TY  - PAT
AB  - The invention provides a method, device and computer program product for providing improved control of power or voltage oscillation damping in a power transmission system. The device comprises a magnitude obtaining element (30) configured to obtain an instantaneous magnitude of a signal ( I ΔP I ) representing a deviating oscillation in at least one element (12) of the power transmission system, a slope investigating element (58) configured to determine the rate of change of the signal, and a first processing block (34) comprising an integrating element (38) configured to integrate the instantaneous magnitudes with an integrating factor (Ki) that is based on the determined rate of change. The first processing block is further configured to form a phase compensation angle (c) based on the integrated instantaneous magnitude for use in a damping control signal generating unit in order to provide power or voltage oscillation damping of the system.
