Abstract
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.
