File Name: construction and working principle of diesel generator .zip
The diesel engine is the workhorse in the generator. It burns diesel fuel, to create rotary motion which is used to turn the AC alternator.
Diesel engine , any internal-combustion engine in which air is compressed to a sufficiently high temperature to ignite diesel fuel injected into the cylinder , where combustion and expansion actuate a piston.
What is an Electric Generator and Its Working
Alternators or synchronous generators can be classified in many ways depending upon their application and design. According to application these machines are classified as-. Automotive type - used in modern automobile. Diesel electric locomotive type - used in diesel electric multiple units. Marine type - used in marine. Brush less type - used in electrical power generation plant as main source of power.
This article is for the design, materials, manufacture, testing, and commissioning of packaged stand-by diesel engine generators intended for permanent installation in industrial plants. Self-contained enclosure shall be provided for the diesel generator set. The enclosure shall be manufactured such that all part are accessible for inspection and minor maintenance without removal of the enclosure or enclosure roof. It shall include the following features:. The enclosure and all other items shall be designed and built by the supplier as an integral part of the entire diesel generator set, and shall perform without overheating in the environment specified. It shall be constructed of minimum gauge sheet metal, suitably reinforced to reduce vibration in the operating mode.
Generators are useful appliances that supply electrical power during a power outage and prevent discontinuity of daily activities or disruption of business operations. Generators are available in different electrical and physical configurations for use in different applications. In the following sections, we will look at how a generator functions, the main components of a generator, and how a generator operates as a secondary source of electrical power in residential and industrial applications.
A dc generator is an electrical machine which converts mechanical energy into direct current electricity.
A diesel generator DG also known as diesel genset is the combination of a diesel engine with an electric generator often an alternator to generate electrical energy. This is a specific case of engine-generator. A diesel compression-ignition engine is usually designed to run on diesel fuel , but some types are adapted for other liquid fuels or natural gas. Diesel generating sets are used in places without connection to a power grid , or 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. Proper sizing of diesel generators is critical to avoid low-load or a shortage of power. Sizing is complicated by the characteristics of modern electronics , specifically non-linear loads. In size ranges around 50 MW and above, an open cycle gas turbine is more efficient at full load than an array of diesel engines, and far more compact, with comparable capital costs; but for regular part-loading, even at these power levels, diesel arrays are sometimes preferred to open cycle gas turbines, due to their superior efficiencies.
A diesel generator is machinery that converts the chemical energy in diesel to electrical energy. It does this using a diesel engine and an AC alternator , coupled together. They also normally have a fuel tank, control panel and a radiator. You can review the major components of a diesel generator. You should read how the diesel engine works then how the AC alternator works. The diesel engine spins the alternator creating an AC electrical current.
Она посмотрела на вентиляционный люк и принюхалась. Но запах шел не оттуда, его источник находился где-то поблизости. Сьюзан посмотрела на решетчатую дверь, ведущую в кухню, и в тот же миг поняла, что означает этот запах. Запах одеколона и пота. Она инстинктивно отпрянула назад, застигнутая врасплох тем, что увидела. Из-за решетчатой двери кухни на нее смотрели .
