BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertical axis multi-swing open-door turbine for generating power using a flow of fluid, and in particular, to use horizontal movements of fluids such as wind on land or at sea, and sea and sea water flow and river water. The present invention relates to a vertical shaft multi-lid open / close door turbine for generating power using a flow of fluid that operates effectively.

The turbine of the present invention is an open / close door type turbine in which an open / close door is applied as a wing, and is a drag type turbine in which the turbine is rotated by the drag force generated by the wing. In the past, open and close door type turbines similar to the present invention have been proposed, but these turbines had a low power generation rate and were insufficient to be practical. The low power generation rate of these turbines is due to the failure to achieve optimization of the turbine structure.

According to the present invention, structural requirements such as the number of blades, the width of the turbine blades, the angle of the blade surface, the diameter of the turbine, and the like of the turbine can be used to effectively operate the vertical axis open-door turbine, that is, to achieve optimization of the turbine structure. This paper presents the analysis of mechanical factors such as propulsion, rolling resistance, rotational force, rotational speed, and rotational speed of the tip of the wing.

The present invention is to provide a turbine for generating power more effective in using the horizontal motion of the fluid, such as wind or tides occurring in nature, and also to propose a power generator including the appropriate. Since the vertical multi-blade open / close door type turbine of the present invention utilizes horizontal movement of the fluid, the power generation mechanism is different from those of the turbine using the vertical movement of the fluid. In addition, the multi-opening door type turbine of the present invention uses the drag generation deviation of the blades as the rotational force, and thus the power generation mechanism is different from turbines using the lift force of the blades as the rotational force.

Previously, there have been several cases where vertical shaft open-door door turbines similar to the turbine of the present invention have been proposed, but they have not been able to explain the structural requirements necessary for the efficient operation of the turbine because the contents of the invention are focused on the explanation of the principle of operation. It was. Accordingly, the present invention proposes the structural requirements as well as the mechanical requirements of the turbine so that the vertical shaft open-door turbine can be operated efficiently.

That is, in the present invention, the turbine structure is observed by observing the number of blades, the width of the blades, the angle of the blade surface, the turbine diameter, the rotational speed, the linear velocity of the blade tip (ie, TSR), the propulsion force, the rolling resistance, the rotational force and the like with respect to the flow rate. To achieve optimization.

The present invention is a vertical axis multi-role open / close door type for power generation using a flow of fluid capable of effectively mobilizing the kinetic energy of the wind moving on land or at sea, and the horizontal movement of fluid such as sea and river waters in the sea and coast The purpose is to provide a turbine.

Since the turbine of the present invention has a specificity in the structure of the turbine with respect to the existing similar types of turbines, hereinafter the structure of the turbine and the mechanical observation in addition to the configuration of the turbine, the operation process of the turbine present.

In order to achieve the above object, the vertical axis multi-role open / close door type turbine for power generation using a fluid flow according to the present invention,

A rotating shaft installed perpendicular to the center of the structure;

Upper and lower horizontal rotating plates which are respectively installed horizontally at predetermined upper and lower end points of the rotating shaft at horizontal intervals;

A plurality of pairs of vertical members which are vertically lowered in pairs to the outer circumferential side of the horizontal rotating plate between the upper and lower horizontal rotating plates to tightly connect these rotating plates; And

It is configured to include a plurality of opening and closing doors are installed to enable the opening and closing by the flow of fluid suspended in the multi-stage vertical member of the pair.

The rotary shaft of the turbine is vertically supported at a predetermined portion on the upper and lower end sides so as to be rotatably supported by the support. It may also be associated with a gearbox or a generator at one end.

The upper and lower horizontal rotating plate is in the form of a disk centered on the rotating shaft and the binding means is provided so that the vertical members of the pair can be lowered down vertically at regular intervals on the outer circumferential side thereof.

The pair of vertical members are paired at near and far distances from the rotation axis at regular intervals on the outer circumferential side of the rotating plate, and the plane formed by them is deflected by a predetermined angle toward the rotation axis or rearward of the turbine rotation direction. It can be.

The vertical member of the pair has a binding means (hinge ring, latch ring, etc.) at regular intervals in the vertical direction so that the opening and closing doors can be suspended. In particular, the pair of vertical members is made thinner and made of a tougher material so as to generate as little rotational resistance as possible during turbine rotation.

