Model for power line communication
Baluch, Viliam ; Fujdiak, Radek (referee) ; Mlýnek, Petr (advisor)
This bachelor thesis is dealing with matters of data communication after power line. The thesis is including the PLC systems history, current possibilities of utilization and different types of modulations being used, interference sources and parameters of a transmission line. We will elaborate on methods of transmission line modeling and one of them will be used in the practical part of the thesis. The practical part consists of modeling of different types of topology and impedance endings applying generation of random transmission parameters and sizes of typology. We analyze results from practical measurement which are incorporated in a model. The model is then being compared with another one in terms of fixed parameters.

Power line grid model
Csiba, Patrik ; Sláčik, Ján (referee) ; Mlýnek, Petr (advisor)
This diploma thesis analyzes the PLC communications in various scenarios. The first part of the thesis describes the principle of narrowband and broadband communication and the analysis of electrical lines. The next part describes the NS-3 framework, simulation scenarios for establishment the effect of branches and other parameters on the baud rate. The last part determines the minimum number of repeaters and their location on the extended topology.

The Models of Power Lines for PLC Data Communication Systems
Fajkus, Petr ; Mišurec, Jiří (referee) ; Lázničková, Ilona (advisor)
Bachelor's thesis is focused on the issue of data communications over power lines. This technology is known as PLC (Power Line Communication). Wider deployment of this technology into practice at present prevents a number of shortcomings. Main problems are disturbance useful signal on power lines, radiation interference, small reach of useful signal and elements of energy network, which affect the transmission. In the analysis of sub-problems, it appears that it is appropriate to have a computer power line model, allowing a computer simulation of data communication over power line. It is necessary to combine two different, conflicting requirements. Power lines are not primarily intended for data communication, and data lines are not designed for the transmission of electricity. Both types of line are described the same primary parameters, but they operate in completely different modes. This thesis examines these modes and possible models of power and data lines in terms of data communication. The main part is devoted to the draft power line model for data communication and computer verification of the functionality of the new proposed model.

PowerLine Communication for LED unit control
Šebesta, Ondřej ; Janáková, Ilona (referee) ; Honec, Peter (advisor)
This diploma thesis deals with the design and testing of a system for powerline communication, enabling control of LED lights. The work first describes the basic principles of powerline communication, specifies the communication bands and summarizes the basic functional requirements for communication within the system for LED lighting control. It also describes the method of selecting a modem for powerline communication, the design of a test module with this modem and also the method of testing real communication between two test modules, including test results. The most comprehensive part of the work describes the design of hardware and software of the universal PLC module and how to use it. In addition, it referes to the development tools used as an example of implementation in LED lighting. At the end of the work are summarized the results of testing the proposed system.

Data Concentrator for Smart Grids
Franek, Lešek ; Beneš, Bedřich (referee) ; Kučera, Pavel (advisor)
The goal is to design data concentrator for Smart Grids. Data Concentrator provides the interface between the server systems of distribution companies and end devices, which are electricity meters, water meters, gas meters and other equipment. There are hardware and software design solutions and there is also discussed creating its own distribution of Linux.

Multi-Conductor Model of Communication over Outdoor Power Lines
Franek, Lešek ; Steinbauer, Miloslav (referee) ; Vozňák, Miroslav (referee) ; Fiedler, Petr (advisor)
PLC - power line communication is not new. It has been known for many years. But It never be used in massive scale. There were only sporadic applications, for example ripple control system HDO used in the Czechoslovakia. PLC currently experiencing a renaissance thanks to the advent of Smart Grid. PLC offering relatively low bit rates and relatively unreliable transmission, but these disadvantages compensates very low costs to build a communication infrastructure and it offers specific functionalities for Smart Grid. The question is whether the declared parameters will be met in the real world. This thesis tries to find an answer.
