Description

Floating Wind Power Generation Apparatus and Method for Buoyancy Compensating

The present invention relates to a floating wind turbine and a buoyancy compensation method thereof.

BACKGROUND ART Techniques for offshore wind power generation that install windmills on offshore with abundant wind volume have been in the spotlight in the technology of providing renewable power by introducing renewable energy. For example, in the UK, large-scale offshore wind power plans are being implemented in preparation for the risk of depletion of North Sea oil fields where crude oil production is decreasing.

There are two types of offshore wind power: the concept of fixing the parts of the windmill at sea and the floating of windmills on buoys floating on the sea. Ideas are suitable for relatively shallow depths, while floating is suitable for deep depths. This is because, in the case of installing a floating offshore wind turbine on a deep coast, the cost for fixing the generator increases, and stability is not guaranteed.

On the other hand, when a portion of the existing floating wind generators located below the sea level is damaged, the floating wind generators gradually sink as the sea water is obtained as the floating wind generators. As a result, the floating wind generator may lose its original power generation function.

According to an exemplary embodiment of the inventive concept, when damage occurs to a portion of the floating wind turbine and the seawater fills up, the floating wind turbine sinks and prevents or compensates for the loss of wind power generation. To provide a floating wind turbine and a buoyancy compensation method thereof.

According to another exemplary embodiment of the inventive concept, a floating wind turbine generator may include a buoyancy unit divided into a plurality of buoyancy regions; A load part partitioned into a plurality of load areas for fixing the floating wind power generator; A sensing unit sensing whether the buoyancy regions are damaged; And a controller for separating at least one of the load regions when at least one of the damaged buoyancy regions occurs as a result of the sensing unit sensing.

The load regions may be connected to each other by a fastening part that is detachable by a command of the controller.

The fastening part may be blown up by a command of the controller.

When the density ratio of seawater and the load portion is 1: n, the volume ratio between the buoyancy region and the load region may be 1: 1 / n.

The controller may separate the load region by the number of the damaged buoyancy regions.

On the other hand, according to another exemplary embodiment of the inventive concept, the floating wind power generation device includes a load portion partitioned into a plurality of load regions; A sensor for sensing the degree of submersion of the floating wind power generator; And a controller configured to separate at least one of the load regions when the degree of the water submersion is outside a preset threshold.

The apparatus may further include a buoyancy portion partitioned into a plurality of buoyancy regions. When the density ratio of seawater and the load portion is 1: n, the volume ratio between the buoyancy region and the load region may be 1: 1 / n. .

Meanwhile, according to another exemplary embodiment of the present inventive concept, a buoyancy compensation method of a floating wind power generator including a buoyancy part and a load part may include partitioning the buoyancy part into a plurality of buoyancy regions; Partitioning the load into a plurality of load regions; Determining whether the buoyancy regions are damaged; And if it is determined that there is at least one damaged buoyancy region among the buoyancy regions, separating at least one of the load regions.

The plurality of load regions are each connected by a detachable fastening portion, and the fastening portion is blastable.

In the separating step, the load region may be separated by the number of the damaged buoyancy regions.

Meanwhile, according to another exemplary embodiment of the inventive concept, a buoyancy compensation method in a floating wind power generator including a load unit may include partitioning the load unit into a plurality of load regions; Sensing the degree of submersion of the floating wind power generator; And dividing at least one of the regions when the degree of the submersion is out of a predetermined threshold value.

The method may further include partitioning the buoyancy portion of the floating wind power generator into a plurality of buoyancy regions. When the density ratio of seawater and the load portion is 1: n, the volume ratio between the buoyancy region and the load region is 1. It may be: 1 / n.

According to one or more exemplary embodiments of the present inventive concept, when damage occurs inside a floating wind turbine to obtain seawater, one of the regions responsible for the load is separated in consideration of the density of the seawater. This effectively and quickly prevents or compensates for the floating wind turbine's sinking and losing its wind turbine role.

