20.500.12556/RUL-91827 NADGRADNJA MODELA DVOJNO NAPAJANEGA STROJA V ČRPALNIH HIDROELEKTRARNAH UPGRADING OF MODEL OF DOUBLY-FED MACHINE IN PUMP-STORAGE PLANTS Magistrska naloga opisuje poskus poustvarjanja modela črpalne hidroelektrarne (ČHE) z vgrajenim dvojno napajanim indukcijskim strojem (angl. DFM – doubly-fed machine) s spremenljivo hitrostjo vrtenja. V Sloveniji in po svetu se gradi vedno več takšnih elektrarn in njihov vpliv na omrežje nikakor ni zanemarljiv. Zaradi tega je za potrebe dinamičnih analiz nujno potreben ustrezen model, ki bi se dodobra približal realnemu stanju v omrežju. Model, opisan v tem delu je povzet iz tuje literature in prilagojen za programsko okolje PSS®NETOMAC, v katerem smo model izdelali in analizirali. V literaturi je bil model predstavljen zgolj shematično s skopimi opisi, zato smo morali določene elemente prirediti po svoje. V delu se najprej posvečamo izvoru modela in osnovam dvojno napajanih strojev. Nato je predstavljen in opisan prirejen model, primeren za vnos v PSS®NETOMAC. Model smo izdelali in preizkusili na sistemu generator/motor - toga mreža (angl. SMIB – Single-machine infinite-bus). V zadnjem delu so predstavljeni rezultati, kako se model odziva na različne motnje. This thesis describes development of adjustable speed pumped-storage hydro unit (AS PSH) employing a doubly-fed machine (DFM). Several new units are built in the world and their impact on the electric-power system cannot be neglected. This was the main reason for developing a model appropriate for dynamic analyses. Model used in this thesis is taken from a report prepared by U.S. Department Of Energy. The model is slightly modified in this thesis in a way that can be used in PSS®NETOMAC. First, the thesis covers the origins of the model. Furthermore the thesis includes demonstration and description of the new modified model suitable for PSS®NETOMAC. The modified model was built and tested on a SMIB (Single-machine infinite-bus) system. The last part of the thesis presents the results of the testing with various faults in the system. črpalna hidroelektrarna dvojno napajan stroj model PSS®NETOMAC dinamična analiza pumped-storage hydro plant doubly-fed machine simulation model PSS®NETOMAC dynamic analyses true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2017-04-21 12:30:14 2017-04-21 12:30:18 2022-08-09 23:13:44 0000-00-00 00:00:00 2017 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 37901 Pesl_Leon_-_NADGRADNJA_MODELA_DVOJNO_NAPAJANEGA_STROJA_V_CRPALNIH_HIDROELEKTRARNAH.pdf Pesl_Leon_-_NADGRADNJA_MODELA_DVOJNO_NAPAJANEGA_STROJA_V_CRPALNIH_HIDROELEKTRARNAH.pdf 1 A8E28386FBDE562DD566D26F51335CC5 22a8aeff7e89c92ba2652d25ce398e6aa823561cb8511be04ea192bf12798501 dd673ff6-a1b2-11eb-a523-00155dcfd717 20.500.12556/rul/4795fbd4-ca6a-4108-b2e3-bac8708d8e5a https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=97903 Fakulteta za elektrotehniko 0 0 0
