Modulationsalgorithmen zur Dämpfung von Leistungspendelungen mittels Wirk- und Blindleistungssteuerung

Abstract

Die Verbesserung des Dämpfungsverhaltens von Energieversorgungssystemen kann durch die gemeinsame Steuerung der Wirk- und der Blindleistung erreicht werden. Hierzu wird als Stellglied ein Wirkleistungsspeicher benötigt, der über Stromrichterschaltungen an das Netz gekoppelt ist. Zur Ansteuerung wird eine optimale Steuerstrategie entwickelt, welche die Zustandsvariablen des Systems nutzt. Da letztere meßtechnisch nicht alle erfaßbar sind, müssen lokale elektrische Signale gefunden werden, mit denen eine möglichst gute Pendeldämpfung durchführbar ist. Diese sind in ihrer Wirkung zu vergleichen. The damping of power system oscillations could be improved by coordinated active and reactive power control. For this purpose an active power storage is connected to the network. The direction and the magnitude of the power flow is controlled through converters. An optimal control strategy is presented, which uses the state vaiables of the system. These quantities are not available at the SMES bus. For that reason it is necessary to find electrical signals, that could be used for a good damping of power oscillations. In this paper locally measurable quantities and their applicability for SMES control are discussed.
