Characteristics of Operation of 400 Hz Frequency (Osobennosti Raboty Elecktroenergeticheskikh Sistem Chastotoy 400 Gts),

Today it is apparent that the use of 400 Hz frequency electric energy systems EES on small-tonnage fast vessels produces effective results. A number of river boats, as well as one of the first sea-going vessels -- the controllable hydrofoil passenger motorship TAYFUN -- are being successfully operated with this type of electric energy systems. This as yet little experience permits making a deduction that the expectations of improvement of the overall weight indices, as well as simplification and improvement of other characteristics of the systems resulting from higher current frequency have been justified. However, some specialists in marine electrical technology raised the question of complications in certain operating phases of the 400 Hz frequency electric energy systems as compared to the conventional systems. It was only natural, therefore, that designers of fast small-tonnage ships rightly demanded that all of these problems be resolved. It has now become possible to generalize certain phases of work that have been completed and to answer the above questions.