1 is a diagram illustrating a first floating wind turbine generator 100 according to a first exemplary embodiment of the inventive concept.

The first floating wind power generator 100 illustrated in FIG. 1 may include a wind generator 110, a body 120, and a control panel 130.

The wind power generator 110 is installed on the wings 111 rotatably installed by the wind, the pillar 113 installed on the body 120 and the upper portion of the pillar 113, and the rotating shaft of the wings 111 and the generator are built in. May include a generator housing 112. The wind power generator 110 has a structure supported by the body 120.

A portion of the body 120 may be installed in the form of floating on the sea level or submerging the entire body 120 below the sea level. The body 120 may include a buoyancy portion 121, a central portion 122, and a load portion 123.

The buoyancy portion 121 is divided into a plurality of buoyancy regions, the body 120 may be filled with a gas such as air so as not to sink into the sea. When the buoyancy portion 121 is not divided into a plurality of buoyancy regions, when the buoyancy portion 121 is damaged or seawater is introduced into the buoyancy portion 121 by an external wound, the entire buoyancy portion 121 is closed. It will not be able to play a role for buoyancy. The plurality of buoyancy regions will be described using the first to fifth buoyancy regions 211, 212, 213, 214, and 215 illustrated in FIG. 2 as an example.

In order to prevent such a problem, in the exemplary embodiment of the present invention, the buoyancy portion 121 may be divided into first to fifth buoyancy regions 211 to 215. The first to fifth buoyancy regions 211 to 215 may be divided in consideration of the density of the load portion 123, the density of seawater, and the volume of the buoyancy region. This will be described in detail with reference to FIG. 2.

The central portion 122 may be provided to prevent the body 120 from being inclined by waves or wind and to hold the center of the body 120. Ropes 140 may be provided on the outer surface of the central portion 122 to connect the central portion 122 and the sea bottom. The body 120 may be supported by the ropes 140 and fixed to the sea bottom. The interior of the central portion 122 may be filled with water, which is not limited thereto as an example.

The load portion 123 is partitioned into a plurality of load regions, and may be formed of a material such that the body 120 does not completely float above the sea level. The material forming the load part 123 is, for example, concrete, which is not limited thereto. The plurality of load regions will be described by taking first to fifth load regions 221, 222, 223, 224, and 225 shown in FIG. 2 as an example.

The first to fifth load regions 221 to 225 have a damaged buoyancy region among the first to fifth buoyancy regions 211 to 215, and when the seawater enters into the damaged buoyancy region, the body In order to prevent the 120 from sinking to the sea, it may have a structure in which at least one or more load zones are separated at the same time. Therefore, the number of first to fifth load regions 221 to 225 may be equal to or greater than the number of first to fifth buoyancy regions 211 to 215 as shown in FIG. 2.

2 is a view for explaining in detail the buoyancy portion 121 and the load portion 123 according to the first exemplary embodiment of the inventive concept.

Referring to FIG. 2, the buoyancy portion 121 is divided into first to fifth buoyancy regions 211 to 215. Inside the first to fifth buoyancy regions 211 to 215 may be filled with a gas such as air. In addition, the load unit 123 is partitioned into first to fifth load regions 221 to 225, and the first to fifth load regions 221 to 225 may be made of a material having a large load such as concrete. Can be.

The first to fifth load regions 221 to 225 may be connected by the first to fifth fastening portions 221a to 221e, respectively. The first to fifth fastening parts 221a to 221e may be separated by a command of the controller 132. For example, the first to fifth fastening parts 221a to 221e may be automatically detonated. Alternatively, when the first to fifth fastening parts 221a to 221e connect the first to fifth load regions 221 to 225 in a ring shape, the first to fifth fastening parts 221a to 221e may be formed. You can disconnect the rings.

