摘要
为了在不具备风场环境的情况下进行风力发电技术研究,设计了一套双馈风力发电实验平台。通过建立随机风速模型和风轮机转矩输出特性计算式,利用变频器控制直流电机的输出转矩来模拟风轮机的输出特性,通过dSPACE来控制双馈变频器进行异步电机的变速恒频控制,使用LabVIEW软件对整个系统进行统一监控和管理。
Because of no wind farm circumstance in the lab,it is hard to do the actual experiment except the theoretic analysis and the simulation of computer.In order to solve this problem,this paper proposed a design and realization of doubly fed induction generator for wind-energy Generation System.The wind speed mathematical model is established as well the calculating function of wind turbine,which is output by using DC motor.The variable-speed constant-frequency control of induction motor is implemented by dSPACE system.The whole system is supervised and controlled by LabVIEW software.
