AVRs and PSSs revisited

2015 9th International Conference on Electrical and Electronics Engineering (ELECO), 2015
In this paper a conceptual analysis on the effect of Automatic Voltage Regulators (AVR) and Power System Stabilizers (PSS) for small signal stability (SSS) of power systems is developed. A modal formulation approach including the use of the Participation Matrix is used. The Modal Formulation is performed considering synchronous generator (SG) equations
