Abstract: The present disclosure is directed to a system for determining a torque exerted on a shaft of a wind turbine. The system includes a gearbox coupled to the shaft. The gearbox includes a first arm and a second arm. First and second fluid dampers respectively couple to the first and second arms of the gearbox. A first fluid conduit fluidly couples the first and second fluid dampers. A first pressure sensor is in operative association with the first fluid conduit to detect a fluid pressure of fluid within the first fluid conduit. A controller communicatively couples to the first pressure sensor. The controller is configured to determine the torque exerted on the shaft based on signals received from the first pressure sensor.

Abstract: The example systems, methods, and devices disclosed herein generally relate to performing predictive analytics on behalf of wind turbines. In some instances, a data-analytics platform defines and executes a predictive model for a specific wind turbine. The predictive model may be defined and executed based on operating data for the specific wind turbine and for other wind turbines that experience similar environmental conditions as the specific wind turbine and that are operating in an expected operational state. In response to executing the predictive model, the data-analytics platform may cause an action to occur at the specific wind turbine or cause a user interface to display a representation of the output of the executed model, among other possibilities.

Abstract: The present disclosure is directed to a system and method for stabilizing sub-synchronous interaction (SSI) of a wind turbine generator connected to a power grid. More specifically, the method includes measuring an alternating-current (a-c) quantity of the power grid. Another step includes converting the a-c quantity to a d-q quantity and providing the d-q quantity to a d-q control loop within the controller. Another step includes altering, with a symmetric control component, a transfer function of the d-q control loop. The method also includes generating at least one d-q reference signal for the wind turbine generator based on the altered transfer function so as to achieve symmetric control of the generator. A further step includes generating a control signal for the generator based, at least in part, on the at least one d-q reference signal. The method also includes operating the generator based on the control signal.

Abstract: A wind turbine (1) is provided, having a wind turbine tower (2) and at least one rotatable blade (5), and further comprising a system for measuring rotor blade vibration of said wind turbine. The system comprises at least one Doppler radar unit (7) operatively configured to emit and receive radar signals, the radar unit being mounted on the wind turbine tower at a position above the lowest position of the at least one blade, the radar unit being positioned so as to measure reflections of an emitted radar signal from the turbine blade. A processing unit is configured to receive measurement data from the radar unit and to determine, by analysis of Doppler shift in received radar signals relative to transmitted signals due to movement of the blade towards or away from the turbine tower, the velocity of the blade in the direction towards or away from the turbine tower. Using a radar unit to measure blade velocity allows a determination to be made of the vibrations occurring in the blade without needing an internal sensor in the blade. This reduces manufacturing and maintenance costs of the blades since sensors in the blades will not need to be replaced, and sensors positioned on the tower are easier to replace in the field.

Abstract: Embodiments of the invention generally relate to wind turbine generators, and more specifically to the deactivation of wind turbines in a wind turbine park. A wind park controller may be configured to retrieve data indicating fatigue experienced by each wind turbine of the wind turbine park, and deactivate those turbines determined to be the most fatigued, thereby increasing the lifetime of turbines in the wind turbine park.
