The quality of electric energy in a low voltage public supply networks
Macoszek, Pavel ; Šlezingr, Jan (referee) ; Bok, Jaromír (advisor)
This thesis contains four main chapters, which describe qualitative parameters of supply voltage and measurement and analysis received information. The theoretical part consists of three chapters. Characteristics of low voltage are described in the first chapter. Next chapter describes disturbing events, which have influence on quality supply voltage, reasons for their occurrence spreading in network, eventually arrangement leading to the disappearance of disturbing events on other electric appliances in network. Last theoretical chapter describes measuring instruments of supply voltage. The purpose of these theoretical parts is to introduce the reader into supply voltage quality issues and can be used for preparation of measurement and evaluation of acquired data under norm ČSN EN 50160 (Voltage characteristic of electricity supplied by public distribution systems). An analysis of real network is the last part of this thesis. There is applied acquired knowledge with the aim of analysis of real states of qualitative parameters of supply voltage in network.

Cogeneration plants on vegetable oil
Macoszek, Pavel ; Baxant, Petr (referee) ; Radil, Lukáš (advisor)
The thesis is focused on cogeneration units on vegetable oil. The first chapter contains basic information about the production, supply and consumption of electric energy in the Czech Republic and about renewable energy sources. The following chapter is devoted to possibilities of use oil kinds of phytomass in the Czech Republic, or products made from them. Next chapter is mentioned on legislation allowing the use of used cooking oils for energy purposes. It contains a summary of the laws and regulations and options regarding subsidies for electric and heat power. The main objective of these chapters is to explain the issue of the establishment and operation of cogeneration units on vegetable oil. The following chapters are devoted to the design and study of simultaneously operated cogeneration unit on the vegetable oil with a combustion engine and the calculation of economic operation running. The reason of study is to evaluation, which on based of the input values and calculation methods determine the economic efficiency of the project cogeneration unit on vegetable oil under mode purchase price and mode green bonus. Appreciation is also given to the overall legal review and responsibilities of cogeneration units on vegetable oil.
