Abstract

AbstractIn the initial construction and scientific research activities of urban rail transit, there are high requirements for the management analysis and use of train line operation data, line parameters, electrical parameters, and simulation evaluation of design schemes. Therefore, the establishment of a physical simulation system for urban rail transit is an important research direction. The full physical simulation of the entire rail transit line can simulate the operating status of the real rail train as much as possible, and collect various line parameters and electrical parameters during train operation. And analyze it accordingly. Compared with the difficulty of collecting large amounts of data on real rail transit lines, the urban rail transit traction power supply dynamic simulation platform introduced in this article can simultaneously conduct eight traction stations. The various operating data of the two main institutes are collected and processed in real time. The dynamic simulation platform focuses on establishing the physical model of the low-power rail transit traction power supply system to simulate various operating conditions and fault states of the actual traction power supply system, and provide a large amount of valuable data for the actual rail transit line construction.KeywordsTraction power supply systemSimulation platformPI control
