摘　　要：MMC电力电子设备的广泛应用和交直流混联电网的快速发展对电力系统仿真技术提出了更高的要求。提出了基于"FPGA+RTDS+并行机"异构平台,具有快速电磁暂态、常规电磁暂态和机电暂态联合仿真功能的交直流大电网多时间尺度混合实时仿真系统。该仿真系统由VSC设备、HVDC系统和交流系统等几个仿真子平台组成,通过闭环接口实现时间上多尺度步长、空间上多颗粒度并行的多模式联合仿真计算,并能与EMS系统以及具有EMS画面风格的调控模拟及特性展示系统进行接口,为交直流复杂大电网运行分析和试验研究提供了精确高效的仿真平台。With the wide application of modular multilevel converter （MMC） power electronic devices and the rapid development of AC＆DC hybrid power grid, the higher demand is required for the power system simulation technology. A multi-time scale hybrid real- time simulation system for AC ＆ DC large-scale power grid is presented, which is based on the ＂FPGA ＋ RTDS ＋ PC （parallel computer）＂ heterogeneous platform and is able to carry out hybrid simulation of fast electromagnetic transient, electromagnetic transient and electromechanical transient. The simulation system is composed of several simulation sub-systems such as VSC device, HVDC system and AC power system. Connected together by closed-loop interfaces, the system can implement multi-mode united calculation in multitime scale and multi-grain parallelism. The system can also be interfaced with the EMS （energy manage system） as well as the dispatch control and characteristics display platform. Thus an accurate and efficient simulation tool for the test and study on complex ACSJ3C large-scale power grid is provided.
