Abstract: A method of transitioning a wind turbine from a sleep state is provided in which a wind speed at the wind turbine is measured, and the measured wind speed is compared to a wake-up threshold. If the wind speed exceeds the wake-up threshold, the wind turbine is transitioned to an active state. Before comparing, either the measured wind speed or the wake-up threshold is adjusted based on an outcome of at least one previous transition from the sleep state of the wind turbine.

Abstract: The invention provides a method of determining tower top acceleration of a wind turbine. The method includes receiving acceleration data from a plurality of acceleration sensors positioned in a nacelle of the wind turbine, including data indicative of a measured acceleration in a direction along at least one measurement axis of each respective acceleration sensor at a current time step. The method includes determining a predicted tower top acceleration of the wind turbine tower at the current time step, the predicted tower top acceleration being determined in dependence on a kinematic model of the wind turbine, and on a determined estimation of tower top acceleration at a previous time step. The method includes determining an estimated tower top acceleration of the wind turbine tower at the current time step by updating the predicted tower top acceleration based on the measured acceleration from each of the acceleration sensors.

Abstract: Methods and systems for recycling a printed circuit board (PCB). The printed circuit board is exposed to a swelling agent that causes an epoxy matrix of the printed circuit board to swell and disintegrate into particles. The particles of epoxy are then separated from the printed circuit board, leaving behind reinforcing fiber and metal containing components thereof. These remaining components are separated from each other and recycled separately using suitable processes. The epoxy particles are also recovered, and may be reduced to a monomer for use in synthesizing new epoxy. The swelling agent includes a carboxylic acid, preferably formic acid, as an active ingredient.

Abstract: A main bearing housing for supporting a main rotor shaft of a wind turbine, wherein the main bearing housing defines a first end, a second end and a floor region intermediate the first and second ends. The main bearing housing comprises a first bearing arrangement positioned at the first end of the main bearing housing, a second bearing arrangement positioned at the second end of the main bearing housing, wherein the floor region includes a first oil sump positioned at the first bearing arrangement, and a second sump positioned at the second bearing arrangement. Advantageously, the embodiments of the invention provide that the bearings of the main bearing housing are lubricated by a lubrication system that includes sumps positioned at each of the fore and aft bearings of the main rotor shaft. The fore and aft bearings are therefore supplied with oil at suitable lubrication points and are part of the lubrication system that supplies oil to other components in the wind turbine that require oil lubrication, for example the gearbox and/or the generator bearings. The fore and aft bearings of the main bearing housing therefore do not require a separate lubrication system, such as a grease-based system and so the overall lubrication requirements for the nacelle are simplified.

Abstract: A method is provided for controlling power oscillations at a point of common coupling in a wind park. Individual power reference offsets defining an adjustment to a wind turbine power reference signal for counteracting mechanical oscillations in the respective wind turbines are received from respective wind turbine controllers. Based on an aggregated power reference offset, a total power oscillation compensation signal is determined. Individual power oscillation compensation signals for adjusting the wind turbine power reference signal of respective wind turbines are determined based on the individual power reference offsets and the total power oscillation compensation signal. These individual power oscillation compensation signals are then sent to the respective wind turbines.

Abstract: A wind turbine comprising, a tower, a nacelle mounted on the tower, and a rotor defining a rotor axis extending in a vertical center plane and configured for harvesting wind energy by rotation of blades in a rotor rotation direction about the rotor axis. The nacelle comprises a rotor-supporting assembly forming a load path from the rotor to the tower and configured for receiving rotor torque caused by the rotation of the rotor. To reduce loading of the tower and potentially provide a cheaper construction, the nacelle has a center of gravity which is offset from the center plane in a direction relative to the rotor rotation direction to counteract the rotor torque.

Abstract: The present invention relates to controlling a wind turbine with an updated power coefficient. The updated power coefficient being adjusted by a degradation function which is determined in an iterative adjustment process. The wind turbine is controlled in partial load operation mode based on a tip-speed ratio (TSR) tracking scheme based on an estimated wind speed. The iterative adjustment process comprises operating the wind turbine to obtain a measurement set. The degradation function that represents the values of the measurement set is calculated and assigned to the mean operating TSR of the measurement set. The iterative process is continued until a difference between the selected TSR and the mean operating TSR is below a preset difference. A continuous degradation function for a range of the mean operating TSR value(s) is thereby obtained to determine an updated power coefficient to be used as the operating power coefficient.

Abstract: A method of retrofitting a wind turbine having a tower and a first energy generating unit with a second energy generating unit. The method includes analyzing a first natural frequency of the tower relative to first rated operation frequencies of the tower having the second energy generating unit; when the first natural frequency lies within the first rated operation frequencies, modifying one or both the tower and the second energy generating unit so that the modified one or both the tower and the second energy generating unit have a second natural frequency and second rated operation frequencies that do not overlap; and replacing the first energy generating unit with the second energy generating unit.
