An Adaptive PMU-Based Wide Area Backup Protection Scheme for Power Transmission Lines

Mohsen Kalantar Neyestanaki

This paper proposes a novel adaptive wide area backup protection scheme for transmission lines. In the proposed scheme, both the faulted line and fault location are determined by a limited number of synchronized phasor measurements. Based on phasor measure ...

Use of the full-wave Finite Element Method for the numerical electromagnetic analysis of LEMP and its coupling to overhead lines

Mario Paolone, Carlo Alberto Nucci

The computation of lightning-originated surges on overhead power lines due to nearby lightning return strokes requires accurate models for the calculation of both the incident lightning electromagnetic pulse (LEMP) and the coupling of this field to the lin ...

Effects of nearby buildings on lightning induced voltages on overhead power distribution lines

Mario Paolone, Carlo Alberto Nucci

For the case of urban overhead lines, the presence of nearby buildings is expected to affect the overvoltages induced by nearby cloud-to-ground lightning return strokes. So far, this effect has been seldom taken into account in the literature on the subjec ...

A Review of Field-to-Transmission Line Coupling Models With Special Emphasis to Lightning-Induced Voltages on Overhead Lines

We discuss the transmission line (TL) theory and its application to the problem of lightning electromagnetic field coupling to TLs. We start with the derivation of the general field-to-TL coupling equations for the case of a single-wire line above a perfec ...

A new method to locate faults in power networks based on electromagnetic time reversal

Mario Paolone, Reza Razzaghi, Gaspard Lugrin, Hossein Mahmoudimanesh

The paper presents a new method based on the Electromagnetic Time-Reversal (EMTR) for locating faults in power systems. The applicability of the EMTR to electromagnetic transients associated with traveling waves in transmission lines originated by the faul ...