The open / close doors are horizontally bound together in multiple stages on the same side of the pair of vertical members. Opening and closing doors are provided with binding means (hinges, latches, etc.) at an upper end thereof so as to be fastened to the binding means provided on the vertical members. In particular, these opening and closing doors should be made of a light material as much as possible to operate sensitively by the fluid flow.

One or more auxiliary horizontal rotating plates may be further installed between the upper and lower horizontal rotating plates. The installation of the auxiliary horizontal rotating plate is to alleviate the torsional phenomenon of the wing surface generated during turbine rotation.

Hereinafter, with reference to the drawings will be described in more detail the configuration of the turbine according to the present invention.

1 is a perspective view showing the appearance of a vertical axis multi-role open / close door turbine for power generation using a flow of fluid according to the present invention.

As shown, each wing of the turbine 100 is composed of a pair of vertical members 104 and a plurality of small opening and closing doors 105 hanging in a multi-layered manner. The pair of vertical members 104 is installed to be lowered vertically downwardly between the upper horizontal rotating plate 102 and the lower horizontal rotating plate 103 to connect the rotating plates. In addition, the widths of the opening and closing doors 105 suspended from the pair of vertical members 104 are generally smaller than 1/3 of the radius R of the upper and lower horizontal rotating plates 102 and 103. Therefore, a very large cylindrical space portion exists inside the turbine and the rotation shaft 101 exists in the center thereof.

2 is a vertical sectional view schematically showing the configuration of a turbine according to the present invention.

As shown, the upper and lower horizontal rotating plate (102, 103) performs a function of transmitting the drag generated by the wings to the turbine shaft 101. They are made of solid material and of sufficient thickness to support the shape of the turbine from external forces.

3 and 4 is a horizontal cross-sectional view cut in the horizontal direction the middle portion of the turbine according to the present invention.

As illustrated, each of the vertical members 104 and the opening and closing doors 105 have positions opposite to each other about the rotation axis 101, and the wings have a symmetrical structure about the rotation axis 101.

5 is a view showing a state in which the opening and closing door is bound to the vertical member.

As shown, the opening and closing doors 105 are horizontally bound in multiple stages at the same side of the vertical member 104, and are installed to be opened and closed freely upon receiving the fluid flow. A binding means (hinge ring) is provided on each pair of vertical members 104, and a binding means (hinge) is also provided at the upper end of the opening / closing doors 105.

6 is a vertical cross-sectional view showing a state in which the auxiliary horizontal rotating plate 110 is further installed between the upper and lower horizontal rotating plate (102, 103) of the turbine according to the present invention.

(Operation process of the turbine)

Hereinafter, a process of operating the turbine of the present invention when receiving a flow of fluid will be described. However, in order to facilitate the description, only the case where the direction of the door face toward the rotation axis will be described.

As in FIG. 7, a plurality of Y-axis lines are assumed passing through the axis of rotation 101 of the turbine and parallel to the flow direction F of the fluid. These Y axes lie on any plane in the vertical direction (ie, the Y axis plane). The Y-axis surface is rotated in conjunction with the change of the direction of the fluid flow, and is in a position that bisects the wing portion of the turbine to the left / right region.

In the turbine of the present invention, when there is no flow of fluid, the opening and closing doors of the respective blades remain stopped while their surfaces are lowered, but when the flow of fluid is directed toward the turbine, the left region of the Y axis surface The opening and closing doors (c) of the to perform the opening operation, while the opening and closing doors (b) of the right area to maintain the closed state. Accordingly, different magnitudes of drag force are generated on the wings of both sides of the turbine, thereby causing a drag deviation about the rotational shaft 101 to act as a rotational force. As such, when the rotation operation of the turbine starts, the opening / closing doors (c) entering the left region of the Y-axis surface naturally perform the opening operation, while the opening / closing doors (b) entering the right region of the Y-axis surface are naturally closed. Since the operation of the turbine of the present invention is to continue the rotational movement through this continuous opening and closing operation of the opening and closing doors 105 as long as the flow of fluid is maintained.

(Structure of turbine)

The turbine of the present invention is a vertical shaft / omnidirectional turbine whose vertical rotation axis is vertically installed and rotates by receiving fluid flow, and is an open / close door type turbine which performs opening and closing operation when the blade of the turbine receives fluid flow. It is a drag turbine where the turbine is rotated due to the deviation of the drags generated by the vanes.

