Let’s make an excursion to the Novosibirsk HPP. This time we won’t use any technical terms and will try to explain the principle of its work as accessibly as possible.
A control panel. The management and monitoring of the condition of the whole plant is carried out in this room.
“Earthed”, “Don’t turn on! People are working”
Everything is computerized.
This is not a print screen.
The process of the conversion of water energy into electricity begins here. At first, water intakes suck water into a turbine.
The water layer is about 4 meters deep, so fish which swims even deeper is not hurt. Even if it gets into the turbine, it will survive.
The process of closing and opening of the valves of the water intakes takes place in this room.
Now let’s go down to the turbine. It’s right under our feet. On the left – the axis of the rotor.
When water enters the turbine and rotates the blades (and the rotor respectively), the energy of water is converted into the energy of the rotor. The axis goes up.
Now let’s climb higher, closer to generators.
A turbine hall, the generators are on the right.
Let’s enter one of them.
The sluice of the generator.
The same axis.
The winding of the generator (the movable one) spins right over our heads. And the stator (the stationary part of the winding) revolves around it.
Due to the rotation of both of them, there appears an electromagnetic field which produces an electrical current. So the energy of the rotor turns into electric energy. The following process takes place outdoors but let’s first climb to an engine room.
The engine room. Here you can see the crowns of hydroelectric generators.
The burning ball indicates that the hydroelectric generator is working now.
“Don’t get in. It’ll kill you”
No plant can possibly be without his picture.
If something gets broken, it’s transported to the repair room with the help of such an overhead crane.
The repair room.
Now let’s go outside.
So, electricity has been produced but has a very big current. What to do? How can it be delivered to people’s homes?
