摘 要:该文提出基于虚拟电阻补偿的功率接口建模方法,以提高用于MMC-HVDC的数字物理混合仿真系统的稳定性。通过分析现有采用电压源型理想变压器法建立功率接口模型的混合仿真系统的稳定性条件,在数字仿真系统受控电流源的控制量中引入虚拟电阻电流补偿,分析含改进功率接口模型的仿真系统的稳定性。综合考虑稳定性和仿真精度,对虚拟电阻取值进行优化设计。搭建含所提改进功率接口的双端双极柔性直流输电系统的仿真模型,进行稳态及暂态运行条件下的仿真结果对比。所提方法可有效提高混合仿真系统的稳定性,同时具有仿真精度高、易于实现的特点。To improve the stability of the digital-physical hybtSd simulation system of the modular multilevel converter-based high voltage direct current (MMC-HVDC) system, a novel power interface modeling method based on the virtual resistance compensation was proposed in this paper. By analyzing the stability condition of the current hybrid simulation system based on the voltage source ideal transformer model, the current of a virtual resistance was introduced to compensate the control signal of the controlled current source in the digital simulation system, and the stability of the hybrid simulation system with the improved power interface model was analyzed. The value of virtual resistance was optimized by comprehensively considering the system stability and simulation accuracy. A two-terminal bipolar MMC-HVDC simulation system based on the proposed power interface was established. The simulation results under steady-state and transient state verify that the proposed method can effectively improve the stability of the hybrid simulation system, and has the advantages of high simulation accuracy and easy implementation.
