Description

Technical Field

[0001] This disclosure relates to floating offshore power generation devices. Background Technology

[0002] Wind power generation converts wind energy into mechanical energy to generate electricity and is receiving much attention as a clean energy source for reducing greenhouse gas emissions.

[0003] Wind power generation equipment is mainly installed on land, but due to increasing demand, it is increasingly being installed at sea to address noise complaints and site acquisition issues.

[0004] One type of offshore wind power generation device is the floating offshore wind turbine, which generates electricity while floating in water. Floating wind turbines are less restricted by water depth, allowing them to be easily installed in deep-sea areas and utilizing strong winds to enhance power generation efficiency. A floating offshore wind turbine consists of a power generation unit located in the upper section and a substructure located in the lower section to support the power generation unit while floating at sea.

[0050] Figure 1 This is a perspective view of a floating wind power generation device according to an embodiment. Figure 2 This is a view showing the floating body separated from the floating wind power generation device according to an embodiment. Figure 3 This is a plan view showing the floating body separated from the floating wind power generation device according to the embodiment.

[0051] Reference Figure 1 The floating wind power generation device 1 may include a power generation unit 2 configured to perform wind power generation and a floating body 3 configured to support the power generation unit 2.

[0052] The power generation unit 2 may include a tower 2a, a nacelle 2b mounted on the upper part of the tower 2a, and a rotor 2c connected to the rotation shaft of the nacelle 2b. The nacelle 2b may be configured to rotate mechanically using wind power and include a generator. The power generation unit 2 can perform power generation when the rotor 2c, which rotates by wind, is actuated to generate power.

[0053] The floating body 3 can be configured to float on water. The floating body 3 can be configured to support the power generation unit 2 when floating on water.

[0054] The floating body can be constructed in various shapes. In the case of a semi-submersible type, it can be divided into a centrally arranged floating body and an eccentrically arranged floating body. In a centrally arranged floating body, three pillars are arranged corresponding to the vertices of a triangle, and the power generation unit is installed in the central part of the pillars. In an eccentrically arranged floating body, similarly, three pillars are arranged corresponding to the vertices of a triangle, and the power generation unit is installed on any one of the pillars.

[0055] According to the implementation, the floating body 3 can be an eccentrically arranged floating body. The floating body can include multiple columns. For example, the floating body 3 can include three columns 3a, 3b, and 3c arranged at equal distances from each other, and the power generation unit 2 can be installed on any one of these three columns 3a, 3b, and 3c. For example, as Figure 1 As shown, the power generation unit 2 can be installed on the main column 3a.

[0056] Reference Figures 1 to 3 The floating body 3 may include a main column 3a and a plurality of auxiliary columns arranged at approximately equal distances.

[0057] Multiple auxiliary columns may include a first auxiliary column 3b and a second auxiliary column 3c. The main column 3a, the first auxiliary column 3b, and the second auxiliary column 3c may be arranged at positions corresponding to the vertices of a triangle. For example, the main column 3a, the first auxiliary column 3b, and the second auxiliary column 3c may be arranged at positions corresponding to the vertices of an equilateral triangle. In this case, the first distance between the main column 3a and the first auxiliary column 3b, the second distance between the first auxiliary column 3b and the second auxiliary column 3c, and the third distance between the second auxiliary column 3c and the main column 3a may be equal to each other. As described above, the power generation unit 2 may be installed on the main column 3a.

[0058] In another embodiment, the plurality of auxiliary columns may include three or more auxiliary columns. For example, the plurality of auxiliary columns may include a first auxiliary column and a second auxiliary column adjacent to the main column, and a third auxiliary column disposed between the first and second auxiliary columns. In this case, the first to third auxiliary columns may be arranged to be positioned on an imaginary circumference. Alternatively, the plurality of auxiliary columns may include four or more auxiliary columns arranged to be positioned on an imaginary circumference together with the main column.

[0059] In the following description, the case of multiple auxiliary columns, including the first auxiliary column 3b and the second auxiliary column 3c, will be used as an example.

[0060] The floating body 3 may include a connecting member 30 connecting the main column 3a, the first auxiliary column 3b, and the second auxiliary column 3c.

[0061] The connecting member 30 may include a first connecting member 31 connecting the main column 3a and the first auxiliary column 3b, a second connecting member 32 connecting the main column 3a and the second auxiliary column 3c, and a third connecting member 33 connecting the first auxiliary column 3b and the second auxiliary column 3c. The first connecting member 31, the second connecting member 32, and the third connecting member 33 may be arranged to correspond to each side of a triangle. For example, the first connecting member 31, the second connecting member 32, and the third connecting member 33 may be arranged to correspond to each side of an equilateral triangle.

