Abstract：Specific forms and characteristics of four MV and LV RR power supply architectures are analyzed theoretically. The technical characteristics of MV RR architecture and 2N architecture of distributed diesel generator are compared and analyzed in terms of construction cost，reliability and power supply efficiency. In this paper，the corresponding operation and maintenance guarantee measures are put forward and an RR architecture that can realize the electrical isolation of two power sources are introduced for the electrical isolation problems existing in the MV RR architecture of distributed diesel generators.

Key words：RR architecture；2N architecture；data center；architecture analysis； operation and maintenance support；construction cost；reliability；power supply efficiency
