This article mainly introduces the basic structure of diesel generator set. If you are interested, take a few minutes to read it. Hope it is helpful.
The basic
structure of diesel generator set is composed of diesel engine and generator.
Diesel engine is used as power to drive generator to generate electricity. Nowadays, the diesel generator is
widely used in many fields, such as mines, railways, field sites, road traffic
maintenance, factories, enterprises and hospitals and so on.
Diesel
generator set is generally composed of four parts: diesel engine , AC
synchronous generator, control panel and common base. The image below will
help you understand better.
Structure of Diesel Generator Set
Diesel
Engine
Diesel
Engine is a compression ignition engine with diesel fuel. It is widely used as
the prime mover for electrical power generating unit in the range from 20 KW to
5000 KW.
Diesel
engine is classified in different ways. It can be classified in accordance to
its number of strokes, cooling way, air admission way, cylinder number,
cylinder arrangement and rotation speed. The detailed information is as
follows:
1).
Classification according to the number of strokes, there are two main types,
four strokes and two strokes. However,
four stroke diesel engine is more widely used.
2).
Classification according to the cooling way, there are water-cooled and
air-cooled two types. However, water-cooled diesel engine is used more
widely.
3).
Classification according to the air admission way, there are non-supercharging
(naturally aspirated) and supercharging mode two types.
4).
Classification according to the cylinder number, there are horizontal bar,
parallel bars and multi-cylinder diesel engine.
5).
Classification according to the cylinder arrangement, there are in- line type,
V type, horizontal type and opposite type diesel engine.
6).
Classification according to the rotation speed, diesel engines are built to
rotate at either low speed, medium speed or at high speed.
Alternator is an electrical generator that converts mechanical
energy into electrical energy in the form of alternating current.
A AC generator is a device
which converts mechanical energy into electrical energy. The simplest practical
generator consists of a rectangular coil rotating in a uniform magnetic field.
The magnetic field is usually supplied by a permanent magnet.
3) Control
Panel
The main
purpose of control panel is to distribute the electric energy output by diesel
generator set to users’ load or electric equipment through control panel.
Generally,
it is equipped with voltmeter, ammeter, frequency and control switches related
electrical equipment on the control panel. It aims to show the operation of
the generator set and to maintain the voltage stability of the genset under the
condition of load change.
Common
types of diesel genset
There are
many types of diesel generator set, which can
be divided into the following types according to its sructure, control mode and
protection function.
1) Basic type genset
2) Automatic
starting genset
3) Micro
control automation genset
