摘要：
In this paper, an analysis results for the protection of a DC micro-grid is described. The 400V DC micro-grid consists of a wind power system (Permanent Magnet Synchronous Generator, PMSG), a photo-voltaic system, a fuel cell system and energy storages. Abnormal operating conditions during various faults are studied. According to a series of studies, a protection scheme for a DC micro-grid is suggested. An algorithm which can be used for discriminating the stable abnormal operating condition from the faults which should be cleared is also presented. All case studies are simulated with PSCAD /EMTDC.
