Abstract

Operasi switching yang tidak seimbang pada Circuit Breaker (CB) dapat menyebabkan tegangan lebih akibat feroresonansi di sistem jaringan distribusi. Faktor utama munculnya fenomena feroresonansi dipengaruhi oleh beberapa hal, di antaranya yaitu jenis konfigurasi belitan transformator daya tiga fasa itu sendiri. Studi ini membahas tentang karakteristik feroresonansi akibat empat macam konfigurasi belitan transformator daya tiga fasa yang umum digunakan di sistem jaringan distribusi. Jenis konfigurasi belitan transformator distribusi yang dianalisis yaitu transformator daya tiga fasa terhubung BintangBintang, Bintang-Segitiga, Segitiga-Bintang, dan Segitiga-Segitiga. Rangkaian sistem jaringan distribusi dan jenis konfigurasi belitan transformator distribusi dimodelkan dan disimulasikan menggunakan perangkat lunak EMTP/ATPDraw. Hasil simulasi yang diperoleh pada studi ini bahwa terdapat perbedaan karakteristik feroresonansi yang muncul dari perbedaan jenis konfigurasi belitan transformator daya tiga fasa apabila diberlakukan gangguan berupa operasi switching pada sistem. Transformator daya tiga fasa terhubung Bintang-Bintang paling rentan terhadap overvoltage akibat feroresonansi, sedangkan transformator daya tiga fasa terhubung Bintang-Segitiga memiliki pengaruh paling rendah terhadap overvoltage akibar feroresonansi. ================================================================= The switching operation of Circuit Breaker (CB) can cause overvoltage due to ferroresonance in the distribution network system. The main factor of ferroresonance phenomenon is influenced by several things, including the type of winding configuration of three-phase power transformer itself. This study discusses the characteristics of ferroresonance due to four commonly used winding configurations of three-phase power transformers in distribution network systems. The winding configuration of the distribution power transformer which analyzed in this study are three-phase distribution power transformer connected in Star-Star, Star-Delta, Delta-Star, and Delta-Delta. The circuit of distribution network systems and the winding configuration of distribution power transformers are modeled and simulated using EMTP / ATPDraw software. The simulation results obtained in this study are the differences of ferroresonance characteristics that appear from the various types of three-phase power transformer winding configuration when switching operation occurs in the system. The three-phase power transformer connected in Star-Star is the most susceptible to overvoltage due to ferroresonance, whereas the three-phase power transformer connected in Star-Delta has the lowest influence on overvoltage due toe ferroresonance.
