2MW风电机组叶片防除冰试验与能耗评估
Blade anti-icing/de-icing test and energy consumption evaluation of 2MW wind turbine
摘要
Abstract
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.关键词
