Wind Turbine Condition Monitoring: State-of-the-Art Review, New Trends, and Future Challenges
Pierre Tchakoua,Rene Wamkeue,Mohand Ouhrouche,Fouad Slaoui-Hasnaoui,Tommy Andy Tameghe,Gabriel Ekemb +5 more
TL;DR: In this article, a general review and classification of wind turbine condition monitoring methods and techniques with a focus on trends and future challenges is provided, and interesting insights from this research are used to point out strengths and weaknesses in today's WTCM industry and define research priorities needed for the industry to meet the challenges in wind industry technological evolution and market growth.
Prediction of Mechanical Shaft Failures Due to Pulsating Torques of Variable-Frequency Drives
TL;DR: In this paper, the effects of mechanical damping on the motor air-gap torque have been analyzed and the effect of variable frequency drive incorporated in a rotating shaft is shown to be one of the main root causes of mechanical shaft failures.

Decoupling Network of Field-Oriented Control in Variable-Frequency Drives
TL;DR: A novel decoupling current control method is proposed to consider the coupling terms of both the motor and power converter in a synchronous current controller and shows good performance, and the d-axis current is always separated from the q-axisCurrent during variation of the mechanical load.