In the first exemplary embodiment of the inventive concept, when the density ratio of seawater and load portion 123 is 1: n (where n is positive) in the same volume, buoyancy portion 121 and load portion 123 The volume ratio of the liver may be designed and installed to be 1: 1 / n. In addition, when the density ratio of the seawater and the load portion 123 is 1: n at the same volume, the volume ratio between the first buoyancy region 211 and the first load region 221 is designed and installed to be 1: 1 / n. Can be.

In the latter case, the first to fifth buoyancy regions 211 to 215 are partitioned to have the same first volume, and the first to fifth load regions 221 to 225 have the same second volume. do. That is, when the volume of the first buoyancy region 211 is v1 and the volume of the first load region 221 is w1, v1: w1 = 1: 1 / n.

Meanwhile, first to fifth sensors 211a to 215e may be communicatively connected to the first to fifth buoyancy regions 211 to 215, respectively. The first to fifth sensors 211a to 215e may sense an internal state necessary to determine whether the first to fifth buoyancy regions 211 to 215 are damaged. For example, the first sensor 211a senses the density of seawater in the first buoyancy region 211 when the first buoyancy region 211 is damaged and water enters the first buoyancy region 211. Alternatively, the height of seawater obtained in the first buoyancy region 211 may be sensed. The first sensor 211a may transmit a result of the sensed internal state of the first buoyancy region 211 to the controller 132.

In FIG. 2, although the first to fifth sensors 211a to 215e are connected to each of the first to fifth buoyancy regions 211 to 215, one sensor (not shown) is formed on the upper surface of the buoyancy portion 121. ) May be attached. In this case, the sensor (not shown) may sense the distance L between the sea level and the upper surface of the buoyancy unit 121, and may transmit the sensing result to the controller 132.

Referring back to FIG. 1, the control panel 130 senses and determines whether the buoyancy portion 121 is damaged in the body 120, and controls the separation of the load regions 221 ˜ 225 based on the determination result. Can be. To this end, the control panel 130 may include a sensing unit 131, a control unit 132, and a communication unit 133. Although FIG. 1 shows that the control panel 130 is installed separately from the body 120, this is for convenience of description, and the control panel 130 may be installed inside the body 120.

As illustrated in FIG. 2, the sensing unit 131 may include first to fifth sensors 211a to 215e attached to each of the first to fifth buoyancy regions 211 to 215. The first to fifth sensors 211a to 215e may sense an internal state of each of the first to fifth buoyancy regions 211 to 215 and transmit a sensing result to the controller 132.

The controller 132 analyzes the sensing result of the sensing unit 131 to determine whether there is a damaged buoyancy region among the first to fifth buoyancy regions 211 to 215, and if the damaged buoyancy region occurs at least one of the results, At least one of the first to fifth load regions 221 to 225 may be separated from the load part 123.

For example, when the result transmitted from the first sensor 211a is the density of seawater in the first buoyancy region 211, the controller 132 may control the first buoyancy when the density reaches or exceeds a preset threshold. It may be determined that the area 211 is damaged and the sea water is cold. In addition, the controller 132 separates the load area (for example, the first load area 221 located at the bottom) from the load part 123 whose volume is 1 / n of the volume of the first buoyancy area 211. You can do that.

Here, the threshold value may be smaller than the density of the seawater when the seawater in the first buoyancy region 211 is full. As described with reference to FIG. 2, in the present embodiment, when the volume ratio between the first buoyancy region 211 and the first load region 221 is 1: 1 / n, the density of seawater in the first buoyancy region 211 Since the density ratio between the first load region 221 and 1: n is installed, the threshold value may be less than one.

Alternatively, when the result transmitted from the first sensor 211a is the height of the seawater in the first buoyancy region 211, the density of seawater in the first buoyancy region 211 is calculated from the height, and the calculated density is previously determined. When the set threshold is reached or exceeded, it may be determined that the first buoyancy region 211 is damaged and the seawater is cold. The density of seawater in the first buoyancy region 211 can be easily calculated since the controller 132 knows the length, width, and height of the first buoyancy region 211. Therefore, when the volume ratio between the first buoyancy region 211 and the first load region 221 is 1: 1 / n, the controller 132 controls the density of the seawater in the first buoyancy region 211 and the first load region ( When it is determined that the density ratio 221 approaches 1: n or reaches 1: n, the first load region 221 may be separated from the load part 123.