[0062] In another embodiment, the first connecting member 31 and the second connecting member 32 may have the same length, but the third connecting member 33 may have a longer or shorter length than the first connecting member 31 and the second connecting member 32, thereby being arranged to correspond to each side of an isosceles triangle.

[0063] In another embodiment, the first connecting member 31 and the second connecting member 32 may be configured as linear, but the third connecting member 33 may be configured as a form that bends outward in a convex manner from a certain region.

[0064] As described above, in embodiments where the number of auxiliary columns is three or more, the number of connecting members 30 can be increased accordingly.

[0065] In embodiments with three or more auxiliary columns, the multiple connecting members 30 that connect the auxiliary columns to other adjacent auxiliary columns can be bent to form an approximately arcuate shape relative to each other. In such embodiments, the multiple connecting members 30 can provide more distributed support for external forces, thereby improving the support capacity of the auxiliary columns.

[0066] The connecting member 30 can be configured in various shapes. For example, the connecting member 30 can be configured as follows: Figure 1 The connecting member 30 is shown in the form of a tube with a rectangular cross-section, or alternatively, it can be configured as a tube with a circular, elliptical, or polygonal cross-section. Furthermore, the connecting member 30 can be hollow to improve buoyancy, or it can be formed as a single piece with a solid internal structure to provide stronger support against external forces. The connecting member 30 can be appropriately selected based on external factors such as wind speed, tidal forces, and seawater temperature in the sea where it is installed.

[0067] The connecting member 30 prevents the main column 3a, the first auxiliary column 3b, and the second auxiliary column 3c from moving away from or closer to each other, and ensures the structural stability of the floating body 3. The connecting member 30 also prevents damage to the floating body 3 from vibrations or impacts applied to it at sea.

[0068] According to an embodiment, the floating body 3 may include a pontoon 4 disposed below the connecting member 30 relative to the direction of gravity.

[0069] In one embodiment, the float 4 may include a first float 4a connected to the main post 3a, a second float 4b connected to the first auxiliary post 3b, and a third float 4c connected to the second auxiliary post 3c. The float 4 may extend from the region between the main post 3a, the first auxiliary post 3b, and the second auxiliary post 3c to the main post 3a, the first auxiliary post 3b, and the second auxiliary post 3c. For example, the float 4 may extend from the central portion between the main post 3a, the first auxiliary post 3b, and the second auxiliary post 3c to the main post 3a, the first auxiliary post 3b, and the second auxiliary post 3c.

[0070] One end of the first buoy 4a can be connected to the main post 3a, and the other end of the first buoy 4a can be connected to the second buoy 4b and the third buoy 4c. One end of the second buoy 4b can be connected to the first auxiliary post 3b, and the other end of the second buoy 4b can be connected to the first buoy 4a and the third buoy 4c. One end of the third buoy 4c can be connected to the second auxiliary post 3c, and the other end of the third buoy 4c can be connected to the first buoy 4a and the second buoy 4b. In other words, the first buoy 4a, the second buoy 4b, and the third buoy 4c can be configured to be connected to each other.

[0071] According to this disclosure, the pontoon 4 can be configured in an approximately Y-shaped form. Based on the Y-shaped pontoon 4, the sum of the lengths of the first pontoon 4a, the second pontoon 4b, and the third pontoon 4c can be less than the sum of the lengths of the first connecting member 31, the second connecting member 32, and the third connecting member 33. According to this disclosure, the length of the pontoon 4 can be reduced by configuring its structure to have an approximately Y-shaped form. This can reduce the manufacturing cost of the floating wind power generation device.

[0072] Furthermore, the pontoons 4 can be configured in a Y-shape, which improves the ease with which a vessel can approach the floating wind turbine 1. When the pontoons 4 are configured in a Y-shape, the vessel can approach up to the point where the pontoons 4 meet. Therefore, compared to a structure where the pontoons 4 are arranged in the same manner as the connecting member 30, the ease with which a vessel can approach is improved.

[0073] Reference Figure 2The floating body 3 according to the embodiment may include a ballast space configured to be filled with ballast water. The floating body 3 may include a column receiving portion and a buoy receiving portion as the ballast space configured to receive ballast water.

