摘要： A method for monitoring the validity of a calibration of a system parameter is provided. A calibrated system parameter is generated based on the calibration by each of a plurality of spatially associated wind turbines of a wind park. The plurality of spatially associated wind turbines includes a first wind turbine and a second wind turbine. The method includes subtracting from a first signal representing the calibrated system parameter measured at the first wind turbine a second signal representing the calibrated system parameter measured by the second wind turbine in order to generate a difference signal, processing the difference signal by a function based on a stochastic model to generate a decision data signal and determining, based on the decision data signal, if the calibrated system parameter of at least one of the first wind turbine and the second wind turbine is based on an invalid calibration.

摘要： A rotary machine for a power system includes a rotary drum having a rotational center shaft, a stationary half gear including a generally circular non-geared portion and a geared portion having gear teeth, and at least one pair of revolving gears formed of two revolving gears symmetrically positioned about the center shaft and configured to simultaneously revolve around the stationary half gear. At least one rack shaft is operably coupled, directly or indirectly, to the revolving gears to reciprocate back and forth upon rotation of the revolving gears, and as the revolving gears revolve around the stationary half gear, one of the two revolving gears is configured to have gear engagement with the geared portion of the stationary half gear, while the other revolving gear is floating over the non-geared portion of the stationary half gear.

摘要： A method for operating a wind turbine for generating a settable turbine power, where the wind turbine includes a rotor having rotor blades adjustable in their blade angle, is operable at a settable rotor speed, and is installed at an installation site at a distance to an obstacle, comprises the obstacle causing a wind disturbance, which, in dependence on current wind direction and wind velocity, can reach the wind turbine as a wind wake, and the wind turbine reducing its turbine operation by throttling down for protection against loads due to the wind wake, wherein the throttling down is controlled in dependence on the current wind direction and the current wind velocity, wherein a weather prediction is used in order to take into consideration at least one further weather property in addition to the wind direction and wind velocity, and wherein the throttling down is additionally controlled in dependence on the weather prediction, in particular on the further weather property.

摘要： The present application discloses novel systems and methods for yawing an autonomous wind turbine. In an embodiment, the wind turbine includes a control system configured to determine a control action signal for a yaw drive mechanism of the wind turbine as a function of the wind condition(s) and as a function of the load condition(s). The control system is configured to monitor change(s) associated with the load condition(s) to determine if the load condition(s) is too high for too long, or in need of attention, before yawing of the wind turbine is initiated or, if the load condition(s) are getting too high, after yawing has been initiated. In another embodiment, the control system includes a load sensor system with proximity sensors arranged adjacent, on, and/or about the main shaft flange of the nacelle or on the rotor blades of the wind turbine.

摘要： The present disclosure relates to methods which comprise receiving a wind direction signal indicative of an instantaneous wind direction at a wind turbine, filtering the wind direction signal to determine a filtered wind direction signal and determining a yaw error signal of the wind turbine indicating a difference between a yaw angle of the wind turbine and the instantaneous wind direction indicated by the filtered wind direction signal. The methods furthermore comprise determining a control signal for a yaw system of the wind turbine based on the yaw error signal. Filtering the wind direction signal comprises applying a low pass filter with a variable time constant, wherein the variable time constant is dependent on a wind condition. The present disclosure further relates to control systems for wind turbines which are configured to implement such methods. The present disclosure further relates to methods of operating wind turbines.

摘要： The present disclosure is directed to a system and method for controlling and/or upgrading aftermarket multivendor wind turbines. The system includes a turbine controller configured to control operations of the wind turbine, a safety device configured to provide a signal indicative of a health status of the safety device, and a secondary controller inserted between the safety device and the turbine controller. The secondary controller is configured to receive the signal from the safety device over a communication interface. As such, if the signal indicates a normal health status, the secondary controller is configured to send the signal to the turbine controller, i.e. maintain normal operation. Alternatively, if the signal indicates a poor health status, the secondary controller is configured to adjust the signal based at least in part on a signal bias to an adjusted signal and to provide the adjusted signal to the turbine controller.
