DVC strategy with MPPT for a DFIG-based SeaFlow variable-speed marine current turbine

Revue des Énergies Renouvelables
The integration of marine current turbines is a keystone of the global race toward renewable energy, and tidal currents, in particular, offer higher predictability and energy density, providing a reliable source of clean power.

Overview of HVRT technical measures for DFIG

IOP Conference Series: Earth and Environmental Science, 2017
A With the rapid increase of the proportion of double-fed induction wind turbines generator (DFIG), higher requirements are proposed for the continuous operation ability under external power grid failure. The paper first analysed the transient process of DFIG in cases of power grid voltage surge, proposed the related standard requirements for high ...

Study on Fault Current of DFIG during Slight Fault Condition [PDF]

, 2013
In order to ensure the safety of DFIG when severe fault happens, crowbar protection is adopted. But during slight fault condition, the crowbar protection will not trip, and the DFIG is still excited by AC-DC-AC converter.

A novel hybrid interlinking transformer-integrated DFIG wind power and energy storage system with flexible control strategy

International Journal of Electrical Power & Energy Systems
Double-fed induction generator (DFIG) based wind turbine generator (WTG) demonstrates pronounced sensitivity to the abnormal grid voltages, such as sag, swell or harmonic, which can precipitate disconnections from the power grid due to fault ride-through

Grid Voltage Unbalance and The Integration of DFIG’s

, 2013
Double-fed induction generators (DFIG’s) became the predominant generator installed for wind generation applications in the mid 1990’s. Issues pertaining to the operation and control of DFIG’s subsequently became apparent, particularly in weak areas of the grid network.
