Research And Development On Maintenance Management System For Protection And Relay Devices Of Jilin Grid

Relay is an important guarantee for the security and stability operation. How to make protection overhaul more scientific, more systematic and efficient power supply enterprises is an important issue. Meanwhile, in the relay maintenance manpower, material costs and increasing system power outages, equipment outage fewer opportunities under the dual pressures of the drawbacks of the traditional planned maintenance mode gradually. Therefore, to carry out protection equipment condition-based maintenance, condition-based maintenance management system to develop protection, reliability has important practical significance to improve the relevance and effectiveness of the repair of protection, reduce labor and material costs, improve security of supply and.First, this article describes the protection status of maintenance management systems background and significance of research and development, process development and application status and condition-based maintenance management system conducted in-depth research. Secondly, the Jilin Power Grid relay condition-based maintenance management, basic data and information gathering, the state evaluation methods, condition-based maintenance methods, and according to the actual situation and development prospects of the grid overhaul of Jilin Power Grid relay state maintenance management out of necessity and practical feasibility of the system of research and development conducted in-depth elaboration. Again proposed application IEC61970 standard CIM model modeling protection equipment, building protection equipment status evaluation model of digital state maintenance management system design, a clear development direction of system management, design principles, structure and hardware configuration, deployment and configuration, so as to establish a set of scientific, systematic, advanced, operability in one of the relay state maintenance management system. Finally, it describes the function relay condition-based maintenance management system implementation, verification of the system is to improve protection for maintenance efficiency and reduce maintenance test costs and enhance the important role of supply security and reliability aspects and practical significance.
