Unwarranted Energy Consuption Occurence Analysis Using of On-line Consuption Evaluation Provided by Remonte Reading Instalations
Samuel, Tomáš ; Kristek, Petr (referee) ; Orságová, Jaroslava (advisor)
The target of this project is to show the analyses of unauthorized subscriptions electricity consumption and provide the option of distribution networks screening on-line through istalment the devices providing remote control. This way of elimination the causes of unauthorized consumption has been not commonly used in the Czech Republic yet, it is pre-pilot project. We should be announced about the ways of measuring the electricity consumption used in past and nowadays. At present, there is a significant increase in case of unauthorized donations of electricity. Operators of distribution networks pay increased attention to these issues and develop efforts to reduce non-technical losses in the distribution and trade in electricity, which in its consequences lead to increase in costs with an impact in electricity prices. On business conditions and performance of government in the energy sectors and amendment of some laws the definition of certain terms of irregular donation electricity characterized by the provision of energy bill, which is a precondition for their qualifications. The analyses of unauthorized consumption based on on-line measuring with tending to make it easier and cheaper is useful for future, of course it might substitute the pretty expensive ways of measuring actual energy consumption. The result of it should by presentation of numeric energy flux diagram. There is a growing frequency and social insecurity of unauthorized of electricity and it is primarily on the distribution system operator, consistently privileges resulting from the energy bill and other generally binding regulations. The system lead to revealing unjustified interference with measuring equipment for which data on consumption are registered or recorded incorrectly or other useful functions.

Influence of Distributed Generation on Given Area of 22 kV Distribution Network
Samuel, Tomáš ; Bráblík, Libor (referee) ; Orságová, Jaroslava (advisor)
The Thesis deals with the current problem related to the connection of dispersive sources to the distribution network. The advantageous legislative support, however, gives a rapid rise to the sources of this kind. Current pricing philosophy favours in particular the growth of photovoltaic power plants. The introduction is aimed at the dispersive sources locating so as to give a comprehensive solution and better understanding of this issue. The equipments of this kind are located in accordance with legislation in force; however, it is necessary to formulate the possibilities of placing them from the view of rational use of the area with the aim of the public weal accordance of both public and private interests. Talking about connection of the new dispersive sources to the distribution network, it is important to mention the legislation, legal directives and regulations delimitating this kind of trade. This theme is the subject of another chapter of the work. Particular attention is paid to the regulation on conditions of connection to the distribution network. When connecting the sources to the distribution network the biggest technical problem from the view of electrical engineering is undesirable influence on the quality parameters (voltage) in this network. This is in particular the voltage change after connection, then, depending on the type of source, the emission of the current harmonic, sharp voltage change, etc. Considering current rise of the dispersive sources connected to the distribution network, more and more influence will appear in quantity parameters. For this reason there will be a lot of search for the methods of preventing from the negative influence on the network. From all of the above said reasons, the work is aimed at the operation analysis of the part of the distribution network, calculation of the network qualitative parameters and searching for the methods of negative influence rectification owing to switching processes of the distribution system. So as to determine the quantitative parameters we used the E-influence programme. Final paragraphs are devoted to the changes to come not only in legislation but, in general, in the approach of the distribution system operators not only to the ways of another connection of such sources but even the regulation of the dispersive sources already connected.
