Analýza kvality elektrické energie v průmyslovém objektu

Abstract

This bachelor's thesis focuses on the measurement of power quality in electrical networks, with a specific emphasis on the analysis of higher-order harmonic frequencies. The theoretical part describes the operation of networks according to the ČSN EN 50160 ed.3 standard, including the changes introduced in amendment A3. This section of the thesis focuses on the processing of measured signals and subsequent Fast Fourier Transform (FFT) analysis using the mathematical software Scilab. The practical part describes the measurement process using the ENA BK500 network analyzer from ELCOM, which is designed for network analysis and evaluation of parameters defined by the standard. The measured object was an asynchronous motor powered by a frequency converter in an industrial line at Tridas s.r.o. company.
