HL-2M 装置运行控制技术初步研究

重点介绍了 HL-2M 装置的运行技术和初步的等离子体控制实验结果，包括等离子体放电方案设计、 线圈电流控制、击穿阶段零场匹配和等离子体电流以及位移的控制。为了降低放电运行风险，HL-2M 装置初始放 电采用了简化的放电方案，通过整定 PID 参数实现了线圈电流控制，在击穿阶段获得了 10V 以上的环电压和较大 范围的零场区域，成功实现等离子体击穿。最后，投入了等离子体电流和水平位移反馈控制算法，成功将等离子 体放电脉宽提升至 200ms 以上，且维持 I_p≥100kA 的时间超过了 100ms，上述结果表明 HL-2M 装置运行控制技术 得到了初步的检验。 

Preliminary research of HL-2M tokamak operation and control techniques

This article mainly focused on HL-2M tokamak operation and preliminary plasma control  experimental results, including plasma discharge scenario design, coil current control，null field test and  calculation, plasma current and position control. A simplified plasma discharge scenario was adopted to reduce the  risks of first plasma operation. The coil current control was successfully implemented by setting the PID  parameters. The first plasma breakdown was successfully achieved by performing a breakdown loop voltage  higher than 10V and a large area of good null field. Finally, a dedicated plasma control scheme on plasma current  and radial position are designed and implemented, the plasma duration was increased to more than 200ms,and the  time to maintain I_p≥100kA exceeds 100ms.The above results demonstrate that HL-2M tokamak operation and  plasma control technology has been preliminarily tested by experiments.
