Analysis of distorted waveforms using parametric spectrum estimation methods and robust averaging

Leonowicz, Z (Institute of Fundamentals of Electrical Engineering, Wroclaw University of Technology, Poland)


Abstract: After the description of parametric methods (ESPRIT and MUSIC) and selected robust location measures (robust averaging methods), the comparison of the frequency and amplitude estimation error, based on numerical simulation is presented. Next part presents basics of selected power quality indices (harmonic sub/groups), followed by comparison of estimation error in the case of application of FFT-based algorithms and parametric methods as well as presentation of advantages of use of robust averaging.
