Abstract

All types of fluctuations of the rms voltage in power systems may be assessed by using a “flickermeter” which complies with the specifications given in IEC-EN 60868. In this paper, a digital flickermeter is presented based on the implementation in the frequency domain of the weighting filter block of the eye-brain simulation chain. The virtual instrument, implemented with an acquisition board inserted into a PC and with a software developed with the LabView tools, samples the voltage and furnishes the instantaneous flicker level and other severity coefficients. Results of simulated and actual data are reported to validate the performance of the developed flickermeter
