Diesel generator sets

Diesel generator sets (DGS)- These are autonomous sources of electricity that convert the energy of diesel fuel into electricity. They are widely used as a main or backup power source in various applications, from private homes to industrial plants. Selecting the right diesel generator set depends on many factors, including power requirements, operating conditions and budget.

What is a diesel generator set?

Diesel generator setsare complex equipment consisting of a diesel engine, an alternator, a control system and various auxiliary systems (cooling, lubrication, exhaust, etc.). The diesel engine drives a generator, which produces electricity.

Operating principle

Operating principlediesel generator setis based on the conversion of the chemical energy of diesel fuel into the mechanical energy of rotation of the engine crankshaft, and then into electrical energy in the generator. The process includes the following steps:

1. Supply of diesel fuel to the engine cylinders.
2. Combustion of fuel and formation of gases pushing the pistons.
3. Rotation of the crankshaft.
4. Transmission of crankshaft rotation to the generator rotor.
5. Generation of electrical energy in the stator windings of the generator.

Applications

Diesel generator setsin demand in a variety of industries:

• Industry:providing electricity to manufacturing enterprises, warehouses, construction sites.
• Medicine:guaranteed power supply to hospitals, clinics, laboratories.
• Telecommunications:uninterrupted operation of cellular base stations and data centers.
• Construction:power supply for power tools and lighting at construction sites.
• Agriculture:ensuring the operation of pumping stations, irrigation systems, livestock complexes.
• Private use:backup power supply for private houses and cottages.

Advantages and disadvantages of diesel generator sets

Like any equipment,diesel generator setshave their advantages and disadvantages.

Benefits:

• High reliability:DGSs are capable of operating for a long time without interruption.
• High Power:DGSs can provide electricity to facilities with high energy consumption.
• Autonomy:DGSs do not depend on centralized power supply networks.
• Relatively low cost of electricity:Compared to gasoline generators, diesel generators consume less fuel per unit of electricity generated.
• Durability:With proper maintenance, diesel generator sets can serve for many years.

Disadvantages:

• High noise level:The operation of diesel generator sets is accompanied by significant noise, which requires the use of noise-protective enclosures.
• Emissions of harmful substances:Diesel generators emit combustion products of diesel fuel into the atmosphere, which requires compliance with environmental standards.
• Regular maintenance required:Diesel generators require regular replacement of oil, filters and other consumables.
• Higher cost compared to gasoline generators:The initial investment for diesel generator sets is usually higher than for gasoline generators.

How to choose a diesel generator set?

Choosing the right onediesel generator set– a responsible task that requires taking into account many factors. Yuke (Shandong) Electrical Technology Co.,Ltdvoyoko.ruoffers a wide range of diesel generator sets that meet a variety of needs. When choosing, you should pay attention to the following parameters:

Determining the required power

The first and most important step is to determine the required powerdiesel generator set. To do this, it is necessary to sum up the power of all electricity consumers that will be connected to the diesel generator set and add a reserve of 20-30%.

When calculating power, it is necessary to take into account the starting currents of some electrical appliances (for example, electric motors, pumps, compressors), which can significantly exceed their rated power.

Type of execution

Diesel generator setscan be made in various versions:

• Open version:DGSs do not have a protective casing and are intended for installation in enclosed spaces.
• Boned version:DGSs have a protective casing that reduces noise levels and protects equipment from external influences.
• Container version:The diesel generator sets are installed in a sea container, which ensures mobility and protection from vandalism.

Startup type

There are two main types of launchdiesel generator sets:

• Manual start:The diesel generator set is started manually using a starting cord or handle.
• Automatic start (AVR):The diesel generator set starts automatically when there is a power failure in the main network.

Manufacturer

Manufacturer selectiondiesel generator set– an important aspect that determines the reliability and durability of equipment. It is recommended to choose diesel generator sets from well-known and trusted manufacturers such as Cummins, Perkins, Volvo Penta and others.

Maintenance of diesel generator sets

To ensure reliable and durable performancediesel generator setMaintenance must be carried out regularly. Service includes:

• Changing oil and filters.
• Checking and adjusting the fuel system.
• Checking and adjusting the cooling system.
• Checking and adjusting the lubrication system.
• Checking and adjusting the exhaust system.
• Checking and adjusting the electrical part.

The frequency of maintenance depends on the intensity of usediesel generator setand is indicated in the instruction manual.
