MARTINEZ GARCIA, Antonio A.; VILARAGUT LLANES, Miriam; TORRES BREFFE, Orlys E.  y  PEREZ MARTINEZ, Maykop. Setting of Power System Stabilizers based in PSAT free package calculations. Energética [online]. 2015, vol.36, n.1, pp. 83-93. ISSN 1815-5901.

Normally, voltage regulation is the primary mode of control, which improves voltage and transient stability. The introduction of generator´s fast voltage regulators improves Electrical Power Systems ability to generate synchronizing torque to maintain stability. These control devices have a negative effect in damping system oscillations. Supplementary control in generator's voltage regulators (PSS) is the most economic solution to improve system damping. This supplementary control is obtained using power system dampers. PSAT abilities are used in order to obtain setting of this supplementary control in a simple longitudinal two areas system, similar to Cuban Electric Power System.

Palabras clave : power system stabilizers; small signal oscillations; PSAT; PSS.
