Internal combustion motor train unit hybrid power supply power system and power supply method

Abstract

The invention discloses an internal combustion motor train unit hybrid power supply power system and a power supply method. During operation of the train, an energy management module can transmit a level signal of a train controller to an inverter, and the inverter sets envelope lines between the train speed traction as well as the grain speed and regenerated power according to the received levelsignal of the train controller and according to the power performance of the power system in advance and controls a traction motor to exert the corresponding moment; meanwhile, the inverter calculatesthe current actual required power according to the input end acquisition voltage and current values and transmits the required power to the energy management module, the energy management module calculates and transmits the required output power to a rectifier according to the power which can be exerted by a supercapacitor at present, and the rectifier controls a power pack to output the corresponding power according to the command requirement of the energy management module. The internal combustion motor train unit hybrid power supply power system is simple in structure and reliable in control, can improve the power performance of the train and can improve the transportation ability of the train.

Description

technical field [0001] The invention relates to an internal electric power supply system of a diesel train set, in particular to a hybrid power supply system and a power supply method of a diesel train set. Background technique [0002] After years of development, traditional diesel multiple units have made great contributions to the development of human civilization and created incalculable direct or indirect economic benefits. However, with the rapid development of rail transit technology in recent years, people are increasingly aware of the harm that traditional internal combustion vehicles bring to the human environment. The deteriorating air quality caused by the operation emission of the traditional diesel train power system and the gradual scarcity of oil resources, the urgency of environmental protection and the pressure of the increasing shortage of oil reserves force people to consider the power system of the diesel train unit, and the demand is optimal s solution...
