二拖一燃气-蒸汽联合循环发电机组自启动功能的设计与应用

Auto-start function of two-to-one IGCC unit:design and application

针对某二拖一燃气-蒸汽联合循环机组自启动功能运行方式多样、工艺流程可变的特点,设计了二拖一燃气-蒸汽联合循环机组的自启动程序。通过选择1号机组和2号机组的启动顺序,设置合理的并汽顺序,从而使得该程序能够很好地适应二拖一机组的运行特点,实现机组的全自动启动。

On the basis of the characteristics of a gas-steam combined cycle （IGCC）unit,such as variety in operation mode and variability in process,the auto-start program was designed. Through choosing the start sequence of No.1 and No.2 unit,reasonable steam combination sequence was set.Thus,this program can meet the requirements of variety in operation mode for this unit,which helps the unit itself realize auto-start.
