Hybrid high-power rectifier with reduced THDI and voltage sag ride-through capability
2011 IEEE Industry Applications Society Annual Meeting, 2011Temporary voltage sags are the main cause of untimely arrest in automated systems that use adjustable speed drives (ASDs). In this context, this paper presents an analysis of a new hybrid three-phase rectifier designed to correct the power factor and to promote voltage sag ride-through capability to ASDs.

High voltage ride-through control strategy of grid-side converter for DFIG-based WECS
IECON 2013 - 39th Annual Conference of the IEEE Industrial Electronics Society, 2013For doubly-fed induction generator (DFIG)-based wind energy conversion system (WECS), grid voltage swell is harmful to the dc-link capacitor and the grid-side converter (GSC). The grid over-voltage may lead to the reversal of power flow in the GSC, resulting in the uncontrollability of the GSC. In order to handle this situation, the control strategy of

The amount of wind turbine connected to the power grid has significantly increased during the last decade. This has resulted in essential need to establish grid codes. Previously, wind turbine generators (WTGs) were allowed to be disconnected from the network during any disturbance at the grid side to avoid WTGs from being damaged. However, lately, the
