Pressure
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

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
c ....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

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
