Hydroelectricity and hydroelectric power plants working method

Hydroelectricity power plants


Hydroelectric power plants produce hydroelectricity. These plants convert the power of flowing water into electricity.



A hydroelectric power or often also called Hydroelectric Power Plant is a source of electricity generation that uses a turbine to drive energy that comes from water.


The primary reason for making hydroelectric power plants is that we could irrigate our barren land via dams.


A dam is an alternative source of generating electricity and provides electricity to homes for residents far from power plants.


You must read about the history of electricity.


How does Hydroelectric Power Plants Work



The working method of a Hydroelectricity Power Plant is how it converts water energy into electricity. The utilization of water is very important to drive turbines.


The water in the dam goes down into the hole and rotates a large turbine/fan, the deeper the hole, the faster the water flow, which will rotate the turbine at a very fast speed. The rotation of the turbine will produce mechanical energy and an attached generator will convert it into electrical energy.


Hydroelectric Components and How they Work


1. Reservoir / Dam


Reservoirs/dams function to store large amounts of water because turbines require an adequate and stable water supply. In addition, reservoirs/dams also function to control flooding and its design to irrigate the barren land.


2. Penstock pipe


This tool serves to channel and provide direction to water to the turbine chimney. We install the one end of the pipe in a mini-sink 10 cm above the ground floor. While at the other end, we direct it to the turbine chimney.


3. Turbine


The force of water falling on the propeller causes the turbine to spin. Water turbines are mostly like windmills. The turbine converts the force of falling water (potential energy) into kinetic energy.


4. Generator


We connect this tool to the turbine through the gears so that when the turbine blades rotate, the generator will also rotate. The generator uses the rotation of the turbine to rotate the magnetic coil inside the generator so that there is a movement of electrons that generates an AC current.


5. Transmission Lines


This transmission line serves to carry electricity from the hydropower plant to homes or industries. We reduce the voltage by a step-down transformer.
