摘　　要：根据两电平空间电压矢量脉宽调制(SVPWM)的基本原理,在电磁暂态分析软件PSCAD/EMTDC中,创建了自定义元件,以实现SVPWM功能。主程序用FORTRAN语言编写,主要包含参考矢量所在扇区判断、空间矢量工作时间计算、工作时间分配等功能模块。基于该元件,进行了仿真实验,仿真结果表明了元件的正确性。According to the basic principle of the two-level space vector pulse width modulation （ SVPWM ）, this paper creates a self-defined component in electromagnetic transient analysis software PSCAD/EMTDC in order to achieve SVPWM function. The main program is edifed by FORTRAN language, which is mainly used to determine the reference voltage in the sector, calculate and distribute the working time for space vector and so on. The simulation is established in PSCAD/EMTDC by using the self-defined component. Simulation results demonstrate the correctness of the component.
