Obnovitelné zdroje a jejich začlenění do distribuční soustavy.

Abstract

The bachelor thesis deals with the issue of the renewable sources and their connection to the distribution network. At first there are the transmission of the electric power from the place of production to the place of consumption, the particular levels of the voltage that are used for the transmission and finally the service of the distribution system described at the beginning of the thesis. The following part of the thesis describes at first the principle of the production of the selected renewable energy sources. Then it goes into the history of these sources and finally it shows their advantages and disadvantages. The other part of the thesis works with the feedback effects on the electrified distribution network that could be caused by the properties of the renewable sources. This part includes the changes of the voltage, the influence of mass remote control devices signal or flicker. At the end of the theoretical part of the thesis the terms and limits of the connectivity of the individual power plants are described. The practical part of the thesis includes the calculation and assessment of the voltage drop in the 22 kV line with the unconnected and connected renewable source in the distribution system.