In order to separate the first load region 221 from the load portion 123, the controller 132 may include a first fastening portion 221a connecting the first load region 221 and the second load region 222. The first fastening part 221a may be controlled to automatically separate the first load area 221. The first fastening part 221a may automatically detonate under the control of the controller 132 to separate the first load region 221. Alternatively, when the first fastening portion 221a has an annular shape that operates electronically, the first fastening portion 221a releases the ring connected to the first load region 221 under the control of the controller 132 to thereby release the first. The load region 221 may be separated.

The communication unit 133 may transmit a control signal of the control unit 132 to at least one of the first to fifth fastening units 221a to 221e. Examples of the control signal may be the above-described automatic blast command or disconnection.

For example, when the control unit 132 commands the first load region 221 to be separated, the communication unit 133 transmits a control signal related to the command to the first fastening unit 221a and the first fastening unit. 221a is automatically detonated by the control signal so that the first load region 221 is separated. As a result, a volume corresponding to the amount of seawater received in at least one of the first to fifth buoyancy regions 211 to 215 is separated from the load portion 123, and as a result, the body 120 is in an initial state. You can have 'Initial state' means that the portion of the load portion 123 is removed by the amount of water obtained by the buoyancy portion 121, which means that the distance between the body 120 and the sea level is maintained at an initial value.

3 is a view illustrating a second floating wind turbine 300 according to a second exemplary embodiment of the inventive concept.

The second floating wind power generator 300 illustrated in FIG. 3 may include a wind generator 310, a body 320, and a control panel 330. The wind power generator 310, the body 320, and the control panel 330 illustrated in FIG. 3 may be partially operated, configured, or operated with the wind power generator 110, the body 120, and the control panel 130 described with reference to FIG. 1. Since the functions are similar or identical, some descriptions may be omitted.

Wind power generator 310 is installed on top of the wings 311 rotatably installed by the wind, the pillar 313 and the pillar 313 installed on the body 320, the rotating shaft of the wings 311 and the generator is built-in May include a generator housing 312.

It may include a buoyancy portion 321, the central portion 322 and the load portion 323 of the body 320.

The buoyancy portion 321 is divided into a plurality of buoyancy regions, the body 320 may be filled with a gas such as air so as not to sink into the sea. The plurality of buoyancy regions will be described using the first to fifth buoyancy regions 411 to 415 illustrated in FIG. 4 as an example.

The central portion 322 may be provided to prevent the body 320 from being inclined by waves or wind and to hold the center of the body 320. Ropes 340 connecting the central portion 322 and the bottom surface may be provided on an outer surface of the central portion 322.

The load part 323 is partitioned into a plurality of load areas, and may be formed of a material that prevents the body 320 from fully floating above the sea level. The material constituting the load portion 323 is, for example, concrete, which is not limited thereto. The plurality of load regions will be described by taking the first to fifth load regions 421 to 425 illustrated in FIG. 4 as an example.

The first to fifth load regions 421 to 425 may have a damaged buoyancy region among the first to fifth buoyancy regions 411 to 415, and the seawater may be obtained into the damaged buoyancy region. In order to prevent the 320 from sinking into the sea, it may have a structure such that at least one or more load regions are separated at the same time.

4 is a view for explaining in detail the buoyancy portion 321 and the load portion 323 according to a second exemplary embodiment of the present invention concept.

Referring to FIG. 4, the buoyancy portion 321 is divided into first to fifth buoyancy regions 411 to 415. The interior of the first to fifth buoyancy regions 411 to 415 may be filled with a gas such as air. In addition, the load portion 323 is divided into first to fifth load regions 421 to 425, and the first to fifth load regions 421 to 425 may be made of a material having a large load such as concrete. Can be.

