[摘 要]运煤系统作为火电厂的重要组成部分,具有设备种类多、数量多、分布广以及工艺流程复杂的特点,这就导致人工控制模式已经难以满足火电厂运煤系统的实际管理需求。因此我国火电厂还需要在结合自身运行特点基础上,加强运煤系统的自动化建设力度,提高运煤自动化系统的智能化和信息化水平,这样才能充分发挥火电厂运行系统的作用,对火电厂运行效益的提升也有着非常重要的意义,本文主要就火电厂运煤系统的自动控制进行探究分析。

[Abstract]As an important part of the thermal power plant, the coal transportation system also has the characteristics of a large variety of equipment, a large number, a wide distribution, and a complex process flow. As a result, the manual control mode has been difficult to meet the actual management needs of the coal transportation system in the thermal power plant. Therefore, my countrys thermal power plants also need to strengthen the automation construction of coal transportation systems based on their own operating characteristics, and promote the intelligentization and informatization of coal transportation automation systems, so that the role of the thermal power plant operating system can be fully realized. It is also of great significance for the improvement of the operating efficiency of thermal power plants. This article mainly explores and analyzes the automatic control of the coal transportation system in thermal power plants.

運煤系统的运行可靠性与灵活性会直接影响到火电厂的运行效果,但是在以往的运煤系统中多是采用继电器控制方式,自动化水平不足,难以满足火电厂的实际生产需求。近年来,随着可编程控制器以及计算机通信技术的不断发展,基于远程I/O以及PLC程序的控制方式也得到了比较迅速地发展,对于火电厂运煤系统自动化控制水平的提升也有着一定的积极意义。因此我国火电厂还需要加强对运煤系统的不断优化与完善力度,让运煤系统的自动化控制水平进一步提升,充分发挥运煤系统和火电厂的作用。
1 进行运煤系统自动化控制的必要性
随着火电厂的迅速发展,对运煤系统的运行效果也提出了更高的要求,传统的继电器控制模式已经难以满足运煤系统的实际管理需求。……
