Description
Summary:This paper presents a methodology for the relative location of voltage sags source based on voltage measurements only. Network faults are the most frequent disturbances in the electrical systems and in turn are the causes that generate most voltage sags. Thus, the proposed algorithm considers only voltage sags by network faults and a minimum of three voltage meters are required. Power quality can be evaluated automatically using the characterising and extracting information from voltage records. The positive sequence voltages are the descriptors used to determine the relative location of the voltage sags causes and the methodology is applied to a simulation where its effectiveness is verified. Matlab was used for validating this methodology, receiving voltage records of simulated voltage sags in ATP-EMTP.
