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

chopper fed dc motor drive





INTRODUCTION

Development of high performance motor drives are very essential for industrial applications. A high performance motor drive system must have good dynamic speed command tracking and load regulating response. DC motors provide excellent control of speed for acceleration and deceleration. The power supply of a DC motor connects directly to the field of the motor which al ....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

A Novel VSI and CSI Fed Active-Reactive Induction Motor Drive with Sinusoidal Voltages and Currents


Abstract— Till date Load Commutated Inverter (LCI) fed synchronous motor drive configuration is popular in high power
applications(>10 MW). The leading power factor operation of synchronous motor by excitation control offers this simple and rugged
drive structure. On the contrary, LCI fed induction motor drive is absent as it always draws lagging power factor current. Therefo ....etc

DIRECT TORQUE CONTROL FOR MATRIX CONVERTER-FED THREE PHASE INDUCTION MOTOR WITH HYBRID PSO
ABSTRACT
Direct Torque Control (DTC) for Induction Motors using Matrix Converters is a high performance motor
control scheme with fast torque and flux responses. This paper presents a new control scheme based on
hybrid particle swarm optimization (HPSO). The main advantages of the matrix converter are combines
with those of the DTC technique, generating the required voltage vectors under 0.9 input power factor
operations. The results ....etc
