The Supervisory Control System for the HL-2A Neutral Beam Injector

摘要

Supervisory control and protection system of the neutral beam injector(NBI)inthe HL-2A tokamak is presented.The system is used for a safe coordination of all the main NBIsubsystems.Because the system is based on computer networks with its transmission medium ofoptical fiber,its advantages in high operational stability,reliability,security and flexible functionalexpandability are clearly shown during the NBI commissioning and heating experiment in HL-2A.
