Description

The compound tidal generation plant by 3 or 5 steps between double or triple basins}

The present invention relates to demodulated tidal power generation in three to five stages, and more particularly, by applying a water bag aberration or wing folding aberration, or a spring turbine with high energy conversion efficiency even in a low drop, inlet and drainage It is a complex demodulation tidal power plant that generates power at the gate, maximizes the power generation by absorbing all the velocity energy of the offshore by tidal power generation, and meets the power demand by adjusting the power generation of the main power plant and pumping power plant and improves the disadvantages of tidal power generation. .

The water level of the open sea is rising and falling at an average of 6 hours and 25 minutes with high and low tide, but there are times when the high tide and low tide levels differ by more than 1m depending on the manpower depending on the location of the sun and moon. In some cases, the difference in tides may narrow within 1.3-1.5m. Anheung Bay, where the highest tidal water level is close to 7m, has an average tidal difference of 4.2m in April, but most of the time it keeps more than 5m except for a few times, and at least a few times more than 5m during two high tide. And form a gap of more than 3m.

The demodulated tidal power is constructed in the first reservoir and the wider and lower reservoir in the geologically suitable waters, and the water stored in the first reservoir at high tide is stored in the second reservoir and stored at low tide. As it is discharged to the open sea, it is generated by using the drop formed between the two reservoirs only within the limits of the car as shown in FIG. 1, and it is essential to obtain and drain water. You can make money.

However, it is not easy to control the fall, so it is necessary to use a wing-folding aberration, a water bag aberration, or a spring-wing turbine with high conversion efficiency as a power converter in low fall, and an additional hydrological gate can be additionally obtained in the power plant.

The winged aberration is kept in a folded state until the wing attached to the drum hinges on the water inlet and loads water at the inlet and rotates to the drain by gravity and folds out to return water to the inlet, and the waterbag aberration is rotated on the drum. The water bag is attached between the wings attached inclined slightly in the opposite direction to the water pressure. When the water pressure is applied, the fluid is pushed out and the water is filled in the contracted space and the water is rotated by the drain. To rotate the inlet in the closed state, so that both types of aberrations do not escape the wing until the aberration house absorbs the energy when it is loaded and rotated, allowing the wing to absorb energy, until the wing returns to the inlet. Water pressure at the inlet to maintain the folded state or the expansion state of the water bag It is a vertical aberration that reduces the resistance and increases the energy absorption rate by blocking, and converts potential energy into rotational energy even in water, and the amount of passing water is directly proportional to the rotational speed so that the drop can be adjusted by itself.

The spring blade turbine uses the last rotary blade as a spring to narrow the gap between the blades so that negative pressure is generated under the blades, and by adjusting the opening angle by gravity and spring elasticity, it accelerates the flow rate of water flowing through the open gap to increase the energy absorption rate. will be.

Power generation water for 12.8 hours is received for 4-6 hours and then drained for 4-6 hours. When the main power station is operated without interruption, the water level change of the first reservoir and the second reservoir is maintained as shown in FIG. The amount of power generation varies considerably by time zone, especially when the acquisition point is near, the drop in the main power plant is the narrowest, so the combined difference between the minimum and maximum power generation is huge because the combined power generation and drainage generation are huge. Most of the time, unless you have surplus power.

However, if the power generation of the main power plant is adjusted in the average power generation range of the three power plants, the ups and downs of the instant power generation are greatly alleviated, and in particular, since the fall of the main power plant can be controlled, the total power generation is further increased, and the main power plant can be pumped by aberration. I can afford to.

In this case, from the end of acquisition to the start of drainage, and from the end of the drainage to the start of supply, the power generation of the main power plant covers 100% of the average power generation, as shown in the graph of FIG. As it is widened, the target quantity can be developed, but the closer the acquisition time is, the narrower the drop is, so even if all the main power plants are operated, it is difficult to meet the target.

In any case, in order to maximize the total power generation, the first reservoir should be almost empty when the point of acquisition is reached, so the power generation capacity of the main power plant should be large enough to discharge the reservoir reservoir within five hours.

As described above, when the operation rate of the main power plant is controlled, as shown in the graph shown in FIG. 10, the level of the first reservoir is stagnated during the drainage generation, and when the incoming power generation is stagnated, the level of the second reservoir is stagnant, resulting in more drop of the main plant. As it is wide open, the amount of power generation is much increased, and the water for generation of the first reservoir can be relaxed.

Inland power generation increases the rate of increase in the offshore water level for a while, but the amount of power generation increases for a while from the beginning of the acquisition. Originally, the main function of the power plant is to fill the first reservoir up to the high water level, but when the size of the power generation is sufficient, the drop in the power generation of the main power plant and the rise of the offshore water rises more than 1.5m, even if the incoming power generation is delayed by one hour. Power generation increases.

