Title:
METHOD AND DATA PROCESSING ARRANGEMENT FOR DETERMINING THE FREQUENCY, AMPLITUDE AND ATTENUATION OF AT LEAST ONE OUTPUT OSCILLATION IN AN ELECTRICAL ENERGY SUPPLY NETWORK
Document Type and Number:
WIPO Patent Application WO/2014/056531
Kind Code:
A3
Abstract:
A method for determining frequency, amplitude and attenuation of at least one output oscillation (7) in an electrical energy supply network, according to which method a time window (4, 5, 6) of predefined duration is used, and momentary values for the output determined within the time window (4, 5, 6) are used to determine frequency, amplitude and attenuation of the at least one output oscillation (7), characterized in that at least one further time window (6) is used, wherein all the time windows (4, 5, 6) are each of different duration, and that time window, within the duration of which a predefined number of oscillation processes of the output oscillation concerned falls, is used for determining frequency, amplitude and attenuation. The invention also relates to a data processing arrangement.
