Abstract: A diagnostic system for use in a wind turbine yaw system, comprising: a tower motion sensor configured to output a signal indicative of tower oscillation, in particular though not exclusively side to side tower oscillation, and a diagnostic module configured to: analyse the tower motion sensor signal to identify frequency content of the signal that is not associated with the tower oscillation; and correlate the identified frequency content with the operation of the yaw system thereby to determine that the yaw system requires maintenance. Beneficially the invention provides that the health of the yaw system can be determined by analysing the oscillatory movement of the tower as measured by a tower motion sensor installed at a suitable location for example at the top of the tower or in the nacelle for example.

Abstract: A sensor system for a wind turbine, comprising: a blade load sensor; a blade temperature sensor configured to provide a temperature measurement of an associated blade; a load calculation module configured to output a temperature-corrected blade load value; and a processing unit interfaced with the temperature sensor. The processing unit includes a temperature estimator configured to determine an estimated temperature of the wind turbine blade based on at least one wind turbine parameter; and a comparator configured to generate a fault signal based on a comparison between the blade temperature measurement and the estimated blade temperature. The invention also resides in a corresponding method.

Abstract: The present invention refers to a method for operating a wind turbine, the wind turbine particularly comprising a tower and a rotor with rotor blades. The pitch angles of the rotor blades are adjusted to generate a force on the rotor and the tower. The force is adjusted to counteract and damp an oscillation. The adjustment is enabled by an activation decision unit, if the activation decision unit decides that certain parameters characterising the oscillation or loads of the tower indicate a requirement and/or if the activation decision unit determines that the generated force is sufficient to counteract an oscillation of the tower. In various embodiments the parameters characterising the oscillation or loads of the tower comprise current oscillations and their amplitude, an estimate of loads incurred in the turbine structure, an estimate whether damping in the near future might become necessary, an indication whether a different oscillation damping algorithm than individual blade pitch control is currently performing, and an indication whether a wind speed is above a certain portion of a rated wind speed.

Abstract: The invention relates to a control apparatus and method for controlling the rotor blades of a wind turbine, and in particular to controlling the rotor blades during an extreme wind event. An extended mode of operation of the wind turbine rotor beyond the cut-out wind speed is provided. In the extended mode of operation, the pitch of the wind turbine blades is actively controlled so that the rotor and the generator idle at a designated rotational speed. The rotational speed may be relatively high, say 15 to 20% of the nominal speed, compared with minimal speeds experienced by purely feathered wind turbine blades, and may be further controlled as a function of the incident wind speed. Output power control in the extended mode may be zero but is preferably a low, but non-zero value. The output power so produced may then be used as an auxiliary power source for controlling the wind turbine in situations where the utility grid fails.

Abstract: A method of controlling a wind turbine is described. The method involves forecasting the temperature evolution of a component of the wind turbine based upon the current operating parameters of the wind turbine and upon a required power output; predicting from the temperature forecast a future alarm event caused by the temperature of the component exceeding a first threshold level or falling below a second threshold level; and adjusting the operating parameters of the wind turbine to control the temperature evolution of the component thereby to avoid or delay the predicted alarm event.
