摘要: 针对MW级风电叶片气热抗冰技术建立了加热融冰过程中的热力学模型,对复合材料叶片表面融冰时间进行了计算,其结果与有限元仿真计算结果误差小于7%。对风场服役的2 MW机型叶片进行融冰实验,结果表明,气热抗冰系统在环境温度为-10 ℃的条件下可以有效融冰/防冰。

Abstract: Based on the principle of hot-air heating method, a anti-icing thermodynamics computational model is established for MW wind turbine blades. The model is used to calculate the time for melting ice attached on composite surface. The results show good agreements between the mathematical model and FEA. Then a hot-air heating anti-icing system designed by means of FEA, is equipped in a 2 MW wind turbine. The test in wind-farm shows that, in -10 ℃ environment, ice on the surface of blades starts to be melt in 45 minutes. This system could be applied to anti-icing of wind turbine blades.

Key words: wind-turbine blade, hot-air anti-icing, wind-farm test
