Abstract

In this paper the three-phase voltage asymmetry influence on mechanical characteristics of asynchronous motors is analyzed. The magnitudes required to calculate the relative values of the selected rotor slip torques according to Kloss formulas (critical slip sc, coefficients, exponent indexes) are determined according to the rated parameters of asynchronous motor. The motor torques estimated in the slip ranges 0

Abstract

The article analyzes energy supply alternatives for modernised public nearly zero energy buildings. The paper examines alternative energy production systems such as heat pumps (air-water and ground-water), solar collectors, adsorption cooling, biomass boiler, solar photovoltaic, wind turbines and combinations of these systems. The simulation of the analysed building energy demand for different energy production alternatives has been performed using TRNSYS modelling software. In order to determine an optimal energy supply variant, the estimated results of energy, environmental, and economic evaluation have been converted into non-dimensional variables (3E) using multi-criteria analysis.

Abstract

Siekiant patenkinti vis didėjantį energijos poreikį, visame pasaulyje intensyviai ieškoma naujų, ekologiškų technologinių sprendimų, kaip padidinti esamų energijos konversijos sistemų efektyvumą ir naujų energijos nešėjų, kurie jau artimiausioje ateityje iš dalies pakeistų egzistuojančius energijos šaltinius. Vienas perspektyviausių mokslinių pasiūlymų šioms problemoms spręsti yra vandenilio energetikos technologijų panaudojimas. Straipsnyje pateikti atlikti 125 kW kietojo oksido kuro elemento pagrindinių sąnaudų skaičiavimai. Reikalingų sąnaudų apskaičiavimas turi ekonominę reikšmę parenkant kuro elementų sistemas. Future alternatives must be developed for long-term and environment- friendly energy supply needed by the constantly growing world’s population. Electrical-generation efficiencies of 70% are possible nowadays, along with heat recovery possibility. Fuel cells appear to be an important technology for the future. They can run on a variety of fuels, from solar hydrogen to methanol, from biomass to gasified coal. As the technology develops, and if the cost of fossil fuels continues to rise, this clean, efficient alternative will find more and more practical uses. The paper discusses stationary applications of the Solid Oxide Fuel Cells system. Fuel, oxygen and produced energy calculations are presented. С каждым годом в мире возрастает потребность в энергет��ческих ресурсах. Интенсивно исследуются возможности повысить эффективность существующих энергетических систем и новые энергоносители, которые не нарушали бы природный баланс и заменили бы нефтепродукты. Одно из самых перспективных предложений в этой области – применение водородной энергетики. В настоящей статье дана оценка затрат для высокотемпературного топливного элемента мощностью 125 кВт. Эти подсчеты имеют экономическое значение при подборе и применении топливных элементов.
