Abstract :
Korean navy is now investigating how new naval destroyer can be designed by Integrated Full Electric Propulsion (IFEP) system. The operating cost of the electric propulsion system is smaller than that of the mechanical propulsion system. However, the existing IFEP system is still spending an enormous fuel due to Navy´s conservative operating concept-Dual Generator Operation-for higher reliability. To improve the fuel-efficiency of the IFEP power system, the Single Generator Operation (SGO) is a rational solution because it could maximize the load factor of the generator. But the SGO is difficult to be accepted by the Navy as a reliable operating concept without full back-up of the entire electric power including propulsion power. This paper proposes a novel IFEP system having Battery Energy Storage System (BESS) which can guarantee reliable SGO. The feasibility, effectiveness and some design requirements of the proposed Integrated Power System (IPS) is discussed by computer simulations and reference data.