The first to fifth load regions 421 to 425 may be connected by the first to fifth fastening portions 421a to 421e, respectively. The first to fifth fastening parts 421a to 421e may be separated by a command of the controller 332.

As described with reference to FIG. 4, in the embodiment of the present invention, in the same volume, when the density ratio of the seawater and the load portion 323 is 1: n, the volume ratio between the buoyancy portion 321 and the load portion 323 is 1: 1 / n, or may be designed and installed so that the volume ratio between the m-th buoyancy region and the m-th load region is 1: 1 / n. m is one of 1, 2, 3, 4, and 5. For example, when the volume of the first buoyancy region 411 is v1 and the volume of the first load region 421 is w1, v1: w1 = 1: 1 / n.

Referring back to FIG. 3, the control panel 330 senses and determines whether the buoyancy portion 321 is damaged in the body 320, and controls the separation of the load regions 421 to 425 based on the determination result. Can be. To this end, the control panel 330 may include a sensing unit 331, a control unit 332 and a communication unit 333.

The sensing unit 331 may be provided on an upper surface of the fifth buoyancy region 415, that is, on an upper surface of the buoyancy unit 321. The sensing unit 331 may sense the degree to which the floating wind power generator 300 or the body 320 is submerged from the sea surface, that is, the distance L between the sea surface and the upper surface of the buoyancy unit 321. The sensing unit 331 may transfer the sensed result to the control unit 332.

The controller 332 analyzes the sensing result of the sensing unit 331 to determine whether there is a damaged buoyancy region among the first to fifth buoyancy regions 411 to 415, and determines that there is at least one damaged buoyancy region. When at least one of the first to fifth load regions 421 to 425 may be separated from the load unit 323.

In detail, the control unit 332 calculates an absolute value of the distance L between the buoyancy unit 321 and the sea level received from the sensing unit 331 and a predetermined threshold value, and calculates the calculated difference and the reference value table. By comparing this, it may be determined whether at least one of the first to fifth buoyancy regions 411 to 415 is damaged. In particular, the controller 332 may determine that a larger number of buoyancy regions 411 to 415 are damaged as the calculated difference increases, and allow one or more load regions to be separated. This means that the calculated difference is large because the body 320 is locked more from the sea level, and as a result, the amount of seawater obtained into the load portion 323 is large.

Table 1 shows an example of a reference value table used by the controller 332. The reference value table may be stored in a memory (not shown) allocated to the controller 332.

Absolute value of the difference between the distance (L) and the preset threshold (in meters) Load area to separate 0-3 - 1-4 1st load area 2 to 3 1st and 2nd load area 3 to 4 First to third load regions 4 to 5 First to fourth load regions 5 to 6 Fourth to fifth load regions

Referring to Table 1, if the absolute value of the difference between the distance L and the preset threshold is 1 m or more and less than 2 m, the controller 332 may include one buoyancy region (eg, a third buoyancy region ( 413)), it is determined that the seawater has been obtained, and one load region having a volume of 1 / n relative to the volume of the third buoyancy region 413 (for example, the first load region 421 at the bottom) Can be separated. In addition, when the absolute value of the difference between the distance L and the preset threshold is 4 m or more and less than 5 m, the controller 332 includes at least four buoyancy regions (for example, the first to fourth buoyancy regions 411). 414)), the four load regions (for example, the bottommost) having a volume of 1 / n relative to the volumes of the first to fourth buoyancy regions 411 to 414 The first to fourth load regions 411 to 414 may be separated.

When the control unit 332 needs to separate at least one load region, the controller 332 may separate the load region located at the bottom from the load unit 323. For example, the controller 332 connects the first load region 421 and the second load region 422 to separate the lowermost first load region 421 from the load portion 323. The first fastening part 421a may control the first fastening part 421a to automatically separate the first load region 421.

The communication unit 333 may transmit a control signal of the control unit 332 to at least one of the first to fifth fastening units 421a to 421e.

