Nuclear Power Plant Dukovany Tasks within an Electricity Grid of the Czech Republic
Prokop, Ondřej ; Řež,, Martina Malá, Centrum výzkumu (referee) ; Katovský, Karel (advisor)
The aim of the Bachelor’s thesis is to describe the role of The Nuclear Power Plant Dukovany (Dukovany NPP) in the Czech electricity grid. Increasing of the production of electricity from renewable energy sources in the electricity grid causes more frequently compliance of N-1 criterion and it decrease the reliability of the electricity grid. The risk of Blackout increases, which would cause large economic losses and danger to the life of human beings. Therefore, reliable, good controllable and safety sources of electricity are very important. The first part of the thesis describes the role of Dukovany NPP in the process of regulation of basic electrical parameters during the normal operation of electricity grid. The second part of the thesis deals with states and the function of Dukovany NPP after full or partial disintegration of the electricity grid. Final part analyzes the importance of Dukovany NPP in Czech electricity grid and future development Dukovany NPP with possibility of the construction of new nuclear units after the end of the operation in 2035. The Dukovany NPP is an important regulator of the reactive power. There isn’t other power plant in the southeastern part of the Czech Republic, which could significantly control reactive power. The power from Dukovany NPP, which is provided on ancillary services controlling the real power and frequency has been increasing in recent years. This is due to the increasing production of renewable sources. Units switch to island operation after partial disintegration of electricity grid. If frequency exceeds the limit, the units will switch to it is own consumption. In this stage of operation at own consumption can Dukovany NPP operated without the time limit. Dukovany NPP may participate in restoring the electricity grid, based on dispatch control instruct. If switching to own consumption is not successful and back up sources and emergency’s dieselgenerator are unavailable, the power supply has to be restored as soon as possible. There are six independent solutions to restore the power supply. Next option of restore power supply will be the AAC network after the completion of construction in 2014. The AAC network will be resistant to the extreme weather and will be place it in the area of the power station, thereby Dukovany NPP will be more independent on external network.

Starting the electricity system from the dark with the help of EDU
Puchnar, Jiří ; Fejta, Libor (referee) ; Mastný, Petr (advisor)
This bachelor thesis aims to introduce the reader Blackout exercise, which is run annually on nuclear power plant Dukovany. This exercise simulates a situation when there is a loss of power for own consumption and the steps leading to its recovery. Then it focuses how to troubleshoot electrical grid restoration of the Czech Republic with NPPD. This bachelor thesis is divided into two parts. The first part defines the term Blackout, described the involvement of power plant to national grid, output to a substation Slavětice and near power sources. NPPD appliances are divided into categories according to the importance of power. Their classification and ways of feeding during normal operation and for other situations are described in the third chapter of this work. In my work I present options and recovery routes after power failure for own consumption NPPD. Internal and external. The lack of power can cause the risks described in the fifth chapter. At the end of the first part is an example of one possible method to restore power from an external source. The second part focuses on the renewal of electrical grid with NPPD. It aims to describe the configuration of the transmission system, using of island operation and some specific features related to island operation. In this section, I present also some new possibilities for increase of durability and safety of electrical grid CR NPPD. The conclusion summarizes the meaning of Blackout exercise together with the benefits of this work and some recommendations.
