火力发电厂输煤控制系统概述

Summary of Automatic Control of Coal Transporting System in Thermal Power Plant

所谓一体化控制,就是把工业电视监视系统、排污设施控制、除尘装置控制和输煤设备控制纳入到一个PLC控制系统,充分利用其大容量、运算速度快、性能稳定可靠和主从控制功能。可以根据输煤系统占线长的特点,以区域为依据设立几个控制从站,在主控室设立主控制站,从而实现输煤系统的一体化控制。

Incorporate control is to put the industrial supervising system,the control of dust catcher and the control of transporting coal together into one PLC. The ability of PLC with large memory,high speed of calculation and brilliant reliability can be utilized. Accoring to the speciality of the coal transporting system which covers long distance,we set up several slave control stations at different area and a master control station in master control room,so the incorporate control of the coal transporting system is realized.
