摘要：This aim of this paper was to obtain a design of fuzzy logic to replace the Derivative Integral Proportional Power System Stabilizer control at excitation system. Stability study correctly and continuously very needed to analyze of system so that can operate by effectively. To learn the dynamic stability that is generator stability experiencing load changing,hence used modeling to components like synchronize generator,transmission line,and load which derived from mathematical equations represent dynamic behavior of electric power system. Derivation of mathematical equations represent dynamic behavior of system can elaborated by using equation of differential of linear and effect that happened which is in the form of low frequency oscillation can be re-stabilized by enhancing the addition control signal. The addition of control signal done by enhancing PSS block in the form washout block and lead compensator with the input in the form of change of rotor speed,change offrequency or changeofpower acceleration. The effort to improve the lead compensator in this time using the control of compensator PID (Derivative Integral Proportional). The control of PID can improve the transient response and eliminate error of steady state. But on the other side,PID also have the weakness that is jump incidence which big relative cmd time of achievement steady state which old relative. Based on the weakness,in this article will try to design the fuzzy logic control system to replace the PID control expected can overcome the weakness of PID control.
