小型风力机偏航时输出功率的计算和实验验证

The application of the theorem momentum on the fixed yaw turbine

利用风力机在固定偏航时的动量定理,分析了风力机的功率随偏航角的变化规律。对300W样机进行了外特性测试,通过将理论计算的结果与实验测试结果进行对比,分析了动量定理在风力机偏航时应用的可靠性及存在的问题,为今后风力机偏航时的功率评估提供了一定的理论依据。

The momentum theorem was used to analyze the variation of the wind turbine power with yaw angle . Through doing a test about the external characteristics of a 300w wind turbine, and comparing the results of theoretical calculations with the results of experimental test, it analyze the reliability and the existing problems when the momentum theorem was used in a fixed yaw angle . However, It provides certain theory basis to the assessment of the wind turbine power when the wind turbine in a fixed yew angle in the future.
