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.

Field Orientated Control of a Multi-Level PWM Inverter Fed Induction Motorr
abstract
This thesis presents the simulation of a Field Orientated Control of a Multi level PWM Inverter fed induction motor system and its implementation in terms of programming and code in a real time operating system. Field Orientated Control allows precise controllability and excellent transient behaviour when used to control an induction motor by manipulating the angle and amplitude of the torque and speed producing curren ....etc

Modeling and Simulation of Speed of a Doubly Fed Induction Motor with Different Regulators
Many industrial applications require new control techniques in order to obtain fast response and to improve the dynamic performances. One of the techniques users, sliding mode,fuzzy logic and fuzzy sliding mode control which are characterizes by robustness and insensitivity to the parameters variation. In this paper, we present a comparative study of a direct stator flux orientation control of doubly fed induction motor ....etc

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
