Testbend for dynamic loading of electric drives
Valášek, Ondřej ; Pruša, Radomír (referee) ; Huzlík, Rostislav (advisor)
The thesis deals with the development and implementation of a PLC program in a workplace for dynamic loading of electric drives. Initially, an analysis of the dynamics of electric drives is performed, including the principle of operation of permanent magnet synchronous motors. The effects of control and design parameters of the electric motors on the resulting dynamic parameters of the system are then described. The practical part of the work first deals with the recovery of the workstation for operation in manual mode in order to determine the important parameters for the operation of the inverter in the dynamic brake mode. Based on the obtained variable parameters, a control program is developed and soon implemented in the PLC. The designed program is then verified by loading the DC motor in both speed and torque loop with constant and variable parameter change time. The data from the validation tests are evaluated and displayed in graphs that describe the measurement outputs. Finally, recommendations for workplace optimization are given. A manual for operating the workstation and controlling it from the user interface in Connect is included.

Bus wiring systems for complex building management
Mokrý, Lukáš ; Macháček, Jan (referee) ; Bátora, Branislav (advisor)
The aim of my thesis is to examine current opportunities of bus wiring systems for complex building management, mainly its power and economic evaluation. It can be simply called intelligent electrical installation. I will examine two systems from INELS and ABB company. These systems contain functional components, mainly modules and controllers. By means of other materials, I’ll create a panel. Components will be placed there and electrically connected. After this, systems will be put into operation and programmed by means of their software. The next step is measuring of quatities during the various conditions of systems and consumption, which is one of the main aims of the thesis. Two apparatuses will be used for measuring. This thesis itself will contain theoretical analysis of systems, their description, using the way of operation and main advantages and disadvantages. Single components and complete process of measuring and working in laboratory will be described. An overall evaluation and comparison of the systems from various points of view, including the price, will be put together from results.
