DSP Based Continuous Wavelet Transform Algorithm for Detecting Power Disturbance
Wavelet Transform(WT) possesses good time-frequency domain characteristics and is able to collect the time-frequency parameters of signals simultaneously,it is a powerful tool for power quality analysis.The analyzing method used in this paper is by continuous wavelet transformation and the complex Morlet wavelet with good frequency domain characteristics is chosen as base wavelet to process power disturbance signals,and the validation is through digital signal processor(DSP).The results show that from given sample data the algorithm can collect the various characteristic parameters of the disturbance signals precisely.Thus it proves that it is an effective means for accurate detection of power disturbance.
