"Significant changes over the past decade in computing technology, along with widespread deregulation of electricity industries, have impacted on power plant operations while affording engineers the opportunity to introduce monitoring and plant-wide control schemes which were previously unfeasible. Contributors of world-class excellence are brought together in Thermal Power Plant Simulation and Control to illustrate how current areas of research can be applied to power plant operation, leading to enhanced unit performance, asset management and plant competitiveness through intelligent monitoring and control strategies."

"ULPLTG Maleo merupakan pembangkit listrik dengan 4 unit mesin turbin gas berkapasitas 25 MW yang memiliki peranan penting dalam memberi pasokan energi listrik kepada sistem SULUTGO. Keandalan dan kesiapan unit menjadi prioritas bagi perusahaan. Selama ini ULPLTG Maleo tidak memiliki standar dalam melaksanakan pemeliharaan terhadap mesin yang mengalami shutdown dalam jangka waktu lama. Riwayat pemeliharaan unit menunjukkan adanya temuan korosi dan white spot pada blade compressor main engine sehingga perlu ditentukan tindakan mitigasi yang tepat. Berdasarkan hal tersebut pelaksanaan praktik keinsinyuran ini bertujuan untuk merencanakan metode preservasi yang dapat diterapkan sesuai dengan riwayat peralatan dan kondisi lingkungan di ULPLTG Maleo. Berdasarkan pengujian yang dilakukan dapat diketahui bahwa penerapan metode preservasi yang dilakukan memberi pengaruh terhadap perbandingan nilai temperatur dan kelebapan serta menjaga nilai kelembapan port borescope inspection nomor 4 selalu pada nilai %RH terendah namun masih dipengaruhi oleh temperatur dan kelembapan lingkungan ULPLTG Maleo. Hasil pemeriksaan borescope menunjukkan tidak terjadi perubahan kondisi korosi dan white spot yang signifikan pada blade stage 1, 2 dan 16 namun pada blade stage 2 terjadi penurunan tingkat white sport secara minor sehingga dapat disimpulkan pelaksanaan preservasi yang dilakukan kurang efektif dalam mengatasi permasalahan utama.

ULPLTG Maleo is a power plant which plays an important role in providing electrical energy to the SULUTGO system. The unit's maintenance history shows the presence of corrosion and white spots on the main engine compressor blade, so appropriate mitigation measures need to be determined. Based on this, the implementation of this engineering practice aims to plan preservation methods that can be applied by the history of the equipment and environmental conditions at ULPLTG Maleo. Based on the tests carried out, it can be seen that the application of the preservation method has an influence on the comparison of temperature and humidity values ​​and maintains the humidity value of port borescope inspection number 4 always at the lowest %RH value but is still influenced by the temperature and humidity of the Maleo ULPLTG environment. The results of the borescope examination showed that there was no significant change in the condition of corrosion and white spots on blade stages 1, 2 and 16. However on blade stage 2 there was a minor decrease in the level of white sport, so it can be concluded that the preservation implementation carried out was less effective in overcoming the main problem."

"ABSTRAKKetersediaan sistem pembangkit tenaga listrik dipengaruhi oleh keandalan suku cadang dan manajemen pemeliharaan yang berdampak pada maintainability.

ABSTRACTAvailability of thermal power plant is influenced by the reliability of spare parts and maintenance management that affect maintainability. RCM Reliability Centered Maintenance , RBM Risk Based Maintenance , and CBM Condition Based Maintenance or combined RCM and RBM or RCM and CBM have been applied in thermal power. Each maintenance technique will generate each maintenance work packages. Implementation of RCM, RBM and CBM maintenance techniques in an integrated manner will result in maintenance work packages that will increase the availability of power plants more significantly than the use of each maintenance technique or a combination of two maintenance techniques. This research integrates maintenance techniques based on reliability, risks and conditions, called Integrated Maintenance Techniques TPT , which consists of 10 steps determining function tree, operation records, FMEA Failure Mode Effect Analysis , FTA Fault Tree Analysis , risk analysis, which then produce MPI Maintenance Prioritization Index , FDT Failure Defense Task , integrated maintenance program conducted by condition monitoring assessment, reliability maintainability analysis and results. This research developed a mathematical model, and then performed a simulation to analyze the availability produced by each maintenance technique. Availability of RCM, RBM, CBM and TPT is as follows 81.56 , 81.02 , 84.92 , and 90.07 . The implementation of TPT in thermal power plant of research object has resulted in an increase of thermal power plant availability from 76.95 2008 2012 or 81.84 2010 2012 to 92.59 2013 May 2015 ."