[0074] Specifically, the floating body 3 may include a main column receiving portion 34 formed inside the main column 3a, a first auxiliary column receiving portion 35 formed inside the first auxiliary column 3b, and a second auxiliary column receiving portion 36 formed inside the second auxiliary column 3c. Additionally, the floating body 3 may include a first float receiving portion 41 formed inside the first buoy 4a, a second float receiving portion 42 formed inside the second buoy 4b, and a third float receiving portion 43 formed inside the third buoy 4c.

[0075] According to the implementation method, such as Figure 2 As shown, the first pontoon receiving portion 41, the second pontoon receiving portion 42, and the third pontoon receiving portion 43 can form separate spaces from each other. In other words, the first pontoon receiving portion 41, the second pontoon receiving portion 42, and the third pontoon receiving portion 43 can be not connected to each other.

[0076] According to one embodiment, the first buoy receiving portion 41 can be connected to the main column receiving portion 34. The second buoy receiving portion 42 can be connected to the first auxiliary column receiving portion 35. The third buoy receiving portion 43 can be connected to the second auxiliary column receiving portion 36.

[0077] Alternatively, at least two of the first pontoon receiving portion 41, the second pontoon receiving portion 42, and the third pontoon receiving portion 43 may be connected. For example, the first pontoon receiving portion 41, the second pontoon receiving portion 42, and the third pontoon receiving portion 43 may be connected to each other. Alternatively, the second pontoon receiving portion 42 and the third pontoon receiving portion 43 may be connected to each other, and the first pontoon receiving portion 41 may not be connected to the second pontoon receiving portion 42 and the third pontoon receiving portion 43.

[0078] Furthermore, the first buoy receiving portion 41 and the main column receiving portion 34 may not be connected to each other. Similarly, the second buoy receiving portion 42 and the first auxiliary column receiving portion 35 may not be connected to each other. The third buoy receiving portion 43 and the second auxiliary column receiving portion 36 may not be connected to each other.

[0079] and Figure 2 As shown, the main column 31 may not include a ballast space because the main column 3a is configured to support the power generation unit 2. In other words, the main column 3a may not include the main column receiving portion 34.

[0080] Figure 3 This is a plan view showing the floating body separated from the floating wind power generation device according to an embodiment.

[0081] Figure 4 This is a plan view of the columns and pontoons in a floating wind power generation device according to an embodiment.

[0082] Reference Figure 4 In the floating wind power generation device according to the embodiment, the first buoy 3a, the second buoy 3b and the third buoy 3c may have the same length as each other.

[0083] Reference Figure 4 The diameter of the main column 3a is called the first diameter d1, the diameter of the first auxiliary column 3b is called the second diameter d2, and the diameter of the second auxiliary column 3c is called the third diameter d3.

[0084] According to the embodiment, the first diameter d1, the second diameter d2, and the third diameter d3 can be the same. However, this disclosure is not limited thereto. The first diameter d1, the second diameter d2, and the third diameter d3 can be different from each other. In addition, two of the first diameter d1, the second diameter d2, and the third diameter d3 can be the same, and the remaining one can be different. For example, the first diameter d1 can be larger than the second diameter d2 and the third diameter d3, and the second diameter d2 and the third diameter d3 can be the same. The first diameter d1 of the main column 3a can be set to be larger than the second diameter d2 and the third diameter d3 in order to support the power generation unit 2.

[0085] Reference Figure 4 The length of the first pontoon 41 is referred to as the first length PL1, the length of the second pontoon 42 is referred to as the second length PL2, and the length of the third pontoon 43 is referred to as the third length PL3. Additionally, the width of the first pontoon 41 is referred to as the first width PW1, the width of the second pontoon 42 is referred to as the second width PW2, and the width of the third pontoon 43 is referred to as the third width PW3.

[0086] According to the implementation method, the first length PL1, the second length PL2, and the third length PL3 can be set to be the same. Additionally, the first width PW1, the second width PW2, and the third width PW3 can be set to be the same.

[0087] and Figure 4 Conversely as shown, the first length PL1, the second length PL2, and the third length PL3 can be set to be different from each other. The first width PW1, the second width PW2, and the third width PW3 can also be set to be different from each other.

[0088] The main column 3a can support the power generation unit 2 and therefore can have a larger load than the first auxiliary column 3b and the second auxiliary column 3c. To balance the floating wind turbine 1 as a whole, ballast water can be filled into the first auxiliary column 3b and the second auxiliary column 3c. However, when ballast water is only filled into the first auxiliary column 3b and the second auxiliary column 3c, the center of gravity (COG) of the floating wind turbine 1 may be relatively high, which could lead to a reduction in its ability to maintain balance at sea.

