Abstract : This proiect aimed at the development of new protection and configuration management schemes for the next generation DC zonal shipboard electrical systems (DC SES). The research has demonstrated the feasibility of two new options for the protections devices. First approach uses the Voltage Source Converters, and the second approach uses the new solid-state based protection devices (SSPD) for limiting and interrupting the fault currents. Then, a new agent based protection scheme using these new devices has been developed for effective protection of DC SES. It has been shown that these protection agents, which are associated with protection devices, can detect and isolate the faults very fast - less than 3-4 ms. Second part of the research has focused on the main design issues related to configuration management on DC SES after a fault, and a new scheme has been developed. The method uses the protection agents to localize the fault fast and thus assure continuity of supply to the critical loads even under battle damage conditions.
