PURPOSE: A method for calculating/graphing data to measure performance of a gas turbine is provided to precisely and easily analyzing the performance of the gas turbine by determining conditions of each part of a compressor, a combustor, and the gas turbine based on weather data and site elevation information, and calculating/graphing the data to measure the performance based on the conditions. CONSTITUTION: The site elevation information and the weather data are inputted(S301). A combustion ratio of the air and fuel is determined by analyzing a fuel and composition of the fuel(S302). A pressure loss of the air at a compressor inlet and the pressure loss of the gas at a turbine outlet are determined by using stored pressure loss data of each model(S303). A modified air temperature, which is the air temperature at a site elevation, is calculated by using the site elevation information and the weather data(S304). The pressure at the compressor inlet is calculated by using the air pressure, the pressure loss at the compressor inlet, and the modified air temperature(S305). A wet air pressure of the air temperature is calculated by using a saturated pressure and the site elevation(S306). |
