A power network analyzer SW upgrade implementing LV PFC capacitors bank design on the basis of measurement
Bernáth, František ; Pospíchal, Ladislav (referee) ; Drápela, Jiří (advisor)
Thesis is devoted to a problem of Power Factor Correction on the low voltage level. It has still its own difficulties despite the fact that topic moved through long development. The main goal of this work is to offer reader variable procedure considering design process. It is based on use of measured data of network analyzer Meg30. The design algorithm has to share a maximum of eventual influencing factors. Therefore the body of master thesis goes through detailed analysis of Power Factor Correction.
Change of voltage at LV terminals of a MV/LV power distribution transformer caused by changes in its load
Bernáth, František ; Špaček, Jaroslav (referee) ; Blažek, Vladimír (advisor)
This thesis is devoted to topic of distribution transformers. In the first part of text there are mentioned theoretical knowledge which prepare basement for solving model situation in electric network. The industrial park is plugged by three transformers and we are interested in change of voltage at LV terminals of transformers according its load. Solving of example will include counting Blondel’s constancies of chosen substitute circuit.
Distributed Generation and its Influence on Power Quality
Bernáth, František ; Santarius, Pavel (referee) ; Braciník,, Peter (referee) ; Mastný, Petr (advisor)
This work deals with the deployment of distributed power sources into the electric power grid. The nature of these sources causes that the massive integration may experience problems with power quality in the local context, and also overall reliability of supply in the range of interconnected power systems may be endangered. Work is focused on local voltage quality problems with special emphasis on analysis and design of tools (e.g. reactive power compensation units of power plants or dynamic voltage control by transformers 110/22kV) for voltage control in power distribution systems. These tools should be used as a part of uniform concept of voltage control. The proposed concept is involved.
