| Summary: | DC shipboard power systems are gaining popularity primarily because they allow each prime mover to be operated at an optimal speed with respect to fuel efficiency. Another notable advantage is the simplified operation of generators in parallel without concern for frequency synchronization. Careful design of the protection system for dc shipboard power systems is necessary as the continuity of electrical power is required to carry out critical marine missions. In this paper the protection requirements for MVDC shipboard power system with multiple parallel generation system are discussed and the `Directional Protection' method is presented as an attractive candidate. The backup protection algorithm is also developed for increased redundancy. The protection settings for main and backup protection system are discussed and the results are presented. The various challenges associated with the directional protection are also highlighted. |
