Abstract :
DC power system is gaining popularity. Research is being conducted worldwide on implementation of LVDC (low voltage direct current) and MVDC (medium voltage direct current) in applications such as ship power systems. One major hurdle to this path is the immaturity of the protection systems. This paper deals with the modeling of LV/MVDC power system with different marine loads and faults. Since LV/MVDC power systems are still in preliminary stages, their modeling and fault analysis will help in addressing the requirements of various protection strategies. The system modeling and fault simulations are done in simulation software Power Systems Computer Aided Design (PSCAD). The components of DC ship power system are also described.
