Improvement of an Oscillatory Stability in a SMIB (HEFFRON ? PHILIPS MODEL) by Using Different Tuning Techniques of Power System Stabilizer

One of the major concern in power system operation is related to damping of low frequency oscillation and small signal instability caused by insufficient synchronizing and damping torque in the system. It can cause generators pull out from synchronism and sometimes it is also reason for blackout The main objective of this paper is to install power system stabilizer (PSS) to achieve desired comparative analysis is explored with incorporation of power system stabilizer AVR, PSS AND AVR, PSS WITH PID AND AVR for damping of low frequency oscillation and small signal stability enhancement of SMIB systems
