摘要
通过对FDQ-100型水电解制氢设备控制系统进行升级改造,将原有气动控制升级为PLC软件控制,配备上位机显示及远程控制,可同时显示系统运行情况、报警点位,并绘制系统运行压力、温度、氢氧侧液位等曲线。在增加安全连锁保护的同时,大大提高了调解指令控制精度与故障排除效率,消除了因原控制系统老化带来的液位波动安全隐患,提升了制氢系统的运行稳定性。同时,控制系统优良的扩展性能为进一步提高制氢站的安全运行奠定了基础。
Through the upgrade of a FDQ-100 type water electrolysis hydrogen production equipment control system,theoriginal pneumatic control was transformed to PLC control and the system was equipped with PC display and control.At thesame time,a security chain protection was added,which has greatly improved the accuracy of the mediation and efficiencyof fault elimination.The excellent performance of the new control system provides a foundation for further improvement ofthe safe operation of hydrogen production stations.
