A method (400) includes obtaining a voltage phasor (402), a current phasor (404) and a mechanical rotor angle (405) of a source end generator. A receiving end generator impedance and a line impedance between the source end generator and a receiving end generator is also estimated (406). Furthermore, a swing angle between an internal voltage of the source end generator and an internal voltage of the receiving end generator as a function of obtained voltage phasor, current phasor, mechanical rotor angle and the impedances is estimated (408). A power swing condition is then determined (410) based on the estimated swing angle. |
