Abstract

Generator merupakan salah satu peralatan kelistrikan yang berfungsi untuk membangkitkan daya listrik dengan mengonversi energi mekanik. Bagi perindustrian, menjaga keandalan dari generator sangat penting karena kegagalan suplai daya dapat menimbulkan kerugian yang tinggi. Keandalan dari suatu generator dapat ditingkatkan dengan melakukan pemilihan dan pengaturan dari skema proteksi yang tepat. Plan Smelter Nikel di Sulawesi Selatan merupakan perusahaan penambang nikel laterit untuk menghasilkan produk akhir berupa nikel dalam matte. Saat ini, salah satu penyuplai kebutuhan listrik tersebut adalah PLTA Karebbe (2 x 66,3 MW). Dengan pengaturan yang ada, khususnya terhadap sistem proteksi generator di PLTA Karebbe (2 x 66,3 MW), ketika terjadi gangguan pada jaringan 150 kV peristiwa black out masih terjadi. Peristiwa tersebut mensinyalir bahwa ada miskoordinasi dari rele proteksi dan pengaturan sistem proteksi internal generator yang belum sesuai standar. Oleh karena itu, dibutuhkan adanya evaluasi terhadap pengaturan tersebut agar peristiwa blackout dapat diminimalisasi, sehingga generator dapat menyuplai daya secara kontinu. Hal ini dilakukan dengan melakukan simulasi Load Flow dan Short Circuit dari sistem kelistrikan Plant Smelter Nikel di Sulawesi Selatan pada ETAP 19 dan melakukan perhitungan dan penyesuaian pengaturan rele dengan standar dengan menggunakan Excel. Hasil penelitian tersebut dapat dijadikan rekomendasi untuk pengaturan sistem proteksi internal generator Plant Smelter Nikel di Sulawesi Selatan.

A Generator is an electrical equipment that functions to generate electrical power by converting mechanical energy. In the industry, maintaining the reliability of the generator is very important. This is due to the high amount of losses because the failure of the power supply can cause high losses. The reliability of a generator can be improved by selecting and setting up the right protection scheme. The nickel smelting company at South Sulawesi is a laterite nickel mining company that produces nickel matte. Currently, one of the electricity suppliers is the Karebbe Hydroelectric Power Plant (2x66,3 MW). With the existing arrangements, especially for the generator protection system at Karebbe Hydroelectric Power Plant (2x66,3 MW), when there is a disturbance in the 150 kV network, black out events still occur. This is due to the miscoordination of protection relays and the generator's internal protection system settings that are not up to standard. Therefore, an evaluation of these settings is needed so that blackout events can be minimised, so that the generator can supply power continuously. This is done by simulating the Load Flow and Short Circuit of the nickel smelting company’s electrical system in ETAP 19 and calculating and adjusting the relay settings to the standard through Excel. The results of this research can be used as recommendations for setting up the internal protection system of the the nickel smelting company’s generator.
