Although we think that the internet is one of the most indispensable things we need to stay connected with society, the truth is the power grid is more important than that. Without power, you cannot run any appliances within your home, be it internet, TV, washing machines and so on.
Indeed, your grid plays a major role.
If you are wondering what this term is all about and how it works, then keep reading this post.
What is the Power Grid?
Also known as the electrical grid, it is basically a network that interconnects the distribution, transmission, and generation unit. This grid is responsible for supplying electrical power, ranging from a generating unit to the distribution unit. Recall that 220kv or higher power is transmitted from the generating station to the load center. The network created by these high-voltage lines is known as the ‘Super Grid,’ which feeds the sub-transmission network at 132 kV or less.
Basically, there are two types of grids. These grids are known as the Regional and National grid.
The regional grid interconnects various transmission systems of a specific area through the transmission line. Whereas the National grid is generated by interconnecting the grid of different regions.
How Does the Power Grid Work?
The nature of the grid is pretty simple. You can ask any electrician and he could tell you how it works. There are a few aspects involved in the procedure, these are present below.
The power plant
Electric power usually begins at the power plant and it consists of a spinning electric generator. The generator can be spun either with a large engine, gas turbine, or wheel in a hydroelectric dam. But in most cases, the steam turbine spins the generator. The steam can be made by burning natural gas, oil, or coal.
The energy derived from the power plant is then sent to transformers, which ultimately converts electricity into a lower voltage.
After the generation of electricity, it goes to your home or office. Electricity is transmitted from a power source either through underground cables or through overhead power lines. These transmission lines are owned by electrical companies but you can also get them at independent Regional Transmission Organization and System Operators.
Transmission lines are in line with distribution centers that transmit power to the homes and businesses. The network of transmission lines, distribution centers, power sources, and transformers make up the entirety of the electrical grid.
Natural gas, nuclear and coal have always been the lifeline of the electrical grid. However, any electrician could tell that tracking electricity or progressing into significant clean energy at the moment is nearly impossible as there are still many countries that still rely on fossil fuel power resources into the electricity grid.
