Effect of Ambient Temperature on Three-Shaft Gas Turbine Performance under Different Control Strategy

Abstract:

Gas turbine is sensitive to ambient temperature. Different ambient temperature could change the state of the inlet air of compressor and make the gas turbine work in off design conditions. Research the effect of ambient temperature on gas turbine performance is valuable to the long-term safe operation of gas turbine. In this paper, a thermodynamic model of a simple cycle gas turbine which has three shafts was established, and steady-state performance simulation under different ambient temperature was carried out. In the two conditions of 1.0 and 0.35 work states, the effect of ambient temperature on thermodynamic parameters, specific power and thermal efficiency of gas turbine were analyzed. The result shows that: effect of ambient temperature on three-shaft gas turbine is different under different work state, and relevant factors must be considered to select the appropriate control strategy
