发电厂输煤控制系统的研究与改进

Rebuilding of Coal Conveying Control System of Power Plant

对可编程控制器应用于电厂输煤控制系统进行了研究。结合阳逻电厂原输煤控制系统 ,提出了一种建立基于可编程逻辑控制器 (PL C)的控制器网络的改造方案 ,改造后的输煤系统有强大的监控功能 ,同时也具备了与 MIS联网的能力。

programmable Logic Controller(PLC) is gradually applied to the coal system of power plants. Taking as an example of the coal conveying control system in the Yangluo power plant, a rebuilding plan of the controller link net based on PLC is proposed in the paper. The rebuilded system has functions of monitoring and linking with MIS. The scheme of the assigning coal is also introduced.
