The invention provides a DP3 ultra-deep water well drilling equipment power distribution system. A power system is a 11KV medium-voltage system. The power system of a whole boat consists of three groups or four groups of medium-voltage power generators, wherein each group also comprises two 7370KW medium-voltage generators, the power generators are respectively arranged in three or four A60 divided machine cabins, three main power systems need to be in an A60 division state, and need to be in the complete mutual A60 division state from the corresponding medium-voltage power distribution systems to a transformer to a 440V low-voltage power distribution plate. Through the optimization on the whole boat power system and the reinforcement on the region power supply principle, the power distribution system scheme is regulated, and the DP3 main cable path is optimized. Through optimizing the arrangement of the well drilling power distribution system and carrying out power supply load and balance calculation on re-optimized scheme, the whole power distribution system is more reasonable, the construction difficulty is reduced, the cable and labor cost can be reduced, and the power distribution system has the advantages that the the operability is high, the application range is wide, and the difficult problems of design and layout of the boat body power distribution system are solved.
