The Research On Operation Modes Of Cophase Continuous Traction Power Supply System

with the development of electrified railway,the cophase continuous traction power supply system is different from the traditional traction power supply system,all traction substation realize electrical connection in the cophase continuous traction power supply system,a traction load power is provided by the adjacent multiple traction substation at the same time,the cophase continuous traction power supply system greatly enhance its capability of power supply,if it can match with traffic organization and external system more optimally,so optimal matching is more able to embody its advantage.During the process of operation and maintenance,he treatment measures of the traditional traction power supply system have been formed system in China.It is of great significance to how to run stably in power supply system and establish the relationship between the power supply system and the cophase continuous traction power supply system.Firstly,the main work of this article is to built the cophase continuous traction power supply system by the matlab,based on the AC electrified railway traction power supply system and train operation simulation platform.It will analyze influence of power supply equipment capacity setting by simulation for different types of electrification railway train operation organization in the cophase continuous traction power supply system.In the fault conditions of the cophase continuous traction power supply system,how to arrange the traffic organization is the part of this article.Traction load dynamic simulation realize these functions.Then,according to the present situation of the traction power supply system and power system,established the model of cophase continuous traction power supply system,simulated and analysed the influence through the cophase continuous traction power supply system after short-circuit fault in power system;finally,established matching relationship of the power system and cophase continuous traction power supply system.
