Control of variable speed wind turbines equipped with synchronous or doubly fed induction generators supplying islanded power systems
Abstract:
A control method for variable speed wind turbines (VSWTs) supplying islanded parts of electricalnetworks is presented. Active power/frequency and reactive power/voltage droops are applied in order todetermine the active, reactive power production, thus downscaling to the VSWTs the conventional controlconcepts of the power plants. Two types of VSWTs comprising doubly fed induction gene ....etc

Most of the gas turbines employ the axial flow turbines.

The article is concerned with axial flow turbines.

The radial turbine can handle low mass flows more efficiently than the axial flow machines.

Elementary Theory of Axial Flow Turbine:
The velocity triangles for one axial flow turbine stage and the nomenclature employed are shown. The gas enters the row of nozzle blades with a static pressure and temperature P1, T1, and a velocity C1, is expanded to P2, T2, with an increased velocity C2 at an angle Alpha2

INTRODUCTION

Renewable energy is energy which comes from natural resources such as sunlight, wind, rain, tides, and geothermal heat, which are renewable.

Climate change concerns, high oil prices, and increasing government support, accelerates the growth of this sector.

In 2008, about 19% of global final energy consumption came from renewable sources.

With nations pledging to reduce the carbon emiss ....etc

A Study of Vertical Axis Wind Turbines



Introduction:

As we all know, the demand for energy is increasing exponentially as more and more people inhabit this earth. At the same time, the energy source that met all of our needs in the past decades, non-renewable in nature, seems to decrease in equal pace leaving us at the door steps of renewable energy sources for help as we go forward in our journey in to the future. Due to this inevitable need, many scientists and researchers are turning back to the essent ....etc

ABSTRACT
This paper deals with wind power generation and the limitations that arise in generation. As energy crisis is very high in case of developing countries like India, there came urgent need to look for other sources of energy that are clean and pollution free as conventional sources causes pollution. Wind is a clean and plentiful source of energy. The wind is a non-conventional source similar to Solar, Sea, Geothermal and Biomass. A Windmill utilizes the wind energy an ....etc

abstract
This work presents the development of a simple analytical model of performance for heavy duty gas turbine
combustors and its use for the analysis of main emissions for a set of syngas fuels. This set of syngas fuels has
been selected as a wide representation of different compositions of syngas fuels, from fossil or vegetal
origins. Their combustion processes have been modelled as a set of chemical reactors in serial and a detailed
kinetic model, simulating a conventional diffusion flame combustor. In each slice, the thermo ....etc
