抜粋

Tokamak devices with non-superconducting coils must be equipped with pulsed power supplies employing energy storage system when the devices cannot receive electricity from power grids directly. Flywheel energy storage system (FESS) for the coil power supplies have been used only in large or middle-sized tokamak devices since they employed synchronous motor generators (SMGs), which have difficulty in downsizing and maintenance. In our previous research, FESS with induction motor generators (IMGs) utilizing self-excited phenomena was developed. In this paper, using two novel concepts of multiple IMGs and installing a multistage converter, both of design flexibility and coil current ripple reductions are realized. As an experimental result, a peak load power of 778 kW and an electric energy supply of 408 kJ to the dummy coil were achieved using a toroidal field coil power supply (TFCPS) of a tokamak device, PLATO.
