Abstract
There is provided a method for controlling a hydraulic pitch force system () so as to reduce or eliminate a decrease in hydraulic oil pressure () if a hydraulic system parameter value is outside a hydraulic system parameter range, the method comprising: Obtaining () the hydraulic system parameter value, and operating the hydraulic pitch force system () according to a reduced mode () 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 () 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 () and a wind turbine ().
