Abstract

A method for power plant Gas Turbine overall performance evaluation was developed based on the thermodynamic cycle. Some key parameters affecting the simple cycle efficiency and power of the GT, such as compressor pressure ratio, turbine inlet temperature, compressor efficiency, compressor exit diffuser Cp, combustor pressure loss, turbine efficiency, OTDF, RTDF, blade metal allowable temperature and turbine exit diffuser Cp has been studied across a wide range of possible operating conditions. The effects on simple cycle of GT efficiency, GT specific power and turbine exit temperature of these parameters were discussed: The compressor pressure ratio should be chosen to give an optimumGT specific power, and should match turbine inlet temperature; When compressor efficiency increases 1%, the GT efficiency increases about 0.3%, while turbine efficiency increases 1%, the GT efficiency increases about 0.6%; When compressor exit diffuser Cp increases 0.1, the GT efficiency increases about 0.1%, while turbine exit diffuser Cp increases 0.1, the GT efficiency increases about 0.25%; RTDF is more important than OTDF for GT efficiency, When RTDF increases 0.05, the GT efficiency decreases about 0.15%, but When OTDF increases 0.05, the GT efficiency only decreases about 0.02%; When combustor pressure loss increases 1%, the GT efficiency decreases about 0.2%, but combustor pressure loss also effect turbine Nozzle1 cooling design; these parameters should be carefully considered in a new GT design.
