Abstract

The invention discloses a train power supply system and method capable of automatically configuring power supply modes. The train power supply system comprises a first mode recognition unit, a first signal feedback unit, a first train power supply module, a second train power supply module, a first train power supply bus and a first train power supply socket assembly, wherein the first train powersupply module is connected with the first train power supply bus through a first contactor ACMK, and the second train power supply module is connected with the first train power supply bus through afirst contactor DCMK; the first train power supply bus supplies power to loads through the first train power supply socket assembly; and the first signal feedback unit transmits coupling information of the first train power supply socket assembly to the first mode recognition unit, and the first mode recognition unit controls the first contactor ACMK and the first contactor DCMK based on the coupling information. The train power supply system and method can automatically configure output power supply modes according to load types to guarantee power supply and load matching, guarantee power supply safety and guarantee high-requirement and high-reliability power supply to refrigerated container loads.

Description

technical field [0001] The invention relates to the technical field of train power supply, in particular to a train power supply system and method for automatically configuring a power supply system. Background technique [0002] AC drive passenger electric locomotives in my country are equipped with DC600V train power supply devices to provide DC600V power supply to passenger vehicles, and diesel passenger locomotives provide 3-phase AC380V power supply to vehicles by means of diesel locomotives plus electric cars. With the gradual increase of the electrification rate in our country, the distribution of electric locomotives is increasing. It is necessary that the existing high-power AC drive passenger electric locomotives can provide DC600V power supply and 3AC380V power supply to vehicles. [0003] In addition, with the improvement of domestic living standards, a large amount of food that needs to be refrigerated or frozen is transported to thousands of households from all...
