摘要(Abstract)：

大型火力发电机组锅炉大多采用直吹式制粉系统,在机组的AGC运行控制中,尚无法实现自动过渡磨煤机启/停断点,给运行人员人工预判和操作带来了判断时机难、操作压力大,汽温、汽压和负荷频繁波动等问题。TOP(电站热工优化控制平台)系统智能AGC优化组件通过磨组实时带载能力监控、电网负荷时间趋势预判、启磨窗口自适应调整、机组运行状态优化控制等技术,能准确给出磨组启停时机和磨组启停顺序,实现了机组AGC连续自动运行。
At present,most of boilers of the domestic large thermal power generating units use direct-fired pulverizing system.In operating control of AGC of units,automatic transition to startup or shutdown breakpoint can not be implemented yet,which brings problems such as difficult in determination,big operating pressure,frequent fluctuations of steam temperature,steam pressure and load to manual determination and operation of the operators.By monitoring on real-time load capacity of pulverizer group,judgment of grid load time trend,self-adjustment of pulverizer startup hatch and optimized control of unit operating status,the intelligent AGC optimization module on power plant thermal optimized-control platform can accurately display the startup/shutdown time and the sequence of pulverizer group,enabling continuous automatic operation of AGC on thermal power plant.
