Harmonické v elektrických sítích

Abstract

This thesis describes the effect of exposure of harmonics...on the net, and considering the certain parameters of distribution network according ČSN EN50160. There are described the norms of power supply in the first chapter. The following chapters describe the creation, measurement, consequences and eliminate of harmonic nets. The practical part includes evaluation of measurement on the grid in the particular section and comparing the quality of the energy according ČSN EN 50160. There was used certain parameters governing the quality of electric energy (flicker, unbalance and harmonic voltage distortion factor) to evaluate the data.
