Exact Expressions for Lightning Electromagnetic Fields: Application to the Rusck Field-To-Transmission Line Coupling Model
Marcos Rubinstein, Farhad Rachidi-Haeri
An exact analytical expression for the electric field of the return stroke as excited by a propagating step current source is derived in this paper. This expression could be advantageously used to evaluate the disturbances caused by lightning on overhead l ...
2023Tower-foot grounding model for EMT programs based on transmission line theory and Marti's model
This paper proposes a tower-foot grounding system model compatible with EMT programs which might be useful for the simulation of lightning transients in overhead lines. The proposed model is based on the solution of the telegrapher's equations and the appl ...
ELSEVIER SCIENCE SA2023A Lightweight Device for Energy Harvesting from Power Lines with a Fixed-Wing UAV
Dario Floreano, William John Stewart
Modern UAVs (Unmanned Aerial Vehicles) suffer from restrictions in flight range and time due to battery capacity limitations. One way to overcome these limitations is to harvest energy from overhead power lines. A growing body of scientific literature has ...
IEEE2022An Efficient Methodology for the Evaluation of the Lightning Performance of Overhead Lines
This article proposes a method for the derivation of a formula that links the maximum lightning-induced-overvoltage occurring on an overhead distribution line with the variables that characterize the lightning return stroke, such as the peak current, front ...
2021Field-to-Transmission Line Coupling Models With Special Attention to the Cooray–Rubinstein Approximation
There are three equivalent procedures to evaluate the voltages induced by lightning on power lines, namely, the Agrawal–Price–Gurbaxani model, the Taylor–Satterwhite–Harrison model, and the Rachidi model. The Cooray–Rubinstein approximation is a procedure ...
2021Lightning-Induced Voltages on Overhead Distribution Lines Computed through Analytical Expressions for the Electromagnetic Fields
Marcos Rubinstein, Farhad Rachidi-Haeri
The evaluation of lightning ElectroMagnetic (EM) fields represents the most cumbersome part of the lightning-induced voltages computation process. Their evaluation is usually performed through a numerical routine or with simplified analytical expressions, ...

Giancarlo Ferrari Trecate, Michele Tucci
We propose a decentralized control synthesis procedure for stabilizing voltage and frequency in AC Islanded microGrids (ImGs) composed of Distributed Generation Units (DGUs) and loads interconnected through power lines. The presented approach enables Plug- ...
PERGAMON-ELSEVIER SCIENCE LTD2020Estimation of the expected annual number of flashovers in power distribution lines due to negative and positive lightning
The paper deals with the estimation of the expected annual number of flashovers in overhead power distribution lines due to indirect lightning strokes and aims at extending a procedure previously proposed by the authors, limited to negative downward events ...
2019A Full-Scale Experimental Validation of Electromagnetic Time Reversal Applied to Locate Disturbances in Overhead Power Distribution Lines
Mario Paolone, Marcos Rubinstein, Farhad Rachidi-Haeri, Zhaoyang Wang, Reza Razzaghi
Electromagnetic time reversal (EMTR) has emerged as a promising technique to locate disturbances in power grids, thanks to its location accuracy and robustness against parameters uncertainties. Furthermore, in a reflective medium, like the one of a power n ...
2018On Non-Uniform Transient Electromagnetic Field Coupling to Overhead Transmission Lines
Transient electromagnetic fields can couple to overhead power transmission and distribution lines, causing damage to the connected equipment. In real cases, incident electromagnetic fields exhibit different spatial and temporal waveform distributions along ...
