Research on inlet heating control method of GE gas turbine in multi-axis combined cycle unit
Due to the poor control effect of the control algorithm,the heating cannot reach the heating temperature in a short time,and the generating power is low.Therefore,a GE gas turbine inlet heating control method of multi-axis combined cycle unit is studied.In this study,natural gas is taken as the intake gas of GE gas turbine in multi-axis combined cycle unit,and a GE gas tur-bine intake heating control scheme is proposed that combines both intake cooling and intake heating.In this scheme,performance heater is used for intake heating control,and the performance heater is washed before the performance heater is heated to make the water-side pipeline enter the hot standby state and avoid the omission of water-side pipeline.In the heating control stage,PID algo-rithm is used to realize the inlet heating control of GE gas turbine in multi-axis combined cycle unit.The experimental results show that this method can make GE gas turbine intake temperature reach the target temperature in a short time.The application of this method can improve the generation power and efficiency of GE gas turbine of multi-axis combined cycle unit.When the inlet heating temperature is 35℃,the load rate of combined cycle unit decreases and the generation efficiency increases to the greatest extent.
