摘要
针对交直流电力系统的稳定性研究中缺乏一种标准的直流模型以及存在不同详细程度的直流模型的问题,基于文献中常见的EPRI直流模型以及电力系统仿真软件PSS/E的CDC4直流模型,提出了一种包含7个不同运行状态的全状态直流模型,并用Matlab程序和PSS/E软件分别对单机无穷交直流系统算例进行了不同故障情况的动态仿真,从而验证了全状态直流模型的正确性。研究结果表明,这种全状态直流模型既具有良好的控制系统,又包含完整的运行状态,很好地满足了要求。
Aiming at the problem of lacking a standard DC model and existing different detail-level DC models in stability analysis of AC-DC power systems,based on the EPRI DC model common in the literature and the CDC4 DC model contained in the power system simulating software PSS/E,a full-state DC model that contains 7 different operating states was recommended,the dynamic simulations of the single machine-infinite bus testing system under different contingencies was made through Matlab program and PSS/E software respectively,therefore the full-state DC model was validated.The results indicate that the full-state DC model has both good control systems and complete operating states,which can well satisfy the requirements.
