Division Spotlight
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

The ITER poloidal field (PF) coil power supply system consists of 14 basic converter units that feed six superconducting coils. The converter unit is the complicated, challenging, and unique system to realize four-quadrant operation compatible with the superconductive load and the demand for plasma control. This paper describes the final design of the control strategies, which are implemented in the local controller of the PF converter system. They are zero crossing current control strategy in circulating operation mode, current balance control strategy in parallel operation mode, and hysteresis band control strategy in mode transition. In addition, the performance of the control system is demonstrated by the analysis, and the control strategies are validated by the simulations and corresponding tests.
