摘要
主要阐述了PLC控制系统在氢气透平压缩机仪表控制系统改造过程中的应用,并通过通讯接口将透平压缩机的PLC与加氢装置的DCS融为一体,提高整个加氢装置的自动控制水平。
It is mainly introduced that PLC control system was applied in the automatic control system of hydrogen turbine compressor. And the DCS of the hydrogenation and the PLC of the turbine compressor are melted into one part by a communication port, raising the auto control level of the whole hydrogenation unit.
