Electricity is generated in power plants; however, although this assertion does not seem to be particularly revealing, the production process is a little more complicated.
The hard coal or lignite supplied to the power plant is ground into very small pieces and burned in massive furnaces that produce high temperatures. The thermal energy produced heats the water, which condenses into high-pressure steam with a temperature of 600 degrees. Simply put, this pair drives a turbine that is linked to a power generator that rotates and transforms mechanical energy into electricity.
Hydropower plants operate on a similar concept, with the exception that the mechanical energy that drives the turbine is provided by the force of water flow. The water collected in the tank is lowered onto the turbine, which is powered by the force of its fall and thus generates electricity. Wind farms – where windmills are powered by the wind – and solar power plants – where radiation drives special panels – all use renewable energy.
Conversion And Transportation Of Electricity
The electricity must be transported after it is produced in the power plant. For this, special overhead cables with a wide cross-section are used, and the data is transmitted along with them.
Transformers are special devices that adjust the current’s parameters. Then there are transmission lines, which are mostly tall and wide “towers” between which cables are hung outside of cities. They are responsible for transporting our energy. The largest ones operate at the highest voltages, or to put it another way, they carry the “strongest current.”
They pass through transformer and distribution stations along the way, where they split and proceed to lower-voltage lines. These are known as distribution lines (usually 110kV), and they carry electricity to the Main Supply Point. A substation is a facility that converts energy into medium voltages. Each of these points is responsible for supplying energy to the local distribution network and serves a particular region.
Cable Network
The remainder of the energy delivery system varies depending on where it wants to go. It travels from the GPZ to the underground cable network in cities, where it is already divided by Internal Power Lines, and then to the houses (WLZ). Smaller lines, which are very low poles with relatively thin cables that carry energy to the receiver by air, are used in rural areas. The job of electricians comes next.
Small wires that bring electricity to individual sockets and light fittings are concealed under the wall surface within the building. The energy eventually reaches the consumer after travelling such a long distance.
Renewable Energy Sources’ Advantages, i.e. Ecological Power Sources
Photovoltaics generate electricity in a variety of ways. Photovoltaic panels produce direct current by absorbing photons from the sun’s rays. This is sent to an inverter, which converts direct current into usable alternating current at home. Electricity is used on a continuous basis, with surpluses being fed into the power grid. Photovoltaic panels mount on building roofs, fences, and other special structures.
