Study on the Operation of VSCF Doubly Fed Wind Power Generator

随着经济发展的不断壮大,对能源的需求指数日渐增长。风能以其优异的特性成为了各国广泛追求的一种新能源,并明显取得好的开端。当前主要两种风力发电技术:恒速恒频和变速恒频,其中变速恒频双馈风力发电机已在当今世界主流机型和研究领域稳占上风,具有广阔的发展前景。重点分析双馈风电机组的矢量控制以及数学模型,通过仿真对风力发电机并网运行进行深入研究,实验结果对双馈风力发电机并网仿真的模型进行了正确的验证。

China＇s rapid economic development, the increasing demand for energy, the focus on new energy and renewable energy is also increasing. Wind as the most competitive renewable energy has become an important goal of the development of various countries, and it has achieved obvious results. Constant speed constant frequency and variable speed constant frequency wind generators are the current main two kinds of wind power technology, the variable speed constant frequency doubly-fed wind power generator with its ef- ficient and practical advantages has become the mainstream of current world model and important field of study. It also has wide development prospects. Detailed introduced in this paper, the mathematical model of doubly-fed wind power generator and vector control principle, through the simulation research of doublyfed wind turbine grid runtime dynamic situation is under control. The simulation results verify the built of doubly-fed wind power generator interconnection the correctness of the simulation model.
