Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of offshore data centers, and in particular to a data center constructed on the same site as deep-sea wind power and photovoltaic power plants. Background Art
[0002] As one of the "new infrastructure", the big data center (IDC) is an important computing power component and data storage form in the Internet era. Building IDC on the sea or seabed has many advantages such as not occupying land indicators, low heat dissipation cost, and being close to the user center, but the power supply, construction and operation and maintenance costs are high, and it is difficult to independently have the benefits of large-scale promotion. So far, IDC has been integrated with offshore booster stations or offshore converter stations in offshore wind power, trying to achieve several benefits such as three-dimensional intensive use of the sea, on-site use of electricity, and integration of fire protection and HVAC systems. However, it should be noted that one of the key requirements for the stable operation of IDC is to have a backup redundant power supply and system loop, and city power can be used when it is close to the shore. However, with the requirements of offshore wind power, new offshore wind farms must meet the requirements of 30km offshore or 30m water depth. In this case, even if IDC is integrated with offshore wind power, in addition to the shared parts with offshore wind power, the length of the data optical cable and city power cable required as redundancy and backup will increase, which will greatly increase the cost and lose economic efficiency.
[0003] In summary, it is necessary to improve the existing technical solutions for the integration of offshore wind power and IDC, and to find a deep-sea offshore wind power industry integration that enables it to have a "2N" power supply and signal transmission circuit and meet the requirements of economic indicators, so as to promote the real implementation of the conversion of electricity into computing power.

DETAILED DESCRIPTION
[0023] 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.
[0024] like Figure 1-3 As shown, a data center is built on the same site as deep-sea wind power and photovoltaic power generation. Floating wind turbines 1 and floating photovoltaic power generation 2 are arranged in a row in the wind power and photovoltaic power generation field. Navigation channels are reserved between the floating wind turbines 1 and the floating photovoltaic power generation 2 and between each other. The floating wind turbines 1 are arranged according to the maximum utilization hours of wind energy and the minimum sea area, so as to realize the conversion of wind energy into electrical energy. The floating photovoltaic power generation 2 is arranged on the side with a larger spacing between the floating wind turbines 1, which is usually the wake influence area, so as to realize the conversion of light energy into electrical energy. A submarine big data center 4 is set on the seabed surface below the floating photovoltaic power generation 2. An offshore booster station / converter station 3 is also set in the wind power and photovoltaic power generation field. The floating wind turbines 1 and the floating photovoltaic power generation 2 are converted and stabilized by the equipment in their respective blocks in the offshore booster station / converter station 3 and then connected to the submarine big data. The center 4 is electrically connected, and an energy storage device is installed in the offshore booster station / converter station 3 to form a power supply with redundant power sources for the floating wind turbine 1 and the floating photovoltaic 2, thereby ensuring the stable and reliable operation of the submarine big data center 4; the computing power generated by the submarine big data center 4 is transmitted to the offshore booster station / converter station 3 through the data cable 41, and the data is simply processed and collected on the optoelectronic composite cable 51 for unified external transmission. A land-based control center 5 is set up on the shore, and the optoelectronic composite cable 51 is connected between the land-based control center 5 and the offshore booster station / converter station 3. The offshore booster station / converter station 3 can synchronously transmit electric energy and data through the optoelectronic composite cable 51. Therefore, the land-based control center 5 is used for the voltage reduction and conversion of electric energy to access the power grid and the storage and management of computing power data, and at the same time plays a full-field monitoring and long-term operation and maintenance function.
[0025] In this embodiment, the offshore booster station / converter station 3 is arranged in parallel with the floating wind turbine 1 to ensure the regularity and navigation convenience within the wind power photovoltaic field; Figure 1 As shown in the figure, two rows of floating wind turbines 1 and one row of floating photovoltaics 2 are arranged in the wind power photovoltaic field, and the offshore booster station / converter station 3 is arranged in the middle of the floating wind turbine 1 array relatively closer to the onshore control center 5, so as to better integrate and connect the arranged floating wind turbines 1 and the floating photovoltaics 2.
[0026] On the basis of the above contents, one function of the offshore booster station / converter station 3 is to boost and convert most of the electric energy generated by the floating wind turbine 1 and the floating photovoltaic 2 and send it to the onshore centralized control center 5; the second function is to use the transformer and voltage stabilization facilities equipped thereon to convert and stabilize the remaining electric energy and then connect it to the submarine big data center 4, so that the voltage of the first power supply provided by the floating wind turbine 1 and the second power supply provided by the floating offshore photovoltaic 2 can meet the needs of the submarine big data center 4 in a timely and stable manner.
