        Abstract: Introduction was made to the design characteristic of the electrical system and medium voltage buses transfer of AP1000 nuclear power plant. This paper compared the difference of medium voltage buses transfer between nuclear power plant and normal thermal power plant and analyzed the medium voltage buses transfer characteristic and design optimization procedure of AP1000 nuclear power under abnormal operation mode. Via design optimization, the buses transfer wasn’t be blocked any longer when auxiliary boilers were in operation. This paper gave the relevant suggestion, which provides references for the follow-up AP1000 project.
        Key words: nuclear power plant; medium voltage buses transfer; switch design
