Description

The power system using the flow rate of the barge-type fluid {THE POWER GENERATING SYSTEM OF BARGE METHOD UTILIZING THE FLUID VELOCITY}

The present invention relates to a power generation system. In particular it relates to power generation systems which utilize the flow rate of a fluid, in particular water. In general, most power generation systems use hydro, thermal and nuclear power, and sometimes wind, tidal or solar power, but they are very small compared to the total generation. The present invention is a power generation system using the flow of fluid uses the flow of fluid formed in the sea or river as a source of power generation. In other words, it is a system for converting kinetic energy of a fluid into electrical energy. In large plants that use heat, such as thermal or nuclear power plants, a large amount of cooling water is used for the safety of major machinery and components. In this case, the cooling water used is mainly pumped up by sea water or river water, and then used as cooling water, and then discharged back to the river or the sea by a natural / forced circulation method. In this case the cooling water used may be used as a source of power generation using a suitable system. There is a hydroelectric power generation system that can be used as a power generation system using cooling water. However, since a hydroelectric power generation system needs a sufficient drop of water and most of the waterproof paths where the cooling water is discharged need to maintain a gentle slope, it is actually necessary to use a hydroelectric power generation system. It becomes an obstacle. Thus, in order to properly use hydropower by utilizing the cooling water of a large plant, power generation that does not require a facility that can change the environment such as a dam without changing the flow path of the discharged spillway to create a large drop. System is required. The present invention relates to a system that can be utilized for power generation in such cases.

The present invention is for use in hydroelectric power generation by utilizing the cooling water of the existing large-scale plant. Unlike the conventional hydroelectric power generation system, it does not require a separate piping work or waterway work, and does not change the flow of the coolant significantly. It is a power generation system. In addition, the present invention is a power generation system using kinetic energy of the fluid due to the movement of the fluid, not using the potential energy of the water, unlike the existing hydroelectric power generation using the drop. In particular, the present invention using kinetic energy of water has the following purpose.

First, the present invention aims at a power generation system for converting kinetic energy of a fluid generated from the motion of a fluid, in particular, kinetic energy of water into electrical energy. As a power generation system using kinetic energy of a fluid, a wind generator is used. However, a wind generator is limited in the installation place, and the efficiency is a problem because the wind with the required speed does not always occur in a place where it is always installed. In addition, there are hydroelectric power systems and tidal power generation systems using water, but such a power generation system uses the potential energy of water and is limited to a place where a necessary drop can be generated. Due to construction, there are problems caused by artificial natural environment, and in the case of tidal power generation system, the amount of power generation is considerably limited. The present invention is a power generation system using kinetic energy due to the movement of water instead of using a drop of water. Unlike hydroelectric or tidal power generation, the restriction on the location conditions is considerably relaxed and the environmental impact is not great.

Secondly, the present invention aims to provide an efficient power generation system compared to other power generation systems. Another power generation system that uses the flow of fluid is the wind power generation system, but since water is much denser than wind, the kinetic energy per unit volume is much greater than that of wind and thus the power generation efficiency is high. In the present invention, propeller-type aberration is used to efficiently use the kinetic energy of water. The propeller-type aberration used in the present invention is a structural change in order to make full use of the kinetic energy of water, and determines the most efficient propeller number by experiment. The propeller manufactured in this way enables the power generation efficiency of the system according to the present invention to be much higher than other power generation systems.

Third, the present invention aims to provide a power generation system in which restrictions on location conditions are relaxed. Existing hydroelectric or tidal power systems can only be installed where they can provide the required drop. However, the power generation system according to the present invention can be installed anywhere where the required flow rate exists. If there is a flow rate such as a river or river or tidal current of the sea, the power generation system according to the present invention can be installed. In addition, it can be installed at the place where the coolant is discharged from the existing plant and operated simultaneously with the thermal power generation system, the hydroelectric power generation system or the nuclear power generation system.

