摘要
Abstract
As for the PG6111FA(6FA)gas turbine made by General Electric(GE)Company,runback or tripping often occure during combustion mode transfer due to combustion dynamics instability or high exhaust temperature spread,especially when the unit operation model is transfering from Mode_3 to Mode_6.The general situation of 6FA gas turbine combustion system and the causes of runback and tripping were analized,and the above problems were solved by setting reasonable increase and decrease load values,strengthening monitoration of combustion dynamics,as well as raising the fuel temperature and optimizing the protection logic.The research results can provide reference for operation control of 6FA gas turbines and units with DLN2.6 combustion control system during combustion mode transfer.关键词
