Abstract

The synchronous generators with compound system excitation are used widely in the ship’s electrical power systems. In the paper the compound system excitation model is suggested, which takes into account the compound transformer processes. This allows taking into account all his property, which has great importance to account the transformer forcing features on a transient processes. A transient processes, caused by various disturbances, are investigated by modeling. Received results show the accuracy and usefulness of suggested model.

Keywords

Compound system excitation of ship’s synchronous generators, automatic voltage regulator, ship’s electrical power system models.
