Power Signal De-noising Based on LabVIEW and Wavelet Analysis
Power signal of some equipment is typically non-stationary and nonlinear; inevitably, there are lot kinds of yawp which need being disposed. Compared with traditional filter de-noising, the time frequency character of wavelet transform is perfect, and it is one effective tool of analyzing non-stationary signal. This paper introduces threshold de-noising based on wavelet transform, In virtue of LabVIEW plate, by simulating test, minimal threshold de-noising is compared to maximal threshold de-noising, and selected different wavelet function for de-noising, the validity of threshold de-noising based on wavelet transform is proved in the process of power signal de-noising.
