How Does Diesel Genset Generate Electricity

Aug. 14, 2021

Diesel generator set is a small power generation equipment, which refers to the power machinery that uses diesel as fuel and diesel engine as prime mover to drive the generator to generate electricity. The whole diesel genset is generally composed of diesel engine, alternator, control box, fuel tank, starting and control battery, protection device, emergency cabinet and other components.

 

Diesel generator set is a type of AC power supply equipment of self owned power station. It is a small independent power generation equipment, which uses internal combustion engine as power to drive synchronous alternator to generate electricity. When brushless synchronous alternator is installed coaxially with the crankshaft of the diesel engine, the rotation of the diesel engine can be used to drive the rotor of the generator. Using the principle of "electromagnetic induction", the generator will output induced electromotive force and generate current through the closed load circuit.

 

The diesel engine drives the alternator to convert the energy of diesel into electric energy.

In the cylinder of the diesel engine, the clean air filtered by the air filter is fully mixed with the high-pressure atomized diesel injected by the fuel injection nozzle. Under the upward extrusion of the piston, the volume is reduced and the temperature rises rapidly to reach the ignition point of the diesel. When diesel oil is ignited, the mixed gas burns violently, and the volume expands rapidly, pushing the piston down, which is called "work". Each cylinder works sequentially in a certain order, and the thrust acting on the piston becomes the force to push the crankshaft through the connecting rod, so as to drive the crankshaft to rotate.

Diesel generator set is a type of AC power supply equipment of self owned power station. It is a small independent power generation equipment, which uses internal combustion engine as power to drive synchronous alternator to generate electricity.

 

Modern diesel generator set consists of diesel engine, three-phase AC brushless synchronous generator, control box (panel), cooling water tank, coupling, fuel tank, muffler and public base. The axial direction of the flywheel housing of the diesel engine and the front end cover of the generator are directly connected by shoulder positioning, and the cylindrical elastic coupling is used to directly drive the rotation of the generator by the flywheel. The connection mode is fixed together by screws to connect the two into a steel body, so as to ensure that the concentricity of the crankshaft of the diesel engine and the rotor of the generator is within the specified range.

 

In order to reduce the vibration of the unit, shock absorbers or rubber damping pads are usually installed at the connection between the main components such as diesel engine, generator, water tank and electrical control box and the common base.

 

Diesel generator set is a kind of small and medium-sized power generation equipment. It has the advantages of flexibility, less investment and convenient start-up. It is widely used in various departments such as communication, mining, road construction, forest area, farmland irrigation, field construction and national defense engineering. Diesel generator set is also an AC power supply equipment in self provided power station.

 

Diesel generator set is suitable for occasions where the municipal power grid cannot be transmitted to Communication Bureau stations, mining areas, forest areas, pastoral areas and national defense projects. It is required to supply power independently as the main power supply for power and lighting. For areas with municipal power supply, units that require high reliability of power supply, do not allow power failure and can quickly restore power supply within a few seconds, such as important departments such as communication, bank, hotel and airport, can be used as emergency standby power supply, and can quickly provide stable AC power supply in case of municipal power failure.

 

The main requirements for diesel generator set are that it can automatically start power generation at any time, operate reliably, ensure the voltage and frequency of power supply, and meet the requirements of electromechanical equipment.

 

After you learn above information, believe you have know more about diesel genset. Diesel genset is an important power supply equipment to the place where is short of electricity.
