ENHANCED PERFORMANCE OF A DOUBLY FED
WIND-POWER INDUCTION GENERATOR AT WIND-
RANGE BOUNDARIES
ABSTRACT
The doubly fed induction generator (DFIG) is one of the largest generators used
with MW-class wind turbines. This paper focuses on the weak performance areas
of grid-connected DFIG-based wind turbines. Basically, the DFIG performance at
low wind speeds, close to the cut in speed, and around the full rating operation (in
the vicinity of rated wind speed) is investigated. For low wind speed region, the

Doubly-Fed Induction Generator for Variable Speed Wind Energy Conversion Systems- Modeling & Simulation
Abstract— The aim of this paper is to present the complete modeling and simulation of wind turbine driven doubly-fed induction generator which feeds ac power to the utility grid. For that, two pulse width modulated voltage source converters are connected back to back between the rotor terminals and utility grid via common dc link. The grid side converter controls the power flow between the DC bus and the AC side and allows t ....etc

Control of variable speed wind turbines equipped with synchronous or doubly fed induction generators supplying islanded power systems
Abstract:
A control method for variable speed wind turbines (VSWTs) supplying islanded parts of electricalnetworks is presented. Active power/frequency and reactive power/voltage droops are applied in order todetermine the active, reactive power production, thus downscaling to the VSWTs the conventional controlconcepts of the power plants. Two types of VSWTs comprising doubly fed induction gene ....etc
