Exploration of Data Penetration and Retrieval Technology for the New Generation Equipment Centralized Monitoring System

In order to meet the business requirements of the new generation of centralized equipment monitoring system for dynamic reading of substation data, the SCD model is cut out with the idea of hierarchy and domain through unified model service, and the cut SCD model is converted into CIM/E format for storage with the granularity of bay layer, device layer, and measurement domain, so as to retain all model information of the substation. The retrieval application can quickly access the model data through the unified model service. The retrieval application can complete the creation, subscription, request and other operations of the dynamic data set based on DL/T 860 services through the front-end dynamic data set service agent and related supporting modules, and quickly realize the temporary collection of data. At the same time, the automatic mapping technology is used to dynamically generate a graphic image showing the substation data, so as to support fault analysis and other scenarios, Dynamically expanding the model to monitor the business requirements of the entire substation signal.
