ITER ECH&CD Control System: Architecture, interfaces and status of development

The ITER ECH&CD system is designed to inject 20 MW of millimetre-wave at 170 GHz into the vacuum vessel. composed many sub-systems, namely High-Voltage Power Supplies (HVPS), Gyrotrons, Transmission Lines (TL), Ex-vessel Waveguides (EW), Launchers. It role EC Plant Controller (ECPC) integrate all Sub-system Control Units (SCU), prepare for operation and execute real-time requests coming from plasma control system. ECPC also implements plant level protection functions involving more than one sub-system it interfaces with Central I&C. This paper gives an overview a description development focusing on architecture interfaces. are presented together functional allocation better define responsibilities. preliminary design interface Plasma System implement advanced presented.
