要約(日本語): The paper proposes the use of type-58 S.M. model and CAO LOAD FLOW for ATP. The type-58 S.M. model is based on phase-domain instead of conventional dq0-domain to improve numerical stability. Futhermore, in the type-58 S.M. model, the saturation simulation has been modified in both the computation of flux linkages and the representation of saturation curve. The load flow computation of FIX SOURCE assumes that the terminal voltages of S.M. are balanced even though connected transmission lines are not balanced. Therefore, this means that the steady state simulation is inconsistent with the transients simulation. However, the load flow computation of CAO LOAD FLOW allows the terminal voltages of type-58 S.M. may be unbalanced when power system is unbalanced, and can obtain much better convergence. Finally, by means of several tests, the advantages of type-58 S.M. model and CAO LOAD FLOW are shown.
