Hydro Power Plant

the power plant is defined as the place where power is generated from a given source, so here the source is hydro that’s why we called it hydro power plant.

In hydro power plant we use gravitational force of fluid water to run the turbine which is coupled with electric generator to produce electricity.

The big advantage of hydro power is the water which the main stuff to produce electricity in hydro power plant is free, it not contain any type of pollution and after generated electricity the price of electricity is average not too much high.

Pumped Storage Power Plant

Pumped Storage Power Plants are a special type of power- plants, which work as conventional hydropower stations for part of the time.

In a hydroelectric power station water is stored behind a dam in a reservoir. This water has gravitational potential energy.

the water runs down through pipes to turn the turbine the turbine is connected to a generator to produce electricity ( They are mainly used to meet the peak demand.

Working of Pumped Store Plant

 The working of the power station can be distinguished as the pumping phase:- when the pump and motors are in operation generating phase:- when the turbines and generators are electrical

power

At pumped storage hydroelectric stations water is pumped back into the reservoir when there are periods of low power demand. This is often when there is excess energy being produced by other power stations.

This stores energy and during higher demand periods the water can be allowed to flow back down to produce electricity just like a normal power station. Such a system saves energy and also can be turned on quickly at times of peak demand.

Upper ReservoirWhen power from the plant is needed, water stored in an upper reservoir is released into an underground tunnel.

Intake TunnelThe water rushes down the intake tunnel.

TurbinesThe force of the water drives huge turbines, which are underground at the base of a dam. The spinning turbines are connected to large generators, which produce the electricity.

Discharge TunnelThe water then flows through a discharge tunnel into a lower reservoir.

RechargingWhen demand for electricity is low, the turbines spin backward and pump the water back up into the upper reservoir to make it available to generate electricity when it's needed.

Working

Advantages

No Pollution or waste. Its Renewable can pick up load rapidly in a matter of few minutes. It is very reliable because we can release the water to make energy

when we need it.

Disadvantage

little effect on landscape Once it's used, it can't be used again until the water is pumped back up. The main disadvantage is specialist nature of the site required, needing

both geographical height and water availability. Expensive to built.
