Abstract: To address the constraints of power communication systems in terms of stability, real-time performance, and intelligent control, this study proposes a hierarchical decoupled communication network optimization design scheme. Practical application verification was conducted on a typical distribution network in Nanjing. Field operation results demonstrate that the average response delay for control commands is maintained below 92 ms. Under high-frequency telemetry traffic conditions, the overall communication latency averages19.2 ms with a peak not exceeding 36.5 ms. The dispatch module reliably supports issuing 220 control tasks per second, while the MQTT message queue packet loss rate remains below 0.02%. Under link failure and node disconnection scenarios, the system completed routing reconstruction or redundant takeover within 3 seconds, while the database’s dual-machine hot standby mechanism ensured data consistency. Research findings confirm the solution’s robust stability and engineering adaptability in multi-protocol integration, path optimization, real-time control scheduling, and anomaly recovery, providing technical support for regional deployment and expanded applications of power communication networks.
