<p dir="ltr">A broad scope of this dissertation is to verify that a nearby loss of generation event in power system can be distinguished from similar remote disturbances by analyzing the resulting local modes of oscillation. An oscillation-based index derived from methods like Fourier transform, sinc filters and resonant filters is devised and experimented in combination with a variant of df/dt index to jointly classify if a loss of generation event is nearby or remote. A phenomenon widely observed during a loss of generation event is the average decrease in the system’s frequency, typically monitored using the df/dt index. Under-frequency load-shedding (UFLS) relays that are based on df/dt are highly likely to trip for nearby frequency events when combined with the oscillation-based index we propose. Nearby in our context refers to geographical distance, which is correlated with electrical distance, and includes buses within about 50-100 miles of the event location.</p>

The preparation of campaign promoting autonomous detection and signaling devices within activities of preventive education in section of fire protection We can come across fires of buildings designed for living every day, therefore is very important to try to prevent them. The most accessible way is the installation of autonomous detection and signaling devices, which is currently obligatory to all newly designed and built houses. These devices detect emerging fire, subsequently inform about possible threat and at the same time they allow enough time for the population rescue. To achieve the main aims of thesis, it was needed to study specialized literature and write theoretical part which explains basic concepts connected to the topic, defines the dangers in the place of fire, followed by classification of toxic substances which are released during the fire and finally describes autonomous detection and signaling devices. The integral part contains the graphic layouts focused on the comparison of statistical data from 2001 till 2011, mostly tracking fires and number of killed and injured people during the household fires, which is compared to the number of killed and injured people and fires in general. There was made questionnaire for 50 public respondents from the city Zábřeh after completing the theoretical part. These respondents were chosen on purpose in cooperation with the fire station Zábřeh, which is part of Fire Rescue Service of Olomouc district. We defined hypothesis: The knowledge of Zábřeh population about own life and property protection against the fire are insufficient. The hypothesis was defined using descriptive and mathematical statistics. However, our hypothesis wasn´t confirmed so we can consider awareness of Zábřeh population to be sufficient but not excellent. Therefore, there is still need to increase their legal responsibility. The practical part further includes the analysis of questionnaire answers, which is aimed to evaluate the accuracy of answered questions. Last but not least, the thesis presents the set of promotional campaigns which are ordered by the ability to properly effect on the population via web pages, daily press, TV broadcast or printed materials. The most wanted way would be TV campaign, which is unfortunately expensive and time-consuming; therefore, it seems to be the best option to create web pages or printed material aimed for general public. The both promotional campaigns should be provided by Ministry of the Interior - general directorate of Fire Rescue Service of Czech Republic.
