我国南方风电场冬季风电叶片除冰方法探讨

Study on Deicing Operation of Wind Turbine Blade Located in a Wind Farm of South China in Winter

以南方某风电场为实际案例,根据该地区的地理和气候特点分析风电叶片覆冰特征,并针对设计制造中未考虑防除冰措施的在役风电机组,在保证其安全运行前提下,现场尝试交替控制风力机的停机和开机进行叶片除冰操作,达到了良好的效果,提高了发电效率。实践证明该方法在类似场合操作简便、运行可靠、成本低廉。

Based on a wind farm of south China, the characteristic of icing covered on a wind turbine blade was analyzed, and the icing operation with power on and off alternately on the premise of guaranteeing safe running was attempted for the wind turbines that have not been considered about icing in design. A satisfactory result with high power generating efficiency was achieved finally. Practice has proved that the operation was convenient, reliable and low -cost in the similar condition.
