Evaluation of data from long-term voltage quality measurements in the 22kV network
 Umlauf, Aleš ; Klusáček, Jan (referee) ; Topolánek, David (advisor)
This bachelor's thesis works with data that were measured by fourteen power quality analyzers in the analyzed area for a period of approximately 7 months. At the beginning of the work, the method of aggregation together with the limits for characteristic parameters of electrical energy is determined, according to the applicable ČSN standards. The main contribution of this work is the summary evaluation of the characteristic parameters of electric energies. In the end, the work focuses on a detailed analysis of the effect of system operation on Flickr with the aim of estimating the area of the cause of the poor quality of electricity. The influence of voltage outages and data inconsistency on the evaluation of the quality of electricity is emphasized.
