“…Protection against the electric faults is of paramount importance on vessels, as the loss of any system on board could result in dangerous conditions for the vessel or for personnel safety [3]. The damage produced by a short‐circuit is proportional with the fault current [11] and on vessels phase–phase (PP) and three‐phase (3P) faults produce the most intense fault currents. Overcurrent (OC) protection is widely used for detection of these abnormal conditions on vessels [1], but its correct operation can be compromised in some cases.…”

“…However, the time needed by the primary protection to clear such faults can be relatively long in some cases. The damage produced to the electrical equipment is proportional with the fault current and the fault duration, so a decrease of the trip time can reduce the equipment damage and the danger to which the personnel is exposed [8].…”

-more and more maritime applications as marine vessels and offshore platforms need an adaptive protection power system. However, the adaptive protection is yet to be implemented in the maritime sector. Usually, the adaptive protection implies the existence of a central control unit that monitors the entire electrical network and changes the relay settings accordingly, but this approach is not adequate for the maritime power systems. This paper propose a decentralized adaptive protection method, where each protection relay is able to identify by itself the network status without the need of a central control unit. The new adaptive protection method is based on communication between the overcurrent relays and the equipment that could affect the protection system, such as circuit breakers and generators. Using PSCAD, the proposed method is implemented in a test medium voltage maritime power system that possess some of the characteristics of the maritime applications, as variable generation and network reconfiguration.Index Terms -adaptive protection, inter-tripping, maritime applications, overcurrent characteristic, protective relays.
