摘　　要：EAST作为第一个纵场和极向场磁体都是全超导的装置,如果其超导磁体失超,其储存在磁体内的巨大能量将会转变成热能并造成磁体损坏,因此,可靠的失超检测是装置稳态运行的关键.EAST失超检测主要采用同绕线和二次补偿相结合的失超检测方法,整个失超检测系统分为六个分系统.为了确保整个失超检测系统工作正常,必须提前检查各分系统工作性能.数值模拟仿真系统就是通过实际实验数据与数值模型作为输出信号对各分系统进行性能测试.本文主要介绍了本系统的设计方案和相关结构,并给出相关实验结果分析.EAST is the first fully Tokamak device whose toroidal and poloidal magnet are superconducting. The enormous magnetic field energy stored in the magnet system will transfer into thermal energy and cause the damage of superconducting magnet, if a quench happened. Therefore, reliable quench detection is a key issue for steady- state operation. The co-wound voltage tap sensor and the second compensation components are installed in the EAST Tokamaks as a basic quench detection method. The whole quench detection system include six sub-systems. In order to ensure the whole quench detection system work reliability, each component should make the assessment of its ability in advance. The objective of Simulation test system is to make a qualification test for each component through actual experiment data ＆ numerical model signal generation as an input. The paper introduce the design scheme and related structure for the system which met experiment ＆ technical requirements.
