摘　　要：双馈风电系统的建模仿真对其运行原理、故障诊断及预测等研究具有很大便利性.文中在对风电系统数学模型进行分析和理论阐述的基础上,在Matlab/Simulink中建立其正常动态下的仿真模型,并通过加入故障块实现转子短路故障的仿真;通过将模型整体进行Mask封装设计其GUI和代码生成的方式,提高模型的便捷性和可移植性,便于仿真不同参数的系统和实现结合嵌入式等系统进行研究使用.通过仿真结果表明,文中所建模型具有很好的合理性及适用性,能很好仿真双馈风电系统的实际运行情况,可为风电系统的研究提供一个良好的模型基础.The modeling and simulation of the doubly-fed wind power system is very convenient for its operation principle,fault diagnosis and prediction.Based on the analysis and theoretical explanation of the mathematical model of wind power system,the simulation model under normal dynamics is established in Matlab/Simulink,and the simulation of rotor short-circuit fault is realized by adding fault block.By encapsulating the model as a whole with Mask and designing its GUI and code generation methods increase the convenience and portability of the model,and facilitate the simulation of systems with different parameters and implementations in conjunction with embedded systems.The simulation results show that the model built in this paper has good rationality and applicability,which could simulate the actual operation of the doubly-fed wind power system well.The research provides a good model foundation for the research of wind power system.
