Scheme for Substation Electrical Energy Acquisition and Communication
Release date:
2026-05-20
For the substation electrical energy data acquisition and communication system, the solution ensures stable operation and high levels of data integrity, online availability, timeliness, and accuracy. It effectively addresses recurring issues such as faults, line disconnections, and packet loss, thereby guaranteeing reliable and accurate data transmission through the acquisition terminals’ communication channels.
To achieve the aforementioned objectives, the substation energy‑metering communication scheme must adopt an advanced and reliable technical architecture. On the one hand, a high‑speed, stable dedicated communication network—such as fiber‑optic communication—can be employed, offering significant advantages including high bandwidth, low signal loss, and strong anti‑interference capabilities. This effectively reduces packet loss during data transmission, ensuring that data is conveyed accurately and completely from the collection terminals to the master station system. On the other hand, intelligent communication management devices should be introduced; these devices can monitor the status of communication links in real time and, upon detecting a disconnection or fault, promptly and automatically switch to a backup link, thereby guaranteeing uninterrupted communication. Meanwhile, by optimizing communication protocols, the timeliness of data transmission can be enhanced, ensuring that energy‑metering data is uploaded accurately within the prescribed timeframe. In addition, a comprehensive fault‑early‑warning and diagnostic mechanism should be established. Leveraging big‑data analytics and artificial intelligence, operational data from communication equipment can be deeply analyzed to proactively identify potential fault risks and address them promptly, thus comprehensively improving the stable operation of the substation’s energy‑metering communication system and meeting the power industry’s stringent requirements for high‑quality data acquisition and transmission.
The solution enables unified monitoring and management of both central-office and remote‑end equipment; supports ring‑network protection and linear 1+1 protection; and allows the network management system to perform centralized operations across complex, multi‑device networks. It also features adaptive service interfaces and interoperability with equipment from other vendors, among other well‑designed configurations. Furthermore, the equipment offers seamless, non‑disruptive software updates and robust service‑expansion capabilities, ensuring readiness for future growth.

Features of this plan:
Network management enables centralized operation, maintenance, and management (OAM) of complex networks composed of multiple devices, facilitating circuit configuration and scheduling while ensuring secure and reliable network operation.
Supports unified monitoring and management of both central-office and remote devices; incorporates built-in DCN capabilities to enable centralized network management; and provides DCN protection features to achieve self-healing of the DCN.
It supports standard encapsulation protocols (GFP) and mapping protocols (virtual concatenation/LCAS), enabling interoperability with MSTP equipment from different vendors.
Supports EOPDH Ethernet access and GFP encapsulation, with the ability to dynamically adjust bandwidth.
Supports mixed‑card insertion (including SDH optical interface cards, E1 interface cards, multi‑service aggregation cards, etc.) and hot swapping.
Supports online replacement of the primary controller without service interruption or changes to configuration information, and can automatically retrieve configurations from the business module.
Supports standard clock functionality.
It offers excellent compatibility and scalability: when new‑type or new‑version line cards are introduced, existing system applications or software upgrades do not disrupt ongoing services.
