Generator

General

Diesel generating sets are used in places without connection to the power grids, as emergency power-supply if the grid fails, as well as for more complex applications such as peak-lopping, grid support and export to the power grid. Sizing of diesel generators is critical to avoid low-load or a shortage of power and is complicated by modern electronics, specifically non-linear loads. An engine-generator is the combination of an electrical generator and an engine mounted together to form a single piece of self-contained equipment.

Many different versions of engine-generators are available - ranging from 30 kW to 1,500 kW. The primary advantage of engine-generators is the ability to independently supply electricity, allowing the units to serve as backup power solutions.

The packaged combination of a diesel engine, an alternator and various ancillary devices - such as base, canopy, sound attenuation, control systems, circuit breakers, jacket water heaters and starting system, is referred to as a "Generator Set" or a "Gen Set" for short.

Set sizes range of 30 kW (single phase) for homes, small shops and offices with the larger industrial generators from 8 kW (11 kVA) up to 2,000 kW (2,500 kVA three phase) used for large office buildings, factories, skyscrapers, hospitals, and hotels.

Diesel generators, sometimes as small as 200 kW (250 kVA) are widely used not only for emergency power, but also many have a secondary function of feeding power to utility grids either during peak periods, or periods when there is a shortage of large power generators.
