Introduction: Diesel Power station
A Diesel power station(also known as Stand-by power station) uses a diesel engine as prime mover for the generation of electrical energy.
This power sattion is generally compact and thus can be located where it is actually required. This kind of power station can be used to produce limited amounts of electrical energy. In most countries these power stations are used as emergency supply stations.
Operation
The diesel burns inside the engine and the combustion process causes rotational mechanical energy that turns the engine shaft and drives the alternator. The alternator inturn, converts mechanical energy into electrical energy.
This type of electricity generating power station will probably be used a long time into the future, due to a need for reliable stand-by electrical source for emergency situations.
Advantages v/s Disadvantages
Advantages
1. Simple design & layout of plant
2. Occupies less space & is compact
3. Can be started quickly and picks up load in a short time
4. Requires less water for cooling Cost of lubrication very high
5. Overall cost is cheaper than that of Steam Power plant of same size
6. Requires no Operating staff .
Disadvantages
1. High running charges due to costly price of Diesel
2. Plant does not work efficiently under prolonged overload conditions
3. Generates small amount of power
4. Thermal efficiency better that of Steam Power plant of same size
5. Maintenance charges are generally high
