Research on a New Technology of the Condition Monitoring of Intelligent equipments in Intelligent Substations

Abstract:
Focusing on the core concept of "regulation and control integrated with operation and maintenance" and expanding intelligent application, the overall design scheme of the online monitoring system for the secondary equipment of the intelligent substation is proposed in this paper based on the digital design of finished products, realizing the functions, such as status perception and safety detection of smart substation secondary system, status assessment technology, fault diagnosis technology and intelligent security measures. At the same, it provides multi-dimensional visual information support and decision-making and safe operation basis for the daily operation and maintenance, exception handling, accident analysis, and maintenance of the secondary system in the smart substation.
