    • An apparatus and system for counteracting wind gusts and other high load situations in a wind turbine includes the use of one or more gust counteracting devices configured to extend an air deflector outwardly from a surface of a turbine rotor blade. The air deflector may subsequently be retracted into the rotor blade once the wind gust has subsided or once the load falls below a certain threshold. Mechanisms for extending and retracting the air deflector may include pneumatic or hydraulic systems and/or electromechanical devices. Air deflectors are generally configured to normalize air flow around the rotor blade so that the risk of potential damage to components of the wind turbine is minimized. In one arrangement, the gust counteracting device may be located at a leading section of the turbine blade. Additionally or alternatively, the device may be modular in nature to facilitate the removal and replacement of the device.
    • 用于抵抗风力涡轮机中的阵风和其他高负载情况的装置和系统包括使用一个或多个阵风抵消装置,其构造成将空气导流器从涡轮转子叶片的表面向外延伸。 一旦阵风已经消退或一旦负载下降到某个阈值以下,空气导流板可以随后被缩回到转子叶片中。 用于延伸和缩回导风板的机构可以包括气动或液压系统和/或机电装置。 空气导流器通常构造成使转子叶片周围的空气流正常化,使得风力涡轮机部件潜在损坏的风险最小化。 在一种布置中,阵风抵消装置可以位于涡轮叶片的引导部分。 另外或替代地,设备本质上可以是模块化的,以便于移除和更换设备。
