The auxiliary control system of power plant is mainly divided into conveying system, ash removal/slag removal system, ash blowing/fixed discharge system, dust removal system, desulphurization system and so on. The system is characterized by large information flow, high demand for real-time information, high demand for reliability of network equipment and availability of network system.

The Gigabit management series products independently developed by our company realize multi-system mutual communication in the centralized control system of a power plant auxiliary system. In this network topology, the central control room uses NEU50244T8CGS-SFP core layer Industrial Ethernet switch as the backbone network link dosing workshop, grey control workshop, Circulating Pump Room, integrated pump room, NEU3082GM-SFP Industrial Ethernet switches for sootblowing and other systems. The backbone switches use a gigabit fiber link redundant self-healing ring network for data exchange, increasing the bandwidth for data exchange and supporting network switching with large data volumes, the topology can realize automatic handoff when the link is down ＜50ms, so that the communication cannot be affected.
