    Abstract: This passage discussed the common connection mode of low-voltage alternating current and direct current system in various voltage grades and below 220 kV, carried out summary for several special connection modes and analyzed their characteristics and the matters needing attention in the process of routine operation and maintenance. This paper expected the development trend of alternating current and direct current integration power supply in intelligent substation, which provides references for operation and maintenance of low-voltage alternating current and direct current system in substation.
    Key words: station-service power; connection mode; operation and maintenance
