Abstract

One of the most challenging discussions in distribution companies is power quality. Harmonics is one of power quality issues which generated in any non-linear electrical/electronic systems. The presence of harmonics in distribution networks can lead to various problems in terms of performance and operation. High-pressure sodium (HPNa) lamps are currently the main lamps used in public lighting. However, the possibility of using high-power light emitting diodes (LEDs) for street lighting is growing continuously due to their greater energy efficiency, robustness, long life and light control. In Alexandria Electricity Distribution Company (AEDC), public street lighting sector constitutes around 3.7% of the total consumption. A suitable selection of the lamp type is very important. In Alexandria, most lamps are HPNa, with rare high-pressure mercury and compact fluorescent lamps. Large connecting roads are mostly HPNa, sized 400 or 250 W, and mounted on 12 m poles. City lamps are a mixture of HPNa 400, 250, 150, 100 and 70 W, mounted on short poles (3-7 m high) or long poles (8-12 m high); but nowadays LED lamps are being presented as a more energy-efficient alternative. AEDC started to replace HPNa, sized 400 or 250 W with LED lamps 100 or 60 W which leads to decrease the total street light consumption from 4% in 2014 to 3.7% in 2015 and green house emission. The aim of this study is to study the power quality lighting street networks based on LED and HPNa lamps. Measurements carried out to HPNa lamps with electronic ballast and LED lamps and compared with IEC61000-3-2 limits. It is shown that measured values are less than the limits given in IEC61000-3-2.
