Abstract：A detail review is made on the advantages,research status,research contents,research results and application prospects of user‑side DC power distribution technology. The author thinks that the research of DC distribution system focuses on three aspects:distribution system,distribution equipment and electrical equipment,and that the DC distribution system is entering the pilot promotion stage from the research stage,but there are still some application difficulties to be solved before the full popularization of the system. This paper also presents the application focuses at present and prospects the application in the future.
