| dc.description.abstract | Flicker is defined as the state of unsteadiness of visual sensation induced by a light source whose luminance or spectral distribution varies with time. The basis of flicker is usually the use of large loads having quick fluctuating power demands. Humans can be sensitive to light flicker caused by voltage fluctuations. Our vision can be weakened with flicker and may cause discomfort and fatigue. In some situations, it can even result to accidents in workplace due to operator fatigue and reduced concentration levels. The objective of this thesis is to monitor the flicker by using suitable wavelet and to remove the flicker from the supply of General Service Connections (220 V supply). The thesis puts forward a method which uses a Wavelet based flicker analysis system where MATLAB and LabVIEW are integrated together to extract the characteristics of flicker. It can detect the amplitude modulation waveform of the voltage flicker, examine time and frequency content. After the analysis of the signal a control signal has been applied to overcome the effect of flicker. | en |
