Abstract

In the suggested paper a different system devices for improving power system stability are examined and compared. A power system stabilizer for synchronous generator (PSS) and adaptive static var compensator (ASVC) are used. Using the conventional PSS tend to vastly improving of power system stability due to interpolation additional components of damping torque, which compensate phase lag of automatic voltage regulator, exciter and generator. The controlling system of ASVC is identify in real time on the basis of estimated parameters and variables of identification model and after that is create a controlling signal which control system device. Thanks to these controls the power system damping is largely increased, like all transient processes performances are improved.
