Combined cycle power plant (CCPP) is a very large and complex thermal system. It is very difficult to assess the factors which affect the power plant performance higher than other factors with the help of thermodynamic model. Graph theory is a new approach which is easy to implement and compatible with computer programming. This paper presents a methodology for the assessment of critical component of a CCPP on the basis of efficiency. It is being found that combustion chamber is the most critical factor which affects the CCPP performance. For the present analysis a digraph is developed considering the attributes affecting the efficiency of CCPP. The sensitivity analysis of the attributes towards the objective has also been carried out in order to study the impact of attributes over the desired outcome. A methodology is developed for the assessment of order affecting the CCPP performance. Results obtained are compared with the data available in the literature and they are found in good agreement with it.

Abstract


Combined cycle power plant (CCPP) is a very large and complex thermal system. It is very difficult to assess the factors which affect the power plant performance higher than other factors with the help of thermodynamic model. Graph theory is a new approach which is easy to implement and compatible with computer programming. This paper presents a methodology for the assessment of critical component of a CCPP on the basis of efficiency. It is being found that combustion chamber is the most critical factor which affects the CCPP performance. For the present analysis a digraph is developed considering the attributes affecting the efficiency of CCPP. The sensitivity analysis of the attributes towards the objective has also been carried out in order to study the impact of attributes over the desired outcome. A methodology is developed for the assessment of order affecting the CCPP performance. Results obtained are compared with the data available in the literature and they are found in good agreement with it.
