20.500.12556/RUL-110051 DIMENZIONIRANJE NAPAJANJA TRANSPORTA STRANSKIH PRODUKTOV TERMOELEKTRARNE POWER SUPPLY DIMENSIONING FOR TRANSPORTATION OF BY-PRODUCTS IN THERMAL POWER PLANTS Za nemoteno delovanje termoelektrarne je med drugim nujno potreben tudi odvoz stranskih produktov, ki nastajajo ob izgorevanju premoga in prečiščevanju dimnih plinov. V nalogi je predstavljen primer odvažanja produktov z gumijastimi trakovi, ki jih poganjamo z električnimi motorji. Zaradi obsežnosti sistema transporta je napajanje izvedeno preko transformatorjev iz srednje napetosti 6,3 kV na nizko napetost 0,4 kV. Za sistem je bilo potrebno izbrati in določiti vse napajalne kable ter posamezne zaščite porabnikov. Pri dimenzioniranju se moramo držati določenih standardov, ki so opisani v nalogi. Na začetku spoznamo, kaj standardi pravzaprav so in kako nastanejo, kasneje pa lahko preberemo tudi kratke opise tistih, ki so pomembni pri dimenzioniranju nizkonapetostnih inštalacij. Sledi opis projektiranja nizkonapetostne inštalacije, nato pa postopek dimenzioniranja z vsemi pogoji in enačbami, s katerimi pridemo do pravilnih rezultatov. V zadnjem delu je opisan dejanski sistem transporta, za katerega je bilo potrebno dimenzionirati kable in zaščite, temu pa sledijo dejanski izračuni za ta projekt, izvedeni v tabeli, na koncu pa še opis in prikaz računalniške simulacije sistema električne inštalacije. For thermal power plant to operate without any interference it is absolutely necessary to dispose by-products which are created by combustion of coal and filtering flue gases. In this paper the dispose of by-products is presented with rubber belt conveyors which are operated with electric motors. These motors and other consumers are powered through transformers from medium voltage 6,3 kV to low voltage 0,4 kV because of the scale of the system. Power cables and electric protection were needed to be chosen. In dimensioning we have to stick to some standards which are described in this paper. At the beginning we get to know what standards actually are and how they are made, then we can also read short descriptions of standards which are important for dimensioning low voltage installations. This is followed by description of designing low voltage installations, then the dimensioning process with all conditions and equations is provided with which we come to correct results. The actual transport system for which the designing of installations and choice of electrical protection was needed is described in the last part. Description is then followed by actual calculations for this project made in table and at the end there is a description and display of computer simulation of electrical installation. standardi termoelektrarne stranski produkti dimenzioniranje projektiranje nizkonapetostne inštalacije izračuni simulacija standards thermal power plants by-products dimensioning designing low voltage installations calculations simulation true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2019-09-11 13:40:12 2019-09-11 13:40:16 2022-08-22 03:41:20 0000-00-00 00:00:00 2019 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 46681 Kink_Gasper_-_DIMENZIONIRANJE_NAPAJANJA_TRANSPORTA_STRANSKIH_PRODUKTOV_TERMOELEKTRARNE.pdf Kink_Gasper_-_DIMENZIONIRANJE_NAPAJANJA_TRANSPORTA_STRANSKIH_PRODUKTOV_TERMOELEKTRARNE.pdf 1 7DAC64FAB0AEE2A9EF5EFCA30B45E2CE ed48c8151c128ee79ec198bbcd2552e07cf5058c898ccd83998b9577d8c1f3e7 0571a89a-a1b7-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=121670 Fakulteta za elektrotehniko 0 0 0
