A comparison of rotor damping from adaptive and conventional PSS in a multi-machine power system

A comparison between damping available from a conventional power system stabilizer (PSS) and an adaptive controller is made using a transient stability program simulation of a nine-machine power system. A step change to terminal voltage and variable duration bus faults is used for network disturbances to illustrate the added damping available from the adaptive PSS. Simulation results showing the relative damping contributions of the two stabilizers are presented.<
