Introduction of diesel generator set

Diesel generator set is a type of AC power supply equipment in self-supplied power station. It is a small independent power generation equipment that uses an internal combustion engine as power to drive a synchronous alternator to generate electricity.

Modern diesel generator sets are composed of diesel engines, three-phase AC brushless synchronous generators, control boxes (screens), cooling water tanks, couplings, fuel tanks, mufflers, and public bases. The flywheel shell of the diesel engine and the front end cover of the generator are directly connected in the axial direction by a shoulder positioning, and a cylindrical elastic coupling is used to directly drive the rotation of the generator. The connection method is fixed by screws to make the two They are connected into a steel body to ensure that the concentricity of the crankshaft of the diesel engine and the rotor of the generator is within the specified range.

The diesel generator set is composed of an internal combustion engine and a synchronous generator. The maximum power of the internal combustion engine is limited by the mechanical load and thermal load of the parts and is called the rated power. The rated power of the AC synchronous generator refers to the rated speed. During long-term continuous operation, the rated power output is usually called the matching ratio between the rated power output of the diesel engine and the rated power output of the synchronous alternator.
