How hydroelectricity is generated?
Before knowing about how hydroelectricity is produced we have to know about what do you mean by hydroelectricity. Hydroelectricity is the electrical energy which is produced by converting the mechanical energy of the water to electrical energy. There are total three sections in hydroelectricity power plant.
1) Dam:
It is also known as the reservoir of water. In dam we collect water for the future propose cause in some season due to lack of water we have to close the production but as dam has the reservoir of the water we can use it in that season when we lack water and produce electricity.
Also there are some hydro power which doesn’t has dam and use running water for producing electricity which is also known as RUN OF THE RIVER hydro power plant.
2. Tunnel :
Tunnel is the part of the power plant which is responsible for making water flow from dam towards the turbine. There are also various types of tunnel used as types of hydro power plant.
3) Generation house:
In this unit there the actual production of the electricity takes place. Here we can find the turbine which will rotate as the flowing water hits it blade. This turbine rotating shaft is connected to the shaft of the generator which leads to cut the magnetic field.
When the gate of the dam is open then the water starts to flow through tunnel and through tunnel it reaches to surge tank which is near to the generation unit. This surge tank is used to mitigate pressure variation due to rapid changes in velocity of the water. As water flows through surge chamber it hits blade of the turbine and rotate the shaft of the turbine. And as the shaft of the turbine is connected to the rotor of the generator there the rotor also starts rotating and then the generator produce electricity.
