열병합 발전소의 구성안별 성능 평가 방안-플랜트 열성능 및 단순화 발전단가 분석Performance Evaluation of Combuined Heat and Power Plant Configurations-Thermodynamic Performance and Simplified Cost Analysis
Thermodynamic and economic analyses of various types of gas turbine combined cycle power plants have been performed to establish criteria for optimization of power plants. The concept of efficiency, in terms of the difference in energy levels of electricity and heat, was introduced. The efficiency of power and heat generation by power plants with other purposes was estimated, and power generation costs were figured out for various types of combined heat and power plants(i.e., fired and unfired, condensing and non-condensing modes, single or double pressure HRSG).
