Abstract
Diplomska naloga opisuje avtonomno napajanje stanovanjske hiše iz obnovljivih virov in/ali z generatorjem v primeru daljšega izpada napajanja iz omrežja. V teoretičnem delu smo podrobneje definirali delovanje samostojnega otočnega solarnega sistema (sestavni deli solarnega sistema so: fotonapetostni modul, akumulatorji, regulatorji, razsmerniki, porabniki), prednosti in slabosti omenjenega sistema, pregled in primeri cen kompletov za solarni sistem ter opis agregatov. V praktičnem delu smo predstavili primer napajanja plinske peči z agregatom. Pri priključitvi na omrežje je plinska peč obratovala normalno, pri priključitvi na agregat (preizkušenih je bilo več agregatov) je nekaj sekund po zagonu prišlo do izključitve peči. Sledi opis in podrobna razčlemba faze reševanja problema. V tem delu smo se osredotočili na meritve napetosti agregata ter izračune padcev napetosti (na koncih podaljškov, na ohmski upornosti navitja ločilnega transformatorja, kablu plinske peči ter hladilnikov). V nadaljevanju smo predstavili rezultate, s katerimi smo zapisali sklep celotnega primera.

Title:AUTONOMOUS SUPPLY OF A HOUSE WITH SOLAR POWER PLANT AND PORTABLE GENERATOR
Abstract:
This B.Sc. dissertation describes autonomous power supply of a house from renewable sources of energy and/or with a portable generator in case of longer power outage. In the theoretical part, we analysed in detail the working of a standalone solar system (parts of the solar system: solar module, battery, grid inverter, ac loads), the pros and cons of the mentioned system, the overview and comparison of prices for solar system and the description of generators. In the practical part, we presented an example of supplying a gas heater with a portable generator. When plugged into the electrical grid, the gas heater worked normally, but when it was plugged into the generator (we tested a number of them) it shut down a few seconds after starting. What follows is a description and detailed analysis of the phases of solving the problem. In this part, we focused on measuring the generator voltages and calculating voltage drops (at the ends of electrical extensions, at ohmic resistance of the winding of isolation transformer, cable of gas heater and cooling systems). At the end, we presented results with which we came to the conclusion of the whole case.

Keywords:Keywords: gas heater, solar system, generator, auxiliary power grid
