针对1.5 kW分布式新型变桨风力机
通过数值模拟方法计算均匀来流和切变来流条件下的结构动力响应
分析桨距角、风速、剪切指数变化对新型变桨风力机叶片结构动力响应特性的影响规律。结果表明:随着桨距角的增加
风力机叶片的应力响应及位移响应明显降低
且来流风速或剪切指数越大
其降幅越大;在切变来流条件下
风力机叶片所受应力响应和位移响应均随剪切指数的增加而增加;在复杂风况下变桨距调节方式对于叶片降载具有可行性
同时可为分布式风力机在复杂风况下的结构及性能优化提供参考。
For the 1.5 kW distributed new type of variable pitch wind turbine
the structural dynamic responses under uniform inflow and shear inflow were calculated with the numerical simulation method
and the influences of pitch angle
wind speed and shear index on the structural dynamic response characteristics of the new type of variable pitch wind turbine blade were analyzed. Results show that the stress response and displacement response of wind turbine blades decrease significantly with the increase of pitch angle
and the larger the incoming wind speed or shear index is
the greater the decrease is. Under the condition of shear flow
the stress response and displacement response of wind turbine blades increase with the increase of shear index. The variable pitch adjustment method is feasible for the blade load reduction under complex wind conditions
witch can provide a reference for the structure and performance optimization of distributed wind turbines under complex wind conditions.
