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
causes of decreased efficiency ....etc

DOUBLY FED INDUCTION MACHINE

INTRODUCTION
ELECTRICAL MACHINES
Based on the supply, 2 types-AC machine & DC machine
AC machines are of different types
1. Induction machine
2. Synchronous machine etc.

INDUCTION MACHINE
Induction machines are of different types and one of the type in particular are Singly Fed and Doubly Fed.
SINGLY FED INDUCTION MACHINE
1. Only ONE winding active in ENERGY conversion Process
2. Can have speed around Synchronous Speed.

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 the ....etc

Wind what causes it?, cont.
Pressure differences cause the flow of fluids (gases and liquids)
pressure is always measured relative to some reference pressure
Sometimes relative to vacuum absolute
Sometimes relative to atmospheric pressure
