Dual-motor power generation system

Abstract

The invention relates to a dual-motor power generation system which comprises an internal combustion engine, a planet wheel mechanism, a first power generator, a second power generator, a first brake, a second brake and a power generation control unit. A rotor part of the second generator is connected with a gear ring of the planet wheel mechanism, the first brake is connected with the outer shell, and the second brake is connected with the outer shell. By the adoption of the dual-motor power generation system, the range and distribution of the efficient working region of the internal combustion engine power generation system can be expanded, so that the dynamic economic working condition coverage degree of the power generation system is improved, and especially the economical efficiency problem of the high-power internal combustion engine power generation system in the continuous low-power power generation demand state is solved. Meanwhile, one machine can be used for multiple purposes, namely, one internal combustion engine is used for providing multiple power sources, and the equipment utilization rate is increased.

Description

technical field [0001] The invention relates to the technical field of internal combustion engine power generation systems, in particular to a dual-motor power generation system. Background technique [0002] The current status of the internal combustion engine power generation system is: the basic structure of an internal combustion engine driving a generator, the power of the power generation system is directly and linearly determined by the power generation capacity and load demand, the high efficiency area of ​​the internal combustion engine power generation system is limited and basically fixed, and it is difficult to adjust dynamically, especially It is the problem of low-efficiency power generation under the condition of low power continuous demand. Under the condition of dynamic change of power generation demand, the economy of comprehensive power generation is poor, and the power generation system has a greater probability of operating in the low-efficiency working a...
