Application of magnetic field power supply in HL-2M tokamak first plasma discharge

磁场电源是HL-2M装置初始等离子体放电的重要组成部分,它关系到HL-2M装置零场的建立,等离子体的击穿和维持及位形控制。为实现初始等离子体放电所需的供电电压和电流,对磁场电源从主回路、控制、测量和保护分别作了相应的调整。在此基础上进行了大量的工程调试,确保了磁场电源的控制和保护等性能达到初始等离子体放电的需求。在磁场电源运行中,电源控制性能和输出参数的一致性、纹波质量等都有显著提高。介绍了磁场电源在调试及HL-2M装置初始放电中的应用。

Magnetic field power supply is an important part of first plasma discharge in HL-2 M tokamak,which is tightly related to the establishment of zero field, plasma breakdown and maintenance as well as configuration control. In order to obtain the voltage and current of the power supply required by the first plasma discharge, the main circuit, control, measurement and protection of the magnetic field power supply are adjusted,respectively. On this basis, a variety of engineering debugging is carried out to ensure that the control and protection performance of the magnetic field power supply can meet the requirements of the first plasma discharge. During the operation of the magnetic field power supply, the consistency and ripple of the control performance and output parameter of the power supply are significantly improved. In this paper, the applications of the magnetic field power supply in the debugging and HL-2 M first plasma discharge are introduced.
