提出了一种新的交直流混合模型暂态稳定仿真算法，该算法将动态相量理论应用于高压直流输电系统的建模，而将传统的机电暂态模型用于交流系统的建模。首先推导了基于动态相量的高压直流输电系统的详细模型，然后提出了直流动态相量模型与交流网络的接口算法。计算机仿真结果表明，与电磁暂态模型相比，该模型具有很好的精度；两区域交直流系统和多馈入直流系统的试验结果表明，所提出的接口算法在系统暂态稳定分析中是有效的。该混合模型仿真算法为大规模交直流电力系统的动态仿真提供了一种新的途径。
A novel hybrid-model transient stability simulation algorithm for ac/dc power systems is suggested in this paper, where dynamic phasors theory is applied for HVDC transmission system modeling, and traditional electromechanical transient models are used for ac system. A detailed dynamic-phasors-based HVDC system model is derived first, and the algorithm for interface of the dc dynamic phasors model to ac network is proposed next. Computer simulation results show that the HVDC dynamic phasors model has very good accuracy as compared with its electromagnetic transient model; the test results from a 2-area ac/dc power system and a multi-infeed HVDC power system show clearly that the suggested interface algorithm works effectively in system transient stability analysis. The proposed hybrid-model simulation algorithm provides a new approach for dynamic simulation of large-scale ac/dc power systems.
