摘要
为了在实验室里完成对风力发电系统的研究,设计了一套以感应电机模拟风机的实验平台。文章首先分析了风机运行的原理,用特性曲线描述了功率、转矩特性。然后讨论了异步电机的控制方法,基于矢量控制,通过对异步电机转矩与转速的控制,使其按照风力机的特性运行。设计了基于DSPTMS320LF2407控制芯片的控制系统。最后给出实验结果,对风速变化及机组转速变化两种典型运行条件下的风力机运行特性进行了模拟实验,实验结果与理论数据基本一致。
In order to imitate wind power generation system in laboratory, this paper designed a experimental system for wind turbine simulator based on induction machines. The paper first analyzed the operation principles of the wind turbine and described power and torque characters with graphs. Then it discussed the theory of operating the induction machinesiaControl torque and rotor speed of asynchronous motor and make it run according to wind turbinei' s characters based on vector control theory. We designed controlsystem using DSP controller TMS320LF2407. In the end, the experimen-tal results was shown. The experiments were done under two typical conditions of variable wind speed and variable machine velocity. The experimental results are almost consistent with theoretical datum.
