摘要
在交流励磁双馈电机两相同步旋转坐标系的数学模型基础上,利用定子磁场定向控制策略,用Matlab/Simulink仿真软件编写了双馈电机在空载运行和发电运行两个阶段的S函数模型程序,再将这两个阶段的模型整合在一起构建了变速恒频双馈风力发电系统空载并网切入及发电运行的仿真模型,最后在给定风况下进行了仿真,并得到了良好的仿真结果,验证了系统的可靠性。
Based on a mathematic model of two-phase synchronous rotating reference frame of AC excitation DFIG,this paper applies Matlab/Simulink software to prepare S-Functions model programs of DFIG at no-load operation and generation operation by stator flux orientation control strategy.Then models of the two stages are integrated to establish a simulation model of VSCF double-fed wind power generation system at no-load parallel cut-in and power generation operation.Finally,the simulation is carried out under the given wind condition and good simulation results are achieved.It verifies reliability of the system.
