Model-based method for designing an oscillation damping device and installation having such an oscillation damping device

摘要

A model-based method for designing an oscillation damping device and an installation having such an oscillation damping device are provided. Oscillation damping devices for turbogenerators in gas and/or steam power plants serve the purpose of reducing power oscillations which occur. Such a device can be designed on the basis of a model. A physical linear model is used and a differentiating effect is taken into account when designing for improving a damping response, thus ensuring that an output signal of the oscillation damping device is zero in a steady state.
