AbstractEighteen Toroidal Field (TF) coils are operated on steady-state mode at highest current of 68 kA in comparison with the other pulse operation coils such as Poloidal Field and Central Solenoid coils in ITER superconductive magnet system, which are fed by Coil Power Supply Systema (CPSS). The reliability of TF circuit is significant to investment and nuclear safety of ITER machine. Hence, the comprehensive protection functions as Slow Discharge, Accelerated Discharge and Fast Discharge are required by ITER TF CPSS and the detailed realizations have been illustrated according to the different levels of faults to guarantee the safety of components including TF coils. In addition, the simulation model has been built by MATLAB/SIMULINK according to the real configuration of circuit and control system to verify the protection strategies and the satisfied simulation results have been obtained.

ITER环形磁场线圈供电系统的控制与保护策略设计

摘要 与由线圈电源系统供电的 ITER 超导磁体系统中的极向场和中央电磁线圈等其他脉冲操作线圈相比，18 个环形场 (TF) 线圈以 68 kA 的最高电流在稳态模式下工作。 (CPSS)。TF电路的可靠性对ITER机器的投资和核安全具有重要意义。因此，ITER TF CPSS要求具备慢放电、加速放电、快放电等综合保护功能，并根据故障的不同程度对其进行了详细的实现，以保证TF线圈等部件的安全。此外，
