The prime mover can be driven by different methods. Using diesel engine as prime mover is one of the popular methods of generating power.
When prime mover of the alternators is diesel engine, the power station is called diesel power station. The mechanical power required for driving alternator comes from combustion of diesel.
As the diesel costs high, this type of power station is not suitable for producing power in large scale in our country. But for small scale production of electric powerand where, there is no other easily available alternatives of producing electric power, diesel power station are used.
Steam power stations and hydro power plants are mainly used to produce maximum portion of the electrical load demands. But for Diesel power plant thesis power station, sufficient supply of coal and water are required.
For hydro power station, plenty source of water and big dams are required. But where all these facilities are not available, such as no easy way of coal transportation and no scope of constructing dam, there diesel plant is established.
Diesel power plants are also popularly used as standby supply of different industries, commercial complexes, hospitals, etc. During power cut, these diesel power generators are run to fulfill required demand.
Advantages of Diesel Power Station This is simple in design point of view. Required very small space. It can also be designed for portable use. It has quick starting facility, the small diesel generator set can be started within few seconds. Cooling is easy and required smaller quantity of water in this type power station.
Initial cost is less than other types of power station. Thermal efficiency of diesel is quite higher than of coal. Disadvantages of Diesel Power Station As we have already mentioned, the cost of diesel is very high compared to coal. This is the main reason for which a diesel power plant is not getting popularity over other means of generating power.
In other words the running cost of this plant is higher compared to steam and hydro power plants. The plant generally used to produce small power requirement. Cost of lubricants is high. Maintenance is quite complex and costs high. Plant does not work satisfactorily under overload conditions for a longer period.
Different Components of Diesel Power Station In addition to diesel generator set or DG set there are many other auxiliaries attached to at diesel power station. Fuel Supply System In fuel supply system there are one storage tank strainers, fuel transfer pump and all day fuel tank.
Storage tank where oil in stored. This oil then pump to dry tank, by means of transfer pump. During transferring from main tank to smaller dry tank, the oil passes through strainer to remove solid impurities.
From dry tank to main tank, there is another pipe connection. This is over flow pipe. This pipe connection is used to return the oil from dry tank to main tank in the event of over flowing. From dry tank the oil is injected in the diesel engine by means of fuel injection pump.
Air Intake System This system supplies necessary air to the engine for fuel combustion. It consists of a pipe for supplying of fresh air to the engine.
Filters are provided to remove dust particles from air because these particles can act as an abrasive in the engine cylinder. Exhaust System The exhaust gas is removed from engine, to the atmosphere by means of an exhaust system.
A silencer is normally used in this system to reduce noise level of the engine. Cooling System The heat produced due to internal combustion, drives the engine. But some parts of this heat raise the temperature of different parts of the engine. High temperature may cause permanent damage to the machine.
Hence, it is essential to maintain the overall temperature of the engine to a tolerable level.Power Generation/Diesel Power. From Wikiversity Power Generation. Jump to navigation Jump to search.
Review: Lesson 3. The previous lesson was about the hydro power station. The student is expected to remember the following from the lesson 3: However, diesel power plants emit green house gases that pollute the environment .
