20.500.12556/DKUM-77780 Ocenjevanje vztrajnostne konstante EES diplomsko delo Inertia estimation of an electric power system Diplomska naloga obravnava vztrajnost elektroenergetskega sistema (EES). Opravljena je analiza obnašanja EES ob upadu frekvence iz katere sledi, da je gradient frekvence odvi-sen od vztrajnosti EES. Obravnavani so algoritmi za ocenjevanje vztrajnosti na osnovi li-nearnega diferencialnega operatorja in linearnega integralnega operatorja v kombinaciji z metodo najmanjših kvadratov. Narejeni so simulacijski izračuni z uporabo poenostavlje-nih modelov agregatov in z uporabo popolnega modela hidroelektrarn Vuhred in Ožbalt. Nakazana je tudi problematika vpliva vetrnih elektrarn na vztrajnost EES. Rezultati kažejo na negativni vpliv nemodelirane dinamike in meritve frekvence pri uporabi obravnavanih algoritmov. The diploma thesis deals with the inertia of the electric power system. An analysis of the behavior of the power system with a decrease in frequency is performed, from which it follows that the rate of change frequency depends on the inertia of the power system. Algorithms for estimating inertia based on a linear differential operator and a linear in-tegral operator in combination with the least squares method are discussed. Simulation calculations are made using simplified models of aggregates and using a complete model of Vuhred and Ožbalt hydropower plants. The issue of the influence of wind power plants on the inertia of the power system is also pointed out. The results show a negative influ-ence of the unmodeled dynamics and frequency measurement method when using the considered algorithms frekvenca vztrajnostna konstanta ocenjevanje vztrajnosti frekvenčna stabilnost pomično podatkovno okno Frequency inertia constant estimation inertia frequency stability moving data window true true false [B.
