How does a Diesel Generator Set work?

July 06, 2022

An electric generator (typically an alternator) and a diesel engine are combined to create a diesel generator, commonly referred to as a diesel genset. This is a special instance of an engine generator. Most diesel compression-ignition engines are made to run on diesel fuel, although certain models can also run on natural gas or other liquid fuels.

Diesel generator sets are utilized for more sophisticated applications including peak-lopping, grid support, and transfer to the power grid as well as in areas that are not connected to a power grid or as an emergency power source in the event that the grid goes down.

To prevent low-load or a lack of power, the diesel generator set must be properly sized. The peculiarities of contemporary electronics, particularly non-linear loads, make sizing challenging. An open cycle gas turbine is more productive at full load and significantly handier than a diesel engine array in size ranges of 50 MW and above, with roughly equivalent capital costs; however, for routine part-loading, even at these power levels, diesel engine arrays are sometimes favored to open cycle gas turbines owing to its high efficiencies.

A genset is commonly composed of steel, stainless steel, or aluminum and enclosed in a sound-dampening structure to minimize noise to the surrounding areas. Corrosion resistance and efficient engine cooling management are essential for this cabin. An anti-vibration system is built into the base frame, which may also house the gasoline tank or a separate tank. In case of energy needs to be switched between the primary source and an auxiliary one, further components include a control panel and an automatic transfer switch.

How does a Diesel Generator Set work?

A prime mover, which is commonly an engine, and an alternator are combined to form a diesel generator set. The chemical energy of diesel is transformed into mechanical energy by an engine. The alternator rotor is spun using that mechanical energy, which causes mechanical energy to be transformed into electrical energy. The rotor and stator are the two major components of an alternator. Through the electromagnetic induction phenomenon, rotating the alternator rotor via the magnetic field between the rotor and stator generates a voltage on the alternator stator. Electrical current flows and the generator generates electricity when the voltage on the stator is coupled to a load. As result, the diesel generator set produces transportable energy sources.

Larger industrial generators with set sizes ranging from 8 kW (11 kVA) up to 2,000 kW (2,500 kVA three-phase) are used for big office buildings, industries, and other industrial facilities. Set sizes vary from 8 to 30 kW (also 8 to 30 kVA single phase) for residences, small businesses, and offices. With the fuel tank, controllers, power transmission equipment, and all other necessary equipment to function as an independent power station or as a standby backup to grid power, a 2,000 kW set can be placed in a 40 ft (12 m) ISO container. These generators, also known as power modules, are mounted on substantial triple axle trailers that weigh at least 85,000 pounds (38,555 kg).

Small power plants use a mixture of these modules. These plants may use one to twenty units per power section, and these sections can be merged to use hundreds of power modules. In these higher capacities, the engine and generator are transported to the installation site individually and joined to form a full synchronized power plant using substantial cables and a control cable. Additionally, there are a variety of solutions available to meet particular requirements, such as control systems for AutoStart and main supply paralleling, acoustic canopies for stationary or portable applications, ventilation systems, fuel delivery systems, exhaust systems, etc.

Diesel generators can serve a dual purpose of supplying power to utility grids at periods of peak demand or when there is a lack of large power generators, in addition to providing emergency power. This initiative, known as STOR in the UK, is operated by the national grid.

Diesel generators are also frequently used by ships, sometimes serving both as supplemental power sources for things like lighting, fans, and winches as well as indirect main propulsion. The generators can be positioned conveniently with electric propulsion, allowing for the transportation of greater freight.


Diesel Generator Size

When choosing generating sets, consideration is given to the electrical load that will be supplied, as well as its kW, kVA, var, harmonic content, surge currents (such as motor starting current), and non-linear loads. Environmental factors (such as altitude, temperature, and exhaust emission standards) and anticipated duties (such as emergency, prime, or continuous power) must also be taken into account.

At Junvoch, we have software that, by simply entering site parameters and connected electrical load characteristics, will carry out the challenging sizing calculations.
