Modeling and Link Performance Analysis of Busbar Distribution Systems for Narrowband PLC [PDF]

Radioengineering, 2017
Busbar distribution system is used as a modular infrastructure to carry electrical energy in low voltage grid. Due to the widespread usage in industrial areas, the power line communication possibilities should be investigated in terms of smart grid ...

Lightweight BIM modeling and digital twin application for precision maintenance of vertically layered GIS busbar tubes [PDF]

AIP Advances
With the scaling up of power systems toward high voltage and large capacity, gas-insulated switchgear (GIS) with a phase-separated vertical stacking layout has become the preferred choice for urban and compact substations due to its high space ...

Fast Algorithms For Josephson Junction Arrays : Bus--bars and Defects [PDF]

, 1995
We critically review the fast algorithms for the numerical study of two--dimensional Josephson junction arrays and develop the analogy of such systems with electrostatics.

Floppy modes and the free energy: Rigidity and connectivity percolation on Bethe Lattices

, 1998
We show that negative of the number of floppy modes behaves as a free energy for both connectivity and rigidity percolation, and we illustrate this result using Bethe lattices.

Pseudo-loadflow formulation as a starting process for the Newton Raphson [PDF]

, 2010
This paper introduces new models which approximate the AC loadflow problem, but are able to converge (using the Newton Raphson algorithm) from a wider range of starting points.

New principle of busbar protection based on a fundamental frequency polarity comparison.

PLoS ONE, 2019
To overcome the contradiction between speed and reliability in existing busbar protection schemes, a new busbar protection algorithm based on a polarity comparison of fundamental frequency currents is proposed.
