magistrsko delo
Povzetek
Magistrsko delo opisuje stanje elektroenergetskega omrežja v podjetju, ki se ukvarja z jeklarsko industrijo. Problematika, elektroenergetskega omrežja so motnje, ki jih naprave vnašajo v sistem in zaradi tega močno motijo delovanje občutljivih in kompleksnih krmilnih sistemov, kar privede do mnogih nepotrebnih izpadov. Nadalje naprave z njihovim delovanjem slabšajo prenosne zmogljivosti prenosnih vodov, porabljajo veliko jalove energije, faktor delavnosti pa je zaradi tega slabši. Motnje ne samo močno vplivajo na zanesljivost delovanja elektroenergetskega sistema podjetja, marveč motijo celotno regijo, vplivajo na finančne kazalnike podjetja, ter ne nazadnje, če amplituda motenj ni sanirana ter v mejah tolerance, nas lahko distributer električne energije zaradi nedoseganja standardov finančno kaznuje.
Magistrsko delo po logičnem zaporedju prikazuje, kako in s čim motnje kar se da v največji meri odpraviti. Za to je potrebna seveda v prvi vrsti intenzivna in natančna analiza razmer v elektroenergetskem sistemu podjetja, na podlagi dobljenih rezultatov pa poiskati rešitve, ki so tako tehnično kot tudi finančno sprejemljive za lastnika na eni strani ter distributerja na drugi strani. Raziskovalno delo torej poda tehnične rešitve, ki so na eni strani že dobro raziskane in uveljavljene, ter na drugi strani predstav novitete na področju energetskih omrežij tudi s stališča aktivnih kompenzacij.

Reliability of Power distribution system with a focus on active compensation devices |
Sekundarni povzetek: |
Master's thesis describes the state of the electricity grid in a company, which is engaged in the steel industry. The problem of the electricity grid are disturbances entered into the system by equipment and therefore greatly disturb peration of sensitive and complex control systems, which leads to many unnecessary blackouts and malfunctions. Furthermore, devices with their operations deteriorate transmission capacities of transmission lines, consume a lot of reactive power and the power factor is therefore worse. Disorders not only severely affect the reliability of the company's electricity system, but disturb the whole region, affect the financial indicators of the company, and last but not least, if the amplitude of the interferences cannot be rehabilitated and within the limits of tolerance, electricity distributor may impose financial penalties due to our failure of reaching the set standards.
Master's thesis shows by a logical sequence how and what with can such disorders be largely eliminated. This requires, of course, first and foremost intensive and detailed analysis of the situation in the company's electricity system, and based on the results obtained, however, to find solutions that are both technically and financially acceptable to the owner on the one hand and to the distributor on the other. Research therefore proposes technical solutions that are on the one hand already well-researched and well-established, and on the other hand shows innovations in the field of energy networks and active compensators. |
