Overhead power line design : What restricts a power line?

open access: yes, 2020
This report contains the influencing factors in high voltage overhead power lines and how these factors are controlled and calculated. A program has been produced so that a projector easily can insert the overhead line supports’ and lines’ parameters in ...

A theoretical model of rain–wind–induced in-plane galloping on overhead transmission tower-lines system

open access: yesAdvances in Mechanical Engineering, 2015
Rain–wind–induced galloping phenomenon often occurs on overhead transmission tower-lines system, just as icing galloping and vortex-excited vibration; this kind of instability oscillation can cause power-line breakage or tower failure.

Robust design optimization for overhead power transmission line design [PDF]

open access: yesQuy Nhon University Journal of Science
Most practical design methods for overhead power transmission lines primarily rely on empirical formulas. This paper proposes a robust design–based two-stage optimization framework for overhead power transmission line design.

A 3D Laboratory Test-Platform for Overhead Power Line Inspection

open access: yesInternational Journal of Advanced Robotic Systems, 2016
Using unmanned aerial vehicles (UAVs) for performing automatic inspection of overhead power lines instead of foot patrols is an attractive option, since doing so is safer and have considerable cost savings, among other advantages.

Ensuring the Continuity of Power Supply to the On-Board Auxiliary Devices of the Trolleybus through the Recuperation of Kinetic Energy

open access: yesEnergies, 2021
When a trolleybus travels through insulated sections of the overhead contact line, it experiences momentary power interruptions, which adversely affect the vehicle’s on-board auxiliary subassemblies.

Behavioral modeling of power line communication channels for automotive applications [PDF]

open access: yes, 2012
The black-box modeling of a power line communication channel in a car is addressed in this paper. The proposed behavioral approach is based on the so-called multipath model representation, that describes the transmission of a signal on a possibly complex

Security‐constrained active power curtailment considering line temperature and thermal inertia

open access: yesIET Generation, Transmission & Distribution, 2023
A novel method is introduced to determine cost‐optimized active power curtailment (APC) of renewable energy sources (RES) considering weather‐dependent dynamic line rating (DLR).
