Railway Power Lines Application Of Automation Technology Research

Track line long, terrain complex, rail line supplied power for the electrical power system maintenance management to bring the very major difficulty, once appeared the breakdown, had to spend the massive manpower physical resource, also restored the time which the power supply needed very to be also long, adapted the modern railway transportation request with difficulty 。 Along with the national economy fast health development, increasingly is also high to the railway transportation request。 Safe, on time, fast, is comfortable is the railway transportation goal。 Must achieve this goal, provides the reliable electric power safeguard, establishes the railroad electric power far to move the system to have the count for much significance。This article unifies the cubic centimeter which the our company is responsible to construct from XIAN to Hefei the line electric power far to move the project, in this project the application electric power far moves the technique---- railroad line automation, and practiced two aspects from the theory to conduct the thorough research, has confirmed this technical feasibility and the usability, and on this technology the question which appeared in the application process, proposed solution。The paper has carried on the analysis to the line automation technology。 First briefed the line power supply sector running status, the power supply direction monitor(Is effective and the invalid condition including the power supply direction, the gain power supply side sucks), the system constitution and between the system various equipment correspondence plan 。 Then emphatically analyzed and has discussed the line fault automatic detection and the localization 。 Is in from the line when Phase fault breakdown, the single-phase earth fault, high breaks by pressing the breakdown three kind of malfunctions, aspect and so on line fault monitor and localization has carried on the detailed elaboration。 Complete line automation treating processes including the breakdown monitor and the localization, the failure isolation, restore supply power three steps。 This article while detailed introduction breakdown automatic detection and localization, when to line Phase fault and high pressure disconnection fault two kind of breakdowns types the line failure isolation and the breakdown automatic reduction have made the detailed discussion 。After the detailed theoretical analysis and the overall system successful association accent indicated far moved the technology to gather in the track line application in the west to obtain the success. This technology is broad in the railroad power supply system prospects for development, has the good social efficiency and the economic efficiency。...
