Influence of Sensor Feedback Limitations on Power Oscillation Damping and Transient Stability

چکیده
Fundamental sensor feedback limitations for improving rotor angle stability using local frequency or phase measurement are derived. Using a two-machine power system model, it is shown that improved damping of inter-area oscillations must come at the cost reduced transient margins, regardless control design method. The stem from excitation an mode by external disturbances cannot be estimated with certainty information. results validated on modified Kundur four-machine two-area test where active modulated embedded high-voltage dc link. Damping measurements, unavoidably leads to increased deviation following certain load disturbances. For highly stressed system, this may lead instability. derived in paper motivate need wide-area measurements oscillation control.
