ANALISIS KUALITAS DAYA PADA SUPLAI DAYA LISTRIK PT. SOSRO

Abstract

In more than ten years, quality of electricity has growed from clearness to be an principal issue. One heavy problems from quality of power is harmonic distortion and its consequences. Particularly, the increasing of penetration of loads bases on power electronics (non-linear load) what creates a harmonic distortion in AC power systems. Then, quality of electricity becomes principal issue for utility and its consumer and both swiftly adopts philosophy and proposes limits in new international standard (IEC, EN, BS, IEEE). As consequence the equipments of power conditioning (converter) will become more important for electrical utility and its consumer. From the results with the data logger recording at PT SOSRO distribution feeder system found that there are several current and voltage harmonics are significant in the load and hence the supply side. Fifth and the seventh Harmonic are heaviest harmonic components in the current load. Installation of passive filters will be one solution to overcome the issue with the current harmonics. The recomendation proposed will be submitted to management for consideration PT SOSRO factory in determining which type of passive filter will be used.