In particular, the turbine of the present invention has a structural specificity of a multi-wing turbine which forms a large number of blades of the turbine so as to maximize the generation of propulsion force.

In order to overcome the structural drawbacks of existing similar turbines, the turbine of the present invention uses structural factors such as the number of blades, the width of the blades, the angle of the blade surface, and the diameter of the turbine to the hydrodynamic and dynamic principles involved in the turbine rotational movement. It is set accordingly. That is, the turbine of the present invention has a structure that satisfies the following structural requirements.

1) For vertical axis open / close door type turbines, the blades shall be formed on the outer circumferential side of the turbine (ie the edge side). The propulsion of the turbine is effective only when the contact between the fluid flow and the wing surface is generated as far as possible from the axis of rotation.

2) The vertical axis open / close door type turbine should have a form in which a large number of wings are closely arranged. This is because the propulsion force of the turbine is generally generated effectively as the contact area between the wing surface and the fluid is formed to be as wide as possible, that is, to minimize the portion of the fluid flowing out without affecting the wing surface during fluid flow.

3) The vertical axis open / closed door turbine has a cylindrical space inside the turbine when the above two requirements are met. Generally, the larger the size, the more efficient the propulsion of the turbine is.

4) Satisfactory propulsion force can be obtained in the vertical shaft open / close door type turbine in the range of 15 to 40 blades. High thrust force is generated even in the number of wings above, or the excessive force of the rotational resistance is likely to reduce the rotational force rather.

5) Since the vertical axis open / close door type turbine has a large number of blades, there is a possibility that the rolling resistance of the turbine may be greatly generated. Therefore, the member (ie, the wing frame) used to minimize the generation of the rolling resistance must be in the vertical direction. It should be presented and its thickness should be as thin as possible.

6) In the turbine of the present invention, the number of blades n is limited to 15 to 40, and the blade width d has a size within the range of 4R / n to 8R / n depending on the number of blades n. That is, in the turbine of the present invention, the number of blades n of the turbine is set to a certain number in the range of 15 to 40, and the blade width d has an appropriate size in the range of 4R / n to 8R / n.

Therefore, in the turbine of the present invention, the blade number n and the blade width d of the turbine can be given by the following equation.

     15 ≤ n ≤ 40, 4 R / n ≤ d ≤ 8 R / n

Therefore, in the turbine of the present invention, the total sum of widths n * d of each blade can be expressed by the following equation.

     4 R ≤ n * d ≤ 8 R, 15 ≤ n ≤ 40

7) The turbine of the present invention can generate high propulsion force when the angle θ of the wing surface is adjusted to an appropriate size according to the number of blades n and the blade width d. In general, the angle θ of the wing surface (i.e., the rear refraction angle of the wing surface) can be generated when the turbine blade number is smaller and the blade width is relatively small and the deflection is relatively large. The larger the blade width, the higher the propulsion force is to be deflected with a relatively small angle θ of the wing surface. Observations have shown that the vane angle is in the range of 50 ° to 75 ° in the wing number 15 to 20 and the wing width (4 to 5R) / n range, and in the wing number 30 to 35 and the wing width (6 to 7R) / n range. It fits well with vanillary angles between 35 ° and 60 °.

8) The turbine of the present invention shows a large change in power generation rate depending on the rotational speed of the turbine (ie, rpm) and the linear velocity ratio (ie, TSR) of the tip of the turbine blade to the flow rate. Observations have shown that the turbine's rotational speed is preferably less than approximately 30 revolutions per minute, and the blade tip rotational speed of the turbine is half the maximum no-load rotational speed (usually in the range of 25 to 45% of the flow rate). Speed), satisfactory power is generated.

9) The turbine of the present invention should be formed as large as possible, that is, when the rotational speed is as low as possible, higher power can be obtained from the same fluid flow.

(Mechanical observation of turbine rotational motion)

The rotational force of the multi-axis vertical open / close door turbine according to the present invention is generated as a result of the action of two opposing forces, the propulsion of the turbine and the rotational resistance of the turbine.

