Steady-state modelling and validation of a thermal power plant

Abstract

In the present work, steady-state modelling and validation of a 210-MW sub-critical thermal power plant located in North India using mass, energy, and exergy balance equations. The first and second law efficiencies have analysed for each component. MATLAB calculation tool and Engineering Equation Solver (EES) software have used for performing analyses. The results conclude that 277.2 MW (72.50%) of the total energy lost in the condenser as the main equipment wasting energy to the environment followed by boiler with 101.4 MW (26.52%) in the cycle. On the other hand, the maximum exergy destruction is seen to be in the boiler system 274.48 MW (85.64%) followed by the other components. The calculated thermal efficiency and the exergy efficiency of the overall plant are found to be 36.60 and 35%.
