Experimental Analysis of a Multi-conductor Uniform Line above Soil for Modelling a Railway Line

Travelling-wave Modelling of Uniform Multi- Conductor Transmission Line Networks — Part Ii: Experimental Validation — Applica- Bility

In Part I of this work, travelling-wave modelling of uniform multi-conductor transmission line networks was analytically established with direct applicability to narrowband transmission, covering any network formed of lossy (in the general case), diagonalisable uniform multi-conductor transmission lines of either distinct or degenerate eigenvalues. As the whole work applies especially in the fi...

Travelling-wave Modelling of Uniform Multi- Conductor Transmission Line Networks — Part I: Analytical Derivation

In Part I of this work, analysis of uniform multi-conductor transmission line networks is performed on travelling-wave basis, via “quasi-TEM” approach. Narrowband interpretation of the modal theory in the time domain and quantification of the multiple reflections effect are both included. Theoretical demonstration and analytical formulation are provided, along with guidelines towards computatio...

Analysis of Aeolian Vibrations of Transmission Line Conductors and Extraction of Damper Optimal Placement with a Comprehensive Methodology

Energy balance method is an effective and simple method which is used in the amplitude calculation of Aeolian vibration in transmission lines with Stockbridge damper. However, the accuracy of the results obtained by this method, heavily depends on the assumed mode shapes of the conductor vibration. In this study, by considering an appropriate model for the conductor vibration, a comprehensive m...

Application of Intelligent Water Drops in Transient Analysis of Single Conductor Overhead Lines Terminated to Grid-Grounded Arrester under Direct Lightning Strikes

In this paper, Intelligent water drop algorithm (IWD) is used to analyze single overhead line connected to grid-grounded arrester. In this approach, at first Norton’s equivalent circuit of the overhead line over lossy soil is computed by method of moments (MoM) and then for the problem under consideration, a nonlinear equivalent circuit in the frequency domain is proposed. Finally applying inte...
