Thermal power plants are used to generate power. They are designed based on the required conditions, but actually inlet conditions are not as per the designed conditions. Variations in the power outputs from the power plant are always a matter of dispute. So correction curves for power and heat rate are generated. In this paper, a thermodynamic analysis of 120 MW thermal power plant was done at a particular inlet pressure (127.06 bar) and at different condenser back pressures (0.068 bar, 0.088 bar, 0.1015 bar, 0.107 bar, 0.127 bar and 0.142 bar). The correction curves for power and heat rate were generated for the combined effect of constant inlet pressure and different condenser back pressures. These curves indicate that if inlet pressure is 127.06 bar and condenser back pressures vary, simultaneously power output and heat rate also vary.