     Rotational force (power) = propulsion-rotational resistance

As can be seen from the above equation, in order to generate the maximum rotational force of the turbine, the propulsion force should be maximized first, and at the same time, the minimization of the rotational resistance force can be achieved. The turbine of the present invention is formed with as many wings as possible in order to maximize the generation of propulsion force, and has a wing width of an appropriate size corresponding to the wings. On the other hand, in the turbine of the present invention, in order to minimize the occurrence of rotational resistance, the blade member (ie, the wing frame) is taken in the vertical direction, and the thickness of the member is applied as thinly as possible.

8 exemplarily shows a tendency of the magnitude of the propulsion force and the rotational resistance force as the number of blades of the vertical axis open / close door turbine increases.

Curve A is the propulsion graph of the turbine. It is shown that the propulsion force of the turbine is relatively low in the range where the number of blades of the turbine is relatively low, and the propulsion force increases as the number of blades increases, but the propulsion force does not rise any more and remains constant at a certain number of wings. However, a trend such as curve A can be obtained only when the blade width is appropriately sized according to the number of blades of the turbine. The slope of the first half of curve A is considered to have a slope close to the elliptic parabola.

Curve B shows the rotational resistance of the turbine rising sharply when the horizontal member is applied as the base of the blade, and curve C and curve D are the vertical members of the horizontal member when the horizontal member is applied as the base of the blade. This is a graph showing the rising slope with a relatively gentle slope. Also, curve D shows that the thickness of the applied vertical member is thinner than that of curve C, and the rolling resistance increases with a gentler slope. On the other hand, these curves all have a linear upward trend.

As shown, the magnitude of the rotational force of the vertical axis open / closed turbine is given at the point where curve A and curve D intersect any vertical line at blade number n, that is, the interval between a 'and d'. The turbine of the present invention is therefore intended to have a structural requirement in which the above-mentioned spacing segment a'd 'is maximized.

On the other hand, the vertical axis multi-swing open-door door turbine according to the present invention is a process for generating a rotational kinetic energy from the mechanical point of view.

Rotational kinetic energy (power) per unit time = torque (torque) x rotational angular velocity

According to the observation. In the turbine of the present invention, it can be seen that power generation is effectively performed when the rotational linear velocity of the turbine blade tip is operated at a speed in the range of 25 to 45% of the flow rate.

Observation shows that the turbine of the present invention tends to increase the power generation rate when the turbine diameter is increased at a constant wind speed. On the contrary, when the turbine diameter is constant and the flow velocity is increased, the power generation rate tends to decrease. can see. In other words, the rotational speed of the turbine is considered to have a great influence on the power generation rate of the turbine. The turbine of the present invention may have a low power generation rate when the rotation speed is more than 30 revolutions per minute in the field, and the turbine is operated so that the rotation speed becomes much smaller than 30 revolutions per minute. It is preferable.

