SIMULATION AND CALCULATION OF REACTOR CONSIDERING THE EFFECTS OF MAGNETIC SATURATION

Abstract

A reactor is an inductive element commonly used to limit short-circuit
currents and maintain rated voltage during grid faults. Additionally, reactors,
when combined with capacitors, have the ability to filter harmonic waves in
the distribution network. When selecting a reactor, the most important
parameter is the inductance value. Traditional analytical formulas can be used
to calculate the inductance value. However, with the advancement of
computing technology, inductance can now be computed using numerical
methods, particularly the finite element method. Therefore, this study utilizes
software applying the finite element method to calculate the inductance of an
available reactor on the market. Furthermore, the paper also considers the
saturation phenomenon and its impact on the inductance value of the reactor.
