During the operation of a gas turbine generator set,the decrease in compressor efficiency will directly affect the power generation efficiency,and the efficiency of the compressor during operation has a significant impact on the efficient operation of the unit.Summarized the current testing and calculation methods applicable to the efficiency of compressors in gas turbine generator sets,and provided calculation formulas for the constant specific heat process and variable specific heat process.A compressor test was conducted on a certain F-class gas turbine generator set currently in operation at different load stages.The efficiency of the com-pressor was calculated using the process calculation methods of fixed and variable specific heat capacities.There was a deviation in the calculation results of fixed and variable specific heat,and the deviation gradually increased with the increase of pressure ratio.
