Uninterruptible power supply
Podal, Pavel ; Rampl, Ivan (referee) ; Chmelař, Milan (advisor)
The objective of this work is to inform readers on classification of Uninterruptible Power Supply (UPS). depending on the equipment for which is to be used. Voltage quality has a decisive influence on the operation of equipment. There are various common power problems that UPS units are used to eliminate. Furthermore, I described backup power sources of energy used for UPS, in partikular secondary battery. This text is about UPS technology used for critical applications, witch must not fail due to a power outage or other power anomalies too.

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.

Providing emergency supply of nuclear power plants
ROZMILER, Jiří
Work "Providing emergency power nuclear power plant" describes how solving their own consumption nuclear power plant, as emergency power supply is designed and how it should be a solution of known states of emergency, having an immediate impact on the power consumption of their own nuclear power plants. The aim of this thesis is to propose options to strengthen its own emergency power consumption of nuclear power plants, one might say-more resistant to harsh extremes, which could lead to loss of employment, reserve and emergency power, that is the condition called Station Black Out (SBO) - total loss of power. The work also includes calculations of short-circuit ratios emergency resources considered as strengthening, as well as the calculation of acceleration heaviest drive and a summary of the overall impacts of the proposed hardening.
