Design of ITER Data Sharing System for PFCS

International Thermonuclear Experimental Reactor (ITER) is an international project to achieve controlled nuclear fusion. An essential plant system for this project is the power converter (PC) system of the poloidal field and central solenoid (PFCS), In order to realize the on-site I&C integration, the PF PC circuit controller (CCR) has to be developed. Therefore, the purpose of this article is to design such data sharing system, which can be integrated with PFCS PC MRC, as well as realize the complicated functional interfaces. In order to achieve the 1-kHz communication rate required by ITER, the integration interface uses the high-performance synchronous databus network (SDN) provided by the control, data access and communication (CODAC) system. Finally, the experimental results prove that the developed CCR communication system can satisfy the integration requirements and realize the system's long-time stable operation.
