Analýza dat monitorování kvality elektrické energie

Abstract

This thesis deals with the observation of selected quality parameters of elektricity at different voltage levels of grid. content of first part of theoretical section is description of basic characteristics of all voltage levels. The folowing section provides examples of devices used for measuring and monitoring of power quality. The practical part is focused on evaluation of selected localities and comparing the quality of elektric power, mainly according to ČSN EN 50 160 ed. 3. There were used four selected power quality parameters for comparsion (flicker, harmonic distortion factor, asymmetry).
