Abstract: - The energy efficiency of the compact fluorescent lamps (CFLs) is the main motivation of the
promotion policies to replace the tungsten filament bulbs with them. However, their high harmonic content was
always a problem for the power quality of the networks, especially the ones with a considerable share of other
non linear loads (computers, TVs, electronic devices etc). That problem cannot be neglected in cases of
installations with high lighting load (office buildings, educational facilities, hotels etc). In that case the
replacement of incandescent lamps by CFLs may cause problems to the power quality. This paper presents an
analysis of the low voltage network of a typical electrical installation of a hotel, where lighting is one of the
main loads. The complete network is simulated (up to the transformer) using the impedance network model.
The CFLs are simulated using their electrical characteristics (active and reactive power, power factor, harmonic
content etc) that have been measured in the Laboratory of Photometry of NTUA. The contribution of CFLs to
the total load of the network is determined under different scenarios for the scale of replacement of
incandescent lamps. For each scenario, the total harmonic distortion (THD) is calculated at each busbar of the
network and then it is compared to the respective THD before the replacement. As expected, some scenarios
give a non-negligible harmonic distortion although it is always below the upper limits (IEC, IEEE). However,
some scenarios (large-scale replacement) may not be realized due to their high harmonic content that will be
added to the distortion by other non-linear loads. That means that in case of networks with high lighting loads,
the large-scale installation of CFLs should always be studied before replacing the incandescent lamps.
Considering the existence of other non-linear loads, the distortion may exceed the maximum allowed values
leading to unacceptable power quality.
