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 ...
2023A 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 ...
IEEE2022Simulation of High-Frequency Transients in Overhead Lines Including Frequency-Dependent Soil Parameters: an FDTD Aproach
Farhad Rachidi-Haeri, Rafael Silva Alipio
This paper investigates the effect of frequency-dependent soil parameters on the simulation of electromagnetic transients on overhead lines, based on the application of the FDTD method to solve the telegrapher’s equations. The ground return impedance is ca ...
2021A Data-Driven Fault Location Algorithm Based on the Electromagnetic Time Reversal in Mismatched Media
Mario Paolone, Zhaoyang Wang, Zhe Chen
The classical electromagnetic time reversal (EMTR) fault location method in power systems can be time consuming, especially when a high location accuracy is desired. To cope with this issue, the concept of EMTR in mismatched media has recently been introdu ...
2021Time reversal applied to fault location in power networks: Pilot test results and analyses
Mario Paolone, Zhaoyang Wang, Reza Razzaghi
This paper presents the results of a pilot test performed on a real medium voltage distribution network in Switzerland with the aim of assessing the performance of a fault location system relying on the Electromagnetic Time Reversal (EMTR) method. To the b ...
2020Electromagnetic Time Reversal: Theory, Application to Fault Location in Power Networks and Experimental Validation
The time-reversal invariance is readily described and universally embodied in most laws of nature, either in a strict or in a soft sense. Based on this underlying physical principle, time-reversal theory has been theoretically and experimentally studied in ...
EPFL2020A scalable, line-independent control design algorithm for voltage and frequency stabilization in AC islanded microgrids
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 LTD2020Four Quadrant Bus-Tie Switch for Protection of Shipboard Power Systems
The desire to increase the voltage of DC shipboard power distribution networks to the medium voltage level derives from the pressure to reduce the operating costs of such systems by increasing their efficiency. Solid state bus-tie switches are accepted to ...

IEEE2020Electromagnetic Time Reversal Similarity Characteristics and its Application to Locating Faults in Power Networks
Mario Paolone, Farhad Rachidi-Haeri, Zhaoyang Wang, Reza Razzaghi
The existing Electromagnetic Time Reversal (EMTR)-based fault location methods generally leverage the features of the signals simulated in the EMTR reversed-time stage (relative to the direct-time stage wherein a fault occurs and its originated transient s ...