Fourthly, the present invention aims to provide a power generation system with low installation cost of the entire system. The power generation system according to the present invention uses a propeller-type aberration, and the propeller-type aberration is small in size. If it is possible in terms of the location conditions and if a large amount of power generation is required, the required power generation is possible by increasing the number of propeller-type aberrations, and in the case of a small flow rate, the number of aberrations is adjusted accordingly to suit the power generation or location conditions. Can regulate the amount of power generated. This adjustment is also possible by adjusting the propeller size of the propeller type aberration. By using such a small propeller-type aberration, it is possible to reduce the installation cost of the system as a whole by adjusting the number of propeller-type aberrations as necessary.

Fifth, an object of the present invention is to provide a power generation system that can utilize efficient fluid movement. In this design, the guide vane for the flow control, the vertical moving tower and the improved propeller type aberration are used for efficient use of the kinetic energy. The guide vane for flow control adjusts the amount of power generated according to the flow rate to enable a certain amount of power generation. The vertically movable tower is a device for placing the aberration in the proper position for the efficiency of the aberration arranged in the lower part. Propeller-type aberration can be rotated 180 degrees according to the change of flow velocity, and it is a device equipped with a multi-function control system, such as using a proper deformation of the gear to transmit the propeller rotation efficiently. By using such a device, the power generation system according to the present invention can increase the efficiency of power generation.

Sixth, an object of the present invention is to provide a system that can be developed using the barge method. In other words, it is possible to increase the efficiency of power generation by placing propeller-type aberrations at the fastest speeds by installing the necessary power generation system by using barges floating at a certain position by using anchors in the sea and allowing barges to move up and down. . Of course, the power generation system according to the present invention does not necessarily have to use a barge. However, when the power generation system according to the present invention is installed in the sea it is most advantageous to install using a barge.

Hereinafter, the power generation system according to the present invention having the above purpose will be described in detail.

Hereinafter, a power generation system according to the present invention will be described with reference to the drawings. It will be apparent to those skilled in the art that the presented drawings illustrate one embodiment of another power generation system in the present invention, and the present invention is not limited thereto.

1 shows an overall schematic diagram of a power generation system according to the present invention installed on a barge.

Arrows shown in FIG. 1 indicate the flow velocity direction.

The barge 1 is fixed in position by a jet anchor 10. The advantage of using the barge 1 is that the depth at which the aberration 15 is submerged in water can always be kept constant even if the water level changes. The selection of the barge 1 position is determined by preliminary examination of the location conditions, and the fixing method is not necessarily limited to the anchor, and the position can also be moved. Up and down mobile tower 11 is fixed to the propeller-type aberration 15 is installed at the bottom, the electric cable for supplying power generated from the aberration is installed inside the tower (11). The tower 11 according to the present invention has a structure capable of moving up and down so that the propeller-type aberration 15 installed at the bottom thereof can be fixed at an appropriate position. Since the flow rate varies depending on the depth, it is necessary to position the propeller-type aberration 15 at the position where the flow rate is maximum to produce the maximum power. In addition, by selecting a position with a suitable flow rate to control the amount of power generated according to the speed, it is possible to prevent the power generation more than necessary, and also to obtain the stability of the entire wiring system or device. Of course, the barge 1 itself can be moved up and down by buoyancy, but the tower 11 makes the selection of the position simpler and easier and ensures the accuracy of the positioning. The power distribution room 12 is a place where the cable installed in the tower 11 is an end point, and the electric energy generated in the propeller-type aberration 15 is finally integrated on the barge and the overall control of the power generation system is performed. The integrated power may be transmitted to the required place through the wiring, but the wiring installation requires a considerable cost when the power generation system of the present invention is installed in the sea such as the barge (1). Therefore, it is also possible to use the electricity generated once, convert it to another storage means, and then move it to where it is needed. One such example is the use of generated power to produce hydrogen fuel and then move it to where it is needed. Safety net 13 is generally installed for the safety of the barge (1) and catamaran type pontoon (14) is also installed due to the nature of the barge. Propeller-type aberration 15 installed at the bottom of the tower 11 is manufactured in a form capable of rotating 180 degrees according to the direction of the flow rate. Generally, algae in the oceans are not uniform in direction and can change with night and day or with the seasons. In this case, it is necessary to change the direction of the aberration 15 to obtain the maximum flow rate. In general, the barge 1 itself has a fixed position and direction, and is capable of adjusting its upper and lower positions by buoyancy. Since the efficiency of the power generation system according to the present invention is determined by the size and direction of the flow velocity, the direction of the propeller-type aberration 15 according to the direction of the flow velocity is mounted at the bottom of the tower 11 so as to rotate the aberration 15. As described above, the selection of the proper flow rate according to the depth is made by the vertical movement of the tower 11 itself. In the above way, the power generation system according to the present invention can make the most of the kinetic energy of the fluid. The guide vane 16 for adjusting the flow rate is installed at the front of the aberration 15 and fixed using a separate fixing means or the tower 11. In addition, it is also possible to manufacture integrally combined with the propeller-type aberration 15. The vane 16 forms a wider front end and a narrower rear end so as to increase the efficiency of the power generation system by using a difference in speed according to flow rate. The flow rate flowing into the vane 16 can be adjusted by manufacturing a variable type to adjust the size of the front end portion of the vane 16. Such adjustment of the flow rate is also necessary for the generated power to have a constant value. A device for varying the vane 16 front end is fabricated using generally known methods.

