This paper presents a comprehensive review on the proposed methods based on voltage and current values for the location of the source of voltage sags. An alternative method to locate the sag source when just voltage values are available is introduced. The methods are applied to locate the sag source for a set of simulated cases. The simulations are performed using PSCAD/EMTDC on the model of a regional network including transmission and sub-transmission levels. The results are evaluated to analyze the coherence of the methods and point out their strengths and imitations.

Nyckelord: Power quality, voltage sags (dips), source location.
