Sledování vybraných parametrů kvality v různých napěťových hladinách distribuční soustavy

Abstract

This thesis deals with the observation of selected quality parameters of electricity at different voltage levels of grid. At the beginning of this work, general and guaranteed standards of quality of electricity supply are specified. It further describes the individual characteristics of electricity voltage, describing the quality of electricity supplied from public distribution network, based on standard ČSN EN 50160 and PPDS. The next chapter describes the issue of power quality parameters measurement. Work continues by comparing the selected network analyzers available on the Czech market. The practical part is focused on evaluation of selected localities and comparing the quality of electric power, mainly according to ČSN EN 50 160 . There were used four selected power quality parameters for comparison (asymmetry, flicker, harmonic distortion factor).
