The Simulation Damping of Power System Oscillation using Phase-Compensator and PID-Controller in Single-Machine Infinite-Bus

The paper present the dynamic oscillation of the electric power system. The
concept of system resilience that functions for machines that move normally and can
return to a stable state after a disturbance occurs. Oscillation of changes in speed and
oscillation changes in the electric power system occur due to disturbances. Disturbance in
electricity causes an electric current that works on the system beyond the nominal
current. The effect of the current disturbance will have an impact on changes in the
current torque parameters that cause prime-over instability when the generator is
operating. This instability will affect the rotor speed and the voltage emitted by the
generator. Dynamic oscillation repair testing by applying phase compensation control
and PID-Controller on the excitation system is done to see the response of speed and
voltage response when the system is experiencing interference. Observation of system
oscillation response using matlab simulation to see system performance. The simulation
results show that dynamic stability improvement with phase compensation method can
reduce oscillation speed and voltage within 6 seconds and the use of PID-controller can
reduce the speed and voltage in 3 seconds. The phase compensation method and PIDcontroller applied to the excitation system can reduce the electric power system
oscillation.
