| 摘 要： | 本文在分析电励磁双凸极风力发电机工作原理及其控制策略的基础上，针对定桨距风力机，运用叶尖速比法和功率信号反馈法，通过控制发电机励磁电流控制发电机的电磁转矩，调节机组转速，实现最大风能跟踪(MPPT)控制。为研究两种MPPT控制策略的效果，以阶跃风和随机风为例，对两种MPPT控制策略进行了仿真和实验研究，验证了控制策略的可行性与有效性。对两种控制策略进行了对比分析，比较得出功率信号反馈法优于叶尖速比法。

| Abstract: | The operation principle and control strategy of doubly salient electrical-magnet generator are introduced. In this paper where fixed pich wind turbine are focused, The tip speed ratio(TSR) control method and the power signal feedback(PSF) method are applied to make the wind power generator work in the maximum power point tracking(MPPT) mode by regulating excitation current. For example, in step wind and random wind conditions. Simulation and experiment results are carried out, which demonstrate the effectiveness of the control techniques proposed in this paper. Comparing with the two strategies, better performance of PSF are calculated. |
