Description

{Ship having solar power generation function and posture adjustment method for sail power generation unit}

The present invention relates to a method for adjusting the attitude of a ship equipped with a solar power generation function and a sail power generation unit.

In order to improve fuel efficiency by obtaining thrust from wind power on large ships such as cargo ships, various methods are being studied to install airfoils that can act as sails on the cargo holds of cargo ships. When the airfoil is placed in a position where it receives the maximum wind force, lift is generated by receiving the wind, and this lift has the advantage of generating maximum thrust.

In addition, as the number of large ships sailing the seas increases, environmental problems caused by exhaust gases emitted from ships are also becoming a major issue. Typically, a main engine and a power generation engine are used as internal combustion engines in ships. The main engine is used to generate the ship's propulsion, and the power generation engine is used to produce power used by power demand sources inside the ship.

In the case of large ships, the capacity of the power generation engines is considerable, so the emission of exhaust gases, which are the main cause of environmental pollution, is considerable not only while sailing but also while staying near ports or anchorages.

To solve these problems, various technologies are being developed to equip ships with solar power generation facilities and produce electricity using eco-friendly techniques.

However, airfoil installation technology to obtain propulsion using wind power or eco-friendly power generation technology using solar energy are being studied separately as independent new technology fields, so there is a lack of consideration for integrated research, and airfoil and solar panel are each independently researched. Therefore, there is a problem in that a considerable installation area is required to be installed on a ship, which reduces the economic efficiency of operation.

The matters described in the technical background section of this invention are for understanding the background of the invention, and cannot be assumed to be prior art already known to those skilled in the art in the field to which this technology belongs.

However, this is not intended to limit the present invention to specific embodiments, and should be understood to include all changes, equivalents, and substitutes included in the spirit and technical scope of the present invention.

Figure 1 is a block diagram schematically showing the power system of a cargo ship according to an embodiment of the present invention, and Figures 2 and 3 illustrate the shape and posture of the power generation unit provided on the cargo ship according to an embodiment of the present invention. It is a drawing, and FIG. 4 is a drawing for explaining a power operation technique of the power system of a cargo ship according to an embodiment of the present invention.

In this specification, for convenience of explanation, the description will focus on the case where a plurality of sail power generation units 120 are arranged in an n x m array on the deck of the ship 210. However, it is natural that one or more sail power generation units 120 may be provided in various quantities and arrangements in various locations such as decks, living quarters, etc. In addition, it is natural that the type of ship 210 equipped with the sail power generation unit 120 may also vary, such as a cargo ship.

Referring to FIG. 1, the power system of the ship 210 may include a control unit 100, a generator engine unit 110, a sail power generation unit 120, and a battery unit 130.

The control unit 100 may include a basic information collection unit 101, an attitude adjustment unit 103, a power source operation unit 105, and a storage unit 107.

The basic information collection unit 101 collects basic information such as environmental information, power generation information, and fuel consumption information at each point in time when the ship 210 operates.

The basic information collected by the basic information collection unit 101 may be stored in the storage unit 107, and the collected basic information may be used to control the attitude of the sail power generation unit 120, as will be described later.

Environmental information collected by the basic information collection unit 101 includes, for example, weather information, information on the altitude and azimuth of the sun, wind speed and direction information applied to the ship 210, and information on the wind speed and direction generated by the ship 210. It may be one or more of vibration information, etc. The basic information collection unit 101 may include one or more sensor devices to collect environmental information, and marine weather information may be collected from, for example, one or more weather information providing organizations.

The power generation information collected by the basic information collection unit 101 may be information about the amount of solar power generated in the current posture of the sail power generation unit 120 equipped with a power generation panel, for example, the sail power generation unit 120 This may be information measured by a solar power generation meter provided in .

The fuel consumption information collected by the basic information collection unit 101 is information about the amount of fuel used for the operation of the ship 210, for example, the wind direction and speed applied to the ship 210, and the This information may change depending on navigation speed, etc. In addition, the basic information collection unit 101 may further collect information about the amount of fuel used to operate the generator engine to supply power to power demand sources within the ship 210 as fuel consumption information. Fuel consumption information may be, for example, information measured by a measuring device provided in a fuel supply device provided in the ship 210.

The attitude adjustment unit 103 adjusts the attitude of the sail power generation unit 120 to correspond to the basic information currently collected by the basic information collection unit 101.

As illustrated in FIG. 2, the sail power generation unit 120 may be installed in one or more pairs on each of the port and starboard sides of the ship 210. Of course, the quantity and arrangement form of the sail power generation units 120 installed may vary, such as the sail power generation unit 120 being arranged along a continuous center line from the bow to the stern direction of the ship 210. there is.

