A New Method for Fault line Selection of Four-Parallel Transmission Lines
2010 Asia-Pacific Power and Energy Engineering Conference, 2010Based on the theory of twelve sequence components, this paper analyzes the single circuit line fault characteristics of four-parallel transmission lines on the same tower. By use of the relationship of different amplitudes and phases between each sequence components, a new method is proposed for fault line selection of four-parallel transmission lines.

Fault Line Selection Method Considering Grounding Fault Angle for Distribution Network
Journal of Northeast Agricultural University (English Edition), 2015Abstract In the distribution network system with its neutral point grounding via arc suppression coil, when single-phase grounding fault occurred near zero-crossing point of the phase voltage, the inaccuracy of the line selection always existed in existing methods.

Fault Line Selection and Location of Distribution Network Based on Fault Recording Data
2020Single-phase grounding fault line selection is a long-standing problem in the distribution network. The identification rate of single-phase grounding fault is further reduced due to a large number of grid-connected distributed power supply, as well as short distribution network lines and many branches.

Attribute selection for fault location recognition in transmission lines
2006 IEEE Power Engineering Society General Meeting, 2006After a severe disturbance due to an insulation failure in a transmission line, the precise fault location is a critical problem for the maintenance crew. In order to avoid further economical and social costs, fault diagnosis has to be performed as soon as possible.

A new principle of fault line selection for distribution
7th International Conference on Developments in Power Systems Protection (DPSP 2001), 2001Fault line selection is important to maintenance and normal operation of power distribution system. If a fault does not disappear for a long time, it could develop into a phase to phase fault. Then the fault line should be found out as quickly as possible and the fault should be removed.

Line Selection in Active Fault Zones and Meizoseismal Areas
2017This chapter discusses the spatial distribution of the Kunlun Mountain, Bengcuo, and Yambajan–Damxung–Gulu seismotectonic zones and explains the relationship between active faults and earthquakes, which can severely damage railway structures. The line selection and engineering properties of the Qinghai–Tibet Railway in high-intensity earthquake zones ...

High-speed faulted-phase selection algorithm for transmission line protection
2013 26th IEEE Canadian Conference on Electrical and Computer Engineering (CCECE), 2013A new faulted-phase selection algorithm for non-unit transmission line protection scheme is presented in this paper. The proposed algorithm employs the current signal from only one phase of three-phase system. A short time window of roughly two milliseconds is used for determining the faulted phase involved in single-phase to ground faults, so the ...

Single-phase grounding fault identification and fault line selection for compensation grid
Proceedings of The 7th International Power Electronics and Motion Control Conference, 2012A new grounding fault line selection method based on small-world network theory is proposed in order to solve the problems existing in grounding fault line selection device of compensation grid, such as that the correct rate of grounding fault line selection is not high and the selection device cannot recognize high-impedance and low-impedance ...

A New Strategy Based on Feature Selection for Fault Classification in Transmission Lines
2016The transmission lines are the element most susceptible to faults on power systems, and the short circuit faults are the worst type of faults than can happen on this element. In order to avoid further problems due to these faults, a fault diagnostic is necessary, and the use of front ends is required.
