A multilevel modular converter for a large, lightweight wind turbine generator (2008)
Journal Article
Ng, C., Parker, M., Ran, L., Tavner, P., Bumby, J., & Spooner, E. (2008). A multilevel modular converter for a large, lightweight wind turbine generator. IEEE Transactions on Power Electronics, 23(3), 1062-1074. https://doi.org/10.1109/tpel.2008.921191

In an onshore horizontal axis wind turbine, generator and converter are usually in the nacelle on the top of the tower, while the grid step-up transformer is placed at the bottom. Electric power is transmitted down through flexible cables of high cur... Read More about A multilevel modular converter for a large, lightweight wind turbine generator.

Control of a Doubly Fed Induction Generator in a Wind Turbine During Grid Fault Ride-Through (2006)
Journal Article
Xiang, D., Ran, L., Tavner, P., & Yang, S. (2006). Control of a Doubly Fed Induction Generator in a Wind Turbine During Grid Fault Ride-Through. IEEE Transactions on Energy Conversion, 21(3), 652-662. https://doi.org/10.1109/tec.2006.875783

This paper analyzes the ability of a doubly fed induction generator (DFIG) in a wind turbine to ride through a grid fault and the limitations to its performance. The fundamental difficulty for the DFIG in ride-through is the electromotive force (EMF)...
