摘　　要：提出了基于实时数字仿真器(real time digital simulator,RTDS)的电磁–机电暂态混合实时仿真方法。在RTDS/CBuilder环境下,采用多线程和双链表稀疏矩阵技术开发了实时机电暂态仿真程序。提出了电磁和机电侧接口等值电路模型,并将RTDS电磁模型与实时机电暂态程序进行了连接,建立了混合实时仿真平台。该平台可以在详细分析含直流输电局部电网的同时,又能较准确地考虑交流系统对暂态稳定的影响。仿真算例证明了所提混合实时仿真方法的正确性。Based on real time digital simulator （RTDS）, a hybrid real-time simulation method for electromagnetic transient and electromechanical transient is proposed. In the environment of RTDS/Cbuilder and by use of muhithreading and doubly linked list-sparse matrix, a real-time electromechanical transient simulation program is developed. The equivalent circuit models of network interface at electromagnetic side and that at electromechanical side are put forward, and the connection between RTDS electromagnetic model and real-time electromechanical transient program is implemented, thus a hybrid real-time simulation platform is built. When the power grid containing DC power transmission is analyzed in detail, the impact of AC power system on transient stability can also be considered accurately. Simulation results show that the proposed hybrid real-time simulation method is valid and efficient.
