DESIGN AND FABRICATION OF
MINI HYDROELECTRIC POWER
• As energy becomes the current catchphrase in business,
industry, and society, energy alternatives are becoming
• Hydroelectricity exists as one option to meet the growing
demand for energy and is discussed in this paper.
• The hydro-powered generator uses fast-flowing warer that
are usually located on storage tank
• A small-scale system is comprised of an intake, a
pipeline, a turbine and a generator. The water is collected
via an intake area then transferred from the stream
through a long pipe (also known as a penstock).
• Most machines that make electricity need some form of
mechanical energy to get things started. Mechanical energy
spins the generator to make the electricity.
• In the case of hydro electricity, the mechanical energy
comes from large volumes of falling water. The simplest
way to produce the volumes of falling water needed to make
• In this activity, we will use fiber blade to build a model
of a simple micro-hydro system. It generates surprising
amounts of electricity, provided you have a supply of
pressurized water, such as from a lab sink.
TYPES OF TURBINES
1. According to the action of the water flowing:
a. Impulse turbine e.g. Pelton wheel
b. Reaction turbine eg .Francis and Kaplan turbine.
2.According to the main direaction of flow of water
a.Tangentional flow e.g. Pelton wheel
b.Radial flow e.g . Old francis turbine.
c.Axial flow turbine e.g Kaplan turbine.
d.Mixed flow turbine e.g . Modern francis turbine.
The water is collected into the tank ,so it serves as a water reservoir. The
potential energy for further work is generated by the water level
Difference between the tank and the turbines because the water level in
the is very high. Tank also control the water flow through penstocks.
The hydroelectric power generator working principle is nothing but the
water force applied on the blade then the blades are rotated in rotary
The shaft is rotated by applying of water force then the shaft is rotated
into clockwise rotation.
After that power will produced.
• Almost every mechanical movement that we see around us is
accomplished by an electric motor. Motors take electrical
energy and produce mechanical energy.
• A direct current (DC) motor is a fairly simple electric motor
that uses electricity and a magnetic field to produce torque,
which causes it to turn
• At its most simple, it requires two magnets of opposite
polarity and an electric coil, which acts as an
• The repellent and attractive electromagnetic forces of the
magnets provide the torque that causes the motor to turn.
Multiple definitions of total fiber are recognized;
however, the most recently accepted definition is that
Total Fiber is the sum of Dietary Fiber and Functional
Dietary Fiber, also called roughage , bulk, and viscous
fiber, include non-digestible carbohydrates and lignin
most commonly found in plants.
Eating foods with fiber is important for proper bowel
function and can reduce symptoms of chronic
constipation, diverticulosis, and hemorrhoids.
Populations with low intakes of dietary fiber may
have more heart disease, obesity, and some cancers.
Fiber is associated with are duced incidence of these
chronic health problems, although the precise
protective factor is yet unknown.

1. HYDROELECTRIC POWER GENERATION AND
Mohinder Kumar Slariya
In the era of rapid industrialisation consciously or
unconsciously he unscientifically utilize the natural
resources and resulting into the major problems of 21st
century including environmental pollution and global
warming on the one hand and creating more problems to the
human beings by ignoring human dimensions.
2.ELECTRICAL CHARACTERISTICS OF MICRO
HYDRO POWER :Arun Varughese, Prawin Angel
The most important problem faced by a
country like India is that of rural electrification.
This paper proposes a permanent magnet
synchronous generator (PMSG) based micro
power plant, which is used for a standalone micro
hydro power generation.
• No Fuel Required.
• No Air pollution is required.
• Long Life in omparison with the thermal &
nuclear power plant.
• No ash & fuel gas problem & does not pollute
with the atmosphere

After investigating the various impacts of a hydroelectric
plant, we were able to determine the feasibility of
implementing a hydroelectric plant.
Since most environmental concerns stem from
construction of the tank, this location would not be
greatly affected by the installation of a hydropower
Also, taking into the consideration that this is a highly
scenic site of recreational value, we will only partially
disrupt the volume of water over the tank, using about 19
percent of the flow.
Most environmental concerns are mitigated by the fact
that the area is already partially developed for a project
