Abstract
Na početku ovog rada opisan je matematički model stabilnosti kuta rotora i napona u prijenosnoj mreži. U teoretskoj obradi također ja kao nužnost obrađen rad i primjena elektroničkih energetskih pretvarača koji su temelj HVDC veze LCC tipa koja je predmet istraživanja diplomskog rada. Praktični dio rada sastoji se od podešenja parametara HVDC sustava i njegove integracije u 345-kV prijenosnu mrežu te analize utjecaja na pokazatelje stabilnosti sustava. Uz same pretvarače su, kao dio sustava, implementirane i reaktivne komponente i pasivni filtri kao mjera poboljšanja harmonijskog spektra struja i napona. Nakon utvrđivanja ispunjenosti načela kvalitete električne energije, provedene su simulacije za analizu tranzijentne i oscilatorne stabilnosti. Utjecaj na tranzijentnu stabilnost promatrao se kroz odziv sustava na veliki poremećaj (trofazni kratki spoj na sabirnici) s naglaskom na određivanje kritičnog vremena čišćenja. Pokazatelji oscilatorne stabilnosti vrednovani su u s- i t-domeni tako da su analizirani položaj svojstvenih vrijednosti u kompleksnoj ravnini i dinamički odzivi sinkronih generatora na mali poremećaj (promjena opterećenja). Na kraju su generirane PV krivulje kako bi se provela procjena utjecaja HVDC-a na naponske prilike u sustavu i stabilnost napona. .
Abstract (english)
This paper begins by describing a mathematical model for rotor angle stability and voltage stability in the transmission network. In the theoretical section, the work also addresses the necessity and application of power electronics converters, which are fundamental to the LCCtype HVDC link, the subject of this thesis. The practical aspect of paper involves the adjustment of HVDC system parameters and its integration into the 345-kV transmission network, folowed by an analysis of its impact on power system stability indicators. In addition to the converters, reactive components and passive filters have been implemented as part of the system to improve the harmonic spectrum of currents and voltages. After ensuring compliance with power quality standards, simulations were conducted to analyze transient and small-signal stability. The impact on transient stability was observed through the system's response to a major disturbance (a three-phase short circuit on the busbar), with an emphasis on determining the critical clearing time. Indicators of small-signal stability were evaluated in the s- and tdomains by analyzing the position of eigenvalues in the complex plane and the dynamic responses of synchronous generators to a small disturbance (load change). Ultimately, PV curves were generated to asses the influence of the HVDC on voltage conditions and stability of the system.
