Evaluation Of Intelligent Substation Network And Two Equipment State

In the secondary device self-test capability maturing new situation, periodicinspection system using conventional equipment maintenance started to becomeobsolete by the preventive maintenance plan to overhaul the state transitionpredictability has become the development direction. This paper describes theintelligent substation secondary system presents new features and drawbacks of thetraditional repair methods. Actuality overhaul Jiangxi intelligent substationprotection equipment, a detailed analysis of the current outstanding problems inmaintenance policy exists and secondary main factors affecting the normaloperation of equipment。Construct a reasonable device status evaluation model to accurately grasp theoperating conditions for the equipment and the development trends and developstrategies targeted maintenance provided strong support. In this paper, acomprehensive evaluation of health status of the secondary device based on fuzzymathematics, according to the theory of fuzzy mathematics degree of membership ofthe qualitative evaluation into quantitative evaluation of the operating performance ofa comprehensive assessment of protection equipment for equipment operation,maintenance and repair offer basis。Based on the construction of a single device failure risk model, combined withthe actual running of intelligent substation, in-depth evaluation of the work carriedout on the business loop and overall functionality of intelligent substation failurerisks, in order to more complete and comprehensive assessment of intelligencesubstation risk。...
