Document Type and Number:
WIPO Patent Application WO/2023/093304
Kind Code:
A1
Abstract:
The present invention relates to the technical field of discharge control of internal combustion locomotives, and in particular to an emergency discharge control method for a main and auxiliary integrated internal combustion locomotive, comprising: S1, when a discharge loop fault occurs in a locomotive having a main and auxiliary integrated structure, and when a TCMS determines that a main generator stops generating power and the TCMS is in normal communication with an auxiliary converter unit and an auxiliary inverter, manually selecting, by means of a display screen, to enter an emergency discharge working mode; and S2, after entering the emergency discharge working mode, the TCMS sending an emergency discharge instruction to the auxiliary converter unit and the auxiliary inverter. According to the present invention, when a fault occurs in a discharge device or discharge loop of the internal combustion locomotive having the main and auxiliary integrated structure, the TCMS controls an auxiliary system to enter the emergency discharge mode to quickly discharge a voltage in a main loop, so that rapid and safe discharge is realized, and personal safety is ensured; meanwhile, after the discharge fault, a special control strategy is used to ensure the operation of the locomotive as much as possible, so that a locomotive failure caused by a discharge loop fault is avoided.
