Power Systems Ranges of Main Parameters
Řehořek, Tomáš ; Gála, Michal (referee) ; Paar, Martin (advisor)
The thesis deals with description of the power system, parameters of it’s components and the range of outputs and consumption. In the first part the structure of the power system is described as well as the fundamental division of electric grids. In this part the work also touches on the ways of supllying the elctric traction. Furthermore the amount of production and consumption is mentioned. In the second part this work focuses on description of selected components of the power system and their real parameters. Furthermore the work also touches on the matter of electromobility and battery energy storage systems. In the last part of this work a few simple methods of consumption estimation are presented. This work also includes two infografics, that describe the power system.
Telemetry and Dispatch Control of Low Voltage Grid
Gála, Michal ; Vaculík, Petr (referee) ; Toman, Petr (advisor)
The contents of this thesis are the introduction to mesh grids, the method of dispatch control of these grids and the description of technology used in mesh grids distribution nodes in the city of Brno. This thesis also describes low voltage switchgears used in these types of grids. The development of dispatch control in ECD company is also mentioned. The development describes the grid dispatch control methods prior to implementing the OMS system and the changes which followed after the implementation. The process improvements of the new system resulting from this thesis can be found in this thesis as well. The improvements are incorporated in the OMS system and are used for more efficient dispatch control of the low voltage mesh grids. There is a more detailed analysis of the mesh grid Brno – Bohunice in the practical part of this thesis. The practical part contains analyses of mesh grids stabilized conditions measurements and analyses of mesh grids fault conditions measurements. The analyses assess the power load in transformers, minimal and maximal phase current and maximal power load at the time they were observed. The analysis of the measured data is accompanied by the assessment of differences in current phase measurements and differences in voltage phase and combined measurements. The result, based on the analysis and collection of the data, is a proposition of adding switchgears for the support of the dispatch control of the mesh grid Brno – Bohunice. In the summary of the thesis there is a comparison of the result of the factual and theoretical analysis. An experimental model of the mesh grid Brno – Bohunice was created in PS CAD software as a part of the theoretical analysis.
