Design of The Power Supply and Distribution Monitoring System for NNBI

The power supply and distribution system provides powerful support for the efficient operation of the negative ion source neutral beam injector (NNBI) experiment. To centrally manage the power supply equipment of each subsystem of NNBI, a power supply, and distribution monitoring system based on WinCC software and SQL Server database is developed. The system has an excellent man-machine interaction interface and realizes the monitoring and management of energy consumption in the power supply and distribution system. It has circuit process monitoring, fault alarm, operation log, historical data query, and other functions. After testing, the system can run stably and reliably control each device. At the same time, the system has good compatibility and expansibility and meets the needs of intelligent management and monitoring of the power supply and distribution system.
