A Few Remarks About Notching Analysis-Case Study

摘要

This paper has been focused on the problem of analysis of notching occurring in electric power systems. Especially a choice of appropriate sampling frequency and its consequence for results of the analysis have been considered. Moreover, the problem of wavelet filter length and, in some respect, wavelet family has been analyzed as well. All analyses have been based on the real voltage samples, registered in the real isolated electric power system, namely ship's system, during two different electric power plant configurations. Finally, results of the research have been commented on with respect of its impact on a whole device for power quality analysis.
