Abstract

This paper presents a new intelligent numerical algorithm for analysis of transmission lines disturbance records. The algorithm improves the existing methodologies for fault location, adaptive autoreclosure, detailed disturbance records analysis, and fault data management. It is based on the processing of voltages and currents recorded at both of the line terminals. The algorithm does not require synchronized sampling of data from the line terminals. The proposed algorithm is derived in the spectral domain and is based on the application of the discrete Fourier transform. In the algorithm development, the fault arc is included in the complete fault model. One of advanced algorithm features is ability to determine both the arc and the fault/tower-footing resistance. The algorithm is thoroughly tested using EMTP simulation and real data records.
