| Abstract: | On the basis of wavelet transform theory and with the features of power quality detection data, a threshold method based on wavelet transform coefficients are applied to the compression of power quality detection data. The results from simulation and calculation and their analysis show that the presented method is fast and simple and possesses goodcompression effect. The partial features of compressed signals can be retained. So it is suitable to the cases where thereal-time data compression is required.. |
