A country can move forward if it has good source of Power Generation with Transmission and Distribution system. By amount of power generation, we can determine a countries overall development. We will find lots of country those who ensure a well established power system and they are leading the world. It also can be depend how many source a country have to generate electric power.
Those countries have fossil fuel like Cola, Gas and Oil they can easily convert this energy to electricity. But now a day the price of fossil fuel moving upward and generating low cost electricity getting impossible.
Establishing a Nuclear Power Plant is more expensive and for a small country cannot afford it. But if you want to use a renewable energy source for generating electricity then it also quite expensive and has less place where we can built a plant.
Basic Operation of a Power Plant:
First of all I want to define a Power Plant. Power Plant is a center or an institute where we can generate electricity by using Generator and for this reason we need fuel or some source of energy that we can convert it by existing generator to electricity.
Normally generation voltage is about 11KV (Most of Time) and it is directly connected with national grid. That’s means lots of power station can connect with power grid and together can be a well established power network. A power station can have several Generators with different capacity.
But all generators can connect with each other by synchronizing system. After generating electricity we need a transmission and distribution network that we can receive power to our home and office. Transmission and Distribution system is inside parts of national Grid Network. But a privet origination can build its very own power network.
If we want to transfer our generated electricity to a long distance then we need to step up our voltage for reduce voltage loss. Because a long distance transmission line has voltage loss, for cable resistance. Voltage can be step up by a Step Up Power Transformer.
Now at the user end, again we need to reduce voltage level. Because our daily electrical equipments will not work with high voltage. Now we need to step down the voltage by a Step Down Power Transformer to get the required voltage level like 110V to 220V. If you want you can read this article, How is Electricity Produced and Delivered to Our Homes?
Generator, Transformer, Switch Gear, Control Gear is most common electrical equipments in a power plant. Generator has a prime mover and for generating electricity we need to rotate the prime mover. There is several ways like Natural Energy, Fuel Energy, Nuclear Energy, Solar Energy we can rotate prime mover.
But for choosing the transmission voltage must have the maximum performances, improved regulation and better plant economic. Generally by using a Step Up Power Transformer we can step up our generated voltage to 132KV voltage and sent it to the transmission system or network.
Then a receiving substation step down this 132KV voltage to 33KV voltage and then this voltage is transferred to distribution substation. But it can be different at your region. Then 33KV voltage line sent to is step down to 11KV voltage and again 11KV voltage to 0.415KV or 415V (Line to Line, Three Phase) and 220V (Line to Neutral, Single Phase).
Use and Importance of Power Plant:
Generating low cost electricity is the key of development for a growing country. Electricity is essential not only for Residential and Industries but also for agriculture. You may ask why electricity is important for agriculture. Because, water is common substance for agriculture.
If there is no nearby river then you have to go deep in to the earth for water. Without electricity is nearly impossible to get water from deep earth. We are already habituated in our daily life with electricity which coming from nearby power station. Even when you are reading this article by using your computer or cell phone then you are using electricity to keep alive your device.
So there is no way that we can live without electricity. For this reason all power plants across your country keeping good impact in our daily life by providing smooth supply of low cost electricity.
Now I am going to give you some reason or advantage why Electrical Power is so useful than any others source of energy.
- Electricity is convertible. According with demand we can change its voltage level.
- It’s easy to control.
- It’s available.
- Low cost according to fuel.
- It’s clean and not harmful for nature.
- We can transfer electricity at any distance by over head transmission line.
But after all this advantage lots of countries in this world are suffering for electricity and main reason behind is the source of energy to generate electricity. But our demand is getting higher day by day. For this reason power plant is much important to our national development.
Now if you have any question according with power plant then ask in comment and don’t forget to share this article with your friends. Thanks!
