Experimental Study on De-icing and Layout of Resistance Wire by Electrical Heating for Wind Turbine Blades
摘要
Abstract
To research the influence rule of external factors on de-icing time and the influence of resistance wire arrangement on the process of ice melting for wind blade by electrical heating,electrical heating de-icing experiments were conducted in artificial climate chamber.The influence rule of ice thickness,environment temperature,relative wind speed and liquid water content (LWC) on de-icing time was analyzed,and a reasonable way of resistance wire arrangement was put forward.Test results show that the effect of ice thickness on de-icing time is more obvious when ice thickness is small,with the increase of ice thickness,there will be no obvious difference on de-icing time;De-icing time decreases with the increase of heating power and environment temperature and increases with the increase of relative wind speed and LWC,in addition,the de-icing time curve along with the change of above factors are quite different under different ice thickness;Chordwise layout of resistance wire is applied on front site of blade and spanwise layout of resistance wire is applied on root of blade;The ice on front site of blade is easily fell off while remaining ice is easily melt.关键词
