摘　　要：为了解决某火电厂原有输煤控制系统存在的诸多问题,对输煤控系统进行重新设计,开发一个基于树形结构算法的输煤DCS控制系统,增加了大连锁及手动标识、自动配煤等,经过长时间使用发现机组运行稳定,实现了配煤掺烧,降低了生产成本,提高了设备安全系数与经济效益。In order to solve many problems existing in the original coal transportation control system of a thermal power plant, the coal transmission and control system is redesigned, a coal transmission DCS control system based on tree structure algorithm is devel. oped, the large chain and manual identification, automatic coal blending are added, and the unit is stable after long use, and the coal blending is realized, which reduces the production cost , and improves the safety factor and economic benefit of the equipment.
