Simulation studies of the protection system for the superconducting coils of Helias Stellarator Fusion Reactor

The Helias Reactor (HSR) is the study of a stellarator fusion reactor configuration. The goal of this fusion power plant is to deliver electric power to the grid. One of the main technical components of the Helias Reactor is the superconducting coil system. A safety system, inserted between each power supply unit and the coil group, protects the superconducting coils in case of faults. The proposal deals with the computer simulations of the protection system of the Helias Reactor, using the SIMPLORER code. The computation of induced eddy currents in the structure during transient processes was transformed into electric network analysis by means of the finite element network (FEN) method. This approximation allows the investigation of the whole system including power supply and passive structures.
