Abstract

Purpose: This study aims to evaluate the performance of the steam turbine unit at Bablean Coal-Fired Power Plant or Pembangkit Listrik Tenaga Uap (PLTU) Bablean, analyzing its output power, heat rate, and turbine efficiency compared to the design specifications.

Research Methodology: The performance test was conducted following the ASME PTC 6 standard, with parameters including capability tests, heat rate calculations, and turbine efficiency assessments. Data was collected weekly from May to August 2020, during the base-load operation of the steam turbine.

Results: The results show that the output power, heat rate, and turbine efficiency during the actual data collection were within the tolerance limits set by ASME PTC 6. The actual turbine efficiency was higher than the design specification, largely due to a lower turbine exhaust pressure.

Conclusions: The performance test revealed that the steam turbine at Bablean coal-fired power plant is operating within acceptable limits, and maintaining low turbine exhaust pressure is crucial to optimizing turbine efficiency.

Limitations: The study focused on the performance testing of the turbine unit during base-load conditions and may not reflect performance under varying operational loads.

Contributions: This research provides valuable insights into the optimization of turbine performance and offers recommendations for improving efficiency through maintenance practices, particularly concerning turbine exhaust pressure.
