无线通信技术在发电厂输煤程控系统中的应用研究

Research on the Application of Wireless Communication Technology in Coal Transmission Program Control System of Power Plant

在火力发电厂中,输煤程控系统在公用系统控制中占有举足轻重的地位。传统的输煤远程控制站与煤场的斗轮机PLC之间,都是采用有线通信的方法来实现信号传输。但是因为斗轮机的取煤位置不断改变,所以控制信号电缆被拉断等的情况经常发生,这将会对机组上煤造成很大程度的不利影响。而将无线通信技术应用到火力发电厂的输煤程控系统中,可以让这一问题得以有效解决。本文就是对该技术在火力发电厂输煤程控系统中的应用进行研究。

In the thermal power plant,the coal transmission program control system plays an important role in the public system control. The traditional remote control station of coal transport and the bucket turbine PLC of coal yard adopt the method of wire communication to realize the signal transmission. However,because the coal extraction position of the bucket turbine is constantly changing,the control signal cable is often pulled,which will cause a great degree of adverse impact on the coal unit. The application of wireless communication technology to the coal transmission program control system of thermal power plants can effectively solve this problem. This paper is to study the application of this technology in the coal transmission program control system of thermal power plant.
