环境参数对小型风力发电机叶片覆冰特性及输出功率的影响
Influences of Environmental Parameters on Icing Characteristics and Output Power of Small Wind Turbine
摘要
Abstract
Icing phenomenon on wind turbine affects its aerodynamic performance, reduces output power. However, the relevant literature are rarely reported. A small horizontal-axis wind turbinewas experimentally investigated in the artificial climate chamber with focus on its icing accretion process. Environment temperature, liquid water content (LWC), and wind velocity were respectively discussed with respect to their effects on icing characteristics and output power of small wind turbine. Experimental results indicate that ice accumulation is relatively large on the leading edge and the windward side of wind blade Moreover, horn-ice generated on the leading edge will lead to a considerable reduction on wind turbine output power. After same period of time, output power of wind turbine decreases firstly and then increases. Consequently, the time that required for wind turbine to shutdown decreases in the first place and then gradually rises along with the decrement of ambient temperature. With the increment of LWC, output power tends to decrease as well as the required time for shutdown becomes shorter. On the contrary, the output power and required time increase along with the wind speed.关键词
