摘要
在分析风力机动态特性的基础上,针对其失速状态工作点不稳定的特点,讨论了一种新型的风力机特性测量方法,建立了一套包括双凸极发电机、直流变换器、虚拟仪器测控装置在内的直驱风力发电系统测控平台。本系统以LabVIEW为核心测控软件,通过对风力发电系统负载的控制,实现了风力机的转速闭环,在风洞实验中,成功测试了某型风力机的气动特性。实验证明了该风机测控系统的可行性和准确性。
Based on the analysis of the dynamic characteristics of the wind turbines, a new method of testing wind turbines was discussed, and a platform was presented, including an double saliency generator, an DC converter, virtual instrument measurement devices. With the help of LabVIEW, the wind turbine rotational speed can be con- trolled with rapid changing of the generator loads. The results of wind tunnel experiments verify the feasibility of the presented system and control strategy.
