Tidal energy has the advantages of high energy density, stable energy and easy prediction. The rated power of the unit is gradually expanded, and it has good commercialization prospects.

[0003] In the existing tidal power engineering design, the tidal power generator set and the booster station are arranged in different areas. The power generated by the tidal power generator set is boosted by the booster device, transmitted to the booster station through the submarine cable, boosted again, and then transmitted to the land through the submarine cable and connected to the power grid. The length of the submarine cable is long, and the power loss is large. For the arrangement of the tidal power generator set and the booster station in different areas, a platform needs to be separately made on the basis of the tidal power generator set to arrange the unit lifting device. When maintenance is needed, the unit is lifted out of the water surface for maintenance. At the same time, the foundation of the booster station needs to be separately made to maintain the safe and stable operation of the booster station structure, which greatly increases the construction cost and construction time. In order to reduce power loss, save cost and shorten construction time, it is particularly important to optimize the arrangement design of the booster station and the tidal power generator set.
