随着以大容量、高参数为特点的发电技术的进步 ,火电机组正朝着大容量、超临界方向发展 ,要实现电力系统的安全稳定运行 ,必须不断增加发电厂的自动控制功能和提高其自动控制水平。我国目前火力发电厂的自动化水平较以前有了很大的进步 ,但是与国外相比 ,尚有较大的差距 ,大力 With the progress of power generation technology characterized by large capacity and high parameters, thermal power units are moving toward large capacity and supercritical. To achieve safe and stable operation of power systems, it is necessary to continuously increase the automatic control functions of power plants and improve their Automatic control level. At present, the level of automation of thermal power plants in our country has been greatly improved compared with the previous ones. However, compared with other countries, there is still a large gap between the two.
