Fault Line Selection in Resonant Grounded System Based on IMEn
Advanced Materials Research, 2014When the single phase ground fault occurs in resonant grounded system, there are significant differences in the components of fault phase current between fault line and non-fault line. This feature can be reflected by intrinsic mode entropy (IMEn) of fault current. IMEn is a new signal analysis over multiple oscillation levels.

Application of distributed fault line selection device in digital substation
2010 5th International Conference on Critical Infrastructure (CRIS), 2010At present, the small analog signal transmission is adopted between process level and bay level in most of the digital substation systems below 35kV. Considering the characteristic of the structure and the special request for the earth fault line selection device, the design of line selection device is proposed for the digital substations.

Fault Phase Selection Method for Half-Wavelength Transmission Lines
2019 IEEE 3rd International Electrical and Energy Conference (CIEEC), 2019In this paper, a novel faulted phase selection scheme is proposed for time delay longitudinal protection and distance protection applied to half-wavelength power transmission lines. The authors describe the principle of a faulted phase selection scheme for half-wavelength power transmission lines using the fault superimposed voltage and current sampled

A novel fault line selection method of resonant grounding system
2017 IEEE Conference on Energy Internet and Energy System Integration (EI2), 2017In order to solve the problems of fault line selection in resonant grounding system, a novel fault line selection method for distribution network was proposed in this paper. First, continuously measure three-phase voltage and zero-sequence voltage, which detects single-phase ground fault.

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 ...

Fault phase selection for transmission line based on correlation coefficient
2010 International Conference on Computer Application and System Modeling (ICCASM 2010), 2010A novel approach of fault detection and fault phase selection based on correlation coefficient for transmission line is presented in the paper. Our main object in this work is to calculate and analyze the feature space relativity in current of different fault types with the same structure and parameters in each relaying location.
