Systems And Methods For Determining Deflection Of A Wind Turbine Shaft

Abstract: A system (200,300) for determining deflection in a shaft (134) of a wind turbine (100), the wind turbine having a plurality of rotor blades (112) extending from a hub (110) coupled to the shaft is provided. The system includes an emitter (164) positioned adjacent a first portion of the shaft, the emitter configured to emit a light beam, a receiver (168) positioned adjacent a second portion of the shaft, the receiver configured to receive the light beam emitted from the emitter and determine a location where the light beam strikes the receiver, and a controller communicatively coupled to the receiver, the controller configured for determining deflection of the shaft based on the location on the receiver where the light beam strikes the receiver.
