Monitoring and Measuring of Power Quantities in Waterworks Facilities
Hála, Tomáš ; Pavelka, Tomáš (referee) ; Tichý, Vladimír (referee) ; Radil, Lukáš (advisor)
This Bachelor thesis deals with solution of an exact Smart metering problem. The goal of this thesis is to offer an electrical energy measurement innovation that deals with widespread waterworks objects maintained by Vodárenská a.s. Brno-venkov division. The paper contains an analysis of the current state of reading of electricity meters and the outlook on optimization. The paper also focuses on solving the smart metering problem and contains a description of individual layers of remote reading of electricity meters. The 2nd half of the paper focuses on the specific devices selection and design of data reading topology. An Economical analysis compares costs of project realization with possible savings with the help of chosen methods of financial analysis evaluates the economic effectiveness of an investment.

Smart metering
Lahodný, Libor ; Hrabina, Jan (referee) ; Szabó, Zoltán (advisor)
Semester paper describes the design of smart sockets and their management. Sockets are wirelessly controlled by a central unit. The socket has an integrated sensor, designed to measure current consumption of the device. If necessary, it can remotely disconnect the unit plugged in socket from AC network. Work includes analysis of individual system elements, design of electrical schematics and PCB. In the construction is included ethernet module, which is used to display data using a computer.. The device has been constructed and tested.

Voltage quality index for distribution systems voltage quality benchmarking
Hausner, Josef ; Topolánek, David (referee) ; Drápela, Jiří (advisor)
This Master’s thesis deals with design of a new method for voltage quality benchmarking using voltage quality index. This index should determinate total voltage quality in the power grid and compare voltage quality in different places. There is design of several algorithms which value measured parameters in this thesis. The best suitable algorithm is selected. Program for this algorithm was compiled in GUI Matlab. The algorithm is verified by using measured parameters in this program. The last part of this thesis is focused on possible usage of created algorithm.

Wireless data acquisition system
Kováč, Jakub ; Šťastný, Ladislav (referee) ; Fiedler, Petr (advisor)
The aim of this work is design of system for wireless data collection from energy meters. The work shows issues of smart metering and explains meters communication. There is designed and described concept of the system composed of RF modules connected to data concentrator. Designed RF module uses SoC radio CC430F5137 and it is connected to a data concentrator via RS485 bus. For the purposes of communication as well as firmware update, the communication protocol is designed. In the next part the work focuses on design and creation of RF module frmware, bootloader for RF module and software application for energy meter data processing.

Alternative Energy Sources and Their Integration into the Concept of Smart Grids
Kopička, Marek ; Procházka, Jiří (referee) ; Baxant, Petr (advisor)
This work deals mainly with electrical energy. In the first part is focused on alternative energy sources, and describes structure of consumption and production of electricity over the past few years, during which is focuses on renewable energy sources. In this context, assesses the conditions for alternative energy sources in the Czech Republic from the perspective of the legislative, as well as current status and potential of alternative energy sources and tries to predict the development of these issues. The next section describes the Smart Grids as a means to achieve these goals. There are presented the basic features of this system, its goals and challenges, a description of the integration of Smart Grids with other sources of electricity and the benefits of using Smart Grids both from the perspective of user and from the perspective of system. Other parts are focused on distributed control systems in the energy sector, its development and principle. The last part is devoted to consideration of the role of alternative energy sources and distributed generation in Smart Grids.

Systems for remote measurement in power engineering
Hudec, Lukáš ; Mlýnek, Petr (referee) ; Mišurec, Jiří (advisor)
The work deals with the measurement and management in power. Provides an introduction to the problems of remote meter reading, management, and describes the current situation in the field of modern technologies Smart metering and Smart grids. It also analyzed the issue of collection of networks and data collection from a large number of meters over a wide area. For the purpose of data transmission are described GPRS, PLC, DSL, ... Further, there are given options to streamline communication. This area is used hierarchical aggregation. Using k-means algorithm is a program designed to calculate the number of concentrators and their location in the group of meters. The finished program is written in Java. It has a graphical interface and shows how the calculation is conducted. To verify the results of the optimization program is given simulation model in OPNET Modeler tool. Audited results are described in the conclusion and can deduce that using the optimization program is to streamline communications.

Innovation of information systems in enterprises, particularly in the utility market segment
Maloš, Martin ; Žid, Norbert (advisor) ; Tůma, Jiří (referee) ; Hübner, Miroslav (referee)
This thesis addresses the innovation of information systems in enterprises, particularly in the utility market segment. The thesis starts with a definition of utilities, a market segment containing companies involved in generation, transmission, distribution and retail of energy services as well as other companies providing related networked services. The aims of this thesis are both theoretical and practical. The theoretical part offers a new theory for IS innovations for the selected segment and for the relation between the innovation and the architectures of IS. In the practical part, the author identifies current challenges and opportunities in the selected market segment and offers scenarios and visions for future development. The first part of the thesis maps out the general innovation theories in the context of the selected topic. The second part introduces a new innovation theory based on an analysis of the specific conditions in the utility market segment. The next section focuses on the topic of IS architecture and its ability for tracking and managing the changes of the IS during the innovation process. The following part relays designs for specific architecture models supporting the current innovation trends in the utility market. The final part of the thesis summarizes particular business recommendations for innovation procedures in utilities, identifies innovation opportunities, and inspires visions for the future development of the market. The opportunities are related to a new way of understanding the role of IS in utility companies. IS provides a portfolio of information services to support the customer oriented business services, advanced services with added value and tailor made services for specific customer groups.