Figure 2 shows one embodiment of the propeller-type aberration that characterizes the subject innovation.

The aberration used in the present invention is not equipped with a pitch control system that can adjust the propeller angle commonly found in aberrations such as a general wind power generation system or Kaplan. Since the flow rate is close to 100 tons per second of a few meters per second, if the pitch control system is installed in the aberration 15 according to the present invention, the strength of the joint is weak, so that it is difficult to withstand the impact caused by water and is easily waterproofed. You may not lose. Therefore, in the case of tidal power generation where the fluctuation of the flow rate is very large or when operating alone without being synchronized with the system, a frequency controller (AC-DC conversion and DC-AC conversion system) capable of controlling the frequency of the output voltage should be used.

Hereinafter, the components of the propeller-type aberration shown in FIG. 2 will be described in detail.

The hub 21 rotates together with the propeller as a device for protecting the propeller shear. The vane 16 described in FIG. 1 is provided in front of the hub 21. Propellers or propellers are shown in the form having three in FIG. 2, but may have an appropriate number as necessary, such as two or four. It is advantageous that the shape of the propeller 22 be such that it has the most efficient propeller shape recognized in hydrodynamics. Rotation of the propellers 22 is transmitted to a low speed shaft 240 installed at the rear of the hub along the central axis of rotation. Rotation of the low speed shaft 240 is transmitted back to the gear 241. The gear 241 used in the present invention may be used in a general form, but it is advantageous to be manufactured in a special form. That is, the role of the gear 241 used in the present invention converts the low speed rotation of the propeller 22 into the high speed rotation and does not change the direction of power transmission. Therefore, a gear that only serves to change the rotation ratio is necessary, so that the part connected to the low speed shaft 240 is not necessarily used, but the part connected to the low speed shaft 240 forms the outside so that a large number of gear teeth are formed inward. And the portion connected to the high-speed shaft 242 has a smaller circumference than the gear formed in the portion connected to the low-speed shaft 240 is formed so that a small number of gear teeth can be formed to make the two parts integral. Such gears are called planetary gears. Power whose rotation ratio is converted in the gear 241 is transmitted to the high speed shaft 242 to rotate the turbine 243 to generate power. The control of the devices inside the housing 24 including the low speed shaft 240, the gear 241, the high speed shaft 242, and the turbine 243 is achieved by the multifunction control system 244. That is, the control device 244 serves to transfer the power transmitted to electrical energy appropriately and transmit the power to the power distribution chamber 12 shown in FIG. 1 through the cable 25. In addition, the control device 244 may adjust the flow rate flowing into the flow rate guide vane 16 shown in FIG. The yaw drive 246 installed at the coupling portion of the aberration 15 and the tower 11 enables the rotation of the aberration 15 and also serves to mitigate the impact due to the inflow of the flow rate. The rear end of the housing 24 is a nacelle 245 to facilitate the movement of the fluid.

