System and method for determining torque on a wind turbine shaft

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.
