Vyhodnocovanie parametrov kvality elektrickej energie v distribučných sieťach

Abstract

This thesis deals with three primary chapters, first one is description of qualitative parameters of supply voltage as well as measurment and data evaluation issues. Theoretical part describes basic characteristics of supply voltage and limits based on standard specification. Next chapter deals with specification of measurment devices used for supply voltage quality measurement. The purpose of these parts is to introduce reader into supply voltage quality issues and can be used for preparation of measurement and acquired data evaluation under norm ČSN EN 50160 (Voltage characteristic of electricity supplied by public distribution systems). An analysis of real network is the last part of this thesis, in which application of acquired knowledge on assigment of real states of qualitative parameters of supply voltage in network.
