Abstract: Protection technology is an important foundation to ensure safe and reliable operation for direct current micro-grids. Based on direct current (DC) micro-grids features, analysis was made to cautions in protection system design. This paper described DC micro-grids common fault types,summarized study present status and key technology of protection system for DC micro-grids, and raised subsequent study suggestion for DC micro-grids protection technology.
         Key words: direct current micro-grid; protection system; fault detection; direct current circuit breaker
