摘　　要：介绍了合肥同步辐射光源(HLS)50MW大功率速调管脉冲调制器改造项目。在该项目中,采用可编程控制器(PLC)监控系统取代了原有的基于继电器逻辑电路的监控系统,使其成为HLS基于先进的控制软件EPICS的新控制系统的一部分,采用恒流逆变充电电源取代了原来的工频高压电源,使调制器技术更先进、运行更加可靠。本文给出了调制器PLC控制系统的设计方法和软硬件的实现及运行情况。Upgrade project of the 50 MW klystron modulators of Hefei Light Source (HLS) was firstly introduced. PLC control system of modulators was employed to replace the old control and monitor system, which was based on relay logic circuit and manual operation method. The PLC system becomes a sub system of the new EPICS control system of HLS. Constant-current, switch-mode and high voltage power supplies were adopted to replace the old 50 Hz power supplies. The technology of modulators was improved and operation was more reliable. The design method, hardware and software of PLC control of modulators were described and the performance was presented.
