【Abstract】 Based on super mixed real-time simulation( SMRT),which interfaces real-time digital simulation( RTDS) and digital computer,this paper presents the architecture design and basic implementation,and the difficulties and key techniques for utilization of hybrid simulation in AC and DC power system. Key techniques on howto smoothly interface the electromagnetic and electromechanical transient simulation modes are studied and described in detail,including stability analysis and stabilizing method for the computational system. practical equivalent interface impedance in lowfrequency band,leading estimation of interface states based interface and interaction protocol,asymmetric interface method by three-sequence current injection,and three-sequence fundamental power calculation with closeloop auto calibration correction. Finally,the overall scheme and key techniques are verified by case analysis. More tests and practices have proven that SMRT basically meets the requirement of synthesis transient processes simulation of large AC and DC power system.更多还原
