Relay protection service support platform architecture and data flow based on big data technology

To achieve "source maintenance, global sharing" of relay protection operation data, improve professional analysis capabilities of relay protection, establish a relay protection equipment label to realize multi-angle and all-round portraits of relay protection equipment, construct an integrated data model of protection operation information based on big data technology, propose the overall modeling principles and the overall architecture of the model. Based on an integrated data model, propose the overall architecture of the relay protection service support platform, the platform is divided into a big data service layer and a logical layer. The big data service layer completes data collection, storage, management, and integration, the logical layer implements 9 categories of applications for protection of life cycle information management, equipment evaluation, fault and motion analysis, intelligent diagnosis, intelligent warning, defect management, maintenance and anti-accident measures, refined management, and intelligent assistance. A data flow architecture based on the service support platform for ledger, defect, maintenance, action, and alarm is proposed.
