Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] Such as Figure 1-3 As shown, a double-deck offshore booster station of the present invention includes upper blocks, jacket structures (30, 31) and pile foundation structures, and horizontal bracing, diagonal The struts are connected to each other to form a space truss, which strengthens the lateral stiffness of the jacket, and nests the pile foundation structure at the bottom of the offshore booster station (not shown in the figure); the upper block is fixed on the pile foundation structure through the jacket structure (30, 31) above.

[0029] The upper block adopts a frame-support system, and the main body is a two-story mixed steel structure building. The main body is divided into two floors by the first deck 35, the second deck 34 and the top deck 33, which are the first equipment floor and the second equipment floor; Each steel st...

Abstract

The invention relates to a double-deck offshore booster station which comprises an upper module, a jacket structure and a pile foundation structure, the upper module is divided into two layers of mixed steel structure buildings by a first deck, a second deck and a top deck, and the two layers of mixed steel structure buildings are respectively a first equipment layer and a second equipment layer. A traditional bottom cable layer is optimized into a 35kV cable interlayer chamber, a traditional design cable layer is canceled, a main transformer accident oil collecting device is arranged in an original cable layer and welded to the bottom of an offshore booster station platform, and a three-deck structure of an original offshore booster station is optimized into two decks. A 35kV switch cabinet and a main transformer are connected in a copper pipe bus upper wire inlet mode, the main transformer and the GIS equipment are connected in a high-voltage oil and gas sleeve upper wire inlet mode, the space utilization rate of the offshore booster station is further improved, and compared with traditional offshore booster station arrangement of the same installation scale, the total area can be reduced to 1461 square meters and is reduced by about 36%; and the total height can be reduced to 13.5 m and is reduced by about 30.7%.

Description

technical field [0001] The invention relates to the field of new energy and power systems, in particular to a double-layer offshore booster station. Background technique [0002] Compared with onshore wind power, offshore wind power has many advantages such as abundant wind resources, no land occupation, high utilization hours of power generation, and suitable for large-scale development. However, due to the complex marine environment, the price of offshore wind power host equipment is higher, the foundation weight of wind turbines such as single piles and jackets is heavy, and the manufacturing cost is high. Offshore construction also needs to be equipped with professional equipment such as large construction ships and piling hammers. With the development of the sea, the length of buried submarine cables continues to increase, which leads to the fact that the construction cost of offshore wind power is much higher than that of onshore wind power, which is about 2 to 3 times...
