Research on the Methods of Interharmonics and Flicker Limit Curve

Abstract:

In order analyze the inter-harmonic affections on the voltage flicker, the relationship between the inter-harmonics and flicker analysis are carried out. In order to be able to accurately determine the level of inter-harmonics to make the electric light flicker, interharmonic-flicker limit curve drawing method based on the voltage flicker constraints is established. And according to IEC lamp-eye-brain model, analog tester flicker and interharmonic-flicker experimental platform are built; limit curve can be drawn through the experimental data. The 2 kinds of harmonic-flicker limit curves for the 220 V, 50 Hz fluorescent lamp are drawn by the 2 methods separately, and the analysis results show that the accuracy of the results obtained by the two methods, the level of interharmonics whether lead to fluorescent flicker can be determined by the curves. The methods have the small amount of calculation, and are practical and easy to implement.
