Abstract :
Different signal processing techniques are available for automatic detection and diagnosis of power quality disturbances. This paper describes the results of a comparison of the effects of frequency deviation on the accuracy of a number of widely used techniques for signal harmonic analysis, together with a means of mitigation of these effects.
