摘要
近年来随着输煤系统自动化水平的日益提高,PLC系统在火电厂输煤系统中得到了更广泛的应用。PLC不仅能完成复杂的继电器逻辑控制,也能完成智能控制与模拟量控制,极大提高了输煤系统的智能化与自动化。为此,首先介绍了火电厂输煤控制系统的特点,随后重点探讨了基于PLC的输煤系统设计,以期进一步提高火电厂的工作效率,尽量减少对工作人员健康的损害。
In recent years, with the increasing automation level of coal conveying system, PLC system has been widely used in coal conveying system of thermal power plant.PLC can not only complete complex relay logic control, but also complete intelligent control and analog control, greatly improving the intellectualization and automation of coal conveying system.Therefore, this paper first introduces the characteristics of coal conveying control system in thermal power plant, and then focuses on the design of coal conveying system based on PLC, in order to further improve the efficiency of thermal power plant and minimize the damage to staff health.
