摘　　要：针对电磁暂态分析软件包PSCAD/EMTDC库文件中没有现成的能实现空间矢量脉宽调制(SVPWM)算法元件的问题,根据两电平SVPWM的基本原理,在PSCAD/EMTDC里创建了自定义的两电平SVPWM算法元件。介绍了两电平SVPWM的基本原理、自定义元件的创建过程以及SVPWM元件主程序的流程图,对各主要功能模块的算法也进行了详细的分析。基于该自定义SVPWM元件进行了仿真实验,仿真结果表明了自定义SVPWM元件的正确性和有效性。There isn＇t a component which can implement the algorithm of space vector pulse width modulation （SVPWM） in PSCAD/EMTDC master library. According to the principle of two-level SVPWM, this paper creates a self-defined two-level SVPWM component in PSCAD/EMTDC. The principle of SVPWM is explained firstly. Then the creating process of self-defined component and the program flowchart of SVPWM component are presented. The algorithms of the main subroutines are also discussed in detail. Finally, the simulation is made using the self-defined SVPWM component. Simulation results demonstrate the correctness and validity of the self-defined SVPWM component.
