Interaction of power quality disturbances within 2-150 kHz (supraharmonics): Analytical framework

Abstract

Disturbances interaction at supraharmonic range (2 150 kHz) between two lighting devices and a power source is described in this article by means of an Electrical Power method. Currents and voltages were measured from a LED lamp, a CFL device and an AC Power Source under normal operation in order to describe how conducted disturbances interact within the 2 150 kHz frequency range. From an Electrical Power point of view, the devices used are described as Power-sharing agents and therefore the disturbances observed from their operation can be exchanged not only with their electric neighbourhood, but also throughout the Frequency Domain. This method can be used for the Interaction Description in Frequency Domain of steady-state disturbances between devices without directly considering the impedance behaviour of such devices.
