Voltage flicker phenomenon is one of the main power quality problems in today's power networks. Before any compensation operation for this phenomenon, the location of each flicker sources must be identified and the effect of each of them on the network flicker value must be determined. Also, methods that require least number of monitoring points are more in demand due to the limitations of measuring voltage and current signals of the network, including cost and time consuming. In one of the latest studies in this regard, by introducing a method based on the wavelet transform and the approximate model of the transmission line between monitoring points, the location of all flicker sources are traced using minimum monitoring points. Moreover, the contribution of each flicker source is determined using of direct flicker voltage measurement. In this paper, an attempt has been made to improve the previous method, by modifying the approximate model intended for the transmission line, so that even if there is noise in the network, it can detect the exact location of flicker sources. Then, the effect of each flicker sources on the total amount of flicker of any network busbar is determined using the same monitoring points of the previous section and without the need for direct measurement.
