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.

IMC robust control for high‐voltage ride‐through of doubly fed induction wind generator
IEEJ Transactions on Electrical and Electronic Engineering, 2018To solve system parameter variation such as magnetic circuit saturation and excitation inductance of the doubly fed induction generator (DFIG) caused by grid voltage swells, a high‐voltage ride‐through (HVRT) robust control method for the DFIG based on the internal model control (IMC) controller is proposed.

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

2011 IEEE PES Innovative Smart Grid Technologies, 2011
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

Improvement of High-Voltage-Ride-Through Capability of DFIG Based Wind Turbines with D-STATCOM
Applied Mechanics and Materials, 2013Along with the increasing of wind power penetration in the grid, much attention has been paid to the high voltage ride through (HVRT) capability of double fed induction generator (DFIG) based wind parks. To regulate the reactive power dynamically, the distribution static synchronous compensator (D-STATCOM) has been considered to be a valid method.

Low Voltage Ride-Through of high power DFIG wind turbine using three-level NPC converters
2009 35th Annual Conference of IEEE Industrial Electronics, 2009Nowadays, there is a tendency to increase the power of wind turbines. Multilevel converter is a realistic alternative in such high power applications. As the most widely used variably speed wind turbine, doubly fed induction generators (DFIG) are very sensitive to grid disturbances.
