Abstract :
An alternative detection algorithm, based on the Generalized Likelihood Ratio Test (GLRT), is proposed for the detection of voltage dips in power systems. The proposed method is compared to the classical approaches based on the voltage root mean square. It is shown, by computer simulations, that the GLRT may provide competitive performance, in terms of capability of correctly detecting the dip starting instant.
