PURPOSE: A time synchronization system for an operation of a superconducting tokamak is provided to obtain a stable driving operation by sequentially and organically operating a superconducting magnet power supply unit, a heating unit, a diagnosis unit, and a plasma control unit. CONSTITUTION: A GPS receiver(100) receives a world standard time from a GPS satellite and provides the word standard time. A central timing unit(200) generates and provides reference time information and a tokamak driving synchronization signal. A plurality of local timing units(300) provide synchronization signals for each unit of a superconducting tokamak device including a plasma control system, a superconducting coil power supply unit, a fuel injection system, a heating unit, and a diagnosis unit. A switch board(400) distributes synchronous signals to the local timing boards. An exclusive network(500) connects the central timing unit and the local timing unit to the exclusive protocol.