5 is a flowchart illustrating a buoyancy compensation method of the first floating wind power generator according to the first exemplary embodiment of the present inventive concept.

The first floating wind power generator for the buoyancy compensation method of FIG. 5 may be the first floating wind power generator 100 described with reference to FIG. 1.

Referring to FIG. 5, the first floating type wind power generator may divide the buoyancy portion into a plurality of buoyancy regions (S510).

In addition, the first floating wind turbine generator may divide the load into a plurality of load regions (S520). In steps S510 and S520, the buoyancy regions and the load regions are partitioned so that the volume ratio between one buoyancy region and one load region is 1: 1 / n when the density ratio of seawater and load portion is 1: n in the same volume. Can be.

The first floating type wind power generator may sense the internal state of the buoyancy regions to determine whether the buoyancy regions are damaged (S530). In operation S530, the first floating wind turbine generator may sense the density of the water obtained in each buoyancy region or the height of the obtained water.

The first floating type wind power generator may determine whether each of the buoyancy regions is damaged by analyzing the results sensed in operation S530 (SS540). In operation S540, when the first floating wind turbine generator compares the sensed result with a preset threshold value and the sensed result reaches or exceeds the threshold value, the corresponding buoyancy region is damaged and the seawater is buoyant. It can be judged that it was obtained.

If it is determined that at least one buoyancy region is damaged (S550-Y), at least one of the load regions may be separated from the load portion (S560). For example, if it is determined in step S550 that the first buoyancy region is damaged, in step S560 the first floating wind turbine generator may separate the load region at the bottom from the load portion. This means that when the density ratio of seawater and load part is 1: n in the same volume of buoyancy zones and load zones, the volume ratio between one buoyancy zone and one load zone is 1: 1 / n. This is because the mouth can maintain the initial balance even if only one load area is removed.

6 is a flowchart illustrating a buoyancy compensation method of the second floating wind power generator according to the second exemplary embodiment of the present inventive concept.

The second floating wind power generator for the buoyancy compensation method of FIG. 6 may be the second floating wind power generator 300 described with reference to FIG. 3.

Referring to FIG. 6, the second floating type wind power generator may divide the buoyancy part into a plurality of buoyancy regions (S610).

In addition, the second floating wind turbine generator may divide the load into a plurality of load regions (S620). In steps S610 and S620, the buoyancy regions and the load regions are partitioned so that the volume ratio between one buoyancy region and one load region is 1: 1 / n when the density ratio of seawater and load portion is 1: n in the same volume. Can be.

The second floating wind turbine can sense the degree of submersion of the buoyancy section or the second floating wind turbine submerged in water, that is, the distance L between the top surface of the buoyancy section and sea level. There is (S630).

The second floating type wind power generator may determine whether the buoyancy regions are damaged by analyzing the results sensed in operation S630.

In detail, the absolute value of the difference between the distance L sensed in the second floating wind turbine generator S630 and a preset threshold may be calculated (S640).

In addition, in the second floating wind turbine generator, at least one of the buoyancy regions is damaged by comparing the absolute value of the difference calculated in step S640 and the reference value table (for example, the table in [Table 1]). It may be determined (S650). Damaged here means that the seawater has entered the at least one buoyancy zone and the water is full.

If it is determined in step S650 that at least one buoyancy region is damaged (S660-Y), the second floating type wind power generator may allow one or more load regions to be separated from the load portion (S670). In operation S670, the second floating wind turbine generator may determine that a larger number of buoyancy regions are damaged as the difference calculated in operation S640 is greater, and allow one or more load regions to be separated. This is because when the buoyancy zones and the load zones have a 1: n density ratio of seawater and a load section at the same volume, the volume ratio between one buoyancy zone and one load zone is 1: 1 / n, so the absolute value of the calculated difference is Large means that a large number of buoyancy zones have been damaged, and therefore, several load zones must be removed to maintain the initial balance of the second floating wind turbine.
