摘　　要：VSC-HVDC的优势备受关注,我国首个VSC-HVDC示范工程已开始建设。采用基于dq同步旋转坐标系的VSC-HVDC连续时间状态空间数学模型时,使用电压空间矢量PWM(SVPWM)方便直接。基于PSCAD脚本构造自定义模块,给出了SVPWM在PSCAD/EMTDC中的建模和实现。将此SVPWM模块应用于VSC-HVDC,在PSCAD/EMTDC进行仿真,验证了其正确性和有效性。VSC-HVDC is very attractive for its advantages,and the first VSC-HVDC project has been being built in our country. The modeling and implement of SVPWM is presented based on the user-defined models using PSCAD script in PSCAD/EMTDC. Applying the model of SVPWM to VSC-HVDC and simulating in PSCAD/EMTDC verify the validity and effectiveness.
