Kestabilan sudut rotor pada sistem tenaga listrik perlu diperhatikan agar sistem tetap sinkron setelah terjadi gangguan. Ganggun harus dihilangkan seminimnya sampai pada batas pemutusan waktu kritis atau critical clearing time (CCT). Ketika waktu pemutusan melebihi CCT yang terjadi adalah sistem mengalami ketidakstabilan yang dapat memperburuk kondisi sistem. Pada penelitian ini akan menggunakan model jaringan IEEE 9 Bus untuk mencari nilai CCT di saluran 3 dan 5 dengan metode time domain simulation (TDS). CCT terlebih dahulu didapatkan melalui perhitungan. Kemudian sebagai komparasi, simulasi ETAP dengan analisis transien dan simulasi melalui Matlab diterapkan pada penelitian ini. Hasil menunjukkan nilai CCT pada saluran 3 dari hasil perhitungan yaitu 1,25 detik, simulasi ETAP 1,28 detik dan Matlab sebesar 1,13 detik. Pada saluran 5 nilai CCT secara perhitungan yaitu 1,219 detik, simulasi ETAP 1,28 detik, dan Matlab sebesar 1,18 detik. Dari hasil ini, nilai CCT hasil perhitungan mirip dengan simulasi pada ETAP. Sedangkan nilai CCT melalui simulasi ETAP dan Matlab hanya berbeda 0,15 detik pada saluran 3 dan 0,1 detik pada saluran 5Downloads
