Journal ArticleDOI
High speed differential protection for smart DC distribution systems
TL;DR: Results show the implementation approach can consistently achieve protection system operating within the order of a few microseconds and validate the overall protection operating times in a low voltage environment.
Journal ArticleDOI
Optimizing the Roles of Unit and Non-unit Protection Methods Within DC Microgrids
TL;DR: A detailed analysis of dc microgrid behavior under fault conditions is presented, illustrating the challenging protection requirements and demonstrating the shortcomings of non-unit approaches for these applications, and the authors show how these may be met using COTS technologies.
Journal ArticleDOI
Validation of Fast and Selective Protection Scheme for an LVDC Distribution Network
TL;DR: In this paper, the authors present experimental results of a prototype advanced protection scheme designed to help enable low-voltage direct-current (LVDC) distribution networks for utility applications, which uses multiple intelligent electronic devices relays in combination with controllable solid-state circuit breakers to detect and locate DC faults.
Journal ArticleDOI
Determination of protection system requirements for dc unmanned aerial vehicle electrical power networks for enhanced capability and survivability
TL;DR: This study seeks to determine the operating requirements of protection systems for compact DC networks proposed for future UAV applications, with particular emphasis on dealing with the issues of capacitive discharge in these compact networks.
Proceedings ArticleDOI
Optimizing the roles of unit and non-unit protection methods within DC microgrids
TL;DR: In this paper, the authors present a detailed analysis of dc microgrid behavior under fault conditions, illustrating the challenging protection requirements and demonstrating the shortcomings of non-unit approaches for these applications.
