Abstract

This study presents a new method for locating voltage sag sources in power distribution networks. The proposed method estimates the voltages at the unmonitored buses by using the regression coefficients. First some bus voltages were monitored using power quality recorders in the power distribution system. Then, the voltage deviation index and the standard deviation index, represent the deviation of bus voltages before and after a disturbance were utilized to determine the voltage sag source location. To validate the proposed method, the IEEE 9 bus test system was used. The test results showed that the proposed method was accurate in determining the location of voltage sag sources in the test system.
