Technical Analysis of Grid Connection of High-speed Railway Power Through Lines

Abstract

For the power communication system of the high-speed railway, the power through line is the core power supply line, and its operation effect has a vital effect on the safety and stability of the high-speed railway operation. However, because the power penetrating line is largely restricted by the power system, and the lightning protection measures and insulation level are relatively weak, the grid connection is also very difficult. In order to realize the effective grid connection of high-speed railway power through-line, this paper analyzes its grid connection technology. In this analysis, it first analyzes the overall overview of the high-speed rail power penetration system; then it analyzes the specific principles of grid connection of the high-speed rail power penetration line; Finally, the simulation calculation and analysis of the specific grid connection are carried out. It is hoped that this analysis can provide sufficient technical support for the grid connection of the high-speed rail power through-line, so as to improve its application effect and safety.
