Wavelet and Wavelet Packet Compression of Power System Disturbances
IEEE Power Engineering Review(2001)
摘要
This article introduces a compression technique for power disturbance data via discrete wavelet transform (DWT) and wavelet packet transform (WPT). The data compression leads to a potential application for remote power protection and power quality monitoring. The compression technique is performed through signal decomposition up to a certain level, thresholding of wavelet coefficients, and signal ...
