Control of the Superconducting Magnet Power Supply for SECRAL

  • 摘要: 超导离子源(SECRAL) 的超导磁铁电源的控制非常重要。为防止超导磁铁的失超,需要对超导磁铁电源采用恰当的策略进行控制。在SECRAL 系统中,4 台电源分别为4 个超导线圈独立供电,供电的电流大小不同,电流上升和下降的速率也不同。4 个线圈的电流不平衡,将导致整个超导磁铁失超,所以超导线圈的电流上升和下降过程必须协同完成。为了提升磁铁电源的安全性和稳定性,设计并实现了一个远程控制系统。在硬件方面使用串口通讯服务器实现TCP/IP 网络通讯与RS232 串行通讯间的协议转换。软件使用VC++ 直接对串口编程完成。该系统能够自动完成4 台电源的同步操作,简化了超导离子源SECRAL的调试过程,提高了操作过程中的安全性。The control of the superconducting magnet power supply (SMPS) is very important for Superconducting Electron Cyclotron Resonance Ion source with Advanced design in Lanzhou(SECRAL). In order to improve the safety and the reliability of the SMPS, a remote control system was designed and implemented.There are four power supplies needed to be controlled with suitable strategy to avoid the quench of the superconducting magnet. These four power supplies are used to supply four superconducting solenoids. Because the value and the changing rates of the current for these four solenoids are different, the power supplies must be operated synchronously to keep the current of the solenoids balanced. In this paper, we provide a detailed description for the control strategy of the four power supplies and the architecture of the hardware and the software. A serial switch is used for protocol conversion between TCP/IP and RS232 in firmware. And the software is implemented using VC++. The system can operate the four power supplies automatically after it is triggered. With the help of the control system, operation of the SMPS gets easier and safer.
