Abstract

Peran CVT dalam sistem kelistrikan sangat vital, terutama untuk sistem pengaman dan pengukuran. Akan tetapi rangkaian pada CVT dapat menimbulkan feroresonansi. Fenomena ini dapat menyebabkan tegangan lebih dan arus lebih pada CVT. Dalam studi ini dilakukan mitigasi feroresonansi dengan FSC pasif. Perangkat lunak yang digunakan pada studi ini adalah ATP/EMTP. Parameter FSC pasif diteliti untuk mendapatkan nilai yang tepat. Dari hasil simulasi didapatkan nilai Rr = 12 Ohm dan Rn = 1000 Ohm pada FSC pasif. Selanjutnya FSC pasif diuji dengan perubahan beban CVT. Beban R dan L divarasi untuk mendapatkan perbandingan nilai tegangan dan arus sebelum serta sesudah dipasang FSC pasif. Dari hasil simulasi diperoleh kinerja dari FSC pasif dapat memitigasi feroresonansi dengan baik untuk setiap nilai beban yang diuji =============================================================================================== The role of Capacitive Voltage Transformer (CVT) in the power system is vital, especially for protection system and measuring. But the circuits in the CVT can cause a ferroresonance. This phenomenon leads to overvoltage and overcurrent in CVT. This paper presents a study of ferroresonance mitigation using passive Ferroresonance Suppression Circuit (FSC). The software that being used in the study is ATP/EMTP. the Parameter of passive FSC is studied to get the right value. Simulation results show that Rr = 12 ohm and Rn = 1000 ohm in passive FSC. Furthermore, the passive FSC is tested with CVT load changes. The resistive and inductive loads are be varied to obtain comparative voltage and current value before and after the passive FSC is placed. Simulation results show that passive FSC can effectively mitigate the ferroresonance for each tested value load
