An offshore platform for an AC booster station in an offshore wind farm

Abstract

The invention relates to an offshore platform used for an alternating-current booster station of an offshore wind plant. The offshore platform is characterized by comprising a combined steelwork building with a bottom floor, a first floor, a second floor and a top floor, each floor of the steelwork building is composed of several function rooms, and the bottom of each floor of the steelwork building comprises a deck composed of a plurality of steel plates. The offshore platform comprises a bottom floor deck, a first floor deck, a second floor deck and a top floor deck. The first floor deck is divided into a front end part and a rear end part by the steel plates, the front end part is divided into five electrical rooms through the steel plates, the middle electrical room is a 35kV power distribution device room, and the rest are two primary transformer rooms and two primary transformer radiator rooms, which are arranged in symmetry to the 35kV power distribution device room. The rear end part is divided into five electrical rooms including a 220kV power distribution device room, a grounding transformer room, an SVG control room, an SVG equipment room and an outdoor and indoor heat radiation equipment area from left to right. The area of the offshore platform is saved, line outgoing is facilitated, investment is saved, and the offshore platform can be widely applied to the platform design of the alternating-current booster station of the offshore wind plant.

Description

technical field [0001] The invention relates to the field of new energy and power systems, in particular to an offshore platform used for an AC booster station of an offshore wind farm. Background technique [0002] The world's offshore wind power has developed rapidly and has entered the stage of large-scale development. my country's offshore wind power construction has also kicked off. However, due to the lack of experience in the design and construction of offshore wind power, the technical system for offshore wind power construction has not yet been developed and perfected. According to the offshore wind power planning of coastal provinces and cities, offshore wind power will be vigorously developed in the next 30 years. At present, the planned capacity of a single offshore wind farm is mostly more than 200MW-300MW, and the distance from the coast is more than 15 kilometers. Referring to the international experience, such wind farms generally need to build offshore boos...

AI Technical Summary

Problems solved by technology

Offshore booster platforms are expensive and difficult to construct, and the offshore environment is complex, heavy salt fog, humid, equipment layout conditions are limited, operation and maintenance are inconvenient, and construction costs are high

At present, there are no construction examples of offshore booster stations in China, so it is necessary to study the platform design of offshore booster stations
