Application of Traveling-Wave Fault Location in Networks with Complex Topology and Distributed Generation

The report presents the adaptation and practical implementation of a wave-based method for fault location in distribution power grids characterized by complex topology, the presence of extended branches, cable inserts, and Renewable Energy Sources (RES). The work substantiates the advantage of wave methods over classical impedance-based approaches under conditions of fluctuating and asymmetrical loads, multiple power supply points, and frequent changes in power flow direction. The wave method does not require precise knowledge of the line's specific electrical parameters and maintains high accuracy regardless of the line length and its operating mode, making it particularly relevant for modern active distribution power grids.
