Enhancing the HVRT and LVRT Capabilities of DFIG-based Wind Turbine in an Islanded Microgrid [PDF]
Engineering, Technology & Applied Science Research, 2017 Doubly fed induction generator (DFIG) based wind turbines are very sensitive to grid voltage variations. Therefore, low-voltage-ride-through (LVRT) and high-voltage-ride-through (HVRT) capabilities are employed to improve DFIG performance during grid faults and voltage swell events. In this paper, a superconducting magnetic energy storage (SMES) device

LVRT and HVRT control strategies of doubly- fed induction generator [PDF]
, 2018 The Doubly Fed Induction Generator (DFIG) has a high sensitivity to the Grid Faults (GFs), which can cause many problems on the power quality and the production continuity. Actually, the grid connection requirements impose strict laws to respect to Low Voltage Ride Through (LVRT), High Voltage Ride Through (HVRT), and grid support capacities following ...

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 ...
