Stability Analysis of Power Transfer in PF Supply System of Compass-U Tokamak.

Abstract

Power transfer stability in supply circuits of PF (Poloidal Field) coils has been analysed. Proper energizing of these coils is necessary for COMPASS-U tokamak experiments. The analysis main method is linearization of a non-linear system in a steady-state working point. The steady state-points have been specified by the Institute of Plasma Physics ASCR so that the whole operating area of the tokamak would be involved. At first, a simplified numerical model has been set up and analysed, then the analysis of a complex model of the PF supply system has been carried out in several versions according to the requirements of the contractor
