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 was designed, SMIB used PSS before optimization and SMIB used PSS after optimization of BA to see the frequency response and rotor angle. The simulation results show that the frequency response due to changes in load is 0.01 p.u, 0.03 p.u and 0.05 p.u overall. The simulation results show a very good reduction in the value of overshoot and settling time shown in PSS after optimization using BA with damping ratio > 5% which is able to reduce 62.8% at a change in load of 0.01 p.u, 62.98% at a change in load of 0.03 p.u and 62.95% at a change in load of 0.05 p.u.
