摘　　要：针对某PG9171E燃气轮发电机组降负荷过程中,燃烧模式切换从预混稳定模式(PMSS)到贫贫模式(LEAN-LEAN),发生负荷突变现象,通过记录曲线、软件的计算和燃料喷嘴的流量测量的事实,分析了流量和负荷波动之间的关系。结果表明:一次喷嘴的流量和负荷波动有着直接的关系。For a PG9171E gas turbine generator unit load down, in the process of the combustion mode transfer from the pre-mixed stable mode （PMSS） to LEAN-LEAN mode, and the load mutation phenomenon was occurred, the relationship between flow rate and load fluctuation is analyzed by recording trends, software calculation and flow measurement of fuel nozzle.The results show that there is a direct relationship between flow rate and load fluctuation of a nozzle.
