Abstract
A method for recognizing an electrical oscillation in an electrical power supply system, in which an electrical oscillation variable is determined for at least one measuring point in the power supply system. Parameters of an electrical oscillation are calculated on the basis of a time curve of the oscillation variable for the at least one measuring point, and the presence and type of an electrical oscillation is deduced using the parameters. To be able to provide correct parameters for assessing the oscillation in a timely fashion after the start of the oscillation, it is proposed that the number of those successive values of the oscillation variable from which the parameters of the electrical oscillation are calculated is adapted dynamically to the sequence of values of the oscillation variable.
