Description

Technical Field

[0001] The utility model relates to the technical field of generator sets, in particular to a dual-mode output generator set. Background Art

[0002] Generator Set is a complete set of mechanical equipment that converts other forms of energy into electrical energy. It consists of a power system, control system, silencer system, shock absorption system, exhaust system, etc. It is driven by a turbine, steam turbine, diesel engine or other power machinery. It converts the energy generated by water flow, air flow, fuel combustion or nuclear fission into mechanical energy and transmits it to the generator, which then converts it into electrical energy and outputs it to the electrical equipment for use. Generators are widely used in industrial and agricultural production, national defense, science and technology, and daily life. In recent years, with the advancement of technology, as a high-quality choice for home emergency power supply and outdoor travel power supply, lightweight and portable small generator sets have also begun to enter the daily life of residents.

[0003] Traditional generator sets transfer energy through a single link of engine → generator → load. However, due to the characteristics of the engine, the best fuel consumption rate (g / kW·h) can only be achieved when the generator set is under a load of more than 75%. Under low load conditions (less than 75%), the fuel consumption rate will increase significantly, and may even be more than twice that of the best conditions. In actual use, it is very common for generator sets to be under low load conditions for a long time, resulting in a generally high overall fuel consumption rate for the generator set.
