摘要
在已有风力发电测试与实验一体化系统基础上,研制了一台用于风力机特性测试以及系统控制研究用的DC/DC变换器。并对变换器的动态性能进行了优化设计,满足了该系统叶尖速比大范围变化时超宽的转速和功率运行要求。结合风力发电测试与实验一体化系统进行了风洞试验,测试了某2kW风机的气动特性曲线。实验结果表明该变换器能够很好地满足风机测试和正常工作的要求。
A new type of DC/DC converter is designed and produced on the existing wind power testing and experimental integration system.After some optimal design,this converter meets the operational requirements of ultra-wide changing of wind speed and power,which results from the wide-range changing of tip speed ratio.Then the wind tunnel experiments are done and the Cp-λ curve of a certain 2 kW wind turbine is measured out.The experimental results show that the designed converter can adapt the operational requirements of the system well.
