Abstract

This paper gives an overview on issues and challenges of DC shipboard distribution protection. Typical fault characteristics in DC shipboard distribution systems are determined by different sources at DC faults. Issues in protection design include fast and accurate fault current estimation, fast and selective fault location methods, and effective fault current control. One main challenge in practical applications of DC protection is cost effectiveness, which impacts applications of DC distribution technology.
