Investigation of Parameters on Small Signal Stability of 206.1 MVA Generators
Waluyo , Gregorius Grady Krisshandy and Nandang Taryana

Abstract: This research was investigation on small signal stability on two generators. The analyses were based on the single machine infinite bus with the increasing load as 25% of 175 MW and 85 MVAR. It was yielded the damping ratios, oscillating frequencies and stability conditions. Furthermore, it could be calculated the system synchronizing and damping constants. The results for the active and reactive powers and for the terminal and bus voltages in both generators were the same as the oscillating in 8-9.3 sec. The chosen data for the computations were at the time before the increasing load in 7.8 sec with every sampling oscillation as 0.05 sec. The results were the system in asymptote stables with the 0.0043-0.0044 damping ratios, 1.2108-1.2132 Hz for oscillating frequencies, around 1.47 pu torque for synchronizing constant and 0.50 pu torque per changing speed for the damping constant
