【 摘 要 】
The main aim of this paper is damping power system oscillations, which has been accepted as one of the major concerns in power system operation. In the recent past Power System Stabilizer (PSS) was used to damp Low frequency Oscillations. At present FACTs devices, such as static synchronous series compensator (SSSC) is welldesigned to enhance the transient stability of the power system and to damp LFO. In this research a modified Heffron- Phillips model of a single machine infinite bus (SMIB) system installed with SSSC is used. In order to evaluate the performance of the proposed hybrid Fuzzy damping controller in damping LFO, the SMIB power system is subjected to a disturbance such as changes in mechanical power. The complete digital simulations are performed in the MATLAB/Simulink environment to provide comprehensive understanding of the issue. Simulation results demonstrate that the developed Hybrid Fuzzy damping Controller would be more effective in damping electromechanical oscillations in comparison with the conventional fuzzy logic controller and conventional proportional-integral (PI) controller.
