摘　　要：某电厂9F级燃气-蒸汽联合循环机组为多轴二拖一结构,额定出力780 MW。机组配备高压、中压、低压三级旁路,其中高、中压旁路采取串联布置的方式,不同于单轴联合循环机组普遍采用的旁路并联布置方式。针对旁路的串联布置,并结合"二拖一"的机组形式,介绍分析旁路系统的控制特点,供相关类型机组参考借鉴。The first 9F multi-shafts （2 ＋ 1） combined cycle unit of china was installed in a power plant. The unit, whose rated output is 780 MW, has HP, IP and LP bypass, with cascade type. This is different from parallel bypass, which is mostly used in combined cycle in china. Considering the cascade type and ＂Two Plus One＂ unit structure, some control characteristics are presented and analyzed, may give reference to similar units.
