摘　　要：阐述了电力电子变压器 ( PET)在电力系统的应用前景、特点和方式 ,分析了 PET的解耦控制方法及 PET和发电机励磁的最优协调控制方法仿真结果表明 ,PET在暂态过程中控制性能良好 。The application of power electronic transformer(PET) in power system is presented in this paper. Two kinds of control strategies of PET are proposed, one is decoupled control; and the other is optimal coordination PET and excitation control. Simulation results show that PET can improve power system stability effectively, and has very good control performances in transient process of power system.
