要約(英語): Electromagnetic transient (EMT) simulations of relatively-large power systems have become quite common, for instance, in the case where simulations of HVDC converters are carried out with large AC power systems connected to the converters. Thus, the increase of computation time is a serious concern. To reduce computation time, this paper proposes a method to reduce computational demand of a remote power system which is located far from the source of a transient event to be simulated. In the proposed method, the remote power system which is supposed to be represented by a three-phase EMT-based model is reduced to a single-phase phasor-based model, and the size of the circuit to be simulated is thus reduced and the dynamics calculations of inductors and capacitors included in the remote power system are neglected. The calculation algorithm of generator models included in the remote power system is also simplified. The proposed method has been applied to EMT simulations of the WEST 10 benchmark power system prepared by the IEEJ, and it has been shown that the computation time is remarkably reduced without significant loss of accuracy if the portion assumed to be the remote power system is sufficiently far from the source of a transient event.
