为了预测高山风电场风机叶片表面覆冰/融冰情况,本文通过正交试验法设计工况,利用数值仿真的方法模拟了不同工况下风机运行时叶片表面的覆冰情况以及停机时叶片表面的融冰情况,建立了基于气象参数的覆冰/融冰厚度预测模型。此外,对得到的覆冰/融冰模型做了参数分析,结果表明,在覆冰条件下,温度的减小、翼型合速度和绝对湿度的增加都会增加叶片表面的最大覆冰厚度;在融冰条件下,温度、风速、相对湿度的增加也会增加叶片表面的融冰厚度。 |

In order to predict the icing/melting states on the surface of wind turbines in alpine wind farms, this paper designed the conditions by orthogonal test method, simulated the icing conditions on the surface of wind turbines at different working conditions by numerical simulation method, and established the prediction model of icing/melting thickness based on meteorological. In addition, the parameters of the icing/melting model are analyzed, and the results show that the maximum ice thickness of the blade surface is increased with the decrease of temperature, increase of profile closing speed and absolute humidity at icing conditions. At melting conditions, the increase of temperature, wind speed and relative humidity will also increase the melting thickness of the blade surface. |
