Study Of Substation Secondary Equipment Remote Control Technology And Its Application

In recent years, with power grid equipment is increasing, the traditional maintenance mode and the present condition of the limited maintenance resources, gradually aging equipment and the increasingly prominent contradiction between high reliable power supply requirements. How to through effective means, refining equipment management, precontrol equipment status, management actively, from "passive emergency maintenance" to "active service", take the initiative to the local structure or parts in the original design of equipment for maintenance or modification, fundamentally eliminate the hidden trouble of equipment malfunction, eliminate failure or hidden trouble of equipment, is of great significance for improving power supply reliability and practical value.Along with the development of the secondary equipment technology and upgrading the quality of products, the device itself has a strong self-checking function, however, the secondary equipment management still stays in the "devices", upload signal mainly for the entire screen the whole device device "abnormal", "device alarms" coarse abnormal information, such as paper, combined with the secondary equipment remote control platform construction, refining equipment management discussion and research, and practice "active management". Paper main work includes:(1)In the second equipment intelligent diagnosis analysis done in-depth research, based on the equipment asset information and operation information of secondary equipment diagnosis analysis method, including the secondary equipment fault diagnosis based on decision tree and alarm processing method, based on the secondary loop state estimation of secondary equipment hidden fault active warning methods, statistical analysis of secondary equipment failure and implicit troubleshooting methods and secondary equipment fault diagnosis intelligent report generated;(2)In the secondary equipment management are studied, realizes the secondary equipment management, spare parts management, defect management, technical data management, and other functions, and realize the secondary equipment of real-time dynamic early warning function, statistics and analysis with graphical display related functions;(3)The fixed value of secondary equipment, switch check was studied, and realization of the entire network protection fixed value periodically summon, and automatically compare with standard setting the function of checking, and found the differences and issued a warning to users;(4)Through the information system of protection station to realize the function of remote control, the constant value operation (modified bottoms fixed value, switch fixed value area), cast out soft clamp, remote control functions such as remote reset operation technical solution is given;(5)The remote control platform architecture, we propose a secondary equipment associated modeling methods and devices of the plug-in modeling method.
