| description | In this paper, a new fault locator scheme is introduced to address the non-homogeneity of combined transmission lines (Taba-Aqaba Intertie transmission system). To achieve this goal, the faulted side is first determined using a new algorithm for identifying faulted segments. This identification algorithm relies on the voltage’s rate of change along the nonhomogeneous lines in the pure positive-sequence circuit, exploiting the inequality of positive-sequence impedances between power cables and overhead lines. The number of outputs generated by the algorithm is one less than the number of line segments being analyzed. For systems with two segments, the output directly identifies the faulted segment. However, for combined lines with three segments, a new voting system is utilized to determine the faulted segment. The fault distance is then calculated based on the identified faulted segment. To evaluate the proposed scheme, various fault scenarios are simulated on the Taba-Aqaba Intertie transmission system, which connects the Egyptian and Jordanian networks, using ATP-EMTP. These tests encompass different fault types and locations, including cases near the interconnection points between the segments. Additionally, the scheme is tested under nonlinear faults. |