Figure 3 shows various embodiments of the propeller form of the propeller used in the aberration 15 of the present invention. The dynamics associated with propellers are basically similar to those used for wind power generation. Three formulas are used:

High-speed operation coefficient: λ = U / V ₀ ... (One)

U = ω × R... (2)

Rotation momentum: c _M = M / (ρ / 2 × V ₀ ² × R × A)... (3)

Output coefficient: c _P = P / (ρ / 2 × V ₀ ³ × A)... (4)

In the above, U: linear velocity of the front part of the propeller, V ₀ : flow velocity without resistance, ω: propeller rotation speed, R: propeller radius, M: inertia coefficient, ρ: fluid density, A: propeller area , P: output.

Figure 3 (a) is a form having a thin area consisting of two propellers (b) shows a form having a thick area and (c) shows a form having four propellers. As a result of evaluation experiments for (a), (b) and (c), the maximum output was obtained when λ was 5.5, 4.0 and 3.0, respectively. At this time, the maximum output coefficient was 0.45. The propellers used in the experiments were 6m in diameter and 6m / s in flow rate. Under these conditions, each propeller had a maximum output at 105 rpm, 70 rpm and 55 rpm, respectively, and the value was about 3 MW. This is in agreement with Equation (4), and when the flow rate was reduced to 3m / s, the output power rapidly decreased to about 360kW. Therefore, the selection of the propeller shape in the above manner should be determined experimentally to allow the maximum power generation in consideration of the moving speed of the fluid in the position where the barge 1 is installed and the flow rate that can be introduced.

Cavitation of the propeller was evaluated together in the above experiment.

As can be seen from the above experimental results, (a) form is most likely to generate cavitation because the propeller of form (a) must rotate at the fastest speed to obtain the same output under the same conditions. In general, the analysis of the cavitation is possible only through detailed simulation, but in the case of (a) of FIG. 3, it can be analyzed using the analysis result of the centrifugal pump.

In extreme situations where cavitation occurs, the total energy is given by

Total energy = (PV _a ) / ρ + Δe... (5)

It is given in the above as a ^{_{Δe = λ V × V 2/}} 2 + λ w × W 2/2 from the

λ _V and λ _w represent coefficients given by 1.2 and 0.2, respectively. Assuming a flow rate of 6 m / s, cavitation occurs when the propeller pressure drops below 1.2 bar. When the propeller diameter was 6m and the flow rate was 6m / s, the pressure was maintained at 1.2 bar or more under the maximum output condition. Therefore, there was little possibility of cavitation. However, if the rotational speed is temporarily increased, cavitation may occur in front of the propeller.

As a result of the above experiment, it can be seen that in the case of the three types of propellers shown in FIG. However, if there is a power failure due to an accident in the nearby power system or if the excitation power is cut off due to a failure of its own electrical facility, the propeller operates under no-load and can be overspeed at a considerable speed. Cavitation is very likely. Therefore, it is advantageous for safety to install a system that prevents prolonged overspeed rotation of the propellers by bringing the propellers to the surface as soon as possible in the event of a power failure by using a subsystem equipped with an uninterruptible power supply (UPS). Do.

4 illustrates an embodiment of the arrangement of the aberration 16 according to the present invention. 4 (a) shows the parallel arrangement with respect to the moving direction of the fluid, and FIG. 4 (b) shows the arrangement in series. The arrangement of the form (A) is to be installed in a wide area where the flow rate is slow and relatively fluid flows. (B) can be used in a region where the flow rate is narrow and the flow rate is high. The number of the aberrations 15 arranged will be determined by the flow rate, the width through which the fluid flows, and the amount of power required. In the case of the arrangement as shown in (b), the power generated by each aberration 15 may be different. In the case of the arrangement (b), the arrangement such as (b) is generally not preferable because the change of the flow velocity may be severe depending on the situation. In fact, the experimental results show that even when the diameter of the propeller is 6m and the flow rate is 6m / s, there is a considerable drop in the flow rate at about 70m. Various simulation experiments show that the spacing between propellers must maintain at least 10% of the propeller radius for parallel connections such as (b). In practice it would be advantageous to maintain a spacing of about 20% to about 50% of the propeller radius in consideration of mechanical safety.

