinated control strategy. The simulation results of the single machine infinite bus system based on PSASP show that the novel excitation system can provide good control performance under various operating points and different disturbances.
