In this blog post, we will delve into the key features and advantages of diesel generators to help you make an informed buy for your power backup requirements.
what are diesel generators
Diesel generator is a kind of small power generation equipment, which refers to the power machinery that uses diesel as fuel and a diesel engine as the prime mover to drive the generator to generate electricity. The entire unit generally consists of a diesel engine, generator, control box, fuel tank, battery for starting and control, protection device, emergency cabinet and other components.
It can be used for daily power generation and emergency power generation in various homes, offices, large, medium and small enterprises.
Working principle of diesel generator
In short, the diesel generator drives the generator.
In the cylinder, the clean air filtered by the air filter is fully mixed with the high-pressure atomized diesel fuel injected from the injector. Under the upward squeeze of the piston, the volume shrinks and the temperature rises rapidly, reaching the ignition point of the diesel fuel. The diesel is ignited, the mixed gas burns violently, expands rapidly in volume, and pushes the piston downward, which is called ‘work’.
Each cylinder performs work in a certain order, and the thrust acting on the piston becomes a force that drives the crankshaft to rotate through the connecting rod, thereby driving the crankshaft to rotate. By installing the brushless synchronous alternator coaxially with the crankshaft of the diesel generator, the rotation of the diesel generator can be used to drive the rotor of the generator. Using the principle of ‘electromagnetic induction’, the generator will output an induced electromotive force through a closed load circuit. can produce current.
Only the most basic working principle of the generator set is described here. In order to obtain usable and stable power output, a series of diesel generators and generator control, protection devices and circuits are also required.
Main uses of diesel generators
Power supply for daily use
Although the power of diesel generator sets is low, due to their small size, flexibility, lightness, complete facilities, and easy operation and maintenance, they are widely used in mining, railways, field construction sites, road traffic maintenance, as well as factories, enterprises, hospitals and other departments .
Emergency Power Supply
Diesel generator sets are used where there is no connection to the grid, or as emergency power in the event of a grid failure, as well as for more complex applications such as peak tripping, grid support and grid output.
Diesel generator application scenarios
home, shop, office
For homes, small shops and offices, equipment sizes range from 8 to 30 kW (also 8 to 30 kVA single phase)
factory
Large industrial generators from 8 kW (11 kVA) to 2,000 kW (2,500 kVA three-phase) complexes. The 2,000 kW unit can be installed in a 12 meter ISO container, with fuel tanks, controllers, power distribution equipment and all other equipment required to operate as a stand-alone power station or as backup for grid power.
small power station
Combinations of these modules are used in small power stations, and each module uses 1 to 20 units and can be combined into hundreds of power modules. In these larger sizes, the power modules (engine and generator) are brought individually onto the trailer and connected together with large and control cables to form a fully synchronized power plant. There are also many options to suit specific needs, including control panels for automatic starting and power paralleling, ventilation for stationary or mobile applications, fuel supply systems, exhaust systems and more.
Advantages of diesel generators
Diesel generator sets are considered the preferred form of backup and emergency power. At present, although there are many other means of solving backup and emergency power needs, such as UPS and dual-circuit power supply, they cannot replace the role of diesel generator sets. In addition to price factors, the main reason is that diesel generator sets serve as backup and emergency power supplies. Power supply, higher reliability. As power generation equipment, diesel generator sets have some unique advantages:
- Relatively small in size, flexible and convenient, easy to move
- Easy to operate, simple and easy to control
- Energy raw materials (fuel) are widely available and easy to obtain
- Less one-time investment
- Quick start, can supply power and stop power quickly
- The power supply is stable and the quality of power supply can be improved through technological improvements.
- Point-to-point direct power supply can be provided to the load
- It is less affected by various natural climates and geographical environments and can generate electricity around the clock.
