20120139242 | SYSTEM AND METHOD FOR ADJUSTING A BENDING MOMENT OF A SHAFT IN A WIND TURBINE - A system and method for adjusting a bending moment of a shaft in a wind turbine are disclosed. The system includes a pillow block accepting the shaft therethrough, a sensor mounted to the pillow block and measuring deformation of the pillow block, and a control system communicatively coupled to the sensor. The control system is configured to adjust a rotor blade in response to the deformation of the pillow block. The method includes measuring a deformation of a pillow block, and adjusting a rotor blade in response to the deformation of the pillow block. The pillow block accepts the shaft therethrough. | 06-07-2012 |
20140056705 | LOAD CONTROL SYSTEM AND METHOD FOR WIND TURBINE - A load control system for a wind turbine and a method for controlling wind turbine loading are provided. The system includes a sensor assembly. The sensor assembly includes a light source mounted to a rotor shaft and configured to emit a light, and a sensor mounted to the rotor shaft and configured to sense the light and measure a location of the light in a plane perpendicular to a longitudinal axis. The system further includes a controller communicatively coupled to the sensor assembly. | 02-27-2014 |
20150069762 | SYSTEM AND METHOD FOR MONITORING WIND TURBINE LOADING - Systems and methods for monitoring wind turbine loading are provided. In one embodiment, a system includes a main shaft, a bedplate, and a gearbox coupled to the main shaft and mounted to the bedplate. The gearbox includes an outer casing and a torque arm extending from the outer casing. The system further includes an isolation mount coupled to the torque arm, and a sensor configured to measure displacement of the torque arm. In another embodiment, a method includes operating the wind turbine, and detecting displacement of a torque arm of a gearbox of the wind turbine. The method further includes calculating a moment for a main shaft of the wind turbine based on the displacement of the torque arm. | 03-12-2015 |
