摘　　要：柔性直流输电(VSC-HVDC)输电容量不断提升,使其应用范围由配电网逐步延伸至输电网,分析交直流混联电网受扰后的稳定性及和设备运行安全,需要开发兼顾大电网计算效率和直流动态特性精细模拟的仿真计算工具。为此,建立了VSC-HVDC电磁暂态仿真模型,包括VSC交流侧换流变压器、直流输电系统和控制系统电磁暂态仿真模型,以及各模型的差分化方程,并提出VSC电磁量与机电量接口转换方法;基于电力系统分析综合程序的用户自定义程序接口(PSASP/UPI)功能,提出并开发实现了VSC-HVDC机电与电磁混合仿真算法。VSC-HVDC交直流并联输电系统混合仿真结果验证了仿真算法的有效性。Based on insulated gate bipolar transistor（IGBT） and pulse width modulation（PWM）, the voltage sourced converters（VSC）-HVDC is a new a generation of high voltage direct current transmission technology and has broad application prospects. With the VSC-HVDC transmission capacity increasing, it is necessary to develop the ac and dc hybrid simulation tool for analyzing and formulating control strategies in order to ensure the DC equipment. The simulation efficiency of large stable operation of hybrid system and the safety of hybrid power grid and simulation accuracy of the dynamic characteristic of VSC-HVDC should be taken into account simultaneously. In this paper, the electromagnetic simulation model is established and the interface conversion method is bring forward for the electromagnetic and electromechanical quantities of VSC. Based on the user program interface function provided by PSASP, the hybrid simulation algorithm is developed. Simulation results of the AC/VSC-HVDC paralleled transmission system algorithm. verified the validity of the hybrid simulation
