Question

How is electricity produced in hydroelectric power stations ?

Answer 1

BRIEF ANSWER - Hydropower plants capture the energy of falling water to generate electricity. A turbine converts the kinetic energy of falling water into mechanical energy. Then a generator converts the mechanical energy from the turbine into electrical energy.

Answer 2

Hi there ...

As we know , it is a flowing water that creates the energy required to generate electricity,

Wonder how it works ??

Well , there is a huge amount of energy created from the falling of water.
This energy is harnessed by forcing it through a pipe , which is called a pen-stock.

At the end of the pipe , there is a turbine propeller.
So , when water flows through the pipe , it reaches the propeller , and turns the blades of the turbine.

This spins an electric generator.
Hence , as long as water is flowing , the generator will be spun , and there will be electricity.

There are mainly three ways in which hydro electric plants are designed.

The most common type follows a storage system.
To put it clearly , there is a dam used in this system.
It slows the flow of river and stores the water in a reservoir above it .
When needed , a portion of water is released into the river flowing below the dam.

The pressure , thus created from the fall of water , spins turbine generators lying below.
From this is created hydro electricity.

Yet , another is the run - of - the - river - system.

Here , turbines are spun by natural flow of the water

The third type follows the pumped storage system.
This is similar to the first type of storage system.

But , the difference is that , it uses pumps to pump the used water back into the reservoir .
