    • A method of operating a wind turbine having at least one rotor blade and an active flow control (AFC) system is provided. The at least one rotor blade has at least one aperture defined through a surface thereof, and the AFC system is configured to modify aerodynamic properties of the rotor blade by ejecting gas through the aperture. The method includes operating the wind turbine in a normal mode, determining whether an estimated insect density value surrounding the wind turbine is above an insect density threshold value based on a measured environmental condition, and changing a mode of the wind turbine from the normal mode to a cleaning mode different than the normal mode based on the estimated insect density value. The cleaning mode includes adjusting at least one operation parameter of the wind turbine based on the estimated insect density value such that fouling of the aperture is reduced.
    • 提供一种操作具有至少一个转子叶片和主动流量控制(AFC)系统的风力涡轮机的方法。 所述至少一个转子叶片具有通过其表面限定的至少一个孔,并且所述AFC系统构造成通过将气体喷射通过所述孔来改变所述转子叶片的空气动力特性。 该方法包括以正常模式操作风力涡轮机,基于测量的环境条件确定风力涡轮机周围的估计的昆虫密度值是否高于昆虫密度阈值,并且将风力涡轮机的模式从正常模式改变为 基于估计的昆虫密度值的与正常模式不同的清洁模式。 清洁模式包括基于估计的昆虫密度值来调整风力涡轮机的至少一个操作参数,使得孔径的结垢减小。

    • A wind turbine includes a tower member a yaw system, and a wind energy collection system. The wind energy collection system includes a central hub and a plurality of blade members. The wind turbine further includes a component manipulating system operatively coupled between at least one of the plurality of blade members and the tower member. The component manipulating system includes a blade member support structure including a first end pivotally connected relative to the tower member that extends to a second end operatively coupled to the one of the plurality of blade members, and a winching system operatively connected to the one of the plurality of blade members and the tower member. The winching system is selectively operated to shift the one of the plurality of blade members relative to the tower member in order to enable serving of the wind turbine.
    • 风力涡轮机包括塔架构件,偏航系统和风能收集系统。 风能收集系统包括中心毂和多个叶片构件。 风力涡轮机还包括可操作地联接在多个叶片构件中的至少一个与塔架构件之间的部件操纵系统。 部件操纵系统包括一个叶片部件支撑结构,该叶片部件支撑结构包括一个第一端,该第一端相对于该塔架部件可枢转地连接,该第一端部延伸到可操作地连接到该多个叶片部件中的一个的第二端部;以及绞盘系统, 多个叶片构件和塔构件。 选择性地操作绞车系统以使多个叶片构件中的一个相对于塔架构件移动,以便使风力涡轮机成为可能。

The at least one rotor blade has at least one aperture defined through a surface thereof, and the AFC system is configured to modify aerodynamic properties of the at least one rotor blade by ejecting gas through the at least one aperture. The method includes operating the wind turbine in a first mode, determining an environmental condition surrounding the wind turbine indicative of fouling of the AFC system, and operating the wind turbine in a second mode different than the first mode based on the environmental condition. The second mode facilitates reducing fouling of the AFC system.
