Abstract

The content of this diploma work is analysis and casual analysis that cause shutdown PC-backup source UPS on the pit Karviná – establishment ČSA with respect to electromagnetic compatibility and the possible occurrence of harmonic disturbances in distribution networks, ČEZ, a.s., Dalkia ČR, a.s. and OKD, a.s. In the work be described electrical arrangement diagram with operational and mutually-disturbing features of major connected appliances at various configuration whole distribution net. Work is also focused on the description and characteristics haulage engine with twelve-pulse controlled, which is a source of large quantities of voltage harmonic frequencies with return adverse impact on the supply mains.
