An Improved Power Quality Evaluation for LED Lamp Based on G1-Entropy Method

Nowadays, light emitting diode (LED) lamps have been widely utilized for lighting system due to its low-energy consumption. The harmonic emission standard is ignored by most of the manufacturers, high current will increase injection and cause fire risk. Existing research focuses on investigating emissions from several specific LED drivers, but a systematic evaluation approach not given. contribution this paper proposed in management view, which can evaluate harmonics lamps, accelerate elimination inferior improve power quality distribution network. combines G1 method entropy method, make weighting more scientific rational. An model established collecting data, then G1-entropy used calculate weights characteristics model. Finally, we analyze discuss results, proposed, thoroughly accurately represent lamps.
