1:INTRODUCTION

1.1:BACKGROUNDAccording to the IEA-Energy outlook 2004 some

1.6 billion people about one quarter of the world'spopulation,have no access to electricity.80% of

these people live in rural areas of the developing

world.

Without adequate supplies of affordable energy,it

is virtually impossible to carry out productive

economic activity or improve health and

education.Zimbabwe is currently experiencing serious power

shortages and having excessive load shedding.

A wide range of factors are of course responsible

for the power shortages.

BACKGROUND Cont'dIn as much as the entire nation is blaming the

national utility,Zimbabwe Electricity Supply

Authority,(ZESA),for the powershortages,emphasis needs to be shifted on howwe can find ways that more electricity can beproduced as well as utilizing that which is alreadybeing produced.

Zimbabwe has an installed capacity to produceabout 2100MW of electricity.

Electricity is generated locally at

Hwange(920MW),Kariba(750MW),Harare(135MW),Bulawayo(120MW) and Munyati (120MW )

As the supply falls far short of thedemand,electricity supply is sometimes

augmented by imports.

BACKGROUND Cont'dAs the power supply falls far short of the

demand

However ,electrical machine design in the21st century has been made even more

possible because of the advent of fast,

efficient computer software and the ability tocarry out much iteration quickly and cheaply.

The impetus is now on the design Engineer

to arbitrarily design and perform calculationsrather than actually performing them. These

latest developments in design have enabled

the solving of many design problems.

BACKGROUND Cont'dThe acute shortage of electricity in

Zimbabwe has heightened the need to

consider alternative generation modes.Some companies like Triangle Ltd

produce their own power while othershave resorted to using diesel and petrolgenerators to supplement the nationalgrid.

However this has proved to be very

costly for companies leading todiscussions on less costly and morerealistic approaches to electricitygeneration.

1.2:PROBLEM STATEMENTThe desire to come out with alternative

generation modes involves utilizing some of

the nation's idle lying biomass points in theSouth eastern lowveld and in the Eastern

highlands.

For the points to be utilized correspondinglysmall scale electric power plants need to be

designed which leads to the

DEVELOPMENT OF HIGH SPEEDELECTRIC GENERATORS AS A

RENEWABLE ENERGY TECHNOLOGY

MODEL FOR COMMERCIAL AND RURAL

APPLICATIONS

1.3:JUSTIFICATION

Previously electrical machine design and attempts to

disseminate RETS have encountered unforeseen

barriers,The 21st century has seen the advent of fastand efficient computer software and design

techniques which help in the realizations of these

ventures.

Barrier removal work like this project which aims at

design and construction are very important so that

future projects will avoid pitfalls experienced by

earlier initiatives. If successful this project promises to be a model for

the integration of large scale and

community/household scale sustainable biomass

energy management.

1 4 OBJECTIVES

1.4:OBJECTIVES

Learn relevant design skills including

production of design drawings using relevantcomputer software.

Establish production methods for the RET

model with the help of a localcompany,organization and or institution using

locally available resources.

Perform calculations,develop detaileddrawings and design sheet for RET model.

And evaluate performance

2:LITERATURE REVIEW

2.1IntroductionRETs have over the years become an

integral part of the energy supply chainin most developed countries. Recent

projections show that 13.5% of the

world's primary energy supply comesfrom renewable resources and that this

figure has an aggregated growth rate of

16%.Although the continent Zimbabwe has

abundant renewable resources,these

have not been fully utilized.


10/1810

Literature review cont'dSmall hydro projects producing power in

the output ranges of 1-10KW are gaining

popularity in Africa particularly as isolatedpower supply schemes for village

electrification.

However few biomass power plants existespecially in Zimbabwe where we have

Triangle Ltd as one of the biomass power

plant points.These companies have not extended their

electricity supply to neighboring

communities.


11/1811

2.2:DESIGN PROCESS

The design process is a series of steps that are

used as guidance in problem solvingThe design process is cyclical and is

fundamentally a process that is highly

computational and iterative.

The initiation of design of the high speed electricgenerator requires specification of performance

The main areas of design are the magnetic

circuit,the electric circuit and the heating andcooling circuit. A simple generalized design

process of electric generators has been

developed and outlined below

3:METHODOLOGY

In carrying out this project variousmethods of gathering reliable datasuch as interviews, deskresearches and internet researcheswill be used.

Oral interviews will be carried outwith companies whose input inresources and information areessential to the success of the

project in Zimbabwe.The internet and literature from

the university library will also be

used. A design of the lab model

4:EQUIPMENT AND MATERIALSThe initial stage in design procedure is the

selection of suitable basic materials to

use.Conducting materialCopper is the most suitable material to use

for electrical machines. Availability of

copper is fast becoming compromised asa result of dwindling deposits of copper aswell as its price fluctuations. Thereforecopper is fast being replaced by

aluminum.Magnetic materialSilicon steel is the most important for

construction of electrical machines.Insulating material

Equipment and materials contd

For the synchronous generators the

desirable characteristics of the magneticcircuits are shown in the table below.

A variety of other construction materialsand equipment like windings, ball bearings,drilling machines, centre lathes and othermachining equipment are required. Most ofthe stator and rotor construction materials

would be supplied by Relmo.
