Abstract
isokonaponske istosmjerne (HVDC) mreže koriste istosmjernu struju za prijenos elektricˇne energije u elektroenergetskom sustavu. HVDC mreže odlikuju se smanjenim gubicima prijenosa u odnosu na uobicˇajene izmjenicˇne (AC) mreže koje koriste izmjenicˇnu struju i rade na manjim naponima. U okviru ovoga rada, a primjenom znanja iz teorije sustava, analizirani su razlicˇiti opisi i strukture upravljanja point-to-point te umreženih HVDC mreža. U tu je svrhu adaptiran poznati pristup iz teorije sustava za opis dinamicˇkih AC mreža te optimalni LQR problem. Kako bi se upravljanje svelo u okvire prakticˇne uporabe, korištena je metoda redukcije mjerenja. Iako nedavna istraživanja pokazuju povec ́ani interes za modularne topologije naponskih pretvaracˇa, ovakva vrsta ponašanja terminala, kao i strukturnog odabira parametara regulatora, tek je sada, po prvi puta, uklopljena u postojec ́i razvojni okvir mrežnih sustava.
Abstract (english)
A high-voltage direct current (HVDC) electric power transmission system uses direct current for the transmission of electrical power. For long-distance transmission, HVDC systems show lower electrical losses compared to the more common alternating current (AC) systems. Within this work different approaches to describe and control point-to-point and meshed HVDC networks were evaluated. This was realized by adapting a system-thoretical approach initially designed to describe dynamic AC grids, as well as optimal LQR problem. Measurement reduction method was then used, so a practical control solution could be realized. While recent developments show an increased interest in modular voltage source converter topologies, this kind of terminal behaviour, as well as a structured controller parameter selection, was now, for the first time, implemented within the developed framework.
