摘　　要：针对国内外常见电力系统仿真平台大多基于闭源商业软件开发,源码封闭、盗版泛滥等问题,在分析网侧变流器的数学模型和前馈解耦双闭环的控制策略的基础上,提出在开源软件Scilab建立元件级网侧变流器的模型,在Scilab/Xcos平台上将面向物理对象的建模语言Modelica引用到网侧变流器的元件开发中,最终在Scilab/Xcos平台中建立可控电压源和IGBT等元件,完成网侧变流器及其控制系统模型的搭建,对电网三相平衡和机侧电压扰动时的状态进行仿真,验证了元件开发和模型搭建的正确性,以及在Scilab/Xcos平台进行电力系统仿真的可行性。Most common power system simulation platforms at home and abroad are based on closed⁃source commercial software development,with closed source code and rampant piracy.The mathematical model of the grid⁃side converter and the control strategy of feedforward decoupling double closed loop were analyzed.On this basis,the model of the component level grid⁃side converter in the open source software Scilab was established.On Scilab/Xcos platform,the physical object⁃oriented modeling language Modelica was introduced into the component development of the grid⁃side converter,the controllable voltage source and IGBT and other components were established in Scilab/Xcos platform,and the model of the grid⁃side converter and its control system was completed.The simulation of the three⁃phase balance of power grid and the state of generator side voltage disturbance obtained reasonable results,which verifies the correctness of component development and model building,as well as the feasibility of power system simulation on Scilab/Xcos platform.
