Abstract [en]

This paper presents measurements of the changes in phase angle of the harmonic current for a domestic costumer due to the introduction of energy-efficient lamps (compact fluorescent lamps and light-emitting diodes lamps). Those results are then compared with the aggregation rules according to standard IEC 61000-3-6 and with a mathematical model, in order to highlight the importance of using phase angles in the harmonic estimations. The paper presents both the emission from individual household devices and the variations in the complex harmonic current from a group of devices. Cancellation because of phase-angle difference plays an important role in the emission from a group of different devices. This explains why the increase in emission after changing to energy-efficient lamps is much smaller than expected. Some other power-quality parameters are also considered such as total harmonic distortion, total power factor, and displacement power factor. It is concluded that the complex plane presentation is a useful tool to estimate the harmonic emission from a group of domestic appliances.
