Multi-stage differential generator

Abstract

The multi-stage differential generator comprises an energy storage element, an inverter, a direct-current motor, a differential mechanism and an alternating-current generator which are connected in sequence, and direct current provided by the energy storage element is inverted into alternating current through the inverter and then supplied to the direct-current motor. According to the multi-stage differential generator, continuous power generation of the alternating-current generator is ensured by arranging the energy storage element, so that the problems that in the prior art, photovoltaic power generation is affected by weather and cannot generate power continuously, and the stability and the power generation efficiency are reduced are effectively solved; meanwhile, the differential mechanism is arranged, and the direct-current motor with the high rotating speed is used for driving the alternating-current generator with the large size, so that energy loss caused by the fact that the starting torque of the alternating-current generator is too large is avoided, the reliability of the alternating-current generator in the starting process and the rotating process is guaranteed, and then alternating current generated by the alternating-current generator can be directly applied.

Description

technical field [0001] The invention relates to the technical field of power generation equipment, in particular to a multi-stage differential speed generator. Background technique [0002] At present, there are thermal power generation, hydropower generation, photovoltaic power generation, etc. in the market, but the most electric energy still comes from thermal power generation. But the biggest disadvantage of thermal power generation is that the air pollution is particularly serious. Carbon emissions are also relatively serious, because thermal power generation has also caused international controversy many times over air pollution. The country has discovered that the kinetic energy of water flow can be converted into electrical energy, and hydropower stations have been established in many places in China, including the largest in the Three Gorges. But the cost of building a hydroelectric power station is higher than imagined, and it will take many years to recover the ...
