[0003] At present, the integrated development of the two at home and abroad has taken shape. The Netherlands has established the world's first offshore wind power hydrogen production project - PosHYdon, using the Q13a-A platform as a test platform to verify the feasibility of offshore wind power hydrogen production. After hydrogen is produced, it is mixed with natural gas and integrated into the national pipeline network through existing natural gas pipelines.

DETAILED DESCRIPTION

[0036] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0037] like Figure 1-9 As shown, a lightweight offshore booster station and an offshore hydrogen production and hydrogenation fusion platform, the fusion platform 3 is arranged at the edge of the offshore wind farm, near the waterway 21, to provide hydrogen for passing ships and transport hydrogen for transport ships. The electric energy generated by the wind turbine 1 of the offshore wind farm is transmitted to the fusion platform 3 through the on-site power collection line 2, and part of the electric energy is transmitted to the hydrogen production functional area through the battery room a46, and the electric energy is converted into hydrogen energy for storage and transportation through the water electrolysis hydrogen production system; the other part of the electric energy is boosted in the substation functional area, and finally the boosted electric energy in the substation functional area is sent to the onshore centralized control center 5 through the submarine cable 4.

[0038] In this embodiment, the first and second floors of the fusion platform 3 are hydrogen production functional areas, and the third to fifth floors of the fusion platform 3 are power transformation functional areas; and the first to fourth floors of the fusion platform 3 use indoor inclined ladders, and the fifth floor uses outdoor inclined ladders. The roof deck layer of the fusion platform 3 is connected to the fourth floor of the fusion platform 3 by outdoor stairs, and each floor is provided with a staircase lap platform to ensure the functional requirements of escape and rescue and equipment maintenance in the power transformation functional area; thereby, the lightweight design of the power transformation functional area is ensured while meeting the functional requirements, and the construction cost of the entire station is reduced to the maximum extent. At the same time, an escape passage 11 covering the entire area is set between the main plant and the auxiliary plant on each floor of the fusion platform 3.

[0039] like Figure 2 As shown, one layer of the fusion platform 3 serves as the lower layer of the hydrogen production functional area, and a water replenishment and alkali preparation room a11 and a hydrogen production purification room a12 are arranged in the middle area of ​​the first layer, wherein the alkali preparation equipment 6 equipped in the water replenishment and alkali preparation room a11 includes a chiller, a water replenishment pump, an alkali tank, a water tank, and an alkali preparation pump, which are used to prepare 20%-30% NaOH or KOH as an electrolyte to provide ion conductivity, and a hydrogen production purification equipment 7 is arranged in the hydrogen production purification room a12, and the hydrogen production purification equipment 7 includes a rectifier cabinet, an electrolytic cell, and ancillary equipment frames required for hydrogen production, which are neatly arranged to generate hydrogen and oxygen by electrolyzing water.

[0040] Cable shafts b6 are set up on the north and south sides of the main plant for the up and down crossing and connection of power cables 8, hydrogen pipelines 9, and cooling water pipes 10. The cooling water pipes 10 connect the hydrogen production equipment rooms on the first and second floors. The low-temperature seawater extracted from the offshore lifting and desalination equipment room b3 is circulated and cooled through the cooling water pipes 10, through the water replenishment and alkali preparation room a11, hydrogen production and purification room a12, hydrogen buffer zone a21, hydrogen compression area a22 and other equipment rooms to the pump room b2, forming a closed cooling water system to ensure the safe operating temperature environment of equipment such as electrolyzers.

[0041] The east and west sides of the first floor of Fusion Platform 3 are the auxiliary plant areas. The west area is arranged from north to south with the offshore lifting and desalination equipment room b3, the pump room b2, and the first floor staircase b11 in the west area. The indoor stairs of Fusion Platform 3 are combined with the staircases on each floor to facilitate maintenance personnel and equipment to go up and down. The offshore lifting and desalination equipment room b3 is used for the extraction of low-temperature seawater for the cooling water system on the one hand, and for seawater desalination on the other hand to provide raw materials for water electrolysis and hydrogen production. The main function of the pump room b2 is to store the lifted and desalinated seawater. Part of it is used for circulating cooling of the cooling water system, and the other part is stored in the water tank for fine water mist fire water for the entire station.

[0042] The east area of ​​the first floor of fusion platform 3 is arranged from north to south with the first floor stairwell b11, control room b5 and hydrogenation equipment room b4. The control room b5 serves as the voltage monitoring and voltage stabilization function for the hydrogen production functional area, and the hydrogenation equipment room b4 is used to transport hydrogen to passing ships.