[0027] In this embodiment, the floating wind turbine 1 and the floating photovoltaic 2 form a "2N" complementary power supply of wind power N lines + photovoltaic N lines, wherein the electricity generated by the floating wind turbine 1 is transmitted to the offshore booster station / converter station 3 through a dynamic submarine cable, and serves as the main power supply of the submarine big data center 4. The electricity generated by the floating photovoltaic 2 is also transmitted to the offshore booster station / converter station 3 through a dynamic submarine cable, and the photovoltaic power conversion area 34 is equipped with an energy storage device adapted to the photovoltaic power capacity. Therefore, the floating photovoltaic 2 and the energy storage device together serve as redundant power supplies for the submarine big data center 4.
[0028] Among them, the upper block of the offshore booster station / converter station 3 is divided into wind turbine power conversion area 33 and photovoltaic power conversion area 34, which mainly convert and stabilize the electricity generated by the wind turbine 1 and photovoltaic 2 to adapt it to the power supply voltage requirement of the submarine big data center 4; accordingly, the floating wind turbine 1 is provided with a first collection line 11 connected to the wind turbine power conversion area 33, the submarine big data center 4 is provided with a first transmission cable 31 connected to the wind turbine power conversion area 33, the floating photovoltaic 2 is provided with a second collection line 21 connected to the photovoltaic power conversion area 34, and the submarine big data center 4 is provided with a second transmission cable 32 connected to the photovoltaic power conversion area 34.
[0029] The upper block of the offshore booster / converter station 3 is provided with a main substation 36, which is the main substation for wind and solar power, and increases the electric energy of each part to a certain voltage level for full-field transmission. The upper block of the offshore booster / converter station 3 is provided with a data processing center 35, and the submarine big data center 4 is connected to the data processing center 35 via a data cable 41. The data processing center 35 mainly supports and manages the computing power formed by the submarine big data center 4.
[0030] like Figure 3 As shown, in this embodiment, the optoelectronic composite cable 51 is provided with a conductor 511 and a data optical fiber 512 inside its outer protective layer, and the data optical fiber 512 is distributed around the conductor 511. In this embodiment, the large-capacity optoelectronic composite cable 51 is composed of 3 conductors 511 and data optical fibers 512. The data optical fibers 512 are determined according to the maximum computing power planned by the data processing center 35, and usually 10 data optical fibers 512 are provided inside. The large-capacity optoelectronic composite cable 51 is different from the existing submarine cable that can only transmit electrical energy. The large-capacity optoelectronic composite cable 51 can simultaneously transmit electrical energy and computing power data, so that the data cable and the submarine cable do not need to be laid separately, that is, the area of the submarine corridor is saved, and less sea is used; at the same time, the laying of the submarine cable can be completed simultaneously, and the construction cost is lower.
[0031] like Figure 1As shown, in this embodiment, two optoelectronic composite cable 51 loops are set on the path between the onshore centralized control center 5 and the offshore booster station / converter station 3, which are laid, landed and connected to the onshore centralized control center 5 on two different paths that are far apart. Since the two loops are backed up by each other, the reliable output of electric energy and computing power can be effectively guaranteed.
[0032] like Figure 2 As shown, the lower part of the offshore booster / converter station 3 adopts a fixed conductor frame, which is convenient for the access and delivery of submarine cables with different functions in the field area. At the same time, the fixed conductor frame has better vibration resistance, which is conducive to the long-term stable operation of the upper module equipment. At the same time, a mooring system 6 is set at the bottom of the floating wind turbine 1 and the floating photovoltaic 2. The floating wind turbine 1 is constrained to the seabed through the mooring system 6, and the floating photovoltaic 2 can be constrained to the seabed or the conductor frame of the offshore booster / converter station 3 through the mooring system 6.
[0033] Based on the above, the submarine big data center 4 on the seabed below the floating photovoltaic 2 does not need additional land acquisition, but has a large sea area, can accommodate more cabinets, and is exposed to lower seawater temperature, which can further reduce the PUE of the submarine big data center 4. At the same time, the submarine big data center 4 can also serve as a bottom anchoring facility for the floating photovoltaic 2, reducing the drifting motion of the floating array and reducing the cost of the mooring system 6.
[0034] 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.
