风力发电机组高于切出风速的降容增效优化运行

Derating and efficiency optimization operation of wind turbines running above cut-out wind speed

通过对风机降容增效的研究,风机在采取完备的保护措施下,可在高于设计切出风速的一段区间内,降低机组出力继续安全运行。此方法不仅提高了风机自身发电效益,同时也拓宽了风机可利用的实际发电风速范围,有利于提高并网风电场出力的稳定性。

Through the research on the derating and efficiency improvement of wind turbines,it is safe and feasible to reduce the output of the wind turbines with a cut-off wind speed higher than the designed speed to an extend.This method not only improves the power generation efficiency of the wind turbine itself,and also contributes to the continued stability of on-grid wind farms.
