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

NON CONVENTIONAL ENERGY SOURCES
Abstract
The ever increasing rapid use of the fossile fuels day by day has threatened exhausting of conventional energy sources very soon. Also the use of conventional energy sources has increased the global pollution level which is resulting in climate change. Therefore time has come for searching altogether other sources of energy which are inexhaustible and gradually replace the conventional sources. The non conventional energy sources such as solar, wind, tidal, oce ....etc

The Switched Reluctance Generator for Wind Power Conversion

The use of wind energy has become increasingly important as a renewable energy source, so there is an increasing interest in exploiting it using a Switched Reluctance Machine (SRM).

Introduction

In the last decades, the SRM serves as an important alternative in various applications both within the industrial and domestic markets, as a motor showing good mechanical reliability, high torque-volume ratio and high efficiency,and it is of low cost.Eventhough SRM is easy to build ....etc

more about maximum power tracking control of wind energy conversion system using matrixconverter

Abstract

This paper focuses on maximum wind power extraction for a wind energy conversion system composed of a wind turbine, a squirrel-cage induction generator, and a matrix converter. At a given wind velocity, the mechanical power available from a wind turbine is a function of its shaft speed. In order to track maximum power, the matrix converter (MC) adjusts the induction generator terminal frequency, and thus, the turbine shaft speed. The ....etc

The modeling and simulation of a grid-connected wind power system or WECS (acronym for Wind Energy Conversion System) has been carried out. Our goal is to design and test a power system of 14.9 KVA capacity, operating at 440V, 20m / s wind speed base, induction generator based on wind power system through. MATLAB simulation. The various components of a wind power system, namely wind turbine, generator, control system, rectifier-inverter, battery, load and other equipment, including transformers, network, etc., were Decided according to the scop ....etc

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

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
