Energy-saving generator set

Abstract

The invention relates to an energy-saving generator set, which comprises a prime power engine, and also comprises a rectification generator, a speed regulation mechanism and an excitation regulator. The prime power engine is connected with the rectification generator to drag the rectification generator to generate direct current. The generator set is further internally provided with a control center which is used for receiving a voltage signal of the direct current generated by the rectification generator, adjusting the voltage signal of the rectification generator through the excitation regulator and adjusting the rotating speed of the prime power engine through the speed adjusting mechanism. One end of the excitation regulator is connected with the rectification generator and the other end is connected with the control center for stabilizing DC voltage generated by the rectification generator. The power frequency does not need to be stabilized at a stable rotating speed, and the frequency is determined by the inverter, so that the rotating speed can be freely changed without influencing the frequency, and the purpose of saving oil consumption can be achieved by reducing the speedduring light load.

Description

technical field [0001] The invention relates to the field of generator sets, in particular to an energy-saving generator set. Background technique [0002] At present, the general generator sets use power frequency generators. Since the frequency of the power frequency generators is constant, and in order to maintain a constant frequency, its speed must also be constant, and the speed of the generator set is basically fixed under light load and heavy load. , resulting in a significant increase in the fuel consumption ratio at light load, high fuel consumption and loud noise. my country uses a household electric voltage with a frequency of 50Hz and a voltage of AC220V, but some countries use a frequency of 60Hz and AC240V. The traditional generator set is in When used for export, the original engine speed must be increased by 20% to achieve a working frequency of 60Hz. This requires more accessories to be changed, and the engine will also be under greater pressure, which will i...

Problems solved by technology

[0002] At present, the general generator sets use power frequency generators. Since the frequency of power frequency generators is constant, and in order to maintain a constant frequency, its speed must also be constant. The speed of the generator set is basically fixed when it is light-loaded or heavy-loaded. , leading to a sharp increase in fuel consumption ratio at light loads, high fuel consumption, and high noise. Our country uses a household electrical voltage with a frequency of 50Hz and a voltage of AC220V, but some countries use a frequency of 60Hz and a voltage of AC240V. When used for export, the original engine speed must be increased by 20% to achieve a working frequency of 60Hz. This requires more accessories to be changed, and the engine is also under greater pressure, which will increase the cost