Observation has shown that the turbine of the present invention can generate approximately 35-50% of the kinetic energy of the fluid flow as the propulsion force, so that the rotational force (i.e. power generation rate) is 30-45% when the rotational resistance is minimized. It can be achieved.
When the number of blades n and the blade width d of the turbine of the present invention are limited to the above-mentioned range, that is, when the power generation rate is limited to 15 ≦ n ≦ 40 and 4R / n ≦ d ≦ 8R / n, the power generation rate is 30. The facts from experiments and observations are presented below to illustrate the effect achieved by ˜45%.
1) Turbine power generation rate (hereinafter referred to as efficiency) is not only structural number of vanes (n), vane width (d) and vane deflection angle (θ) but also the diameter of the turbine, the magnitude of the wind speed, and the blade tip rotation line of the turbine. It is greatly affected by the speed. In other words, high efficiency implementation of the turbine is achieved when the blade deflection angle, the diameter of the turbine, the magnitude of the wind speed, and the blade tip rotational speed of the turbine are in a suitable range, in addition to the numerically defined conditions.
2) The number of blades, blade width and angle of refraction of the turbine are structural elements that are important for high efficiency. However, if the number of blades of the turbine is too small, high efficiency cannot be achieved at the source. This is the most important factor.
3) Observing the change in the efficiency value according to the change in the number of wings shows the following facts. However, the wing number change at this time is when the optimum wing width and wing surface refraction angle are respectively provided.
The maximum efficiency achievable at wing number 8 is up to 20%, provided that the turbine diameter is large enough and the wind speed is in the proper range.
The maximum efficiency achievable at wing number 13 is up to 28%, provided that the turbine diameter is large enough and the wind speed is in the proper range.
The maximum efficiency achievable at wing number 18 is up to 35%, provided that the turbine diameter is large enough and the wind speed is in the proper range.
The maximum efficiency achievable at wing number 23 is up to 40%, provided that the turbine diameter is large enough and the wind speed is in the proper range.
The maximum efficiency achievable at wing number 28 is up to 43%, provided that the turbine diameter is large enough and the wind speed is in the proper range.
The maximum efficiencies that can be achieved in the range of 33–40 wings are up to 45%, provided that the turbine diameter is large enough and the wind speed is in the proper range. The maximum efficiency of the vertical multi-role open / close door drag turbine of the present invention reaches its limit in the range of the number of blades.
4) As can be seen from the above, the turbine of the present invention, unlike the conventional quasi-turbine, exhibits a marked increase in efficiency as the number of wings increases. Compared with the efficiency of existing quasi-turbines, it can be said that an additional efficiency increase of 15 to 25% is achieved. In the turbine of the present invention, the increase in efficiency due to the increase in the number of wings is remarkable when the number of wings is relatively small, and the increase in efficiency due to the increase in the number of wings is insignificant. Therefore, the turbine of the present invention can be said that the efficiency is increased progressively as the number of blades increases.
5) In determining the range of wing widths to match the number of wings, one thing that cannot be overlooked is that the wing width and the angle of refraction are complementary. In other words, the original wing width can be reduced to some extent and the wing surface refraction angle is increased to find the original effect. On the contrary, the original wing width can be increased to some extent, and the wing surface deflection angle can be found.
6) Looking at the effects of changing the wing width within the limited wing width, there is no specific section causing a sudden effect change, and shows a curved change gradually falling after a gentle rise. This curvilinear change can, of course, be obtained by then adjusting the wing refraction angle well. The maximum power is not necessarily obtained in the middle region of the defined wing width range, but it can achieve an effect close to the maximum power.
7) In the case where the number of wings is relatively small, the upper and lower limits of the limited wing width range may be at least 25% efficient. In particular, the upper limit of the number of wings 15, 16, 17 is somewhat excessively limited, but it is also possible to obtain an efficiency of 25%. On the other hand, when the number of wings is relatively large, the upper and lower limits of the wing width range can exhibit an effect of at least 30%. However, the efficiency acquisition at the upper and lower limits is achieved only when the condition that the diameter of the turbine has to be sufficiently large or larger than a certain amount and the condition that the wind speed must be in an appropriate range are satisfied.
8) According to wind power test, 14% of power is obtained at wind speed of 4m / s for turbine diameter of 0.8m and 15 blades, and wind speed of 6.6m for wind turbines of 2.2m and 15 blades. 20% power is obtained at / s, and 30% power is obtained at wind speeds of 4.5m / s for 4.3m turbine diameter and 15 blades. In other words, when the number of blades increases the diameter of the turbine under a constant condition, it can be confirmed that the higher the diameter, the higher the efficiency is generated. In addition, if the power curve of the blade 15 turbine is made from the data, it can be seen that the theoretical power is close to 37%.
9) The turbine of the present invention has an efficiency of 30 to 45 in a typical wind speed environment (ie, a wind speed of 3 to 15 m / s) if the windmill has a diameter of 12 m or more, the number of wings is 30, and the wing width is in the above limited range. % Can be achieved.

Hereinafter, various forms of generating power by including a turbine according to the present invention will be described.

The power generating apparatus including the turbine according to the present invention may be implemented in various forms according to the object to be used, the place where it is installed, and the number of turbines included. That is, it may be implemented in various forms depending on whether the flow of air, using the flow of running water, installed on land, installed in the water, or whether the turbines are collectively included.

Therefore, the present invention will be described representatively three embodiments as follows.

1) Power generating device installed on land and using wind (hereinafter referred to as 'land windmill')

2) Floating power generators using tidal flows in coastal waters, currents in distant oceans or rivers (hereinafter referred to as 'floating aberrations')

3) A power generator in which a number of turbines are included and stacked in layers (hereinafter referred to as 'collective windmills')

(1) onshore windmills

Onshore windmills are installed in certain windy areas such as beaches, islands, mountainous areas, plains, and deserts to generate power from wind power.

9 and 10 are a perspective view and a vertical sectional view of an onshore windmill.

