ABSTRACT
A Steam Power Plant (PLTU) is a power generation system that operates based on the Rankine cycle, converting thermal energy from fuel combustion into electrical energy. Over time, the performance of a PLTU decreases due to the degradation of major components such as the boiler, turbine, pump, and generator. To restore and improve plant performance, an overhaul is conducted, involving repair, replacement, and recalibration of critical components.This study aims to analyze the performance of the PLTU before and after the overhaul, focusing on individual component efficiencies, overall thermal efficiency, and heat rate. Operational data were obtained from the Distributed Control System (DCS) and analyzed using a thermodynamic approach based on enthalpy and entropy parameters of the Rankine cycle. Calculations were performed for the main components of the cycle, namely the pump, boiler, turbine, and generator, and the results were compared between pre-overhaul and post-overhaul operating conditions.The results indicate an improvement in plant performance after the overhaul. The heat rate decreased from 11,944.26 kJ/kWh to 8,689.35 kJ/kWh, while the thermal efficiency increased from 30.14% to 41.43%. Pump efficiency increased from 54.53% to 79.13%, boiler efficiency improved from 46.09% to 48.61%, and turbine efficiency rose from 81.38% to 90.00%. The generator efficiency showed a slight increase from 91.46% to 92.00%. Overall, the overhaul was proven to be effective in enhancing energy conversion efficiency, reducing fuel consumption, and improving the operational reliability of the power plant.
Keywords: Component Efficiency, Heat Rate, Overhaul, Rankine Cycle, Steam Power Plant, Thermal Efficiency.
