POWER OSCILLATION DAMPING CONTROLLER

摘要

There is provided a power oscillation damping (POD) controller (120) for a power generation device such as a wind turbine device. The POD controller (120) receives an oscillation indicating signal (128) indicative of a power oscillation in an electricity network and provides an oscillation damping control signal (134, 135) in response to the oscillation indicating signal (128), by processing the oscillation damping control signal (128) in a signal processing chain (136, 138). The signal processing (136, 138) chain comprises a filter (140) configured for passing only signals within a predetermined frequency range.
