Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh dari pemasangan pembangkit terdistribusi (Distributed Generation) terhadap magnitude arus gangguan hubung singkat pada lokasi gangguan pada sistem distribusi tenaga listrik. Dalam penelitian ini, sistem tenaga listrik dan pembangkit terdistribusi dimodelkan kedalam aplikasi Alternative Transient Program (ATP). Simulasi hubung singkat dilakukan dengan berbagai kondisi yaitu variasi jenis gangguan hubung singkat (dua fasa, dua fasa ke tanah dan tiga fasa), variasi lokasi gangguan serta jumlah dan lokasi pemasangan distributed generation. Hasil penelitian menunjukkan bahwa dengan adanya penambahan distributed generation dalam sistem distribusi tenaga listrik, maka arus gangguan akan meningkat dibandingkan dengan arus gangguan sebelum adanya distributed generation pada sistem tenaga listrik, khususnya ketika gangguannya terjadi didekat pembangkit terdistribusi. Jenis gangguan, Jumlah dan Lokasi pemasangan pembangkit terdistribusi mempunyai pengaruh terhadap magnitude arus gangguan hubung singkat.
