摘要: The study provides the theoretical basis for use of wavelet packet transform (WPT) method RMS and power/energy measurements. proposed can simultaneously measure distribution quantities power with respect to individual frequency bands directly from coefficients associated concurrent voltage-current pair. Their dependent such as factor total harmonic band distortion also be calculated. Uniform result WPT decomposition system waveforms used identification harmonics. retain both time relationship original waveforms, which is one major benefits provided by this method. evaluated its application simulated actual waveforms.
