A Container-Based Device Management Platform for Large-Scale Power Grid IoT Maintenance

Abstract

Large-scale power grid IoT deployments involve frequent firmware updates and configuration adjustments across geographically distributed terminals. Manual maintenance has proven costly and error-prone. A container-based device management platform was deployed in a provincial power monitoring network covering 2,436 terminals and 178 gateway nodes. The system operated continuously for nine months, supporting remote configuration, incremental upgrades, and failure rollback. Operational logs indicate that average update completion time decreased from 47 minutes to 19 minutes per batch. Large-scale rollback events were reduced from 6.2% to 1.4%, while on-site maintenance visits declined by approximately 38%. Network congestion during peak update periods remained below 62% utilization. These results demonstrate that containerized management can significantly improve reliability in large-scale grid environments.
