摘要： A system for identifying the likelihood of a wind turbine rotor blade striking a wind turbine tower comprises a device for sensing bending of a wind turbine rotor blade and a device for sensing bending of a wind turbine tower. In a preferred embodiment Long Period Grating (LPG) sensors are used to measure bending of the tower. Preferably a plurality of LPG sensors is provided along the length of the blade. In one embodiment at least one of the LPG sensors comprises two sensing elements arranged to sense in perpendicular directions. In another embodiment a plurality of LPG sensors are provided each on different sides of the wind turbine tower. A processor uses the sensed blade and tower bending to determine whether the distance between the blade and the tower will be below a predetermined minimum value. If the distance is determined to be below the predetermined minimum value a controller may be used to adjust a wind turbine variable to reduce loading on the blade and thereby reduce the likelihood of a tower strike.

摘要： The invention relates to a method for detecting icing and other loadings on blades of wind turbines. Advantageously, the method utilizes existing wind turbine actuators, for example pitch actuators, far excitation of blade vibrations. Vibration sensors on the blade such as strain sensors or accelerometers measure the blade vibrations excited in response to the actively excised vibrations. By comparing the measured response with previously obtained reference responses, it is possible to determine if blade icing is present.

摘要： An energy extraction device and method for extracting energy from a fluctuating energy flow from a renewable energy source. A hydraulic pump is driven by a rotating shaft, driven in turn by a renewable energy source. A hydraulic motor drives a load and a high pressure manifold communicates between the pump, motor and an elastically deformable fluid retaining body. The hydraulic pump and hydraulic motor comprise working chambers displacing a volume of working fluid selectable on each cycle of working chamber volume by the control of electronic valves. The pressure in the high pressure manifold is measured and the net rate of displacement of working fluid by the hydraulic pump is selected responsive thereto to regulate the torgue applied to the said rotating shaft. The net rate of displacement of working fluid by the hydraulic motor is selected to smooth the energy flow to the load. The net rate of displacement of working fluid by the hydraulic motor is selected to cause the pressure within the high pressure manifold to tend towards an optimum. The optimum is variable and can be selected to optimise the efficiency of power transmission from the rotating shaft to the load or to increase the longevity of the energy extraction device.

摘要： A speed/torque enhancing power transmission is disclosed that translates slow rotating, high torque motion to high rotation, low torque motion or alternatively high rotating low torque motion to low rotating high torque motion and is suitable as a speed increaser for use in a device like a wind turbine. As a speed increaser the transmission has certain advantages, such as reduced weight and/or size compared to other units having the same performance characteristics. The speed increaser employs an externally toothed spur gear orbiting in a non-rotating manner inside an internally toothed ring gear. The input drives the ring gear and the orbiting spur gear drives an eccentric on the output shaft. In one embodiment, cross guide projections on the spur gear and cross guide projections on the housing engage slots in a swash plate.

摘要： The risk of an extreme gust of wind hitting a wind turbine is estimated by gathering data from one or more sensors for use as training data. This data is acquired over a period of time and is converted in to a feature vector for a given time period by a statistical measure. A number of feature zones are formed, each zone relating to a different estimate of risk with each feature vector being assigned to a risk category. The risk category is defined with reference to the value of one or more chosen turbine parameters at the time the data was acquired. The feature zones are formed from from a measure of distance such as the mean and covariance of feature vectors from within a given category. Live data is processed by measuring the mahalonobis distance from the feature vector of the live data to the centre of each zone and the risk of an extreme gust is assessed as that of the feature zone to which the mahalonobis distance is lowest.

摘要： A wind turbine power generating system includes a wind turbine connected to a speed increasing gearbox having an output shaft. An electrical generator having an input shaft is also provided. An asymmetrical coupling interconnects the input and output shafts. The coupling includes a first torque limiting clutch in series connection with a one-way clutch between the input and output shafts. A second torque limiting clutch is provided in parallel connection with the one-way clutch between the input and output shafts. The first and second torque limiting clutches have different characteristic slip torques. The interconnection of the clutches, and the implementation of the one-way clutch, provides for effective operation of the first and second torque limiting clutches in opposite rotational directions of the input and output shafts. The second torque limiting clutch has a characteristic slip torque that is a fraction of the first torque limiting clutch, the second torque limiting clutch providing protection against reverse impulse loads.