Each sail power generation unit 120 may be configured to include a sail body 222 and a drive unit 224 for rotating the sail body 222 or adjusting the inclination angle of the sail body 222. . Here, the sail body 222 may be made of a rigid body material whose shape and size do not change due to the wind, and may be formed, for example, in the shape of an airfoil, wind sail, etc. You can.

Additionally, the sail body 222 may be made of a power generation panel composed of solar power cells that perform solar power generation, or the power generation panel may be mounted on the surface of the sail body 222. Power generated by the power generation panel provided in the sail power generation unit 120 may be stored in the battery unit 130.

The driving unit 224 of the sail power generation unit 120 rotates the sail body 222 or adjusts the inclination angle under the control of the attitude adjustment unit 103 so that the sail body 222 is adjusted to various postures in three-dimensional space. can do. For example, as illustrated in FIG. 2, one or more sail bodies 222 may be adjusted to a posture facing the bow or side of the vessel 210 ((a), (b), (d) of FIG. 2 ), one or more sail bodies 222 may be adjusted to a tilted or lying position (see (c) and (d) of Figures 2).

For example, when a tailwind (tailwind) blows, the attitude adjustment unit 103 controls the operation of the drive unit 224 so that the sail body 222 is in an attitude that generates drag by hitting the wind (i.e., an attitude that increases propulsion force). It may be possible (see Figure 3 (a)).

In addition, if there is no need to adjust the sailing speed of the ship 210 using a tailwind or if a headwind blows, the attitude adjustment unit 103 lays the sail body 222 (see (c) in FIG. 2) or tilts it 90 degrees. It can also be rotated horizontally (i.e., axially rotated) (see (b) in Figure 3) to create an attitude that does not resist the wind.

In addition, the attitude adjustment unit 103 may horizontally rotate the sail body 222 to form a diagonal direction with respect to the wind direction so that the moving direction of the ship 210 can be adjusted using the wind (Figure 3(c), (see (d)). In Figures 3 (c) and (d), a case where each sail body 222 is axially rotated in the same posture is illustrated, but each sail body 222 is adjusted according to the angle at which the moving direction of the ship 210 is adjusted. ) It is natural that the posture (i.e., rotation angle and tilt angle) may be adjusted differently.

Of course, as will be described later, the attitude adjustment unit 103 further considers not only the wind speed and wind direction but also the elevation angle and azimuth of the sun, and determines at what angle the sail body 222 should be rotated and at what angle the driving unit will be tilted. The operation of (224) can also be controlled. Here, the attitude adjustment of the sail body 222 based on the wind speed and wind direction may have a major influence on the navigation speed and direction of the ship 210, and the attitude adjustment of the sail body 222 based on the elevation angle and azimuth of the sun. may have a major influence on the power generation amount of the power panel.

The attitude adjustment unit 103 applies the basic information currently collected by the basic information collection unit 101 to the previously machine-learned attitude determination model to adjust the optimal attitude angle of the sail body 222 of each of the sail power generation units 120. can be decided. Here, the posture adjustment angle may be a rotation angle indicating by which angle the sail body 222 should be rotated in three-dimensional space.

The attitude determination model uses the existing navigation and basic information collected up to the previous point to determine the change in operational fuel consumption of the ship 210 and the change in solar radiation incident area according to the change in the size of wind resistance for each adjustable attitude of the sail body 222. Learn changes in power production and adjust the current attitude of the sail body 222 based on currently collected basic information (e.g., wind direction, wind speed, solar elevation and azimuth, fuel consumption rate, power generation, etc.) It can be configured to determine the optimal angle.

The attitude determination model uses not only the basic information collected during the existing navigation of the corresponding ship 210 and stored in the storage unit 107, but also the basic information accumulated and collected by the basic information collection unit 101 up to the immediately preceding point in time to determine the vessel ( 210) can be set to learn in real time while operating.

The attitude decision model may be set to perform learning for each pre-specified decision mode, such as a fuel consumption minimization mode, a power production maximization mode, a fuel consumption and power production optimization mode, etc. Through this, the attitude determination model can determine the optimal attitude adjustment angle of the sail body 222 based on the decision mode selected by the manager of the ship 210. Here, the fuel consumption and power production optimization mode may be, for example, a mode in which the ship is operated with fuel consumption below the fuel consumption threshold and also determines the attitude adjustment angle indicating the amount of power generated above the minimum power production value.

Pose decision models include, for example, Fully Convolutional Neural Network, Convolutional Neural Network, Recurrent Neural Network, Restricted Boltzmann Machine, and Deep Belief Neural Network. neural network) can be created as one or more deep learning-based models. Of course, it can be implemented with machine learning techniques other than deep learning techniques, or it can be created as a hybrid model that combines deep learning techniques and machine learning techniques.

