A power rail power supply system and power supply control method thereof

Abstract

The invention provides a power rail power supply system and a power supply control method thereof. The power rail power supply system includes a traction control system, an operation control center, a DC incoming cabinet, a feeder cabinet, and a power rail section, and also includes a controller connected to the traction control system and the operation control center, which is used to generate power The distribution plan of the rail section and the opening and closing instructions of the switch in the feeder cabinet; the ground sensor that can communicate with the above-mentioned controller is provided on the power rail section. The present invention adopts the intelligent controller technology to obtain information such as the position and speed of the vehicle in real time, combined with the operation and control rules, it can assign the power rail section to the vehicle to be charged before it enters the power rail, and at the same time, according to the ground sensor detected Passage information of vehicles on the power rail, real-time switching of the power-on state of the power rail section, realizing power-on when there is a car, and no power-on when there is no car.

Description

technical field [0001] The invention relates to the technical field of vehicle power supply, in particular to an intelligent power rail power supply system suitable for maglev transportation and a power supply control method thereof. Background technique [0002] The power rail is the power supply equipment that provides electric energy to the maglev vehicle. When the speed of the vehicle is lower than the set speed threshold and the on-board motor is not enough to provide electricity for the vehicle, the vehicle’s collector shoes will fall down and contact the power rail, which is provided by the power rail. Electricity demand in the vehicle. [0003] Traditional power rail power supply systems such as figure 1 As shown, its working principle is as follows: the traction control system sends the opening and closing command of the switch to the PLC controller of the DC incoming cabinet, and the PLC controller converts the above command into a digital signal to control the op...

AI Technical Summary

Problems solved by technology

[0004] At present, in the field of maglev transportation, considering the cost and the convenience of operation and management, the power rail will always be powered on during the operation stage, and will not be powered off until the end of the operation, and the power supply state cannot be switched in real time according to the traffic conditions of vehicles.

When the power rail is charged for a long time when there is no traffic, it will cause no-load loss and increase the risk of electric shock
