摘　　要：为实现大功率电力电子装置特性的全面物理测试,将装置的动态过程划分为装置级电磁暂态过程、器件级开关暂态过程和热动态过程,并对这3个动态过程进行实时交互计算。基于分段插值拟合方法实现了开关暂态实时化功能模型,并在此基础上实现混合实时数字仿真平台。通过一台±50M var静止无功发生器装置的仿真应用实例,说明所提出的混合实时数字仿真方法可以事先对电力电子装置的控制和保护系统进行全面有效的物理测试验证。To realize accurate testing of the control and protection systems, the transients in a high power electronic system are classified as electromagnetic transients, switching transients, and electro-thermal transients. A real-time hybrid simulator was developed. In the developed simulator, the real-time behavior model of power switching devices was proposed based on piecewise interpolation fit. The developed simulator was used to analyze a ± 50 Mvar static synchronous compensator. The simulation results verify the feasibility of the real-time hybrid simulator.
