A Train Positioning Technology Based on Dual-Terminal Electrical Quantities

Xu, Zhenxing / Zhang, Gang / Han, Lun / Tan, Chen

Train positioning failure will directly affect the safe operation of the train. In order to ensure the accuracy and availability of train positioning information, a new positioning method is urgently needed as an important supplement to traditional positioning technology. The structure, parameters, and operation characteristics of the DC traction power supply system for urban rail transit are analyzed. According to the relationship between the equivalent model of the power supply network and train position, a new train positioning method based on the electrical quantities of two traction stations is proposed, and the least square method is adopted to solve the equations. In view of the possibility that two trains operate in a single power supply interval, a dual train operation positioning method is proposed by adding the electrical quantities of the two trains. The proposed methods are verified by experiments on the simulation platform of urban rail transit power supply system, which proves the feasibility of this method.
