摘　　要：茂名热电厂升压水泵及液控止回蝶阀控制回路存在接线复杂、维护困难、工作可靠性差及自动化水平低的问题。在DCS改造中,通过就地安装远程控制柜,用远程光纤接入#3、4机组DCS系统的方法,实现了升压水泵及液控止回蝶阀的DCS控制改造,使其作为#3、4机组DCS系统的一个子系统,大大提高了自动化水平。There are some problems of the pressure-rising pump and hydraulic butterfly check valve in Maoming Cogeneration Power Plant, such as the complexity of connection, the difficulty of maintenance, the low reliability and the low automation level. This paper presents an Improvement scheme in detail. In this scheme, by installing control cabinet, #3 unit and #4 unit can be accessed through remote fiber. Thus the upgrade on DCS of the pressure--rising pump and hydraulic butterfly check valvew, which is a subsystem of #3 unit and #4 unit DCS system, is realized. Practical application shows that this scheme greatly improves the level of automation.
