What is a diesel generator? In-depth look at everything you need to know before choosing one.

 

Diesel Generator is a device that produces electricity using energy from diesel fuel, which is suitable for use as a backup power system or even as a primary power source in remote areas where there is no access to electricity.

Working principle of diesel generator.

Diesel Generator has the overall working principle that when the engine burns fuel, it will rotate the alternator shaft to produce electricity, which can be used as backup power or the main power supply as needed.

• Diesel Engine: The diesel engine burns diesel fuel to create mechanical energy.
• Alternator converts mechanical energy from the engine into electrical energy.
• Control System checks the working status with protection system in case of overload, overheating or any working problem.
• Cooling system and lubrication system help the engine to work continuously and not overheat.

Types of diesel generators and proper selection.

Types of diesel generators and proper selection.

Diesel generators can be classified into many types, depending on the purpose of use, installation area, and energy requirements of each location. They can be divided into 2 main types: installation type and power supply type, as follows.

1. Divided by installation type.

Portable (Portable Diesel Generator) Small, compact machine with wheels or handles, suitable for temporary use, such as for temporary construction sites, shops during booths, or houses in areas where electricity is not available. Suitable for small loads such as light bulbs, fans, computers, or basic electrical appliances.

Stationary Diesel Generator: Medium to large sized units that are installed at a fixed location, usually with a soundproof canopy and better cooling system. Suitable for establishments that requires continuous backup power, such as factories, large office buildings, hotels, hospitals, or warehouses.

2. Divided by power supply format.
Standby Generator (Backup Generator) works only when the main power system is out by connecting to the main power system through the ATS (Automatic Transfer Switch) system.

The machine will start automatically when there is a power outage. It is suitable for places that require continuous electricity for a short period of time, such as office buildings, department stores, or residences.

Prime Power Generator (intermittent primary power source) can be used continuously for many hours. Suitable for areas with inconsistent electricity access or no mains electricity at all, such as rural areas, long-term construction sites, rural greenhouses, and outdoor activities that use a lot of electricity.

Continuous Power Generator (Continuous primary power source) provides power 24 hours a day without interruption, suitable for high-priority loads such as data centers production systems in heavy industrial plants, mines or large water pumping stations where electricity is not possible even for a second.

Advantages of diesel generators compared to other types.

Many people may wonder why diesel generators are more popular than other systems. Here are some of their outstanding advantages.
1. Durability and long service life. Diesel engines have a strong structure and last longer than gasoline systems, making them suitable for heavy-duty and continuous use.
2. Save fuel Diesel provides more energy per liter of fuel, resulting in lower electricity production costs.
3. Excellent load Diesel generators can supply continuous power without any drop, so the system does not interrupt like some systems that use gas or other energy.
4. Easy maintenance: Although diesel engines are large, maintenance is systematic and has high standards.

Limitations and maintenance of diesel generators.

Of course, despite their many advantages, diesel generators do have some limitations that should be considered, with the most common being noise. Diesel generators are noisy when operating. The generator will be quite noisy, need sound insulation, and release smoke and pollution, so need to install proper ventilation and exhaust system.

Examples of appropriate selection.

• Hotels/Condominiums should use medium to large Standby machines installed with ATS systems so that customers or residents do not feel the impact when the power goes out.
  Construction site / Farm / Temporary work Suitable for portable or permanent Prime Power depending on the duration of the project and the load used.
  Industrial plants / Data centers / Hospitals require large Continuous Power with remote control systems and ATS/AMF systems to ensure that the system does not trip even in an emergency.
  

Choosing a diesel generator design and installation service.

For entrepreneurs or organizations looking for backup power solutions, choosing a company with experience and full service is the best answer. The services should include.
Site survey: The engineer will analyze the electrical load, environment and specific customer requirements.
Custom design, design the generator, ATS system or automatic start system to suit the area and budget.
Standard installation according to engineering, with soundproofing and ventilation systems.
After-sales maintenance. We have a technicians ready to provide inspection, maintenance, spare parts replacement services and provide advice and training for customer staff.

Summary of diesel generators.
Diesel generators are devices that produce electricity using energy from diesel fuel. They have various forms of power supply. They can be used as a backup power supply or as a primary, intermittent or continuous power source. You can choose the one that is most suitable.
