A New PMU-Based Fault Location Algorithm for Three-Terminal
Existing two-terminal fault location method can not be directly applied to the three-terminal transmission lines, this paper presents a new PMU-based fault location algorithm for three-terminal transmission lines. The development of the algorithm takes advantage of PMU measurement data synchronization, uses distributed parameter line model, first of all judging the fault zone after a failure, uses Thevenin's Theorem to merge the non-slip fault, so the three-terminal system is simplified the two-terminal system, Then we can use the two-terminal fault location principle of fault location. Through MATLAB simulation shows the correctness of the algorithm.
