Methodology for the deployment of ITER Fast Plant Interlock system. Use case: ITER Poloidal Field and Central Solenoid coil's power converter protection system

This work describes in detail this methodology, valid for most cases just selecting different input/output signal types to be handled and choosing different numbers of interlock functions to be performed. In addition, this paper describes the development of the interlock system for the ITER Poloidal Field and Central Solenoid Coil's Power Converter protection, a special case due to its unique configuration, the most complex implemented up to date. The development of this special case “puts to a test” the methodology's approach. Finally, the discussion of the fitness of the methodology and the performance of the system is presented.
