摘　　要：对高压直流输电和柔性交流输电系统设备的准确仿真需建立详细的电磁暂态模型,而大电网中建立所有设备的电磁暂态模型来进行计算是不现实的,针对该问题,采用了3个典型算例,详细介绍了应用电力系统全数字实时仿真装置的混合仿真功能进行大规模电网仿真的过程。将大电网分为电磁暂态子网和机电暂态子网,其中大电网局部或某些关注的设备作为电磁暂态子网,其余网络作为机电暂态子网,电磁暂态子网中的设备用详细的电磁暂态模型描述。将混合仿真计算结果与传统的机电暂态仿真结果相比较,验证了混合仿真的准确性。To accurately simulate the equipment equipped in high voltage direct current （HVDC） power transmission and flexible AC transmission systems （FACTS）, it is necessary to build detailed electromagnetic transient models for them, however it is unrealistic for the computation to build electromagnetic transient models of all equipment in large-scale power grid. Utilizing the hybrid simulation function in advanced digital power system simulator （ADPSS） and dividing large-scale power grid into electromagnetic transient ＂sub-grid and electromechanieal sub-grid, thus a part of large-scale power grid or some equipment that are paid close attention to are regarded as electromagnetic transient sub-grid and the rest part as electromechanical sub-grid, and the equipment in electromagnetic transient sub-grid will be described by detailed electromagnetic transient models. Taking static vat compensator （SVC）, thyristor-controlled series compensator （TCSC） and HVDC line as typical simulation examples, the course of applying ADPSS to hybrid simulation of large-scale power grid is presented in detail, and comparing with the results from electromagnetic simulation it is proved that the results from hybrid simulation results are much higher accurate.
