Abstract (Summary)

In this thesis, the effects of voltage and frequency transients on the performance of residential loads are analyzed. We construct a setup for testing a number of single phase loads by using a power analyzer. Using the power analyzer, we record voltage and current waveforms and then analyze the results using MATLAB programs. We show that spikes of current appear and occur during over-frequency and frequency oscillations. Refrigerators have a self-regulated ability to adopt the new frequencies and come back to a steady state. After testing, the conclusion can be drawn that four out of six LEDs and both television sets have a constant power load profile. In contrast, the real power consumption of microwaves and refrigerators decreases as the supply voltage is reduced. These results suggest that LEDs, microwaves and refrigerators are in fact sensitive to frequency transients. However, plasma televisions and LCD televisions are highly resistant to frequency transients.