In addition, methods for learning the pose determination model can also vary, including supervised learning, unsupervised learning, and reinforcement learning.

When the attitude adjustment unit 103 adjusts the attitude of the sail bodies 222 included in each of the sail power generation units 120, it is not limited to adjusting the attitude of the sail bodies 222 only to shapes that are the same or symmetrical to each other. , the posture of each sail body 222 may be adjusted individually based on currently collected basic information (e.g., wind direction and wind speed, solar elevation angle and azimuth, etc.) (see (d) in FIG. 2 ).

Referring again to FIG. 2, the power source operation unit 105 operates the generator engine unit 110 for a power demand source (e.g., cooling load, engine room fan load, HVAC load, lighting load, etc.) provided in the ship 210. ) and control the operation of the generator engine unit 110 and the battery unit 130 so that power can be supplied from one or more of the battery unit 130. The generator engine unit 110 may include a plurality of generator engines that consume fuel to generate power.

The power source operation unit 105 may be set to control the operation of the generator engine unit 110 and the battery unit 130 so that they are driven according to pre-specified optimal power operation standards.

The optimal power operation standard can be set based on the characteristics of the generator engine, where the fuel consumption rate varies depending on the size of the load factor. For example, generator engines are generally optimized at a 90% load rate to have the lowest fuel consumption rate (g/kW) per generated power, and as the load decreases, fuel efficiency worsens and the fuel consumption rate gradually increases.

Therefore, as shown in FIG. 4, the optimal power operation standard is to ensure that the generator engine is additionally started whenever the load increases to reach the efficiency operation unit value at which the generator engine can be operated with optimal efficiency, but when the operation is started, Additional power required so that the generator engine can continue to operate at an optimal fuel consumption rate corresponding to the efficiency operation unit value may be set so that the power stored in the battery unit 130 is supplied to the power demand source.

That is, the power source operation unit 105 operates the generator engine according to pre-specified optimal power operation standards if the load has not yet increased to the efficiency operation unit value, for example, a 90% load rate, at which the generator engine can be operated with optimal efficiency. The operation of the battery unit 130 is controlled so that the power stored in the battery unit 130 is supplied to the power demand source without starting operation.

Thereafter, when the load further increases and reaches the efficiency operation unit value, the power source operating unit 105 starts operation of the first generator engine to handle the load corresponding to the efficiency operation unit value. Thereafter, even if the load increases additionally, in order for the first generator engine to still handle only the load amount of the efficiency operation unit value, the additional power required until the next efficiency operation unit value is reached is the power stored in the battery unit 130. Controls the supply of power to demand sources.

Here, to determine to what level the load has increased and whether the increased load rate satisfies the efficiency operation unit value, the power source operating unit 105 uses, for example, the information measured by the power quantity measuring device, the discharge of the battery unit 130, etc. It can be recognized by referring to the current value, etc.

For example, in the conventional structure in which only generator engines were provided, while one generator engine is driven (100g/kW fuel consumption rate) to handle a load rate of 90%, which is the efficiency operation unit value, if the load rate increases by 10%, One generator engine was additionally driven, and each of the two generator engines was controlled to handle a load rate of 50%. In this case, fuel efficiency is rather reduced, and each generator engine operates at a fuel consumption rate of 130 g/kW even though each generator engine handles a 50% load factor. Therefore, as the two generator engines were operated at a fuel consumption rate of 260 g/kW, there was a problem of worsening fuel efficiency.

In contrast, in the power system according to this embodiment, when one generator engine is driven (100 g/kW fuel consumption rate) to handle a load rate of 90%, which is the efficiency operation unit value, if the load rate increases by 10%, the increased 10% The required power according to the % load ratio is supplied by the power stored in the battery unit 130, so that the generator engine can still be driven at an optimal fuel consumption rate.

As described above, the ship 210 according to this embodiment forms the sail body 222, which is provided to reduce fuel efficiency, with a power generation panel or mounts the power generation panel on the sail body 222, thereby reducing the cargo loading space. It has the characteristics of reducing fuel consumption and producing eco-friendly power without sacrificing energy.

In addition, the posture of the sail body 222 provided in the sail power generation unit 120 can be adjusted in various ways based on the collected environmental information, so that maximum power generation efficiency can be achieved while appropriately using wind resistance. there is.

In addition, the amount of charged power is adjusted according to the power load rate, and through this, the generator engine can be operated to achieve maximum performance, thereby minimizing fuel consumption and optimal energy use.

Figure 5 is a flowchart showing a method of controlling the attitude of a sail power generation unit provided on a cargo ship according to an embodiment of the present invention.

