Damping control design based on time-domain identified models

This paper presents an integrated approach for designing damping controller s for large power systems. First. a low-order model is identified from a ti me simulation of the nonlinear power system model. Then an exact multi-moda l decomposition is used to develop design indices for selecting an appropri ate input signal to the controller, The method is illustrated with the desi gn of thyristor-controlled series compensator damping controllers in two te st systems.
