The aim of the numerical modelling is to study different regimes of operation of the TEXTOR 94 poloidal magnetic field system. The model allows to take into account the gaps between the parts of joke, nonlinear magnetic characteristics of ferromagnetic, discharge parameters as well as to simulate the operation regime providing scenarios for discharges with equilibrium conditions. The model includes vacuum vessel and liner and makes it possible to study the start up phase. Inductance matrix and efficiencies of the poloidal coils are determined for different levels of the iron magnetization. The results of the coils magnetic field measurements have been compared with the calculated ones. The ways of the stray fields compensation in this region for the start up phase have been proposed. On the basis of the predefined currents in the poloidal field system the possibility is shown to calculate the plasma parameters (current, inner inductance, elongation). The calculated parameters are in a good agreement with the experimental ones. The TEXTOR 94 magnet system incorporates 16 toroidal field coils (TFC). The coil system forms a vault inside to support centripetal forces. At the outside the coils are connected via intercoil structures taking the tilting moments. 2D and 3D finite element stress analyses of the TFC under electromagnetic and thermal loading have been performed for the upgrade system parameters. Contact interaction between the magnet system components has been taken into account. |
