A diesel generator is the combination of a diesel motor with an electrical generator to produce electric power. This is a certain situation of engine generator. A diesel compression-ignition engine is usually developed to operate on diesel fuel, however some kinds are adjusted for other liquid fuels or natural gas.
Diesel generating collections are utilized in position without connection to a power grid, or as emergency situation power supply if the grid falls short, along with for even more complicated applications such as peak-lopping, grid support, and also export to the power grid.
Correct sizing of diesel generators is crucial to avoid low load or a scarcity of power. Sizing is made complex by the characteristics of modern-day electronics, specifically non-linear lots. In size varieties around 50 MW and above, an open cycle gas wind turbine is more efficient at full lots than a range of diesel motor, and far more small, with comparable funding prices; but for routine part-loading, even at these power degrees, diesel selections are sometimes chosen to open cycle gas turbines, because of their exceptional efficiencies.

The packaged combination of a diesel engine, a power set, and also various supplementary devices (such as base, canopy, audio depletion, control systems, breaker, jacket water heaters, as well as beginning system) is described as a “producing set” or a “genset” for brief.
Diesel generators are not only for emergency power, but might likewise have an additional feature of feeding power to utility grids either throughout peak periods, or durations when there is a shortage of large power generators. In the UK, this program is run by the national grid and is called STOR.
Ships usually also use diesel generators, often not only to provide auxiliary power for lights, fans, winches and so on, but additionally indirectly for primary propulsion. With electric propulsion the generators can be put in a convenient setting, to enable more freight to be carried. Electric drives for ships were developed prior to World Battle I. Electric drives were specified in several warships developed during World War II because making capacity for large reduction gears remained in short supply, compared to capacity for manufacture of electric equipment. Such a diesel-electric setup is also used in some huge land vehicles such as railway engines.
