Basic design consideration of CFETR fusion power stations

The China fusion engineering test reactor (CFETR) is an ITER-like tokamak system for fusion energy development. The goals of CFETR are intended to realize tritium self-sufficiency and utilize 200MW output fusion power to product electrical energy. Its ITER-like HV substation receives power from the 500 kV transmission grid for powering its pulsed power electric network and steady-state electric power network. This paper describes the concept design of the electric power system, with emphasis on its turbine generator and high accuracy exciting & protection system. It analyzes different strategies of putting the generator power to the grid.
