500kV offshore booster station

Abstract

The invention relates to the technical field of offshore wind power generation, and discloses a 500kV offshore booster station which comprises a first-layer deck, a second-layer deck, a third-layer deck and a top-layer deck which are sequentially arranged from bottom to top. The first-layer deck is provided with a submarine cable bridge used for leading submarine cables to the second-layer deck. The second-layer deck is provided with a high-voltage power distribution room, a medium-voltage power distribution room, a main transformer room, a reactor room, an electrical secondary equipment room and a heat dissipation equipment room, the third-layer deck is provided with a low-voltage power distribution room, and the low-voltage power distribution room is arranged above the electrical secondary equipment room. The high-voltage power distribution room, the medium-voltage power distribution room, the main transformer room and the reactor room penetrate through the three-layer deck and extend to the lower surface of the top-layer deck. According to the invention, the arrangement is reasonable and compact, and the 500kV output voltage grade can be met, so that the output voltage grade is improved, and the transmission capacity of the single-circuit submarine cable is increased.

Description

technical field [0001] The invention relates to the technical field of offshore wind power generation, in particular to a 500kV offshore booster station. Background technique [0002] As a renewable energy, wind energy has many advantages such as large reserves, greenness, safety, flexibility, low power generation cost, simple operation and maintenance, and various power generation methods, and has attracted more and more attention. In recent years, due to the high density and relatively stable offshore wind energy resources, offshore wind power has gradually become a research hotspot and entered the stage of large-scale development. Compared with onshore wind power, offshore wind power has the following advantages: offshore wind speed is higher than that on land, wind resources are abundant, sea surface roughness is small, wind energy quality is high, wind shear is small, and high towers are not required; The turbulence intensity is small, and generally has a stable domina...
