摘要

韩国超导托卡马克高级研究磁体(KSTAR)极向场磁体系统存储的能量非常大，猝灭检测系统(QDS)是保证磁体系统稳定运行的关键。为了快速响应，采用了基于电压的QDS。采用共绕式电压传感器和平衡桥电路消除等离子体运行过程中产生的感应电压。然而，由于脉冲电流工作时的感应电压比猝灭检测电压高出数百倍，因此提出并研究了中心差分平均(CDA)和MIK，其中I和K代表不同电路的相互耦合指标，这是一种相互产生电压的主动抵消。本文将CDA和MIK技术应用于KSTAR磁体的PF磁体淬火检测。通过比较MIK计算的感应电压和CDA电路测量的电压，消除了结果信号中的感应电压。

Study on quench detection of the KSTAR CS coil with CDA+MIK compensation of inductive voltages

Quench Detection System (QDS) is essential to guarantee the stable operation of the Korea Superconducting Tokamak Advanced Research (KSTAR) Poloidal Field (PF) magnet system because the stored energy in the magnet system is very large. For the fast response, voltage-based QDS has been used. Co-wound voltage sensors and balanced bridge circuits were applied to eliminate the inductive voltages generated during the plasma operation. However, as the inductive voltages are hundreds times higher than the quench detection voltage during the pulse-current operation, Central Difference Averaging (CDA) and MIK, where I and K stand for mutual coupling indexes of different circuits, which is an active cancellation of mutually generated voltages have been suggested and studied. In this paper, the CDA and MIK technique were applied to the KSTAR magnet for PF magnet quench detection. The calculated inductive voltages from the MIK and measured voltages from the CDA circuits were compared to eliminate the inductive voltages at result signals.
