Tuning Pss Untuk Meningkatkan Kestabilan Sinyal Kecil
ABSTRAK In the operation of an electric power system one of the most important issues is stability. The imbalance between the mechanical input power and the electrical load power in the system causes the generator rotor speed (system frequency) and voltage to deviate from normal conditions so that it will disrupt the stability of the system. In this research a simulation of SMIB without PSS wa…
