The Hydropower Generating Station

A hydropower generating station produces electricity through the power of water. Let us see what a station contains and how it operates!

Generator

1 Rotor
Mobile section of the generator covered with electromagnets fed by an exciter. The rotor turns inside the stator, thanks to the rotation of the turbine shaft set in motion by the force of the turbine.

2 Stator
Stationary section of the generator, made up of copper windings.

3 Exciter
Piece of equipment located at the top of the generator. The exciter is made up of a rotor and a stator. Its function consists of producing a direct current to feed the rotor's electromagnets.

4 Copper Windings
Windings facing the rotor's electromagnets. Cooper is a good electrical conductor.

1-Dam
Structure generally made of concrete built on a riverbed to retain and accumulate water to be used to produce electricity.

2-Reservoir
Area where water retained by the dam is stored to produce electricity.

3-Water Intake
This is a structure that directs water from the reservoir or river to the penstocks. Debris traps prevent the entry of debris.

4-Penstock
This is a huge metal pipe, concrete channel or channel carved in rock that directs water from the intake to the turbine scrollcase.

5-Turbine
Piece of equipment made of steel and equipped with a metal scrollcase. The power of water causes the scrollcase to turn. The turbine transforms the energy of water into mechanical energy, causing a shaft to rotate and power the generator.

6-Generator
This piece of equipment is the only component to produce electricity at the generating station. The generator is made up of a rotor and a stator. Rotating the rotor causes electrons in the copper windings in the stator to vibrate, creating an electric current.

7-Tailrace
Structure that redirects water flowing through the turbine to the natural course of the river.

Turbine

1-Wicket Gate
Helical-shaped conduit around the scrollcase that ensures consistent water distribution. The wicket gate directs water from the penstock to the turbine's scrollcase.

2-Scrollcase
Mobile component of the turbine mounted horizontally on the turbine shaft. The scrollcase is powered by the flow of water. It causes the shaft to spin and rotate the generator.

3-Turbine Shaft
This piece of equipment connects the turbine to the generator. The shaft transmits the mechanical energy of the turbine to the generator's rotor. Set in motion by the turbine scrollcase, the shaft causes the rotor to spin.

4-Draft Tube
Located under the turbine, it evacuates water while diminishing its flow towards the tailrace.
