摘　　要：由于基于RTDS的机电—电磁混合实时仿真受到CBuild本身的众多限制,目前机电侧规模远不能满足仿真规模的需要。提出了将动态等值应用到混合实时仿真中,在不失精度的前提下,可以大规模扩大机电侧仿真规模。对IEEE 14节点系统进行动态等值,并将其与实际直流系统进行混合仿真,对比等值前后仿真结果,证明了动态等值应用在实时混合仿真中的可行性和准确性。Because the RTDS-based electromechanical-electromagnetic hybrid real-time simulation is limited considerably by the CBuild itself,the current electromechanical side scale by far cannot meet the need of the simulation scale.It was proposed that applying the dynamic equivalence in hybrid real-time simulation could significantly enlarge the electromechanical simulation scale without losing the precision.The dynamic equivalence was carried out on the IEEE14 node system and the hybrid simulation was carried out on it with the actual direct current system.The simulation results before and after the equivalence were compared,which proved the feasibility and accuracy of the application of the dynamic equivalence in real-time hybrid simulation.
