Question:

what is diesel power plant or station & how it is work?

Electrical Engeenearing

Answer:

A diesel power plant is a stationary installation incorporating one or more diesel generator sets with controls and switchgear. Diesel plants are usually used as emergency backup systems for military installations, hospitals, and other vital installations that depend on reliable electric power. There are also diesel power plants that are the only power supply for remotely located installations and communities; for example, remote radar stations and island resort towns. In a diesel plant, there are one or more diesel generator sets, consisting of a diesel engine and a suitable generator. A typical arrangement would involve three generators of which any two can handle the peak load while the third can be held as a standby unit or dismantled for major maintenance at intervals. There will be a switchyard that contains the electrical contactors and safety devices for connecting the generators to the grid as needed, and there will be control panels for the individual generators, as well as synchronizing gear to keep the generators in phase. In many installations these controls are computerized and can be operated and monitored at a distance over the internet or other communications arrangement. Also, there will be arrangements for handling the fuel required by the engines. Often there is a large tank and separate day tanks for each engine. This type of arrangement helps ensure that the entire supply is not lost in case the fuel plumbing or day tank for one generator set springs a leak.
