Visualization and online control of important parameters of block and tap-changing transformers at the Dukovany nuclear power plant
Holeš, David ; Mareček, Oto (referee) ; Mastný, Petr (advisor)
The thesis focuses on a design of visualization and setting limits of important parametres of power and own-consumption transformers at the nuclear power plant Dukovany. In the first part there is a description of a present technical state of oil power transformers at this power plant, including a description of a currently installed transformers monitoring system and electro monitoring system. The second part deals with a design of a visialization of parametrs and a diagram design of active-access displays of monitored parametrs of these transformers. In the thesis there is also a description of web interface with a new visualization. The last part of the thesis contains a design of setting the limits and criteria of important monitoring parametres of these transformers.

Verification and modification of differential modules algorithms of automatics "Emergency Load Sequencer" and "Back-up Emergency Switching" of the nuclear power plant Temelín
Šula, Vladimír ; Mareček, Oto (referee) ; Toman, Petr (advisor)
This paper's objective is to describe necessary changes in the database of measured signals at Temelín Nuclear Power Station caused by an investment action. The changes were essential as the action included a replacement of an outdated analog protection system with new microprocessor terminals. The paper also describes changes of reference modules algorithms, which are used for tests and experiments of APS and AZR automatic systems. This paper can be divided into a theoretical part and a practical part. The theoretical part concerns issues connected with output extraction and Temelin's own consumption feed. Next, it concerns an actual explanation and description of APS and AZR automatic systems, LOGA software and MOSAD®-5 monitoring system. The practical part includes a list of actual changes that had to be made in connection with the change of the protection system. The performed changes concerning the reference modules are tested using imitated signals and, subsequently, undergo a full test of automatic systems, which demonstrates correct functionality of reference modules.
