This paper proposes the dynamic voltage and current assignment (DVCA) strategies for doubly fed induction generator (DFIG) wind power system, which is fed by nine-switch converter (NSC). With the proposed DVCA strategies, the voltage and current capacities of switches in NSC are dynamically assigned to the rotor- and grid-side branches, depending on ...

Effect of low voltage ride through (LVRT) characteristic on voltage stability
IEEE Power Engineering Society General Meeting, 2005, 2005The number of wind installations has grown worldwide at unprecedented rates in recent years. As well, the average size of the installations has increased due to the advent of larger capacity machine, variable speed technology, and an increasing number of off-shore sites.

Low Voltage Ride through (LVRT) Control of Double-Fed Wind-Driven Generator
Advanced Materials Research, 2012With 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

2013 IEEE Energy Conversion Congress and Exposition, 2013
This paper has an experimental discussion on low-voltage-ride-through (LVRT) capability of a phase-shifted-PWM STATCOM using the modular multilevel cascade converter based on single-star bridge-cells (MMCC-SSBC). The cluster-balancing control, that produces a significant effect on the LVRT capability, is modeled and analyzed with focus on either low ...
