Large interconnected power systems often suffer weakly damped swings between synchronous generators and subsystems. This paper presents an approach, based on the use of non-linear system model and application of the direct Lyapunov method, to improve damping of power swings using the Unified Power Flow Controller (UPFC). State-variable control strategy has been derived as well as its implementation utilising locally available signals of active and reactive power. Finally results of simulation tests undertaken on a small multi-machine system have been shown.

W artykule przedstawione zostało wyprowadzenie algorytmu sterowania elementu UPFC (z uwzględnieniem sterowania części bocznikowej i szeregowej). Algorytm ten został wyprowadzony dla modelu nieliniowego systemu elektroenergetycznego korzystając z bezpośredniej metody Lapunowa. Na podstawie optymalnego algorytmu sterowania opartego na sygnałach zmiennych stanu (delta, omega)) autorzy zaproponowali zastosowanie sygnałów mierzalnych lokalnie, mocy czynnej i biernej. Opracowane algorytmy korzystające z sygnałów mierzalnych lokalnie zostały sprawdzone symulacyjnie na modelu wielomaszynowym. Otrzymane wyniki potwierdziły prawidłowość rozważań teoretycznych.