[0043] like Figure 3As shown, the second floor of the fusion platform 3 is the upper floor of the hydrogen production functional area. The second floor of the hydrogen production functional area is basically arranged in the same way as the lower floor of the hydrogen production functional area. In the main plant in the middle area of ​​the second floor, a hydrogen buffer a21 and a hydrogen compression area a22 are set. The hydrogen buffer a21 is neatly arranged with slow hydrogen tanks 12 to collect and cache the hydrogen obtained from the hydrogen production purification room a12, which can reduce the pressure fluctuation of the output hydrogen and stabilize the flow rate; the hydrogen compression area a22 is equipped with a hydrogen compressor 13 for compressing hydrogen. The west side auxiliary plant on the second floor of the fusion platform 3 is from north to south, including the space above the seawater lifting and desalination equipment room b31, the fresh air machine room b7 and the second floor staircase b21 in the west area; the east side auxiliary plant on the second floor of the fusion platform 3 is from north to south, including the second floor staircase b21 in the east area, the HVAC room b8 and the space above the hydrogenation equipment room b401.

[0044] like Figure 4 As shown, the third to fifth floors of the fusion platform 3 are the substation functional area, and the boost substation module is set up on this basis. The difference from the existing boost substation is that the main transformer radiator of the boost substation module in this embodiment is arranged in a staggered manner with the main transformer body, and the GIS floor height layout is optimized to arrange it below the roof layer, which greatly compresses the plane space and the overall floor height and reduces the weight of the entire station. The third floor of the fusion platform 3 is used as the bottom floor of the substation functional area. In the middle area, the main plant is equipped with a switch cabinet room a31, a main transformer room a32, a low-voltage distribution room a33, an emergency distribution room a34, a grounding transformer and station power room a35, a small resistance cabinet room a36 and a secondary equipment room a37; its room functions are the same as the existing offshore substation platform functional rooms. Hydrogen storage area b9 and three-story stairwell b31 are arranged on both sides of the auxiliary plant. Among them, the hydrogen storage area b9 is equipped with a detachable hydrogen tank 14 to store compressed hydrogen, which is placed in the open air for easy external transportation. Cable shafts b6 identical to those in the hydrogen production functional area are also provided on the north and south sides of the step-up transformer module.

[0045] like Figure 5As shown, the fourth floor of the fusion platform 3 is the middle floor of the step-up substation module, and its layout is basically the same as the first floor of the substation functional area. The main plant in the middle area is mainly equipped with a radiator area a41, a42 above the main transformer room, a43 for 220kV diesel engine room, a44 for daily oil tank room, a45 for substation diesel engine, a46 for battery room, a47 for GIS room, a48 for HVAC room, and a49 for relay protection room. The hydrogen storage area b901 and the fourth-floor staircase b41 are arranged on both sides of the auxiliary plant. Among them, the power generation equipment is installed in the 220kV diesel engine room a43, and cooperates with the daily oil tank room a44. In addition, two sets of power generation equipment are set up, so that two sets of 220kV diesel engine room a43 and daily oil tank room a44 with backup power supply for each other are set up on the fourth floor of the fusion platform 3. This can solve the power supply problem in the event of an unexpected power outage, avoid adverse situations such as damage to hydrogen production and hydrogenation equipment due to accidental power outages, and have a high degree of reliability; the functions of the remaining rooms are the same as those of the existing offshore substation platform function rooms.

[0046] like Figure 6 As shown, the fifth floor of the fusion platform 3 serves as the roof layer of the step-up substation module. In addition to the uniformly arranged escape passage 11 and outdoor inclined ladder, a crane 20 is also provided for hoisting and shifting of the entire station equipment and hoisting of the detachable hydrogen tank 14, and main transformer equipment maintenance cover a51, 220kV diesel generator maintenance cover a52, GIS maintenance cover a53 and diesel generator maintenance cover a54 are provided for maintenance of the main equipment in the step-up substation module when necessary.

[0047] like Figure 7 and Figure 8 As shown, the main plant in the middle area between the first and second floors of the fusion platform 3 adopts an elevated floor 15, underneath which the incoming and outgoing cables, hydrogen pipelines 9 and cooling water pipes 10 required for the cabinets are laid; the main plant in the middle area is provided with a suspended ceiling 16, inside which ventilation ducts, bridges, and fire-fighting pipelines can be reserved, and then connected to the cable shaft b6 for collection and transfer; the entire station adopts fixed railings 17, which cannot be removed throughout the entire life cycle, and the other functional areas are consistent with the floor plan.

[0048] like Fig. 9 As shown, the detachable hydrogen tank 14 in this embodiment is placed in the open air, which is convenient for the crane 20 to carry out the lifting operation. The specific operation is that when the detachable hydrogen tank 14 needs to be transported, the detachable support 19 is opened, and the detachable hydrogen tank 14 is transported to the transport ship by the crane 20 with the help of the lifting lug 18.

[0049] The above embodiment is only a preferred technical solution of the present invention. Those skilled in the art should understand that the technical solutions or parameters in the embodiments can be modified or replaced without departing from the principle and essence of the present invention, and all should be included in the protection scope of the present invention.
