POWER SYSTEM ANALYSIS UNDER FAULT CONDITION

OBJECTIVES

Kursus ini memberikan pengetahuan dan keterampilan tentang analisis system daya di bawah kondisi gangguan (fault), pada suatu system pembangkitan, transmisi dan distribusi listrik. Dalam kursus ini akan dijelaskan antara lain Representasi system daya, gangguan listrik, gangguan tiga fasa simetris, model matematika, komponen simetris, gangguan tak simetris, studi stabilitas dan beberapa contoh kasus atau simulasi.

Dari hasil kursus ini diharapkan para peserta kursus dapat memiliki dan meningkatkan pengetahuan serta pemahaman terkait dengan Power System Analysis Under Fault Condition pada system daya kelistrikan.
