Systematic development of Low Voltage Ride-Through (LVRT) envelope for grids

TENCON 2010 - 2010 IEEE Region 10 Conference, 2010
Increased penetration of wind generation into high voltage transmission systems necessitates development of grid integration standards. One of them is Fault Ride-Through (FRT) or Low Voltage Ride-Through (LVRT) guidelines. Development of the voltage envelope depends on the transmission network characteristics along with considerations like contingency ...

Low Voltage Ride through (LVRT) Control of Double-Fed Wind-Driven Generator

Advanced Materials Research, 2012
With the rapid development of the wind power, it is no longer an isolated power system and gradually incorporated in the local power grid. However, as the increasing proportion of the installed wind power capacity in the power grid, the affection of the wind turbine to the region power system is getting heavier, which inevitably bring some new problems

Low-Voltage-Ride-Through (LVRT) Control of an HVDC Transmission System Using Two Modular Multilevel DSCC Converters

IEEE Transactions on Power Electronics, 2017
This paper presents an intensive discussion on a high-voltage direct-current (HVDC) long-distance transmission system combining two modular multilevel double-star chopper-cells (DSCC) converters with dc power cables. Hereinafter, each converter is referred to simply as a DSCC converter, or just as a DSCC for more simplicity.
