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 d ....etc

Fuzzy Logic Control of Doubly Fed Induction Generator Wind Turbine



INTRODUCTION

Wind energy is one of the extra ordinary sources
of renewable energy due to its clean character and
free availability. Moreover, because of reducing the
cost and improving techniques, the growth of wind
energy in Distributed Generation (DG) units has
developed rapidly
In terms of wind power generation technology,
because of numerous technical benefits (higher energy

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 decreas ....etc

DOUBLY FED INDUCTION GENERATOR IN A WIND TURBINE

1 INTRODUCTION
In a wind power generating system, it is required that the
generator tracks a prescribed torque-speed profile. Variablespeed
operation is introduced to gain high efficiency in the
generating system. Otherwise the generating system cannot
capture the largest possible energy available from the wind and
the blades of the wind turbine will subject to torsional stress
and windage friction.
The mechanical efficiency in a wind turbine is dependen ....etc

DIRECT TORQUE CONTROL OF DOUBLY FED INDUCTION GENERATOR BASED WIND TURBINE UNDER VOLTAGE DIPS



ABSTRACT

This paper focuses the analysis on the control of doubly fed induction generator (DFIG) based high-power wind
turbines when they operate under presence of voltage dips. The main objective of the control strategy proposed
for doubly fed induction generator based wind turbines is to eliminate the necessity of the crowbar protection
when low-depth voltage dips occu ....etc

DIRECT TORQUE CONTROL FOR DOUBLY FED INDUCTION MACHINE-BASED WIND TURBINES UNDER VOLTAGES DIPS AND WITHOUT CROWBAR PROTECTION



Abstract

This letter proposes a rotor flux amplitude reference generation strategy for doubly fed induction machine based wind
turbines. It is specially designed to address perturbations, such as voltage dips, keeping controlled the torque of the wind turbine,
and considerably reducing the stator and rotor over currents during ....etc
