Abstract The aspects of fault location for incomplete double-circuit transmission lines have been studied in this paper. Firstly, the characteristics of the incomplete lines are analyzed. Since the traditional pseudo root identification method cannot be applied in fault location for incomplete lines, a new pseudo root identification algorithm is presented based on analyzing the existence of pseudo root. This algorithm can effectively identify pseudo roots of both fault branch and non-fault branch. Then, a fault location algorithm for incomplete double-circuit lines based on line segment parameters is proposed. The method combines fault location with fault branch identification, which can be realized within the entire line. The algorithm is featured by each terminal data without synchronization, and immune to the types of fault, fault resistance and other factors. The simulation results have verified the proposed algorithm.

Key words： Incomplete double-circuit transmission lines fault location fault branch phase-mode transformation pseudo root identification
