Numerical Modelling of the Light Source
Pavelka, Adam ; Koňas,, Petr (referee) ; Kadlec, Radim (advisor)
The master’s thesis deals with photometry units used in light engineering. There are defined the methods of modelling the illumination systems, their advantages, disadvantages and possibilities of using. Furthermore, the thesis deals with modelling of two illumination systems by ray-tracing in programming environment of MATLAB. The master’s thesis describes the analysis of the problem and the program designing process. Acquired model results are then compared with the real measurements of both illumination systems which allow the discussion of the results and the deviations of the models.
Innovating a laboratory task: Inspection of electrical wiring and devices
Klement, Petr ; Steinbauer, Miloslav (referee) ; Kadlec, Radim (advisor)
The bachelor thesis deals with the innovation of laboratory tasks, called Inspection of Installation and Equipment. The aim is to construct a device that will be able to simulate errors during the inspection on the appliance. The task will be extended to build the appliance itself, which will be measured and further simulated errors. The REVEXprofi digital measuring instrument will be used for measurement. The safety of the device will be ensured by the measuring properties of the REVEXprofi instrument, by storing the circuit inside the built-in device and by the small overlaps of the measured values above the standard when the error is triggered. The circuit was simulated using the TINA 9.0 program.
A Practical Panel for Smart Home Wiring
Pospíšil, Josef ; Steinbauer, Miloslav (referee) ; Kadlec, Radim (advisor)
This bachelor thesis deals with intelligent installations in buildings using centralised system inels. Individual components of this system, such as the central unit, power supply and separators, are described. Used busbars and their connection possibilities are mentioned in the next part together with different ways of access to the central unit. The thesis also includes the visualisation of the demonstration panel, which will be used as a model in laboratories. Next part consists of the basic functions simulation and verification of their functionality. Finally the formation of the panel together with its connection and programming is described. The panel documentation is enclosed at the end of the thesis.
A Sample ARC Detector Panel
Pala, Lukáš ; Valenta, Jiří (referee) ; Kadlec, Radim (advisor)
In the introduction an electric arcs creation in low voltage networks is discussed, followed by evaluation of verification measurements with AFDD. A serial arc generator is designed in accordance with easy manipulation and low maintenance requirements. Technological solution for safe fault simulation is described similarly as particular function sections of demonstration panel. Schematic diagrams of power and electronic circuits are attached.
Design of Measurement Net
Krajčír, Róbert ; Drexler, Petr (referee) ; Kadlec, Radim (advisor)
This thesis deals with transfer of measured data from sensors placed on pulse power generator for long distances in areas with strong outer interference. Main goal is to design fast and reliable network. Therefore some basic transfer methods, which are available for usage, are analyzed. Regarding to the characteristics of these methods, the most suitable option was chosen, which is analog fiber optic link. In the next phase, the concept of the network itself is dealt with, including analysis and choice from variety of modulation techniques, transmitters and recievers and their characteristics. Variety of drive and amplifier circuits are also mentioned, with emphasis on their influence on transfer and noise attributes and available bandwidth. Based on theoretical analysis and component pros discovered, exact parts are chosen and complete concept of the network is established, including auxiliary circuits. According to this concept printed circuit boards for both transmitter and reciever are made and tested.

We can find also an overview of known intelligent systems and a brief description. In the second part we describe itself proposal of concrete building, step by step. We can find a description of a created program to control building. The third part is focused on theoretical information about photovoltaics. Here we explain the basic principle, the limits of technology, materials and the panel structure. In the fourth part we proceeded to the actual plant proposal. Here we find the principle and a block diagram of system and description of the components of the plant, evaluation of production and energy consumption. Drawings of the technical documentation wiring as a photovoltaic power plant, distributor scheme and its layout can be found in the technical report, in Attachment.
Design of switchgear system
Róža, Štefan ; Slavata, Petr (referee) ; Kadlec, Radim (advisor)
The thesis depicts the substation of low voltage switchgear design (nn) based on the back scheme of its connection. In the first part of the switchgear design nn the thesis deals with the adjustment of the back connection scheme and its analysis necessary for continuation of its switchgear designing. The main part of the thesis describes the scheme creation in a computer program, the implementation of certain computations requisite for safe and failure-free operation of the station. Here, the thesis points out the solutions of conditions, where the back scheme does not agree with the calculated results. The circuit was tested for voltage drop and load decomposition, symmetrical 3-phase short circuit and 1-phase short circuit. Further, the thesis dwells on the switchgear designing of low voltage switchgear. Finally was created in 3D visualization and treated bid for the material needed for the production of switchgear system, production of switchgear system and UPS.
Optimal Design of a Low-Frequency Structural Wiring System
Balák, Dušan ; Slavata, Petr (referee) ; Kadlec, Radim (advisor)
This thesis is concerned with designing and optimizing of a low-frequency structural wiring system in office building. The thesis is divided into two parts, theoretical and practical. Theoretical part is describing factors of designing the low-frequency structural wiring system, with focusing on short-circuits and their consequences on wiring system. Mentioned are optimal economic diameter of electrical cables, purchase and running costs and other factors connected with the optimal designing and protection of electrical devices. In practical part is adjusted, CAD´s system program, assigned a site wiring diagram and allocation of switchboards in the office building. In programs by EATON Elektrotechnika company were developed another parts of project´s documentation. In the Spider program was drew the wiring diagram assigned building and suggested cables and circuit breakers by EATON for correct running in the whole building. In the M-Profil program are designed assigned switchboards and calculated their warming. The motion includes prepared projection documentation, means site wire diagram of the building, schema with evaluations of short-circuits and voltage loss, switchboards design and calculation of their warming.
