摘　　要：近年来提出了基于相量测量单元(PMU)数据的混合动态仿真方法,但如何将PMU信号注入存在不同的方法。文中深入研究混合动态仿真的本质,应用诺顿定理等值简化,提出了一种基于广域测量的变阻抗的电力系统混合仿真方法。并以某大区电网为例,验证了变阻抗方法的正确性,为电力系统动态混合仿真提供了一种简便的等值方法。The idea of hybrid dynamic simulation based on the data from PMU has been proposed recently. However, the specific method to incorporate the external signals into the digital simulation still needs further investigation. After researching on the essence of the hybrid dynamic simulation, this paper applies the Norton equivalent theorem on the hybrid dynamic simulation and proposes a time varying impedance method based on WAMS. Case studies on a real large power system demonstrate the validity of the proposed method.
