We present the results of fast time scale plasma control simulations for the proposed Korea Superconducting Tokamak Advanced Research (KSTAR) tokamak. Here, the fast plasma control includes stabilization of the vertical instability and rapid radial position control. As a simulation tool, we use the tokamak simulation code (TSC). We evaluate the power supply requirements for both the vertical and radial position control with a similar approach to that which was employed in the analysis of the tokamak physics experiments (TPX). In particular, we investigate the efficacy of control coil locations to minimize the power supply requirements. From this study, it is shown that two separate sets of control coils, one responsible for vertical control and the other responsible for radial control, are required to provide robust control of both vertical and radial position for all the anticipated plasmas in KSTAR experiments. |
