Protection Schemes for Uniline Zone in Bilateral AT Traction Power Supply System

Abstract

With the rapid development of the construction of high-speed railway in china, higher levels of power quality and reliability of traction power supply systems are required. The combination of bilateral power supply technology with AT traction power supply technology can better meet the needs of development of high-speed railways, which will require new protection approaches to be proposed. Thus, corresponding protection schemes will be of great significance for the application and promotion of bilateral power supply technology.
