Abstract: There is provided a method for controlling a hydraulic pitch force system (220) so as to reduce or eliminate a decrease in hydraulic oil pressure (241) if a hydraulic system parameter value is outside a hydraulic system parameter range, the method comprising: Obtaining (690) the hydraulic system parameter value, and operating the hydraulic pitch force system (220) according to a reduced mode (692) if the hydraulic system parameter value is outside the hydraulic system parameter range, wherein in the reduced mode one or more pitch based activities are reduced (694) or suspended. An advantage thereof may be that it enables keeping the wind turbine in production in certain instances rather than shutting down the wind turbine. In aspects, there is furthermore presented a computer program product, a pitch control system (250) and a wind turbine (100).

Abstract translation: 提供了一种用于控制液压变桨力系统（220）的方法，以便在液压系统参数值在液压系统参数之外时减少或消除液压油压力（241）的减小 所述方法包括：获取（690）所述液压系统参数值，并且如果所述液压系统参数值在所述液压系统参数范围之外，则根据减少的模式（692）操作所述液压变桨力系统（220），其中， 减少模式一个或多个基于音调的活动被减少（694）或暂停。 其优点可以是它能够在某些情况下保持风力涡轮机在生产中而不是关闭风力涡轮机。 在各方面中，还提供了计算机程序产品，桨距控制系统（250）和风力涡轮机（100）。

Abstract: The present invention relates to a method for operating a wind power facility during high- wind operations, the method comprising the steps of determining one or more operational parameters, and limiting one or more reactive power capabilities of the wind power facility to one or more predetermined reactive power values if at least one determined operational parameter differs from a predetermined value or a predetermined range. The one or more determined operational parameters may be a measured or estimated wind speed, or it may be based on at least a measured active power value and a measured generator speed. The present invention further relates to a wind power control module for carrying out the method.
