Problems solved by technology

[0002] The traditional internal combustion traction system is fully powered by a diesel engine and cannot use regenerative braking energy like an electric vehicle with a VVVF (Variable Voltage and Variable Frequency) inverter. When the traction motor is in braking mode , the generated energy can only be consumed in the form of heat energy, resulting in energy waste

Abstract

The invention discloses an internal combustion traction system, which comprises a diesel engine power device, a super capacitor and a control module, wherein the diesel engine power device is used foroutputting direct current to supply power to a converter; the super capacitor is used for outputting direct current to supply power to the converter when a traction motor executes a traction mode, and is also used for storing regenerative braking energy when the traction motor executes a braking mode; the converter is used for converting direct current output by the diesel engine power device andthe super capacitor into alternating current to supply power to corresponding loads; the control module is used for controlling the traction motor to execute the traction mode when receiving a traction instruction, and is also used for controlling the traction motor to execute the braking mode when receiving a braking instruction. In the invention, the converter is powered by two path of parallelinput, the electric energy output by power generation of the diesel engine through a rectifier is used as the main power input, and the energy stored by the super capacitor is used as the secondary power input. Compared with the prior art, the regenerative braking energy is stored by the super capacitor, the power is provided for the converter, and the energy is saved.

Description

technical field [0001] The present application relates to the field of internal combustion traction systems, in particular to an internal combustion traction system. Background technique [0002] The traditional internal combustion traction system is fully powered by a diesel engine and cannot use regenerative braking energy like an electric vehicle with a VVVF (Variable Voltage and Variable Frequency) inverter. When the traction motor is in braking mode , The generated energy can only be consumed in the form of heat energy, resulting in energy waste. [0003] Therefore, how to provide a solution to the above technical problems is a problem that those skilled in the art need to solve at present. Contents of the invention [0004] The purpose of this application is to provide an internal combustion traction system, the converter is powered by two parallel inputs, the electric energy output by the diesel engine through the rectifier is used as the main power input, and the ...
