PLC在石灰石制粉控制系统中的应用

摘要

由于PLC具有操作简单、灵活,可靠性好等特点,那些独立的控制单元或信号比较集中的系统,大都采用PLC进行过程控制.该文以电厂烟气脱硫系统中的石灰石粉制备控制系统为例,主要介绍了其控制系统的软、硬件配置,软件设计,实现方式,控制过程等.%As the PLC is simple, flexible, reliable, most of process control by PLC has been used in separate control unit or signal more centralized system. In this paper, limestone milling system of gas desulfurization system in power plant as an example, it introduces software and hardware configuration, software design, implementation, and control processes of the control system.
