Electrical network components catastrophically fail as a result of aberrant system oscillations. Also, consequently leads to saturation in the ferromagnetic core elements. These factors induce distortions in the voltage and current waveforms as well as a large rise in voltage or current. This paper presents the role of distributed generation (DG) in contributing to ferroresonance investigation reduction in the distribution sector. A high ohmic reactor-shunt limiter (HOR-SL) is introduced as a novel technique based on a negative sequence component to mitigate ferroresonance. The proposed HOR-SL reduces the ferroresonance in distribution system (DS) by no more than 10.5 msec. A PSCAD/EMTDC software is used to model the ferroresonance phenomenon. The simulation results strongly show the effectiveness of using the proposed HOR-SL for limiting ferroresonant oscillations and creating stable orbit in the distribution sector. Case studies verified the effectiveness of the proposed technique in mitigating ferroresonance oscillations and keeping the security of the distribution zone.

“…Ferroresonance overvoltage can overheat the transformer core and burst the surge arresters [26]. Ferroresonance limiter is one of the important functions in the power systems protection that can be a power electronic-based device and limits and even eliminates such overvoltage [27][28][29]. e number of circuit elements and costs can be reduced by using an integrated structure of protection and power quality functions.…”

This paper introduces a multifunctional protective system to mitigate more likely threats in power networks. The proposed device can cope with short circuit current, voltage sag, or swell and dangerous overvoltages due to ferroresonance by elaborate switching in its unified structure. The switching is in fact the main key for playing among the functions and altering the structure. Since the switches receive the control system’s commands based on what happens in the network, an intelligent controller has to be designed to interpret four operating modes and activate the correct function. Following the activation command, the structure is customized through switching action and the network is equipped with the corresponding protection function. The proposed scheme by employing minimum components and therefore achieving significant saving in costs can meet all expectations satisfactorily. Moreover, the control system’s performance is examined by a set of numerical simulations in a Matlab/Simulink environment. The obtained results show that the proposed device is feasible and successfully performs all three functions independently.

“…To reach solutions for protection and delay from over current and voltage caused by ferroresonance, it is necessary to recognize the ferroresonance phenomenon quickly (Rezaei, 2017). In a study, the smart solid-state stress suppressor method was investigated to return the ferroresonance stress to its stabilized state (Heidary & Radmanesh, 2018). Yıldırım et al investigated the frequency properties of disturbances in the voltage waveform caused by the ferroresonance phenomenon by Fourier transform (Yildirim et al, 2009).…”

Ferroresonance is an unexpected, continuous, and undesirable event that causes excessive growth and distortion in the voltage and current waveform, whose cause is unknown and suddenly develops in power systems. To take precautions against the ferroresonance phenomenon, it is necessary to be able to predict how the distortions in the ferroresonance voltage will continue. Today, the ferroresonance problem has not been fully solved yet and more scientific studies are still needed. In this study, a new approach of an LSTM network has been developed that predicts the irregular and excessively large-amplitude continuing behavioral disturbances of the phase voltage in a real electrical power network exposed to ferroresonance. As a result of the study, the ferroresonance-voltage continuing in distorted waveform was estimated with an error of 0.0346 according to the Mean Absolute Percent Error (MAPE). The training data used in the study is only about 5% of all predicted ferroresonance voltage data. The successful estimation of 95% of the Ferreroresonance voltage using only about 5%, proves the success of the LSTM model applied with a new approach for the study.
