Research and application of data on demand penetration retrieval based on DL/T860CMS standard

To address the continuous growth of equipment scale and the number of measurement points in autonomous and controllable intelligent substations, while existing data collection strategies, equipment modeling methods, and data transmission dimensions cannot meet the requirements of panoramic monitoring and deep data mining analysis for the new-generation of substation centralized monitoring system, this paper proposes a data penetration and retrieval method based on DL/T860 CMS standard. This article introduces the background and technical advantages of the DL/T860 CMS standard, as well as the overall process of on-demand access. It also designs the overall architecture, and discusses in detail the key technologies involved in file access, dynamic dataset access, and remote process access. The application results of on-site operation of multiple centralized control systems in Jiangsu, Shandong, Anhui, and other provinces show that on-demand penetration and retrieval services provide reliable technical support for centralized monitoring of substations, effectively improving the monitoring level of the centralized control system regarding the primary and auxiliary equipment of the substation.
