Abstract

Fenomena feroresonansi merupakan sebuah fenomena transien yang terjadi diakibatkan adanya sebuah hubungan antara induktor non-linear yaitu dari inti besi transformator dengan kapasitor yang terdapat pada saluran transmisi. Fenomena feroresonansi dapat terjadi karena adanya gangguan dari switching. Dalam studi ini dilakaukan penambahan impedansi pada kumparan transformator daya terhadap feroresonansi yang terjadi akibat gangguan switching yang dimodelkan pada perangkat lunak ATP Draw. Hasil dari simulasi menunjukkan dengan penambahan kapasitor shunt dengan rentang 40 – 80 nF, kapasitor sekunder dengan rentang 3 – 5 MVAR serta resistive load bank dengan rentang 0.3 – 1 MW dapat memitigasi fenomena feroresonansi. ======================================================================================================================== Ferroresonance phenomenon is a transient phenomenon that occurs due to a relationship between non-linear inductor that is from iron core transformer with a capacitor that is from transmission line. The phenomenon of ferroresonance can occur due to interference from switching. In this study to determine the impact of the addition of impedance on the power transformer coil to the ferroresonance caused by switching distrubance modeled on the ATP Draw software. The results of the simulation shows that with the addition of impedance that consist of shunt capacitor with range 40 - 80 nF, secondary capacitor with range 3 - 5 MVAR and resistive load bank with range 0.3 - 1 MW can mitigate ferroresonance phenomenon.
