000000013 520__ $$aSpectral representation of waveform distor-tions has been of great interest in power systems for many years since the disturbing loads generate a wide spectrum of components which deteriorate the quality of power supply. When spectral components are time-varying in amplitude and/or in frequency – such as in presence of arc furnaces and adjustable speed drives - high resolution methods should be applied due to their capability of cap-ture these changes in time. In this paper the Prony and ESPRIT high-resolution methods are used to analyse simulated non-stationary waveforms in a supply system of a DC arc furnace. The analysis has been completed before and after the inclusion in the system of several compensa-tion devices (STATCOM, Active Filter, Passive Filter and a hybrid of STATCOM and Active Filter). The main con-clusion of the paper is that Prony and ESPRIT methods are useful tools also for the control system design; in fact, they allow capturing time variations of spectra compo-nents better than most usual techniques such as Fourier-based methods.
