| 摘 要： | 为了最大限度地利用风能,针对双馈变速恒频风力发电系统,分析了风力机特性及最大风能捕获原理。在基于电网电压定向的矢量控制的基础上,提出了一种新的无需检测风即可实现最大功率点跟踪(MPPT)的控制方法。该控制方法以发电系统输出功率最大为目标,能够实时追踪最大功率点(MPP)且不依赖风力机最佳功率特性曲线,实现了发电机输出有功和无功功率的解耦控制,并构建了风力发电模拟平台进行实验验证,结果证明了该控制方法的正确性与有效性。

| Abstract: | In order to maximizely unitlize wind power,the wind machine characteristics and maximum wind power captured principle are analyzed.Based on vector control technique of grid voltage orientation in doubly-fed variable speed constant frequency wind power system,a new maximum power point tracking(MPPT) control strategy without mea-suring wind speed is proposed.With the objective of maximizing the power output of generation,the control is inde-pendent of optimal turbine power curve and achieve the decoupling regulation of the active and reactive power.The experiment is done in the constructed wind power simulation platform,and the experimental results prove the effec-tive and practical of the control method. |