[0089] According to this disclosure, ballast water can be filled not only in the first auxiliary column 3b and the second auxiliary column 3c, but also in the first pontoon receiving portion 41, the second pontoon receiving portion 42, and the third pontoon receiving portion 43. Specifically, by filling the second pontoon receiving portion 42 and the third pontoon receiving portion 43 with ballast water, the COG of the floating wind turbine 1 can be reduced. This can improve the balance recovery capability of the floating wind turbine 1 at sea. In other words, the dynamic motion performance of the floating wind turbine 1 can be improved.

[0090] According to this disclosure, the length PL1 of the first pontoon 4a, the length PL2 of the second pontoon 4b, and the length PL3 of the third pontoon 4c can be changed to improve the dynamic motion performance of the floating wind power generation device 1. Additionally, the width PW1 of the first pontoon 4a, the width PW2 of the second pontoon 4b, and the width PW3 of the third pontoon 4c can be changed to improve the dynamic motion performance of the floating wind power generation device 1.

[0091] Figure 5 This is a plan view of the columns and pontoons in a floating wind power generation device according to an embodiment.

[0092] Reference Figure 5 In the floating wind power generation device according to the embodiment, the first length PL1 of the first pontoon 3a can be set to be greater than the second length PL2 of the second pontoon 3b and the third length PL3 of the third pontoon 3c. Alternatively, the second length PL2 of the second pontoon 3b and the third length PL3 of the third pontoon 3c can be set to be the same.

[0093] exist Figure 5 The example shown illustrates that the first width PW1, the second width PW2, and the third width PW3 are set to be the same. However, as mentioned above, the first width PW1, the second width PW2, and the third width PW3 can be set to be different from each other, or only one of the first width PW1, the second width PW2, and the third width PW3 can be set to be different. For example, the second width PW2 and the third width PW3 can be set to be the same, and the first width PW1 can be set to be greater than or less than the second width PW2 and the third width PW3.

[0094] Figure 6This is a plan view of the columns and pontoons in a floating wind power generation device according to an embodiment.

[0095] Reference Figure 6 In the floating wind power generation device according to the embodiment, the first length PL1 of the first pontoon 3a can be set to be shorter than the second length PL2 of the second pontoon 3b and the third length PL3 of the third pontoon 3c. The second length PL2 of the second pontoon 3b and the third length PL3 of the third pontoon 3c can be set to be the same.

[0096] exist Figure 6 The example shown illustrates that the first width PW1, the second width PW2, and the third width PW3 are set to be the same. However, as mentioned above, the first width PW1, the second width PW2, and the third width PW3 can be set to be different from each other, or only one of the first width PW1, the second width PW2, and the third width PW3 can be set to be different. For example, the second width PW2 and the third width PW3 can be set to be the same, and the first width PW1 can be set to be greater than or less than the second width PW2 and the third width PW3.

[0097] As described above, according to this disclosure, the length PL1 and width PW1 of the first float 4a, the length PL2 and width PW2 of the second float 4b, and the length PL3 and width PW3 of the third float 4c can be adjusted individually. By individually adjusting the length and width of the first float 4a, the second float 4b, and the third float 4c, the kinematic performance of the floating body 2 can be optimized.

[0098] Furthermore, although not specifically shown in the accompanying drawings, the heights of the first pontoon 4a, the second pontoon 4b, and the third pontoon 4c can be adjusted individually. By adjusting the heights of the first pontoon 4a, the second pontoon 4b, and the third pontoon 4c individually, the kinematic performance of the floating body 2 can be optimized.

[0099] As described above, by forming the first pontoon 4a, the second pontoon 4b, and the third pontoon 4c to extend from the region located inside the main column 3a, the first auxiliary column 3b, and the second auxiliary column 3c to each column, interference between the lower portion of the vessel approaching the floating wind power generator 1 and the floating body 2 can be minimized. In other words, the pontoon 4 can be configured in an approximately Y-shaped form to minimize interference between the lower portion of the vessel approaching the floating wind power generator 1 and the floating body 2.

[0100] Although specific embodiments have been illustrated and described above, this disclosure is not limited to the above embodiments, and those skilled in the art can make various changes and modifications without departing from the spirit of the invention as described in the appended claims.
