What is a power plant?

Power Plant Definition: A power plant (also known as a power station or power generating station) is an industrial facility for generating and distributing electric power on a large scale. Types of Power Plants: Power plants are classified based on the fuel used: thermal, nuclear, and hydroelectric are the main types.

What is a power plant or powerhouse?

Q : What is a 'power plant' or 'powerhouse' ?A : A power plant or powerhouse, and sometimes generating station or generating plant, is an industrial facility for the generation of electric power. Most power plants contain one or more generators, a rotating machine that converts mechanical power into electrical power.

How does a generator work in a power station?

At the center of nearly all power stations is a generator, a rotating machine that converts mechanical energy into electrical energy by creating relative motion between a magnetic field and a conductor. The energy source harnessed to turn the generator varies widely.

Which type of generating station should be chosen?

So, as we know the type of load and approximate amount of load at the station, different type of generating station is chosen. For example; Thermal plant, Hydel plant, Nuclear plant, Solar plant, Wind plant and Tidal plant are chosen to handle the base load on the system whereas Gas plants, Diesel plants are used to handle peak load demand.

Which energy source is used to turn a generator?

The energy source harnessed to turn the generator varies widely. Most power stations in the world burn fossil fuels such as coal, oil, and natural gas to generate electricity. Fossil-fuel power stations may also use a steam turbine generator or in the case of natural gas-fired plants may use a combustion turbine.