Example

An embodiment of the installation and generation amount of the power generation system according to the present invention applied to the cooling water waterproof path of a domestic thermal power plant will be described below.

1. Data of Cooling Water Ditch in Domestic Thermal Power Plants

(1) Flow rate: 116. 82 tons per second

(2) Flow rate: 2.6-3.89 m / s

(3) waterproof furnace length: total extension 150m

(4) waterproof path width: 30m

(5) Depth: about 1.54 meters

Assuming that the flow of cooling water is a natural flow, the equations (1)-(4) given in the description above apply. Assuming that the slope of the spillway is about 10 degrees on average, the flow rate of the fluid flowing into the propeller is about 10m / s, and the depth is about 0.4m at the given flow rate for a given flow rate system is installed.

2. Installation method of aberration according to the present invention

(1) Installation plan without changing the structure

If the existing waterway is used without changing the structure of the waterway at all, the diameter of the propeller is limited to 1.0-1.1m in consideration of the depth of 1.54m. In consideration of mechanical safety, the diameter was set to about 1.0 m.

If the distance between the aberration and the aberration is maintained at 20-50%, and 20-25 aberrations can be installed at the width of the 30m watertight path, ignoring the influence of the aberrations, the amount of power generated per aberration is obtained as follows.

P = c _p x p / 2 x V ₀ x A... (6)

The power generated by one propeller is 3.1kW when the flow rate is 2.6m / s and 10.5kW when the flow rate is 3.9m / s. Thus, installing 20 aberrations will yield 62.0-210.0kW of power.

(2) Improvement of performance through change of structure

As shown in Eq. (4), the output power is proportional to the diameter of the propeller and at the same time the third power of the flow velocity. Therefore, in the case of a structure change, in case of a structure change that increases the depth of water, it is advantageous to change the structure in the direction of increasing the flow rate since the flow rate may be slowed down and the overall power generation output may be remarkably decreased. Do. If all installations that block the flow of coolant in the final stage of the spillway are removed, the flow rate will be about 10 m / s and depth of 0.4 m. In this case, the power generation system according to the present invention may use a propeller having a diameter of about 0.3 m and install about 80 aberrations in a 30 m wide waterproof path. The power generated per aberration is about 15.9kW, and when all 80 aberrations are installed, about 1.27MW is generated. However, since it is not possible to install gears and generators in about 0.3 meters, the gears and generators must be converted to compression, and a helical gear or the like is expected to cause about 10-20% of mechanical loss.

3. concrete detail device

(1) propeller

Since the water depth is about 1.54m, the diameter of the propeller is set to about 1m in consideration of the fluctuation range. The propeller uses a propeller shown in FIG. 4 (b).

(2) generator

Induction generators are most advantageous in terms of grid linkage, ie frequency control, and no voltage control. In general, the efficiency of an induction generator is about 85%, which is inferior to that of 88-90% of a synchronous generator. However, in the case of a synchronous generator, some conditions must be provided in order to feed into the system, and in the case of the system according to the present invention, a frequency control device such as an overspeed governor is quite difficult.

