| 摘要 |
The invention is related to a method, resonance handling device and computer program product for handling resonances in a power transmission system. The resonance handling device (28) comprises a resonance frequency determining unit (22) configured to obtain measurements (y1, y2, yr) from measurement devices(12, 14, 16) in the power transmission system, apply the measurements in at least one state space model (M1, M2) and determine modal resonance frequencies(omegaj)in the system based on the application of the system measurements in said state space model, and an activity determining unit(24) configured to determine the modal activity of at least one of the resonance frequencies. |
