Dholakiya  \n-Devendra P. Parmar  \nAbstract  \nThe extensive interconnection of power networks by weak tie-lines can restrict the steady-state power transfer limits due to low frequency electromechanical oscillations. The low frequency oscillations may result in interruptions in energy supply due to loss of synchronism among the system generators and a􀀋ect operational system economics and security. Further, in order to maintain steady state and transient stability of synchronous generators, high performance excitation systems are essential. The static exciters with thyristor controllers are generally used for both hydraulic and thermal units. Such exciters are characterized by high initial response and increased reliability due to advances in thyristor controllers and hence have become one of the major problems in the power system stability area. As a solution to this, the generators are equipped with Power System Stabilizers(PSSs) that provide supplementary feedback stabilizing signals which is added to the Automatic Voltage Regulator (AVR) . PSSs augment the power system stability limit and extend the power transfer capability by enhancing the system damping of low","cbCaieUFIpvAhjd0","https://ap.wps.com/l/cbCaieUFIpvAhjd0","pdf",6415907,68,"English","# Abstract\n# List of Figures\n## Classification of Power System Stability\n## Phasor Representation of Electrical Torque\n## Synchronizing & Damping Torque Stability Analysis\n## Hafron-Phillips Model of Excitation System\n## Linearized SMIB Model\n## Block Diagram of Linearized SMIB Model\n## Eigenvalue Loci for Variation in AVR Gain\n## Basic Arrangement of PSS\n## Hafron-Phillips Model of Excitation System with PSS\n## Operating Principle of PSS\n## General Structure of PSS\n## SMIB Model in MATLAB/SIMULINK","[{\"question\":\"Why are Power System Stabilizers needed in interconnected power networks?\",\"answer\":\"Weak tie-lines can trigger low-frequency electromechanical oscillations that threaten synchronism and steady-state transfer capability.
