摘　　要：针对复杂电力系统仿真对有效性和精确性的统一要求,提出了综合电磁暂态仿真和机电暂态仿真优点的混合仿真方法。该方法将交直流系统合理分割为若干子系统,利用现有的程序模块采用不同时标的多速积分对各子系统进行仿真分析,考虑晶闸管的通断过程,采用波形松弛技术解决子系统之间的数据接口问题。对3机交直流系统故障的仿真结果表明了混合仿真方法的精确性和有效性。According to the unified requirement to effectiveness and accuracy of complex power system simulation, a hybrid simulation method integrating the advantages of electromagnetic transient simulation and electromechanical transient simulation is proposed. In this method the AC/DC system is reasonably divided into several subsystems and by use of existing program modules the simulation of these subsystems is conducted by multirate integration in different time scale. Considering the switching on/off process of thyristors, the problem of data interface among subsystems is solved by means of waveform relaxation technique. The simulation results of the faults in a 3-machine AC/DC system show that the proposed hybrid simulation method is accurate and effective.
