Abstract

Energi listrik masih dibutuhkan Indonesia sampai masa yang akan datang. Pulau Kalimantan adalah salah satu pulau di Indonesia yang memiliki peranan penting dalam perekonomian dan industri, sehingga dibutuhkan pengembangan sistem kelistrikan sesuai dengan kebutuhan beban yang bertambah. Untuk memenuhi daya pada suatu wilayah yang memiliki kekurangan maka dilakukan pengembangan interkoneksi sistem kelistrikan Kalimantan 275 kV dengan jalur transmisi Sei Raya, Ketapang, Sampit, Palangkaraya, Banjarmasin, Balikpapan, Samarinda, Bontang, dan Tanjung Redeb. Dalam proses pengembengan interkoneksi terdapat kendala seperti gangguan sirkuit pendek (short circuit) dan generator lepas yang mempengaruhi kestabilan sistem kelistrikan. Pada penelitian ini dilakukan analisis pada sistem kelistrikan 275kV Kalimantan untuk menentukan kestabilan sistem. Analisis kestabilan sistem dilakukan dengan menentukan pemadaman waktu kritis (Critical Clearing Time) akibat generator lepas dan sirkuit pendek 3 fasa pada saluran Samarinda-Balikpapan. Hasil analisis kestabilan transien akibat sirkuit pendek 3 fasa pada saluran Samarinda-Balikpapan tahun 2022 didapatkan waktu yang bisa dipertahankan kestabilannya yaitu 0,990 detik dan waktu tidak stabil yaitu 0,991 detik. Tahun 2024 didapatkan waktu yang bisa dipertahankan kestabilannya yaitu 0,220 detik dan waktu tidak stabil yaitu 0,221 detik. Sedangkan Tahun 2026 didapatkan waktu yang bisa dipertahankan kestabilannya yaitu 1,720 detik dan waktu tidak stabil yaitu 1,721 detik. Hasil gangguan akibat generator lepas yaitu seluruh sistem dalam keadaan stabil, karena respon sudut rotor, respon frekuensi, dan respon tegangan masih dalam batas standard. =============== Electrical energy is still needed Indonesia until the future. Kalimantan island is one of the islands in Indonesia that has an important role in the economy and industry, so it needs the development of electrical systems in accordance with the needs of increased load. To fulfill the power in an area with deficiency, the development of 275 kV interconnection system of 275 kV electricity system with transmission line of Sei Raya, Ketapang, Sampit, Palangkaraya, Banjarmasin, Balikpapan, Samarinda, Bontang and Tanjung Redeb. In the process of conveying interconnection there are constraints such as short circuit breakdown (short circuit) and freelance generator that affect the stability of electrical system. In this research, an analysis of 275kV Kalimantan's electrical system is used to determine the stability of the system. System stability analysis is performed by determining Critical Clearing Time due to freelance generator and 3 phase short circuit on Samarinda-Balikpapan channel. The result of transient stability analysis due to short circuit of 3 phase on Samarinda-Balikpapan channel in 2022 found time that can be maintained its stability is 0,990 seconds and time unstable is 0,991 second. Year 2024 obtained a time that can be maintained stability is 0,220 seconds and unstable time is 0,221 seconds. While Year 2026 obtained time that can be maintained stability is 1.720 seconds and time is not stable that is 1.721 seconds. The result of the disruption caused by the loose generator is that the whole system is stable, because the rotor angle response, the frequency response, and the voltage response are still within the standard range.
