S. Lewis, V. Nuño, E. Barocio, Pavel Zúñiga, Felipe Alejandro Uribe · 2015
This paper presents a Kalman-Wavelet transform technique for tracking harmonics in the dynamic state. The presented method combines the discrete Wavelet transform and Kalman filter to track a current or voltage waveform, producing time varying states. The results obtained are compared to other Kalman methods to prove its estimation quality, numerical accuracy and short simulation time.
