Evaluasi Kinerja dan Efisiensi Generator Sebelum dan Sesudah Overhaul pada PLTP Unit 1 PT. XYZ

Abstract

Kinerja generator pada PLTP Unit 1 PT. XYZ mengalami beberapa kendala operasional seperti derating, penghentian unit, dan keterlambatan perawatan yang dapat menurunkan efisiensi pembangkitan. Penelitian ini bertujuan untuk mengevaluasi efisiensi generator sebelum dan sesudah overhaul serta menganalisis perubahan kinerja generator berdasarkan parameter operasional dan termodinamika. Penelitian menggunakan pendekatan kuantitatif deskriptif dengan data operasional generator dan sistem uap yang dikumpulkan selama 14 hari sebelum dan sesudah overhaul. Parameter yang dianalisis meliputi daya generator, faktor daya, tekanan uap, laju aliran massa uap, entalpi, dan entropi. Hasil penelitian menunjukkan bahwa sebelum overhaul daya rata-rata generator sebesar 46,36 MW dengan efisiensi rata-rata 89%, sedangkan setelah overhaul meningkat menjadi 50,38 MW dengan efisiensi rata-rata 96%. Peningkatan efisiensi menunjukkan bahwa proses overhaul berkontribusi terhadap perbaikan kinerja generator dan sistem pembangkitan secara keseluruhan.
