Structure in the Computation of Power-System Nonlinear Dynamical Response

Methods are presented for simulating multimachine power-system dynamical response on the basis of Park´s equations including the effects of an arbitrary number of circuits on the rotors of the synchronous machines. These methods allow a direct calculation treatment of effects that are neglected or treated only approximately in many power-system simulation programs, namely, amortisseur damping torques and subtransient saliency.
