摘　　要：文章针对凝冻积冰环境下风电机组叶片气热法防除冰技术展开现场试验,验证其防除冰效果及加热能耗。首先,分析了叶片表面结冰复杂过程并模拟计算NACA64618翼型表面积冰分布;然后,结合2MW风电机组构建叶片主动气热法防除冰系统并实施现场示范工程;最后,开展了风电机组叶片静态除冰试验、防冰试验及防冰生产运行试验,辅助全景红外热成像检测分析叶片防除冰效果及加热能耗。试验结果表明,在冰厚为30mm并控制加热温度为50℃的前提下,持续加热2h后叶片表面开始融冰脱落,加热能耗功率不足50kW。可为风电机组叶片气热法防除冰的工程应用系统设计提供参考。In freezing and icing environment,the field tests of 2 MW wind turbine blades by aerothermal anti-icing/de-icing method is carried out to verify the anti-icing/de-icing effect and energy consumption.Firstly,this paper analyzes the complex process of blade surface icing and then its icing distribution on the surface of NACA64618 airfoil is simulated.Secondly,the blade active aerothermal anti-icing/de-icing system for 2 MW wind turbine is constructed in the field demonstration project.Finally,three tests are finished with the help of the panoramic infrared thermal imaging detection,including the static de-icing test,static anti-icing test and production test with anti-icing,and then evaluate blade anti-icing/de-icing effect and heating energy consumption.The test results show that the blade surface begins to melt and fall off after continuous heating for 2 hours when the ice thickness is 30 mm and the heating control temperature is 50℃,and the heating energy consumption power is less than 50 kW,which can provide a reference for the design of engineering application system of aerothermal anti-icing and de-icing of wind turbine blade.
