1. A system for damping power system oscillations comprising:
a damping device controller to generate a damping control signal to compensate for a plurality of oscillation modes in the power system oscillations, the damping device controller comprising:
a plurality of outer closed loop paths each including an adaptive controller configured to determine an individual oscillation mode from at least one power system measurement signal, and to generate an adaptive control signal to shift at least one open loop pole of an inner loop path related to the individual oscillation mode to a closed loop location;a delay block associated with an output of the adaptive controller, the delay block configured to delay the generated adaptive control signal of the associative adaptive controller by a time sample with respect to a generated adaptive control signal of a previous adaptive controller;summation means configured to generate a damping control signal by summation of the delayed adaptive control signals of each of the plurality of outer closed loop paths; and a damping device to generate a damping signal based on the damping control signal. |
