A diesel power station or standby station is that the plant once we use ICE as the main mover or mix an ICE with an electrical generator to provide voltage by exploitation fuel or liquid fuels like gas.

For generating electric power, it’s essential to rotate the rotor of Associate in Nursing generator by suggests that of the main mover. The first cause may be driven by totally different ways. exploitation ICE as first cause is one in all the popular ways of generating power. once the first cause of the alternators is ICE, the ability station is named diesel station.

Diesel Power Plant

The mechanical power needed for driving generator comes from the combustion of diesel. because of the diesel prices are high, this kind of station isn’t appropriate for manufacturing power in giant scale in our country.

Components of diesel power plant:


Engine Starting System:

it’s employed in recent conditions as a starter because it uses the air to push the engine and begin associate initial rotation until the engine run with its own power.

Fuel Supply System:

it consists of a vessel wherever we have a tendency to store the oil equipped to the plant, all day fuel tank wherever the oil pumped up for usage, the filter that accustomed take away suspended impurities of the oil, and mechanical system (transfer) pump that accustomed inject the clean oil into the engine.

Cooling system:

It’s important within the diesel station to possess a cooling system to keep up the temperature of the engine at an enjoyable level, and this cooling system needs a water supply, a pump that circulates water through a cylinder, and cooling towers that accustomed cool the new water.

Diesel Engine

Lubricating system:

it’s accustomed minimize we have a tendency toar|the wear associated tear|the damage} of the rubbing surface of the engine as we store oil in an exceedingly main grease tank then draw this oil from a pump to withstand the filter to get rid of impurities.

Exhaust system:

The exhaust gas is far from the engine, to the atmosphere by suggests that of associate degree exhaust. A silencer is often utilized in this method to scale back the background level of the engine.

Governing system:

it’s accustomed management the speed of the engine by dynamical the fuel gives in line with engine load.

Air intake system:

This system provides necessary air to the engine for fuel combustion. It consists of a pipe for a supply of contemporary air to the engine. Filters area unit provided to get rid of dirt particles from the air as a result of these particles will act as associate degree abrasive within the engine cylinder.


it’s wont to take away solid impurities from the oil transferred from the most tank to tiny dry tank through this filter.

Applications of diesel power plant:

  •  Diesel power plants are within the vary of two to fifty MW capability. they’re used as the central station for little or medium power provides.
  • They can be used as standby plants to hydro-electric power plants and steam power plants for emergency services.
  • They can be used as peak load plants in mixtures with thermal or hydro-plants.
  • They square measure quite appropriate for mobile power generation and are widely utilized in transportation systems like cars, railways, airplanes, and ships.
  • Nowadays power cut has become an everyday feature for industries. the sole resolution to serve this issue is to put in diesel generating sets.

Diesel power plant working principle:

Diesel Plant Working

The working rule of the diesel power plant is incredibly simple; as we have a tendency to compress the air in an exceeding cylinder to boost the temperature, then we have a tendency to burn the diesel within the engine and therefore the combustion produces the operating fluid at warmth and high to convert the warmth energy into energy. And because the diesel acts as a chief mover it rotates the rotor of the electrical generator and converts this energy into voltage.

This working rule may be an operating cycle done by the processes: intake, compression, expansion, and exhaust.

Advantages of Diesel Power Station:


  • This is easy in style purpose of reading.
  • Required terribly little house.
  • It may be designed for moveable use.
  • It has the fast beginning facility, the tiny diesel generator set is started among a few seconds.
  • It may be stopped as once needed stopping little size diesel power plant, even easier than it’s beginning
  • As these machines will simply be started and stopped as once needed, there might not be any standby loss within the system.
  • Cooling is straightforward and needed a smaller amount of water during this sort of power plant.
  • The initial value is a smaller amount than alternative styles of the power plant.
  • Thermal potency of diesel is sort of above of coal.

Disadvantages of Diesel Power Station:

  •  As we’ve already mentioned, the value of diesel is extremely high compared to coal. this can be the most reason that a diesel powerhouse isn’t obtaining quality over different means that of generating power.
  • The plant usually wont to turn out little power demand.
  • Cost of lubricants is high.
  • Maintenance is kind of complicated and prices high.
  • The plant doesn’t work satisfactorily beneath overload conditions for an extended amount.
