Simulation of a Power Transformer Differential Protective Relay [PDF]

open access: yesEngineering and Technology Journal, 2009
The aim of this work is to simulate a differential relay, which ensures security for external fault, inrush, and overexcitation conditions and provides dependability for internal faults, to protect a single phase power transformer.

Transformer EMF in differential equations of synchronous generators [PDF]

open access: yesE3S Web of Conferences, 2019
The article presents differential equations of a synchronous generator transformed according to the theory of two reactions, that is, in the axes d-q. We consider the influence of transformer EMF on transients.

Transient Stability Improvement of the Power Systems

open access: yesIndonesian Journal of Electrical Engineering and Computer Science, 2018
<p>During the last few decades, electrical power demand enlarged significantly whereas power production and transmission expansions has been brutally restricted as a result of restricted resources as well as ecological constrains. Consequently, many transmission lines have been profoundly loading so the stability of power system became as ...

Tower Models for Power Systems Transients: A Review

open access: yesEnergies, 2022
Fast-front transients play an important role in the insulation design of any power system. When a stroke hits the shield wire or the tower of high-voltage overhead power lines, flashover may occur either along the span or across tower insulators, depending on the relevant voltages and insulation strength.

Deep-Learning Based Fault Events Analysis in Power Systems

open access: yes, 2022
The identification of fault types and their locations is crucial for power system protection/operation when a fault occurs in the lines. In general, this involves a human-in-the-loop analysis to capture the transient voltage and current signals using a ...
