Abstract
Analisis mengenai kestabilan transien sistem tenaga memegang peranan
penting dalam operasi sistem tenaga listrik. Karena sebuah sistem tenaga
listrik dapat dikatakan handal apabila sistem tersebut mampu melayani
kebutuhan beban secara kontinyu. Pada sistem selalu terjadi perubahan
beban, sehingga dapat mengakibatkan gangguan atau ketidakstabilan
pada sistem tenaga listrik. Bila gangguan tersebut tidak segera diatasi,
maka akan menyebabkan ketidakseimbangan sistem, salah satunya
adalah putaran rotor pada generator yang mengalami percepatan atau
perlambatan sehingga terjadi hilangnya sinkronisasi pada generator.
Untuk mencapai kestabilan setelah adanya gangguan, dibutuhkan suatu
analisa kondisi transien untuk menentukan Critical Clearing Time
(CCT). Metode yang dipakai adalah metode Time Domain Simulation
sebagai pedomannya adalah perubahan dari sudut rotor generator
sewaktu terjadi gangguan dalam sistem. Selain itu diamati juga
mengenai adanya pengaruh damping dalam kestabilan sistem. Hasil dari
simulasi ini menunjukkan bahwa adanya damping didalam sistem
menyebabkan lebih stabil, sehingga nilai CCT antara sistem yang berdamping
dengan sistem yang tidak menggunakan damping memiliki
nilai Critical Clearing Time (CCT) yang lebih besar pada sistem yang
menggunakan damping.

Analysis of transient stability of power systems hold a very important in
the operation of electric power system. Because a power system can be
said to be reliable if the the system is able to serve of the continuous
load. In the system is always happen to change of the load, so can make
instability of the power system. If the problem doesn’t secure, it will lead
to an imbalance of the system, one of which is the rotation of the rotor of
the generator is experiencing acceleration or deceleration resulting in a
loss of synchronization of the generator. To achieve stability after a
disturbance, it takes a transient condition analysis to determine Critical
Clearing Time (CCT). The method used is the method of Time Domain
Simulation with the guidelines is the change of the generator angel
during a disturbance in the system. But it was observed also on the
influence of damping in the stability of the system. The result of these
simulations indicate that the presence of damping in the system load to a
more stable system, so that the CCT values between the system side by
side with a damping system that doesn’t use the CCT has greater value
on a system with damping.
