Abstract:

The design and implement of logical control and monitor system of the lower hybrid current drive (LHCD) system on HL-2A tokamak was present. The system was based on the SIEMENS S7-400 series PLC. The performance on anti-interference was increased by using the industrial ethernet network, optical fiber isolation, embedded controller technology. The interlocks, parameter setting and remote monitor were established. The lower hybrid wave was injected into HL-2A plasma with the logical control system. It shows the logical control system was successfully developed.

Key words: LHCD, Interlock, PLC, Optic isolation;

摘要:

介绍了以西门子S7-400系列PLC为核心的HL-2A装置2MW/3.7GHz低杂波电流驱动的逻辑控制系统的设计与实现。采用了工业以太网通讯技术、光纤隔离技术、嵌入式控制技术、串行通信技术及模块化控制技术等,提高了系统抗干扰性能及可扩展性,实现了低杂波系统逻辑互锁、参数设置和远程监控等功能。实验证明系统在装置放电的复杂电磁环境下,运行稳定、功能完善。
