Analisis keandalan pembangkit listrik di anjungan minyak lepas pantai central plant PT. Pertamina Hulu Energi ONWJ
K Keandalan unit pembangkit merupakan kemungkinan suatu unit pembangkit dapat bekerja pada suatu periode tertentu, keandalan unit pembangkit dapat di lihat dan beberapa aspek salah satunya loss of load probability. Untuk mendapatkan nilai loss of load probability memerlukan data mengenai beban pada sistem selama periode tertentu dan data mengenai jam operasi generator bekerja selama periode tertentu. Penelitian ini membahas keandalan pembangkit listrik di anjungan minyak lepas pantai PT Pertamina Hulu Energi ONWJ dengan menghitung nilai loss of load probability dan menghitung rating generator berbasis waktu. Dari penelitian yang sudah dilakukan didapat nilai loss of load probability sebesar 0.17015 hari/tahun. Untuk menekan nilai loss of load probability maka harus mengurangi waktu perawatan generator.
T The reliability of the power unit is the possibility of a power unit can work in a given period, the reliability of generating units can be seen from several aspects, one of which loss of load probability. To get the value of the loss of load probability require data about the load on the system during a certain period and data regarding hours of operation the generator at offshore platform PT Pertamina Hulu Energi ONWJ by calculating the value of the loss of load probability and counting time based generator rating. From the research that's been done had the value of loss of load probability of 0.17015 days / years. To suppress the value of the loss of load probability, then it should reduce maintenance time generator.
