Abstract

Triple shaft gas turbines are the most gas compressor driven in natural gas compressor station in national Iranian Gas Company. In the recent study, exergy equilibrium formula of each components of gas compressor station specified and several mathematical models made. The model predict different parameters based on environmental and operational conditions. Models made by multivariate linear regression and ANOVA technique that made high precision models. The models results show that how varying the environment and operational condition such compressor inlet temperature, turbine inlet temperature and turbine pressure ratio affect exergy efficiency, fuel consumption, exergy destruction and specific fuel consumption. In this study effects of environmental and operational variables on this parameters and interaction of this variable on each other surveyed. Results showed that variation in each variables has no effect in slope of net output power variation due to change in other variables, whereas compressor inlet temperature and pressure ratio in exergy efficiency model, turbine inlet temperature and pressure ratio in fuel consumption model and turbine and compressor inlet temperature in specific fuel consumption model have interaction on their model's response
