Pure electric official business boat power system

The invention belongs to the technical field of pure electric power of boats, and relates to a pure electric official business boat power system, which comprises at least two groups of main circuit topological structures with the same structure. The structure comprises a power module, and power is supplied to a direct current busbar through a bidirectional DC-DC voltage stabilizing module and a fuse; the direct-current busbar is used for accessing and distributing electric energy of the whole boat, and the direct current busbar is provided with at least one fuse; direct current of the power module is connected through the bidirectional DC-DC voltage stabilizing module and the fuse and is inverted into alternating current through the fuse and the DC-AC inversion module to be supplied to anelectric propulsion system and a whole boat auxiliary and daily load for use. The bidirectional DC-DC voltage stabilizing module, the DC-AC inversion module and the DC busbar are respectively communicated with the power manag
