Abstract
In accordance with one embodiment, a method for detection of power swing for at least a first range of swing angles between an internal voltage (ES) of a source-end generator and an internal voltage (ER) of a receiving-end generator is provided. The method includes obtaining a voltage magnitude (VS) of the source-end generator, and a current magnitude (IS) of the source-end generator. The method further includes estimating a total reactance (X) between the source-end generator and the receiving-end generator, and estimating a first swing angle (θ) between the ES and the ER as a function of the obtained VS, the obtained IS and the estimated X. The method further includes detecting a power swing condition based on the estimated θ.
