Abstract :
This article presents a brief study of flicker propagation and attenuation along a network. A DLL routine was implemented to emulate a digital flickermeter capable to run with commercial network simulation software. The voltage fluctuations are obtained by load modulation on the simulator. The results confirm some expected results, such as the influence of the short-circuit ratio and the voltage regulating effect of rotating machines upon flicker attenuation. A methodology to estimate flicker transfer factors is also presented.
