Abstract :
In this paper, a wide area monitoring system (WAMS) for the 420 kV Norwegian bulk transmission grid has been evaluated. The robustness of the PMU measurements has been demonstrated by a direct comparison of phasor information from the PMUs and a state estimator (EMS). The paper highlights benefits of both off-line and on-line WAMS applications: a method for real-time detection of power oscillations, as well as the use of WAMS as input to power system stabilizers (PSS), is presented
