The signing of a Procurement Arrangement not only marks a big milestone for the project, it is also a welcome break in the very busy ITER agenda. This week, the champagne glasses were raised on the occasion of the successful accomplishment of Procurement Arrangement 4.1.P2.CN.01 and 4.1.P2.CN.02 which symbolize the legal and technical framework for ITER's AC/DC converters and reactive power compensator & harmonic filtering.
The Chinese Domestic Agency will procure all fourteen poloidal field converters that will provide controllable current/voltage to ITER's six poloidal field coils. The procurement package includes the design, fabrication, delivery, installation, assembly, integration and site acceptance test of the converter units. It is a very challenging system due to unprecedented power level and short circuit current, and the high dynamic demanding from the need of the plasma control.
The Chinese Domestic Agency will also procure the ITER's reactive power compensator and harmonic filtering system rated at 750Mvar to stabilize the power grid and to provide required quality of the electrical power to operate ITER. It is a unique system due to the installed power, the extreme high demands on the response time and the expected loads.
