Abstract

Analisis kestabilan transien adalah sebuah studi yang diperlukan saat melakukan perencanaan pembangunan atau pengembangan sistem kelistrikan. Kestabilan transien adalah kemampuan suatu sistem untuk mempertahankan sinkronisasinya saat terkena gangguan transien, yang salah satunya adalah gangguan hubung singkat. Sesuai dengan Rencana Usaha Penyediaan Tenaga Listrik (RUPTL), untuk meningkatkan rasio elektrifikasi di Indonesia, maka dilakukan pengembangan sistem kelistrikan untuk meningkatkan penyediaan tenaga listrik. Pulau Kalimantan memiliki sistem kelistrikan yang belum terinterkoneksi, sehingga dilakukan perencanaan pembangunan sistem transmisi 500 kV HVAC untuk melakukan interkoneksi sistem kelistrikan, serta memanfaatkan teknologi sistem transmisi 500 kV HVDC. Pada penelitian ini dilakukan analisis kestabilan transien pada sistem kelistrikan Kalimantan dengan backbone sistem transmisi 500 kV HVAC dan 500 kV HVDC menggunakan time domain simulation dengan kasus 3-phase short circuit pada sistem transmisi HVAC dan HVDC Short Circuit pada sistem transmisi HVDC. Hasil dari simulasi yang dilakukan, frekuensi terbesar yang didapatkan yaitu 102.87% dan frekuensi terendah yaitu 95%, keduanya masih dalam batas toleransi. Hasil menunjukkan bahwa sistem kelistrikan Kalimantan dengan backbone 500 kV yang telah dimodelkan mampu mempertahankan kondisi sinkronnya ketika terjadi gangguan pada kasus yang diberikan. ================ Transient stability analysis is an indispensable study when undertaking a new electrical system development plan or planning for the development of an existing electrical system. Transient stability is the ability of a system to maintain its synchronization when transient disturbances occurs, one of transient disturbance is short circuit. In accordance of Rencana Usaha Penyediaan Tenaga Listrik (RUPTL), to increase electrification ratio in Indonesia, is by developing electrical system to increase electricity supply. Kalimantan has electrical system that is not interconnected yet, so it is planned to build a 500 kV AC transmission system to interconnect the existing electricity system in Kalimantan, and utilize the technology of 500 kV HVDC transmission system. In this final project, transient stability analysis is applied on Kalimantan electrical system with 500 kV AC transmission system backbone and 500 kV HVDC transmission system using time domain simulation with 3-phase short circuit case on AC transmission system and HVDC Short Circuit on HVDC transmission system. The results shown that the largest frequency of the system is 102.87% and the lowest frequency is 95%, which is both are still within the limits of tolerance. The results show that Kalimantan electrical system with 500 kV backbone that has been modelled is able to maintain its synchronous condition when it interference with the cases occurs.
