Abstract:

Use LHE ( Energy Saving Lamp) that use electronic ballast will cause harmonics, both current and voltage harmonics and the harmonics will result in apoor electric power quqlity. On the anther hand LHE that uses electronic ballasthave good properties in converting electrical energy into light, because it has an effiency of above 80%. This research aims to analyze the activity electric power quality in the distribution network due to load LHE with electronic ballast. We then measured with a laboratory scale and continued analysis using the program, for the issues analyzed include: the use of ellectronic ballasts will cause harmonic currents and voltage, harmonics and odd harmonics influential 3rd harmonic dominan, harmonics will effect the quality of electric power.Thus will follow up effort to minimize the presence of harmonics in particular harmonic currents and harmonic influence further analyzed for capacity LHE group with large- capacity load on the distribution network.
In order to save electrical energy, mainly for lighting, save energy- saving- lamps can be used. Those lamps, which use electronic ballast and added by hybrid filter, can reduce negative effect due to harmoni, so that efficient condition in load and optimal condition in distribution network can obtained.This study was carried out by simulation with PSIM program vertion 9.0 and a reference to minimize current harmonics in such energy- saving- lamps using electronic ballast to increase the quality of electrical power.
Result of the study show that thereduction in large current harmonics of 10% due to AC-DC rectification was because of electronic baalast use. And the anther have to support up the EPQ at 1.24%, to be give at the standard IEC 61000-3-2 Class C to follow up.
