The modern power system is large network consisting of various types of interconnected electrical components. The main intention of installing such components is to produce and deliver with optimum efficiency and uninterruptedly. Now along with electrical components their also present fast behaving electronic components like components present in excitation system of alternator. This leads to mechanical & electrical resonances end up with oscillations in the network. This low frequency oscillations or often referred as small signal disturbances is to be reduced in order to get better overall performance. Here the PSS comes into picture which provide addl. signal to VR to damp out this oscillations. Here different design aspects of PSS & AVR has been presented. These design are broadly classified as conventional(CPSS) and non-conventional technique. Although many design approaches are there in conventional techniques here only three out of them is presented. They are Root Locus Technique, Bode Plot Technique, State space techniques. Among non-conventional approaches only ANFIS based controller design is presented here. The conventional approaches uses transfer function model applicable for highly linearized system whereas the non-conventional approach is also applicable for nonlinear systems. In each case the Automatic Voltage Regulator (AVR) and Power System Stabilizer (PSS) design method is presented separately and results are shown separately.
