Summary, in English

Phasor measurement signals are used as only input to a wide-area power system stabilizer to increase interarea mode damping of the Icelandic system. Modal analysis and time simulations of a detailed model show that frequency difference as PSS input gives a damping improvement that is robust to drastic changes in system topology. Field data from phasor measurement units indicate high signal quality and that frequency difference is realistic as PSS input. The wide-area PSS is compared against a generic local PSS with shaft speed input. The total performance is comparable, but while the local PSS has better local mode damping, frequency difference appears to give better interarea mode observability. Continued work aims at combining these advantages in a PSS that uses both local and wide-area signals
