“…In this equivalent circuit, the resistor R models the potential transformer (PT) core losses. The core losses can be modelled by either accurate hysteresis model or a constant linear resistance [28][29][30]. The magnetisation current is modelled by a two-term polynomial, which has been obtained and introduced in [27], and given in (1).…”

This study presents a novel DC reactor-based ferroresonance and fault current limiter (DRFFCL) for stabilising ferroresonance oscillations of potential transformer (PT) in 33 kV distribution network and decreasing the amplitude of the fault current to an acceptable level. At first, the ferroresonance overvoltage is introduced and various types of overvoltage in the PT are studied. Then, the effects of the suggested DRFFCL on these oscillations are investigated. It is shown that the proposed DRFFCL not only can control the ferroresonance oscillations, but also can decrease the fault current amplitude in the case of short-circuit faults occurrence. The DRFFCL performance is simulated using MATLAB software and a scaled-down laboratory prototype is implemented and tested for the simulation results validation. The measured results are in agreement with the simulation results and clearly show the ability of the DRFFCL for controlling both the ferroresonance overvoltage and fault current.

“…Multiple periodic and nonperiodic modes in the system can be initiated by ferroresonance [8]- [11]. Depending on the system parameters and the initial conditions in a ferroresonance circuit, fundamental [3], subharmonic [12], quasi-periodic [13], or chaotic [14] ferroresonance can occur.…”

This paper reports on ferroresonance phenomenon in distribution networks after the islanding of a distributed generation (DG) unit. Five coupling transformer configurations in synchronous machine-based DG are used to analyze and discuss occurrences of ferroresonance. PSCAD/EMTDC software was used to simulate the various configurations to collect data for analysis. Chaos theory was used to analyze the simulation results in a MATLAB environment in order to understand the type of ferroresonance present. This paper supports that synchronous machine-based DG units could be highly prone to occurrence of ferroresonance phenomenon after islanding with differences observed among the five configurations studied. This paper confirms that a groundedwye/delta connection is highly prone to ferroresonance and a delta/grounded-wye connection avoids ferroresonance when a DG unit becomes an island. Résumé-Ce travail de recherche concerne le phénomène de ferrorésonance dans les réseaux de distribution après l'isolation d'une unité de production distribuée (PD). Cinq configurations de transformateurs de couplage de PD basés sur les machines synchrones sont utilisées pour analyser et discuter des occurrences de ferrorésonance. Le logiciel PSCAD/EMTDC a été utilisé pour simuler les différentes configurations pour l'acquisition des donnéespour l'analyse. La théorie du chaos a été utilisée pour analyser les résultats de la simulation avec MATLAB pour mieux comprendre la ferrorésonance en question. Cet article prouve que les unités PD synchrones basées sur les machines synchrones après l'isolation pourraient être sujettes à l'apparition du phénomène de ferrorésonance avec des différences observées entre les cinq configurations étudiées. Ce document confirme que la connexion Wye-Delta liée à la masse peut avoir lieu quand une unité PD est isolée et une connexion delta/masse évite la ferrorésonance quand une DG est isolée aussi.
