Embodiment 1

[0033] Such as figure 1 As shown, a wind power foundation protection system provided in this embodiment includes a monopile foundation 1 and an impressed current protection device 2 arranged on the monopile foundation 1 .

[0034] In this embodiment, the method of applying current is used to realize the cathodic protection of the single pile foundation. Compared with the protection method using sacrificial anodes in the prior art, the structure of the protection device corresponding to the method of applying current is simple and easy to assemble , at the same time, the external current can take into account the protection of steel piles in the sea mud area, and can even play a better protective effect on the seabed clay layer with higher resistivity, so as to realize the comprehensive protection of steel piles.

[0035] Such as figure 1 As shown, a bracket 3 is detachably installed on the outer peripheral surface of the monopile foundation 1 in this embodiment, and the appli...

Embodiment 2

[0044] This embodiment provides a wind turbine, including the wind power foundation protection system in Embodiment 1 above, and has all its technical advantages, which will not be repeated here.

Embodiment 3

[0046] This embodiment provides an offshore wind farm, including an offshore booster station and several wind turbines in the above-mentioned embodiment 2 electrically connected to the offshore booster station.

Abstract

The invention relates to the technical field of offshore wind power, in particular to a wind power foundation protection system, an offshore wind power generator set and an offshore wind power plant.The wind power foundation protection system comprises a single-pile foundation and an impressed current protection device arranged on the single-pile foundation. In the wind power foundation protection system, cathodic protection to the single-pile foundation is realized by adopting an impressed current method, compared with a sacrificial anode protection method in the prior art, the protection device corresponding to the impressed current mode is simple in structure and convenient to assemble, meanwhile, protection of a steel pile in a sea mud area can be considered by the impressed current,even a seabed clay layer with the higher resistivity can also be well protected, and thus the steel pile is comprehensively protected.

Description

technical field [0001] The invention relates to the technical field of offshore wind power, in particular to a wind power foundation protection system, an offshore wind power unit, and an offshore wind farm. Background technique [0002] my country has very rich offshore wind resources. At the same time, the eastern coastal areas of our country are economically developed and energy is in short supply. Therefore, the development of offshore wind power has become an important part of my country's strategic energy. [0003] The basic equipment of offshore wind power is susceptible to corrosion caused by salt spray, ocean atmosphere, spray splash, etc. In the prior art, cathodic protection is generally adopted in order to protect offshore wind power steel structures and the like. The existing offshore wind power monopile foundation mostly adopts the cathodic protection method of sacrificial anodes. The installation of sacrificial anodes is mainly in the form of anode groups sur...
