Research on BOP Centralized Monitoring Technology in Nuclear Power Plant
Aiming at the current situation of high operation cost brought by the decentralized monitoring mode adopted by each balance of plant(BOP)of nuclear power plant,a BOP centralized monitoring system of nuclear power plant based on field equipment layer,control layer,network communication layer and operation monitoring layer is designed to realize the centralized monitoring of each BOP.A BOP centralized control room is set up to improve the BOP automation control level and realize BOP unattended operation,which achieves the purpose of reducing staff and increasing efficiency.The network communication layer adopts the network topology of redundant monitoring ring network and redundant information ring network,physically separating the monitoring network that transmits real-time data from the information network that transmits non-periodic data,diverting the monitoring data from the information data,and improving the reliability of the network communication layer.The BOP centralized monitoring system adopts a unified control system platform,which reduces the types and quantities of spare parts for control system hardware and software as well as equipment management costs.By applying the computerized protocol system and alarm display system designed in the server,it reduces the work intensity of the operators and enhances the friendliness of human-computer interaction.
