Abstract :
This paper deals with modeling and characteristic analysis of a large powered electric ship propulsion system. Particularly, electric power system modeling has been accomplished in accordance with the electric power network mainly composed of generators, switchboards, variable frequency devices, electric motors, and etc. In addition, electric power system analysis has been performed via load flow analysis. In particular, abnormal operating condition of the short circuited network is thoroughly investigated for estimating the short circuited current with the short time rating and implementing the system safety with the protection relay(IEEE Std. 141-1993).
