A Research Review of Protection for DC microgrid
摘要
Abstract
With the promotion of new energy resources and popularization of DC loads, DC microgrid which is more efficient for distributed generation to access receives more and more attentions, and relay protection is one of the key technologies for the development of DC microgrid. This paper aimed to systematically introduce the research situation about the protection technology for DC microgrid system at home and abroad. The development status of a variety of protection devices used in DC system was presented, and research results for DC grounding type were summarized. Considering that the DC-Link capacitor discharges instantly and power electronic devices were vulnerable to the high fault current, various schemes about quickly cutting off or limiting the fault current were compared. On this basis, various protection schemes were discussed and analyzed. Finally, this study identified the future trends and provided solutions to key issues in the field of protections of DC microgrid.关键词