Induction generators are presently known as winding type and squirrel cage, and the winding type is slightly more efficient than squirrel cage type. Commonly used induction generators are poles of 4 poles (1800 rmp), 6 poles (1200 rmp), 8 poles (900 rmp), and 10 poles (720 rmp). In general, the larger the number of poles, the larger the generator size. It is advantageous to increase the mechanical burden and efficiency by reducing the acceleration ratio by using the generator with the lowest possible rotational speed, but the generator with the rated rotation which is too low due to the structure that the propeller, the acceleration gear, and the generator should be integrally manufactured It is difficult. In case of using a 6m diameter propeller, there is no difficulty in manufacturing, but in case of 1m diameter, a separate plan must be prepared to produce a one-piece. One alternative is to use a 24-pole synchronous generator. 24 pole synchronous generators exist only in the form of stators forming magnetic fields composed of permanent magnets. Only 10 years ago, multi pole synchronous generators below 10 poles are extremely inefficient and bulky. Due to the very advanced characteristics of the magnet, even in the case of a 24-pole synchronous generator, the efficiency is high and the size is also very small. In case of using synchronous generator, however, proper start / stop control should be carried out to properly feed the system according to the characteristics of synchronous generator. In particular, voltage should be controlled because there is no separate exciter.

When using an induction generator rated at 72 rpm, the generator specifications are as follows.

Type: 3-phase winding AC induction generator

Capacity: 15kW

Power factor: 0.74 (at full load)

Insulation class: F class

Voltage: 380 V

Rated rotation speed: 720rmp (10 poles)

Connection: Y Connection

Excitation method: Self excitation method using on-site power distribution system (380V)

Standard: IEC 34-1 standard

(3) gears

In the case of the propeller shown in (b) of FIG. 4, the highest output occurs when the motor rotates at about 70 rpm when considering the speed-torque characteristic. Therefore, this speed should be defined as the rated speed of the propeller and the gear with the proper acceleration ratio should be selected according to the ratio between the rated speed of the generator and the rated speed of the propeller.

When using a 10 pole induction generator of 720 rmp, a gear of 11x speed can be selected, in which case the propeller rotates to about 65.5 rmp. In practical experiments, the efficiency showed little change between 65-75 rmp.

(4) the number of propellers

Since the width of the cooling water repellent path is 30m, a propeller with a diameter of 1m can be installed with a total of 20 propellers if the spacing between propellers is set to about 0.5m.

(5) housing

There is a need for a housing that can safely secure and waterproof aberration systems that include propellers, planetary gears, and generators.

(6) fixing frame

Since the waterway is closed, the wall itself serves as a support for the propeller and power generation system. An epidemiological review of the propellers subjected to flow pressures of 2-3m per second should be preceded. However, it is to be provided with the function to lift all three propellers at the same time for repair.

(7) protection and control devices and breakers

The hydroelectric power plant according to the present invention does not need to be specifically controlled except at start / stop and failure. An operating panel for the protection / control device for general start / stop, protection and alarm is also installed in the water substation in the plant. The breaker consists of a low voltage 600V MCCB and a magnet switch and is installed in the aberration generator operating panel placed in the substation in the sewage treatment plant.

The scale of protection and control equipment depends on whether the generated power is connected to a 220V distribution line or to a 22.9kV distribution line. 6 and 7 illustrate circuit diagrams for installing a protection relay and a breaker in the case of being connected to a 220V distribution line and a 22.9kV distribution line, respectively.

Power generation system according to the present invention having the configuration as described in detail above has the following effects by using a propeller-type hydraulic power aberration using the speed of the fluid different from the conventional concept of hydraulic power aberration using the free fall.

Unlike conventional aberrations, it does not require a drop, but only a sufficient flow rate and depth, which can reduce the cost of civil works, and it is possible to save a large amount of energy such as a thermal power plant, a nuclear power plant, a chemical plant or a steel mill. Cooling water that is thrown away from the cooling water can be used for hydroelectric power generation. It can also be used as an alternative energy source that can produce large-scale energy that is comparable to thermal or nuclear power plants, using high-speed rivers or ocean currents. In addition, the amount of energy supplied is so great that there is no fear of exhaustion, and having a small facility, it is possible not only to distribute energy but also to clean energy, so there is no fear of ocean or air pollution. In addition, it is possible to install a power system by modifying an existing device without using special conditions or special materials, and unlike the case of thermal power generation, there is no effect of changing the price of energy provided.
