Abstract: The invention relates to a decision support system (DSS, 1) for maintenance of renewable energy generators, such as wind turbine generator (WTG, 11). A forecasting module (FM, 21) outputs renewable power plant relevant parameters (PF) in a prediction window of time (TW), whereas an optimization module (OPT, 22) receives the relevant parameters (PF), and proposes a maintenance schedule (PROP-MAN) for the renewable power plant (WPP) in order to optimize the produced energy with respect to the demand in said predefined prediction window (TW). A renewable energy generator condition module (WT-CON, 23) outputs condition data into maintenance recommendations (REC-MAN) for one or more renewable energy generators. Finally, a renewable energy generator maintenance recommendation module (WTM, 24) is arranged to combine the proposed maintenance schedule and the maintenance recommendations into a final maintenance decision proposal (FIN-PROP-MAN). The invention changes the traditional concept of reactive and predictive maintenance technique for renewable energy generators, such as wind turbine generators.

Abstract: The present invention relates to a method of controlling a wind turbine having at least one blade and a controller, including: detect location of foreign material adhered to the blade by sensors mounted on the blade and communicatively coupled to the controller; determine the resonance mode of the blade to be excited based on the location of the foreign material by the controller; and excite the blade to the resonance mode; wherein the resonance mode is one higher than the first order resonance mode. The present invention also relates to a wind turbine using the method.

Abstract: A wind turbine blade ice accretion detector 65 is configured to receive an indication of power generated by a wind turbine 67 and an indication of a plurality of environmental conditions of the wind turbine 69. It is also configured to receive an indication of an error relating to the operation of the wind turbine 71. These indications are processed by the detector 65 to provide an indication of ice accretion of a wind turbine blade. In addition to or as an alternative, the wind turbine blade ice accretion detector 65 is configured to receive an indication of power generated by a wind turbine 67 in a plurality of different time periods and an indication of a plurality of environmental conditions of the wind turbine 69 in the plurality of different time periods; and to process these to provide an indication of ice accretion of a wind turbine blade.
