Abstract: 

This paper presents harmonic analysis of power quality disturbances in scale-frequency domain. A suitable scheme has been proposed for power signal analysis using orthonormal harmonic basis functions with compact support.
These basis functions are band-pass in nature. One can choose filter center frequencies easily. It has been shown that the respective band-pass filter outputs are associated with harmonics of the distorted power signal under consideration.
Hence, the present scheme may be useful for harmonic analysis of power quality disturbances. Moreover, this technique provides a precise scale-frequency analysis.
