Abstract

The focus of this paper is to study the asynchronous generator (generator of squirrel-cage induction), as an alternative distributed generation technology, in particular the driving of machines using methane gas from pig farms as their fuel. Pig farming has grown dramatically over recent years. This agro-industrial activity produces huge quantities of methane gas which is released into the atmosphere depleting the ozone layer, in addition to contributing to the greenhouse effect. When the subject is environmental concerns, methane is known to be many times more aggressive than carbon. Since the production of this gas is inherent to the pig farming industry, its effects can be mitigated by using it as fuel in an engine to drive an electricity generator, while adding value to the production chain.

Highlights

Electric energy performs a fundamental role in the lives of human beings, which sits alongside other fundamental modern day essentials such as transport, telecommunications, treated water and sewage, which together create an infrastructure that is necessary for incorporating the human being into the current model of development
In light of the applicability of the squirrel cage induction generator - asynchronous technology, there arises the need for a design, economic and technical viability study of the squirrel cage induction generator in distributed generation that uses methane gas that comes from the pig industry as primary or mechanical power
The Brazilian pig herd has expanded in a significant manner over recent years, with an average annual growth of approximately 8% according to data from the Brazilian Institute of Geography and Statistics/Instituto Brasileiro de Geografia e Estatística (IBGE), reaching in 2011 a number of approximately 39 million head [38]

Summary

INTRODUCTION

Electric energy performs a fundamental role in the lives of human beings, which sits alongside other fundamental modern day essentials such as transport, telecommunications, treated water and sewage, which together create an infrastructure that is necessary for incorporating the human being into the current model of development. In a situation of disconnection from the grid, the asynchronous generator demagnetizes, stops generating terminal voltage, in this way it becomes an induction generator of the squirrel cage type, which is an ideal candidate for distributed generation due to its operational characteristics These environmental and financial advantages are linked to the burning of methane gas, as it can generate clean energy, since it is produced naturally in the productive chain of pig farming. In light of the applicability of the squirrel cage induction generator - asynchronous technology, there arises the need for a design, economic and technical viability study of the squirrel cage induction generator in distributed generation that uses methane gas that comes from the pig industry as primary or mechanical power. Given the bibliographic survey it is noted that there is no study relating the technical, economic and implementation project of the induction generator design from the renewable energy from the burning of methane gas from pig farms
