DEVELOPMENT OF A HIGH SPEED ELECTRICGENERATOR AS A RENEWABLE ENERGY

TECHNOLOGY (RET) MODEL FORCOMMERCIAL AND RURAL COMMUNITY

BACKGROUND

Zimbabwe had a generating capacity of

about 2100MW of electricity but as of 29March 2012 its electricity production stood at

1120MW.

Zimbabwe however has a power

consumption of about 2500MW,therefore

production does not meet demand.


3/37

At present the below mentioned generator

related problems have affected production

in the countrys power stations.

Generator rotor earth fault

Generator winding problems

Rotor vibration problems

Shorted rotor turnsBreakdown in ground wall insulation

Thermal cycling and coil abrasion in the

slot.


4/37

The desire to ease the countrys electricity

problems involves utilizing some of the

nation's idle lying biomass points.

For the points to be utilized electric power

plants need to be designed which leads to

the DEVELOPMENT OF HIGH SPEED

ELECTRIC GENERATORS for utilization

in small and large scale power plants.


5/37

Most of the generators being used in our

power plants in Zimbabwe have long

outlived their life spans and new designs

are needed

Improvements in electrical machine design

in the 21st century have made it possible to

redesign electrical machines to solveexisting design problems

Power plant generators are not

manufactured in Zimbabwe.


6/37

The new design seeks to come out with an

electrical power plant generator that

should

Adapt to processes with high power plant

efficiency

Meet increasingly stringent requirements

for operating behaviourHave lower size and weight so as to be

cost effective as well as durable and

minimises the generator faults.


7/37

Learn relevant design skills including

production of design drawings using

relevant computer software.

Establish production methods for model

with the help of a local company,

organization and or institution using locally

available resources.Perform calculations, develop detailed

drawings and design sheet for RET model

And evaluate performance


8/37

Although the country Zimbabwe has abundantrenewable resources they however have not

been fully utilized.

Small hydro projects producing power in theoutput ranges of 1-10KW are popular in Africa

but however not in Zimbabwe.

Few biomass power plants exist especially 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.
