PROJECT TITLE :

An Evaluation of the Extent of Correlation Between Interharmonic and Voltage Fluctuation Measurements

ABSTRACT:

The existence of a general correlation between measured interharmonics and measured lamp flicker would be very important. Gift measurement and emission limitation standards for voltage fluctuations are primarily based completely on the 60 W incandescent lamp's response to amplitude modulation of the power frequency. As use of incandescent lamps declines, the requirement increases to broaden voltage fluctuation quantification beyond lamp flicker. Amplitude modulation of the facility frequency is mathematically corresponding to interharmonics summed with the ability frequency. This, with the existence of international standards for measuring interharmonics, has advised interharmonics as a attainable basis for characterizing voltage fluctuations more broadly. Moreover, interharmonic measurements could be inherently extendable to quantify the effects of voltage fluctuations on devices different than incandescent lamps. But, any new technique that offers advantages in broadening voltage fluctuation measurement must be capable of matching the results of gift practices. Thus, interharmonic measurements should 1st be demonstrated to be typically correlated to currently accepted flicker severity measurements. The correlation between these measurements is explored in this paper. It is concluded that by using the techniques during this paper, measured lamp flicker and measured interharmonics are correlated to a large extent for most industrial loads.
