Abstract
Kestabilan adalah hal yang utama dalam sistem tenaga listrik. Ada banyak penyebab yang mempengaruhi kestabilan yaitu adanya gangguan hubung singkat yang besar seperti hubung singkat tiga fasa. Sistem transmisi Jawa–Madura–Bali (Jamali) merupakan contoh sistem multi mesin (multi machine) dengan banyak generator pembangkit yang saling terhubung dan bersinkronasi, maka kestabilan harus tetap terjaga. Dalam menjaga kestabilan pada sistem transmisi Jamali 500 kV yang bebannya semakin bertambah, PT. PLN (Persero) melakukan penambahan kapasitas pembangkit sekitar 39.1 GW dan penambahan beberapa GITET baru. Pada tugas akhir ini dilakukan analisis kestabilan transien (transien stability) dengan memberikan gangguan hubung singkat (short circuit) 3 fasa pada GITET Krian dan diasumsikan terjadi didekat bus Krian kemudian dilakukan analisis kestabilan transien. GITET Krian dipilih karena merupakan GITET terbaru dan mempunyai beban tertinggi diantara GITET baru lainnya. Dilakukan analisis Load Flow dan kestabilan transien menggunakan software Matlab. Untuk menentukan Critical Clearing Time (CCT) dilakukan dengan menggunakan kombinasi dua metode, yaitu Metode Biseksi (Bisection Method) dan Time Domain Simulation (TDS), dan didapatkan hasil yaitu mempersingkat waktu pencarian CCT secara otomatis dan sistematis dengan nilai yang akurat. =========== Stability is the main thing in electric power systems. There are many causes that affect the stability of the existence of a large short circuit short circuit such as three phase short circuit. The Java-Madura-Bali (Jamali) transmission system is an example of a multi-machine system with multiple generators connected and synchronized, so the stability must be maintained. In maintaining the stability of Jamali 500 kV transmission system whose load is increasing, PT. PLN (Persero) to increase the generating capacity of about 39.1 GW and the addition of several new GITET. In this final project transient stability analysis is done by giving short circuit (short circuit) 3 phase in GITET Krian and assumed happened near by bus of Krian then do transient stability analysis. GITET Krian is selected because it is the latest GITET and has the highest load among other new GITET. Performed Load Flow analysis and transient stability using Matlab software. To determine Critical Clearing Time (CCT) is done by using combination of two methods, namely Bisection Method (Bisection Method) and Time Domain Simulation (TDS). and the results obtained is to shorten the time of search CCT, automatically and systematically with accurate value.
