Abstract

With the development of railway transportation, traditional electric power

networks and power dispatching models in railway can not satisfy the demands of

railway transport development. The remote supervisory control technology has been

applied in railway power supply and traction power supply based on information

technologies such as computer technology, communication technology and automation

control technology. The remote supervisory control system for railway not only can

improve greatly the degree of automation in the railway power dispatching system for

railway, but also can guarantee effectively the supplies of railway stations and relay

stations for section signals. The key problem that whether could maintain its stability

depends on the remote terminal units running properly. However, the remote terminal

units in railway electric power have seldom been studied. For this purpose, the

following research work has been completed:

Firstly. Under the current situation of speeding up the implementation of high

speed railway construction, it has been pointed out that the remote terminal unit is a

profound and special part of the remote supervisory control system for railway based

on the current situation of railway electric power supply, and these equipments in the

remote supervisory control system for railway have some defects during the setting-up

and operating;

Secondly. The compositions and operating principles in the remote supervisory

control system for railway are analyzed in detail and basic functions,working

conditions and parameters in the remote terminal system are designed;
