The diesel generator set is a combination 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 generator set and the rated power output of the synchronous alternator.
Diesel generator set is a type of AC power supply equipment of 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. By installing the brushless synchronous alternator coaxially with the diesel engine crankshaft, the rotor of the generator can be driven by the rotation of the diesel generator set. Using the principle of “electromagnetic induction”, the generator will output induced electromotive force, which can be achieved through a closed load circuit. Generate current.
As a power generation equipment, a diesel generator set uses diesel fuel as the fuel, and the diesel engine is the prime mover to drive the generator to generate electricity. The complete set is generally composed of diesel engine, generator, control box, fuel tank, storage battery for starting and control, protection device, emergency cabinet and other components. Diesel generator sets are non-continuous operation power generation equipment. If they operate continuously for more than 12 hours, their output power will be about 90% lower than the rated power. If the user needs to use it uninterrupted for a long time, it needs to be equipped with a commonly used generator set, that is, the generator should take into account the power drop of the long-term working unit.
