Embodiment Construction

[0031] Such as figure 1 and figure 2 Shown, power system of the present invention comprises:

[0032] The energy management module is used to receive internal electric power packs, rectifiers, super capacitors, and inverter sub-modules to send their own working status, current voltage, current, actual available power, and current output power, and then calculate and perform energy management to achieve power system response It has the advantages of fast speed, strong power performance and high recovery of braking energy.

[0033] On the one hand, the internal electric power pack is connected to the energy management module through the MVB line, and the MVB network is used to send its own status and working parameters to the energy management module; Send its own capability parameters to the rectifier.

[0034] On the one hand, the rectifier is connected to the energy management module through the MVB line, and the MVB network is used to send its own status and working para...

Abstract

The invention discloses a hybrid power supply power system and a power supply method for an internal-combustion EMU. When the train is running, the energy management module sends the level signal of the train controller to the inverter. According to the power performance of the power system, set the envelope of train speed and traction force, train speed and regenerative braking force, and control the traction motor to exert the corresponding torque; at the same time, the inverter collects voltage and current values ​​according to the input terminal, Calculate the current actual required power and send the required power to the energy management module. The energy management module calculates and sends the required output power command to the rectifier according to the current power of the supercapacitor. The rectifier controls the power pack to output the corresponding power according to the command of the energy management module. The invention has simple structure and reliable control, can increase the power performance of the train and improve the transport capacity 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...
