Abstract:
Along with the completion of the “West-East” project in China,as well as the construction of the “gas transmission from Sichuan province to eastern provinces” and the further development of gas in East China Sea,combined cycle power plants(CCPPs)have been developed quickly in the past couple of years.The traditional evaluation method based on the first and second law of thermodynamics does not consider the influence of non-energy cost.Firstly,the cost model of CCPP is established based on the thermoeconomic structural theory.Secondly,considering the importance of internal parameters,two internal parameters,such as compressor pressure ratio and the outlet temperature of gas turbine, are selected and investigated when designing the CCPP.Lastly,considering regional difference and seasonal difference,the way how the natural gas price change and environment temperature influence on the CCPP’s generating cost are studied respectively.These researches will support the thermoeconomic optimization of CCPP and provide a reference for investors or policy makers.
