20.500.12556/RUL-84921 Valovni lokator okvare Travelling wave fault locator Delo se nanaša na izdelavo preprostega algoritma za izračun razdalje do mesta okvare na daljnovodu, ki je del valovnega lokatorja okvare. Namen naloge je bil raziskati princip delovanja valovnega lokatorja okvare, izdelati svoj algoritem za izračun razdalje do mesta okvare in preveriti njegovo delovanje s pomočjo simulacij. Izračuni in simulacije so bili izvedeni v Matlabu v povezavi s Simulinkom. Algoritem je bil izdelan za tri metode, ki jih valovni lokator okvare lahko uporablja. Širše uporabna, dvostranska metoda D se je izkazala za zelo dobro in natančno. Izračuni so dosegli zadovoljivo natančnost, pričakovano s teoretičnega vidika. Simulacije so pokazale tudi možnost praktične uporabe algoritma pri določanju razdalje do mesta okvare. Enostranski metodi A in E sta podali rezultate pričakovane točnosti, ki pa za praktično uporabo ne bi bili zadovoljivi. The subject of this thesis is algorithmic calculation of line fault location, using the travelling wave fault locators. The scope was to research the principle behind travelling wave fault locators, as well as to propose an algorithm for calculation of distance to the fault location, followed by a demonstration of the feasibility of the algorithm through simulations. All the calculations and simulations were executed with the program packages Matlab and Simulink. Three different methods were applied and tested. The application of the two-sided method D had the best results in terms of theoretically acceptable accuracy. The simulations have demonstrated the practical applicability of the method. One-sided methods A and E resulted in accuracy within the expected range, that is not suitable for practical applications. valovni lokator okvare potujoči valovi odboj valov travelling wave fault locator travelling waves wave reflection true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2016-09-08 14:15:01 2016-09-08 14:15:03 2022-08-02 06:39:33 0000-00-00 00:00:00 2016 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 36224 Podgrajsek_Martin_-_Valovni_lokator_okvare.pdf Podgrajsek_Martin_-_Valovni_lokator_okvare.pdf 1 23715AB7DD7F0C8EBF6CB6B5F9DB1252 88503b5992fc950e373025070ac1460223cf8234069f57cf02b22c32d070c7f7 eec4d5a1-a1b0-11eb-a523-00155dcfd717 20.500.12556/rul/ce6ec148-155a-4f22-a045-b3f392452f95 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=88039 Fakulteta za elektrotehniko 0 0 0
