Loss due to Power Transmission and Distribution
Facilities
• As per Ethiopia standard power loss is considered as 10%
• Power transmission and distribution loss
80kW × 10% = 8kW

Reserve Capacity for System Stability and Failure
• As per Ethiopia standard Reserved system capacity is
considered as 10%
• Reserve Capacity for System Stability and Failure
80kW × 10% = 8kW

Total Demand for generation
• Maximum Load at Demand End = 80KW
• Power transmission and distribution loss = 8KW
• Reserve Capacity for System Stability and Failure = 8kW
• Total = 96KW
• So our Micro Hydro-Electric power plant will generate
100KW which satisfies the total demand.

Components Of The Plant And Their
Role In Its Working
Functioning of a hydroelectric power plant
 Hydroelectricity is produced in a hydroelectric power
plant. In this plant, the water is released from a high
location. The potential energy present in the water is
converted into kinetic energy, which is then used to
rotate the blades of a turbine. The turbine is hooked to
the generator which produces electricity.

Components Of The Plant And Their Role
In Its Working
 Here are the basic components of a conventional
hydropower plant:

The main components of hydroelectric
power plant
• A) The reservoir: Water from a natural water body like a
river is stored in the reservoir. This reservoir is built at a
level higher than the turbine.
• B) Forebay
• Purpose: Acts as a buffer and additional sedimentation
area; regulates water flow into the penstock.
• Design: A small tank or reservoir equipped with a spillway
to manage overflow and a trash rack to stop debris.

power plant
• c) The penstock: Purpose: Transports water from the
intake or forebay down to the turbine under pressure.
• Design: A long pipeline made from materials capable of
withstanding high pressure, such as steel or reinforced
plastic. The diameter and strength are determined based
on the flow rate and the head
• .d) The turbine: The kinetic energy of the running water
turns the blades of the turbine. The turbine can be either
a Pelton Wheel Model or a Centrifugal type. The turbine
has a shaft connected to the generator.

• The most common type of turbine for hydropower plants
is the Francis Turbine, which looks like a big disc with
curved blades. A turbine can weigh as much as 172 tons
and turn at a rate of 90 revolutions per minute (rpm),
according to the Foundation for Water & Energy
Education (FWEE).
• e) The generator: A shaft runs from the turbine to the
generator. When the blades of the turbine rotate, the
shaft turns a motor which produces electric current in the
generator.

 Giant magnets rotate past copper coils, producing
alternating current (AC) by moving electrons. (You'll
learn more about how the generator works later.)
 f) Power lines: The power produced in the generator
is sent to various power distribution stations through
the power lines.

 The Generator
The heart of the hydroelectric power plant is the generator.
Most hydropower plants have several of these generators.
