System and method for adjusting a bending moment of a shaft in a wind turbine

摘要

A system (100) and method for adjusting a bending moment of a shaft (50) in a wind turbine (10) are disclosed. The system (100) includes a pillow block (66) accepting the shaft (50) therethrough, a sensor (102) mounted to the pillow block (66) and measuring deformation of the pillow block (66), and a control system (36) communicatively coupled to the sensor (102). The control system (36) is configured to adjust a rotor blade (22) in response to the deformation of the pillow block (66). The method includes measuring a deformation of a pillow block (66), and adjusting a rotor blade (22) in response to the deformation of the pillow block (66). The pillow block (66) accepts the shaft (50) therethrough.
