Offshore wind plant arrangement structure and arrangement method

Abstract

The invention relates to an offshore wind power plant arrangement structure and an arrangement method. The offshore wind power plant arrangement structure comprises an offshore wind power plant whichis divided into a plurality of block wind power plants by offshore separation areas, and the offshore wind power plant arrangement structure is characterized in that an offshore booster station is arranged in each block wind power plant; a power generation quantity output end of each block wind power plant is connected with an electric quantity input end of the offshore booster station in the block wind power plant to form a power generation quantity boosting structure of each block wind power plant; the electric quantity output ends of all the offshore booster stations are connected togetherthrough submarine cables, and the offshore booster station in one block wind power plant close to the land is provided with a land transmission electric quantity output end to form a land transmissionelectric quantity output end of the offshore wind power plant 1. And the land transmission electric quantity output end is connected with the electric quantity input end of a land centralized controlcenter through a group of landing cables to form a simplified structure type offshore wind power plant arrangement structure. The offshore wind power plant arrangement structure has the characteristics and improvements of few electrical loops, small sea area, low project cost, environmental pollution reduction and the like.

Description

technical field [0001] The invention relates to an arrangement structure and an arrangement method of an offshore wind farm. It belongs to the technical field of distributed power supply method. Background technique [0002] Offshore wind farms are generally arranged in a complete sea area, but when they are divided into two or more areas by anchorages or other marine protected areas (hereinafter referred to as separation areas), it is necessary to choose the overall layout that is both in line with the plan and the most economical. Program. [0003] In the prior art, when the complete offshore wind farm is divided into two independent offshore wind farms in the east and west by the middle separation area, the respective landing methods are usually adopted: one is to pull a group of offshore cables from the wind farm in the east (each group Offshore cables (including two offshore cables) bypass the anchorage from the seabed to the vicinity of the wind farm in the west area...

AI Technical Summary

Problems solved by technology

[0004] One of the purposes of the present invention is to provide an offshore wind farm layout structure with electrical Outstanding substantive features and significant progress such as fewer submarine cable loops, small sea area, low project cost, and reduced environmental pollution

[0005] The second object of the present invention is to provide a layout method for offshore wind farms, which has the advantages of less electrical circuits, Outstanding substantive features and significant progress such as small sea area, low project cost, and reduced environmental pollution
