继2000年燃煤示范电站之后,一大批高参数、大容量的火电机组正在建设中,大型火电厂自 动化设计又出现了一些新的技术和问题。文中针对现阶段大型火电厂自动化设计的热点问题,包 括“多机一控”控制方式、机组自启停功能、闭环优化控制软件、现场总线控制系统、空冷控制系统、 脱硫控制系统、脱硝控制系统等方面进行了讨论,并给出了建议。
Following the coal-fired demonstration power station in 2000, a large number of high-parameter and large-capacity thermal power units are under construction. Some new technologies and problems have emerged in the automation design of large thermal power plants. In this paper, the hot issues of large-scale thermal power plant automation design at present are discussed, including “multi-machine and single-control” control mode, self-starting and stopping function, closed loop optimization control software, fieldbus control system, air cooling control system, desulfurization control system, And other aspects of the discussion, and gives suggestions.
