The design and implementaton of programmable CPLD based smart microcontroller education set

Abstract

Fluorescent and LED lamps are the most common used light sources both in homes and offices due to their low energy consumptions. However both sources are short of the quality of power factor, harmonic components and colour rendering. Taking these parameters in account, the purpose of this study is to investigate and compare energy quality parameters for different light sources used with lighting control, especially dimming control. To that end, energy quality parameters as harmonic current values, total harmonic distortion and power factor of LED and fluorescent lamps in lighting control, under different scenarios and dimming are measured, analysed and suggestions made to evade the disruptive effects both on electricity network and local lighting control system.

Flüoresan ve led aydınlatma kaynaklarının enerji kalitesi parametrelerinin incelenmesi ve karşılaştırılması

Abstract

Flüoresan ve led lambalar, düşük enerji sarfiyatları sebebiyle, evlerde ve ofislerde kullanılan en yaygın aydınlatma kaynaklarıdır. Bununla birlikte her iki kaynağın güç faktörü kalitesi, harmonik bileşenleri ve renk işlemeleri düşüktür. Bu çalışmanın amacı, farklı aydınlatma kaynaklarında aydınlatma kontrolü yaparak, özellikle karartma (dimleme) kontrolü, enerji kalitesi parametrelerini incelemek ve karşılaştırmaktır. Neticede, Led ve flüoresan lambaların, farklı senaryolarda ve dimlenerek yapılan aydınlatma kontrolünde ölçülen ve analiz edilen harmonik akım değeri, toplam harmonik distorsiyon ve güç faktörü gibi değerlerin ışığında, elektrik şebekesi ve lokal aydınlatma kontrolü sisteminde yıkıcı etkilerini önlemek için önerilerde bulunulmuştur.
