Abstract :
This paper presents an approach to detect and estimate drop of gearbox efficiency in wind turbine systems. First, shaft torque is estimated through a specified model. The last estimation torque is used to detect gearbox efficiency drop through a proportional action loop. The approach was implemented on FAST coded simulator, designed by the US National Renewable Energy Laboratory´s National Wind Turbine Center. The obtained results provide a good fault detection and estimation.
