Dong, J. (author), Viré, A.C. (author), Ferreira, Carlos (author), Li, Zhangrui (author), van Bussel, G.J.W. (author)A modified free-wake vortex ring model is proposed to compute the dynamics of a floating horizontal-axis wind turbine, which is divided into two parts. The near wake model uses a blade bound vortex model and trailed vortex model, which is developed based on vortex filament method with straight lifting lines assumption. By contrast, the far...journal article 2019

Shipurkar, U. (author), Lyrakis, E. (author), Ma, Ke (author), Polinder, H. (author), Ferreira, Jan Abraham (author)The power electronic converter, especially the power semiconductor, is a major contributor to the failure rates of the wind turbine drivetrain. As the temperature is a major driving factor behind the failure mechanisms of these power semiconductors the choice of topology and switching strategy can have a significant effect on the reliability...journal article 2018

Shipurkar, U. (author), Polinder, H. (author), Ferreira, Jan Abraham (author)Availability is an important factor to be considered when designing wind turbine generator systems. The quest for increasing availability is based on the following five design approaches - design for component reliability, active control for reliability, design for fault tolerance, prognostics, and design for maintainability. This paper reviews...journal article 2016
