Abstract
The government builds power Plants with adequate capacity and quantity to meet human needs. In the process of generating electricity does not always run well. This study aims to improve the efficiency of the operational process by minimizing the Heat rate value that occurs in the PLTGU unit using the Energy Value Steam Mapping (EVSM) and Failure Mode And Effects Analysis (FMEA) methods. The results of the study showed that the high heat rate in Gas Turbine 1.1 and Steam Turbine was caused by fouling in the Compressor Gas Turbine, Corrosion or material damage to the HP Evaporator HRSG, and leakage in the Steam Turbine condenser. The overall heat rate in the block I generating unit before the repair was 1,432.63 kcal/kwh. Then after the proposed repair projection, it was only 830.63 kcal/kwh. This means that there is a decrease in the heat rate in the operational process of 602.01 kcal/kwh or a percentage of 42.02%.
