Item DAMAGE INFLUENCE OF PV-MODULES ON THE EFFICIENCY OF THEIR WORK(Бургаски свободен университет, 2018) Лецковска, Силвия; Сейменлийски, Камен; Заеров, Елдар; Симионов, РадославThis paper presents some of the methods for testing photovoltaic modules to detect faults and defects in them. There are results from experimental tests for detecting defects in the modules of the photovoltaic plant installed on the roof of Burgas Free University.Item MODERN TECHNOLOGICAL SOLUTIONS IN ELECTRICITY SUPPLY(Бургаски свободен университет, 2018) Сейменлийски, Камен; Лецковска, Симвия; Заеров, Елдар; Симионов, РадославThis paper examines the impact of electrotechnical installations on the environment, in particular the influence of an electromagnetic field, a source of which in the residential buildings are the transformer substations, the distribution boxes for power supply, as well as the conductors from the supply network. Attention is paid to thermal imaging as a modern technological solution that can be successfully applied to the diagnosis of building energy systems.Item АНАЛИЗ НА РАЗВИТИЕТО НА ВЪЗОБНОВЯЕМИ ЕНЕРГИЙНИ ЦЕНТРАЛИ НА БАЗАТА НА ПОТЕНЦИАЛА НА ЕНЕРГИЯТА ОТ МОРСКИТЕ ВЪЛНИ(Бургаски Свободен Университет, 2020) Заеров, Елдар; Лецковска, СилвияThe use of energy from sea and ocean waves is a very promising energy sector, as the potential of the world's oceans is virtually limitless. In this study, the different methods for producing energy from sea and ocean waves are analyzed. Emphasis is placed on the main types of power plants powered by sea waves, the converters of energy from sea waves, the technologies using different converters, the Technical and economic development of WEC systems.Item БУРГАСКИ СВОБОДЕН УНИВЕРСИТЕТ – ПРОИЗВОДИТЕЛ НА ЕНЕРГИЯ(Бургаски свободен университет, 2015) Заеров, Елдар; Сейменлийски, Камен; Лецковска, СилвияIn recent years, with increasing requirements of the European Union for reducing harmful emissions and increasing energy efficiency in public buildings and industrial systems increasingly topical issue is the problem of the generation of electricity from its own power plants using renewable energy sources. The purpose of this work is to present part of the results that the collective has received in studies of the potential for electricity production from the roof of Bourgas Free University.Item ИЗПОЛЗВАНЕ НА ПЕРОВСКИТА В СЛЪНЧЕВАТА ЕНЕРГЕТИКА(Бургаски свободен университет, 2018) Заеров, ЕлдарThe article describes a relatively new material for solar energy - perovskite. There is a description of its physical properties, and the developments in this industry are given by both Russian and foreign scientists. The paper conducted a comparative analysis of the solar cell materials by efficiency.Item ИЗСЛЕДВАНЕ НА ПРОИЗВОДИТЕЛНОСТТА НА МИКРО PV ЦЕНТРАЛИ(Бургаски Свободен Университет, 2020) Сейменлийски, Камен; Лецковска, Силвия; Симионов, Радослав; Заеров, ЕлдарThe report presents the study on the performance of the micro PV central with the same type of photovoltaic panel, but with different conditions.Item ПЕРСПЕКТИВНИ ТЕХНОЛОГИИ ЗА ОПОЛЗОТВОРЯВАНЕ НА МОРСКИЯ РЕСУРС(Бургаски Свободен Университет, 2020) Лецковска, Силвия; Сейменлийски, Камен; Заеров, Елдар; Симионов, РадославThis article discusses the desalination of sea water. The focus is on the use of renewable energy for the desalination of sea water. Existing desalination plants from the Black Sea have been studied.Item ПОВИШАВАНЕ НА ПРОИЗВОДИТЕЛНОСТТА НА СЛЪНЧЕВИ ПАНЕЛИ С ПЛОСКИ РЕФЛЕКТОРИ(Бургаски свободен университет, 2021) Заеров, ЕлдарSolar energy is one of the most significant sources of renewable energy both in its fields of application and in thermal and photovoltaic, all over the world. Bulgaria is one of the countries with an excess of this type of energy, where the annual solar activity on a horizontal surface reaches about 1000 kWh / m 2 / year. In this work, solar collectors with a V-shaped trough of a concentrator system with two geometric concentrations are designed to obtain additional electric power. The main results show that the solar concentrator system causes an increase in short circuit current due to an increase in the amount of incident solar radiation from the solar modules and, consequently, an increase in the output power. Compared to the reference module, the increase in power during peak hours exceeds 40%. It can be concluded that the use of a V-Trough concentrating system in combination with modular solar systems can lead to a favorable price-benefit ratio.Item ПРОИЗВОДИТЕЛНОСТ И ЕНЕРГИЙНА ЕФЕКТИВНОСТ НА RASPBERRY PI БАЗИРАН КОМПЮТЪРЕН КЛЪСТЕР(Бургаски свободен университет, 2022) Моллова, Стоянка; Лецковска, Силвия; Орешков, Кольо; Заеров, Елдар; Лодкаджиев, КристиянA cluster structure of single-board Raspberry Pi microcomputers has been implemented. Laboratory studies and analysis of performance and energy efficiency characteristics for the created cluster have been carried out.Item СИСТЕМА ЗА ВИЗУАЛИЗАЦИЯ НА ДАННИ ОТ ЕНЕРГИЕН ТРЕНИРОВЪЧЕН(Бургаски свободен университет, 2019) Сейменлийски, Камен; Лецковска, Силвия; Заеров, Елдар; Симионов, РадославТази статия представя опита на Бургаския свободен университет в изграждането на интелигентна учебна среда в областта на възобновяемата енергия, която да се интегрира в системата за електронно обучение. Учебната среда включва използването на интелигентни устройства за наблюдение и управление на две фотоволтаични централи, използващи сложна метеорологична станция.Item СЪДЕБНИ ТЕХНИЧЕСКИ ЕКСПЕРТИЗИ НА iOS МОБИЛНИ УСТРОЙСТВА(Бургаски Свободен Университет, 2022) Лецковска, Силвия; Сейменлийски, Камен; Рачев, Георги; Заеров, ЕлдарThe mobile device is now a part of our life and is a huge repository that stores sensitive and personal information about its owner. Because of this, mobile devices have become an object of study in forensics. A branch of digital forensics has been created that deals with the extraction of data from a mobile device. The aim of the present study is to investigate the methodology for extracting information from a digital device without changing the data present on it.Item ТЕОРЕТИЧЕН ХИБРИДЕН МОДЕЛ ЗА ДОБИВ НА СЛАДКА ЧЕРНОМОРСКА ВОДА(Бургаски свободен университет, 2021) Градинарова, Полина; Заеров, ЕлдарThe main purpose of this report is to present a theoretical hybrid model for seawater desalination including a photovoltaic plant and salt pans as a source of seawater in a closed production cycle.
