Research And Practice Of Traction Substation Integrated Automation Retrofit

In recent years,microelectronics technology,computer technology and communication technology rapid development,electric traction substation,partition and open and close a lot with the remote communication,remote sensing,remote control,remote regulating four control function of the integrated automation system.Traction substation,partition and open closed mostly located in remote areas,with automatic monitoring,automatic measurement,automatic control and protection functions as one of the integrated automation system,in the distance can be achieved by integrated automation circuit breaker and isolating switch for remote control and protection functions for area code switching,protection setting,a failure occurs,can as soon as possible through the distance resection fault power operation,for the traction substation,partition and open and close the security and stability of none or little humanization management to lay a solid foundation,improve the quality of the field device operation,improved the working environment and living conditions of the personnel on duty.This article first to narrative of integrated automation system development situation at home and abroad,combined with the present situation of traction substation,renovation project actual situation,the investment benefit,the microcomputer protection modification model compared to conventional substation,and the characteristics of the digital integrated automation transformation,finally decided to adopt technical transformation of mature hierarchical and distributed model updating traction substation integrated automation system.For the selected mode transformation of the main technical points of the integrated automation protection device equipped with detailed instructions,and the function of upgrading scheme,contingency plans and construction steps of the specific studies,the integrated automation system protection setting value calculation and protection function test was carried out in detail,and then in view of the technical problems encountered in the process of transformation of careful analysis,for the new and old traction substation integrated automation equipment upgrading construction provide field experience and technical support.
