A novel fault features extraction scheme for power transmission line fault diagnosis
IEEE Africon '11, 2011This paper proposes a novel transmission line fault detection and classification scheme, based on a single-end measurements using time shift invariant property of a sinusoidal waveform. Various types of faults at different locations, fault resistance and fault inception angles on a 400 kV – 361.65 km power system transmission line are investigated. The

Six-phase (multi-phase) power transmission systems: Fault analysis
IEEE Transactions on Power Apparatus and Systems, 1977The motivation for writing this paper stems from the question, "If the concept of six- (multi-) phase systems become feasible, how to plan such systems?" One of the important aspects of transmission planning is the design of adequate protective scheme which requires a detailed fault analysis.

Faulted Phase Selection for Half-Wavelength Power Transmission Lines
2018 IEEE Power & Energy Society General Meeting (PESGM), 2018In this work, a novel faulted phase selection algorithm is proposed to be used for distance protection applied to half-wavelength power transmission lines. These lines represent an alternating current solution for very-long point-to-point interconnections as an alternative to HVDC.

Active Power Enhancement Control Strategy of Grid-Forming Inverters Under Asymmetrical Grid Faults
IEEE transactions on power electronicsDue to the simple implementation and good dynamic response, the current-limiting gain control strategy (CLGCS) is widely utilized to limit the overcurrent of grid-forming inverters under asymmetrical grid faults. However, it will curtail the transmission

Incremental Power Improves Relay Selectivity to Transmission Line Faults
Journal of The Institution of Engineers (India): Series B, 2018A research work published in 2014 reported a novel relaying principle for protection of transmission lines using signum function of instantaneous power flows at the two ends of the line. Subsequently, a detailed study of this relaying principle to evaluate its selectivity (sensitivity to detect all internal faults and stability on external faults and ...

Neural network approach to power transmission line fault classification
Proceedings of ICICS, 1997 International Conference on Information, Communications and Signal Processing. Theme: Trends in Information Systems Engineering and Wireless Multimedia Communications (Cat. No.97TH8237), 2002This paper presents a new solution to fault classification of high voltage transmission lines and shows its effectiveness in digital simulation on a realistic 500 kV power system. The scheme is based on backpropagation and Kohonen neural networks and a comparison between them is made.