Referring to FIG. 5, in step 510, a posture determination model is machine-learned for each preset decision mode using basic information stored in the storage unit 107.

The storage unit 107 may store the existing voyage of the vessel 210 and basic information collected up to the previous point, and decision modes preset to be machine learned include, for example, fuel consumption minimization mode, power production maximization mode, This may be a fuel consumption and power production optimization mode, etc.

Here, the fuel consumption minimization mode is an attitude adjustment angle of the sail body 222 that minimizes the amount of fuel required to propel the ship 210 by utilizing the wind applied to the ship 210 from the perspective of fuel consumption regardless of power production. It may be a decision mode.

The power production maximization mode determines the attitude adjustment angle of the sail body 222 at which power production by the sail power generation unit 120 is maximized at the current point in time, regardless of the amount of fuel required to propel the ship 210. It could be a mode.

The fuel consumption and power production optimization mode considers both fuel consumption and power production. For example, the ship is operated with fuel consumption below the fuel consumption threshold, and the sail body 222 indicates the power generation amount above the minimum power production value. It may be a mode that determines the posture adjustment angle.

The attitude determination model uses the basic information stored in the storage unit 107 (e.g., information on wind direction, wind speed, solar altitude and azimuth, fuel consumption rate, power generation, etc. collected at each point in time) of the sail body 222. Changes in operational fuel consumption of the vessel 210 according to changes in the size of wind resistance for each adjustable attitude and changes in power production according to changes in the solar radiation incident area are preset to machine learn for each preset decision mode, and are based on the currently collected basic information. Based on this, it may be configured to determine the optimal posture adjustment angle for the sail body 222 at the current point in time.

In addition, the attitude determination model uses not only the basic information collected during the existing voyage of the ship 210 and stored in the storage unit 107, but also the basic information accumulated by the basic information collection unit 101 up to the immediately preceding point. The ship 210 may be set to perform real-time machine learning while it is in operation.

In step 520, when the basic information at the current time is collected by the basic information collection unit 101, the posture adjustment unit 103 uses the posture adjustment model learned to date to determine the currently collected basic information and the decision selected by the manager. The optimal attitude adjustment angle of the sail body 222 of each of the sail power generation units 120 according to the mode is determined.

The basic information collected at the current time is stored in the storage unit 107, and the posture determination model is machine-learned in real time again with further reference to the currently collected basic information (see ① in FIG. 5).

In step 530, the attitude adjustment unit 103 adjusts the attitude of the sail body 222 included in each of the sail power generation units 120 to correspond to the determined optimal attitude adjustment angle, and adjusts the attitude of the sail body 222 included in each of the sail power generation units 120 according to the basic information collected again later. Proceed back to step 520 to determine the optimal posture adjustment angle.

Here, determination of the optimal posture adjustment angle and posture adjustment of the sail body 222 may be performed whenever basic information is collected in real time, but may also be preset to be performed every predetermined period (e.g., 30 minutes, etc.) .

Figure 6 is a flowchart showing a power operation method of the power system of a cargo ship according to an embodiment of the present invention.

Referring to FIG. 6, in step 610, the power source operation unit 105 provided in the power system of the ship 210 operates the generator engine unit 110 and the battery unit 130 according to predetermined optimal power operation standards. For control, it is determined whether the remaining load satisfies a predetermined efficiency operation unit value.

Here, the optimal power operation standard may be set based on the characteristics of the generator engine, where the fuel consumption rate varies depending on the size of the load factor, for example. In other words, the optimal power operation standard is that when the load required by the power demand increases and reaches the efficiency operation unit value at which the generator engine can be operated with optimal efficiency, the generator engine is newly started to continuously maintain the load equal to the efficiency operation unit value. , and the remaining load that falls below the efficiency operation unit value may be set to be covered by the power stored in the battery unit 130.

If the load increases to exceed the efficiency operation unit value and the generator engine is newly started, if the load decreases again below the efficiency operation unit value, the generator engine may be controlled to end operation. In this case, the power charged in the battery unit 130 will be supplied to the power demand source.

If the remaining load does not satisfy the efficiency operation unit value as a result of the determination in step 610, in step 620, the power source operating unit 105 determines that the power stored in the battery unit 130 is transferred to the power demand source according to the remaining load. The operation of the battery unit 130 is controlled so that it is supplied to.

However, if the remaining load satisfies the efficiency operation unit value as a result of the determination in step 610, in step 620, according to the optimal power operation standard, the power source operating unit 105 causes the generator engine to handle the load equal to the efficiency operation unit value. For this purpose, the operation of the generator engine unit 110 is controlled so that the generator engine is additionally driven to produce power.