As shown, the onshore windmill includes a turbine 100 of the present invention, which is erected vertically in a horizontal plane so as to utilize the flow of air; A turbine support (112) (114) for rotatably supporting it; A support 120 for stably fixing these turbines 100 and turbine supports 112 and 114; The power chamber 121 converts the power generated by the turbine 100 into electric power or the like.

The turbine supports 112 and 114 support the rotating shaft 101 of the turbine and rotatably include the turbine. These parts need to be provided with means for alleviating the friction of bearings and the like in contact with the rotating shaft.

The stabilizer 120 horizontally holds the turbine 100 and the turbine supports 112 and 114, and is fixedly connected to the turbine supports 112 and 114, and the turbine 100 at a central portion thereof. It has a bearing hole through which the rotating shaft 101 of) passes.

The power chamber 121 is provided in the lower portion of the mounting table 120, includes a portion of the rotating shaft 101 and is provided as a space for accommodating the generator 130 and the like.

(2) floating aberration

Floating aberrations can be powered from tidal power by mooring offshore or underfloor to use tidal streams in coastal waters, ocean currents in distant oceans, or river flows.

11 and 12 are perspective and vertical cross-sectional views of the floating aberrations.

As shown in the figure, the floating aberration is a device generating power by receiving seawater flow (or river water flow) by floating on the water surface with the turbine of the present invention standing vertically.

The floating aberration is the turbine 100 of the present invention, which is erected perpendicular to the fluid flow so as to utilize the flow of the fluid; A turbine support (113) (114) for rotatably supporting the turbine (100); A stabilizer (120) for stably fixing the turbine (100) and the turbine support (113) (114) and having a buoyancy chamber (122) therein; A power chamber 121 provided on an upper portion of the settable 120 to convert power generated by the turbine 100 into electric power; The mooring means 123 is attached to the side surface of the stabilizer 120 to moor the entire device.

In particular, the stabilizer 120 has a bearing hole through which the rotating shaft 101 of the turbine 100 penetrates in the center thereof, and a buoyancy chamber 122 having a sufficient space to float the entire device on the water surface therein. ) Is provided.

In addition, the mooring means 123 is connected to the surrounding fixture so that the floating aberration does not flow as much as possible by running water.

(3) collective windmill

Collective windmills include a plurality of turbines collectively in one facility, in particular two-row arrangement or can be installed in a layered structure.

13 and 14 are perspective and horizontal cross-sectional views of the collective windmill.

As shown, the collective windmill can be formed in a two-row array structure by properly defining the spacing of the turbine and the arrangement of the turbine. Once the turbines in the first row are subjected to fluid flow, the turbines in the second row are arranged to effectively utilize the fluid flow that falls between the turbines in the first row.

When the collective windmill takes a two-row array structure, it is advantageous to increase the height of the facility because it is easier to take structural stability compared to the single-row array windmill or single windmill.

The turbine of the present invention overcomes the low efficiency (i.e. 20% or less) of the conventional similar open / close door drag turbine, and defines the number of blades (n) and the blade width (d) of the turbine as follows. When properly held, power can be effectively (30-45%) derived from the horizontal flow of fluid.
15 ≤ n ≤ 40, 4R / n ≤ d ≤ 8R / n, where R is the turbine radius
The turbine according to the present invention has the effect of maximizing the generation of momentum of drag by limiting the number of blades and the width of the blades as described above, making the contact of the fluid flow and the blade surface to the edge side of the turbine, and to the inside of the turbine It has the effect of minimizing the part of the fluid that flows out without affecting the wing surface among the incoming fluid flows.It has the effect of expanding the contact area between the fluid flow and the wing surface according to the wing surface deflection. As a result, the effect of greatly increasing the flow rate of the front fluid of the turbine can be obtained. That is, the turbine of the present invention can produce a combination of the above effects, as a result can exhibit a high efficiency performance (that is, efficiency 30 ~ 45%) far beyond the low performance exhibited by conventional similar turbines.
On the other hand, the turbine of the present invention, because the wing surface is formed in a flat surface, compared to other turbines having a curved surface, the manufacturing convenience, and also does not require a direct control device, the overall system configuration is simple.
Since the turbine of the present invention tends to have a higher power generation rate as the diameter of the turbine increases, it is reasonable to increase the size of the turbine.
