Development Of On-line Monitoring And Alarm System Of Protect Plate In Substation

With the development of the power grid,the substation equipment protection device is becoming more.The operations for protection of patrol are more frequent.To ensure the stable operation of power grids,operators need to spend a lot of manpower and material resources to the secondary equipment periodically patrol,the protection linking piece one by one check it.Hundred in a 220 kV substation protection screen,most of the protective screen and there are dozens of pieces of protection linking piece.The protection linking piece is checked one by one,and it will cause substation operation staff to work hard.In front of the huge workload is extremely prone to individual equipment malfunction.The clamp is error back without timely detection,and it will cause a significant power accident.According to the above situation,an innovation system is introduced in this paper,to solve the current problem of protect plate.Have linking piece state recognition function,this system not only can be realized through the network to tour d center under the jurisdiction of platen of substation remote monitoring,and once the plate there is an error,it will realize the alarm function.Based on the current traditional ways of checking the substation protection linking piece,a novel on-line monitoring and alarm system of protect plate in Substation is introduced in this paper.New research and development from the aspects of time and efficiency of the platen,comparing the on-line monitoring and alarm device to be more sure clamp the advantages of online monitoring and alarm device.And respectively from information conversion module,main control module,communication module,display module introduces system composition and implementation method.The performance characteristics of the system are analyzed,summarized the system commissioning during the year,we will further improve the improvement measures are put forward on the system.Last on-line monitoring and alarm device clamp system is introduced in this paper the popularization and application of,through to the system research and development,improve the degree of automation of relay protection operation management and the correctness of the protection device operation.
