摘要
介绍了以Siemens S7-300PLC为控制核心的HL-2A装置电子回旋共振加热控制与保护系统的设计与实现。系统采用了基于工业以太网的分布式结构,使用VFC/FVC电路和光纤隔离技术传输高电压/大电流的测量与控制信号,确保了控制系统运行的电气安全性,增强了信号传输过程中的抗干扰能力;加热系统的保护采用基于CPLD/FPGA实现的快速保护技术。实验证明该控制与保护系统具有兼容装置现场强电磁干扰的能力,运行稳定可靠、功能完善并具有良好的扩充性能。
The design and implementation of the control and protection system which was build up around the SIEMENS S7-300 PLC in the ECRH system on the HL-2A tokamak is introduced.The system uses the distributed architecture based on industrial Ethernet.And the system also uses fiber isolation technology to transmit high voltage/high current measurement and control signals in order to ensure the security and the stability of the system,while enhancing the anti-jamming capability of the signals during the transmission process.The heating protection system adopted the fast protection technology based on CPLD/FPGA.It has proved that the control and protection system is stable,reliable and compatible with the strong electromagnetic interference on the HL-2A.The whole system is also fully functional and has a good scalable performance.