In the case of drainage generation, the larger the width of the drop, the more the drainage increases, and the low tide promotes drainage, and the lower the second reservoir level, the lower the amount of water decreases drastically. As the rate of descent reaches the effective drop quickly, there is little need to run the main power plant for some time because the amount of power generated by drainage and tidal current is higher than the average generation.

Therefore, by replacing electric power demand with drainage power generation, the fall of the main power plant can be expanded by almost half of the difference between tidal and tidal tides.In the middle and second half of the drainage, the power of water saved in the first reservoir is expanded by using the widened drop. It can also be used to replenish drainage water, which greatly improves and reduces energy utilization.

During low power generation, the flow of water to the low tide goes to the sea and there is little congestion that obstructs drainage. It can be further developed by an underwater algae generator.

In the 15-day cycle, saree and a few repetitions of saree are the most available and the second reservoir can be emptied to maintain a fairly high drop, but at some times tidal tea is reduced by almost one third, which significantly reduces power generation. However, if the power generation to pass back to Saree after a bit of low water at the time of Saree, the main power plant can always secure the maximum drop as shown in Figure 2, but no matter how large the fall, if the amount of power generation is small, power generation will inevitably decrease. In the case of low power generation, inflow and drainage are completed within one to two hours, so the inflow and outflow generation loses economic feasibility.

Therefore, in order to maximize the amount of generated power and drainage, the first and second reservoirs must be completely empty at every low tide. Since the amount of generated power and the amount of drained power will never be less than the amount of power generated by the main power plant, the main power plant can be used to compensate for the ups and downs of the power generation, and the remaining power generation can still be stored as a pumping and generating water to improve the ups and downs of the power generation.

In particular, pumping power not only compensates for a small drop in power generation, but also recovers freefalls by delaying the development of pumping power when water supply and drainage are started, or when the main plant's downfall is narrow or when there is insufficient water supply in the first reservoir. It can be used effectively.

Therefore, the present invention uses the water level difference between the open sea and the first reservoir to generate the second reservoir with water obtained at high tide and discharges from the second reservoir to the open sea at low tide, and low drop even in the inlet and drainage gates. Power generation system with high conversion efficiency, and maximizes the power generation by absorbing the flow rate energy of final discharged water into tidal power generation. The main power plant can improve the ups and downs in power generation range of inflow and drainage power plants and tidal power plants. It aims to improve the ups and downs of power generation by adding positive power generation to the three-stage demodulated tidal power generation system that meets the demand of electric power by adjusting the amount of power generation.

In order to achieve the above object, the water supply aberration or wing folding aberration is installed in the water supply door and the auxiliary waterway is installed on the top and bottom of the power converter so that it can be additionally obtained, the drainage door is drained by the wing folding water or propeller generator Power generation, and install an auxiliary waterway on the top of the power converter, to maximize the storage area of the second reservoir as much as possible dredging the bottom to increase the amount of storage.

The main power plant will be constructed on a scale capable of draining the reservoir of the first reservoir for 4 to 6 hours, and will be equipped with spring-wing turbines or winged aberrations and sluices.

To prevent vortices of the final discharged water and to maintain the flow velocity to a long distance, submersible beams are installed on both sides of the drainage, and propeller tide generators are zigzag between them.

When there is abundant water available at the time of saree or when the electricity produced at night becomes surplus power, water is pumped by connecting the aberration power to the water pump through the power connection device, and the main power plant is connected to the main power plant structure. It is stored in the third reservoir dedicated to pumping power generation, which is constructed near the first reservoir, the open sea, the land, and the like to generate the first or second reservoir to meet the power demand.

It is possible to reduce the construction cost of the separate pumping plant by opening and closing the water gate of the inlet and the inlet of some main power plants through the inlet and the main power plant structure. If the inflow channel is not wide enough to form a very fast flow rate, this may result in a considerably narrower drop.

Maximize the amount of power generation and the amount of water obtained by controlling the opening and closing times of the gates and auxiliary gates of the power plants, and adjusting the power generation and the pumping power generation of the main power plant according to the amount of drainage and tidal flow, Develop a storage medium for demodulation tidal power plant operation management program to maximize the total power generation and meet the power demand by adjusting the power generation of the main power plant and the power generation of the pumped-up power plant according to the average power generation range or demand power. do.

The total amount of generation can be further maximized by using the demodulated tidal power generation system that is generated only in the main power plant, by utilizing the amount of water intake, drainage, and flow velocity energy of the external sea as additional power, and controlling the fall by connecting and adjusting the generation times of all power plants. In addition, the main power plant can generate 24 hours of uninterrupted power by adjusting the operation rate so that the incoming generation, drainage generation, and tidal current generation within 16 to 18 hours meet the demand of electricity within the average generation. Pumping power generation can improve almost completely the ups and downs of saree.

The first reservoir may shorten the exposure time of some tidal flats exposed at every low tide, but only tidal flats are maintained for fish farming and can be used as wind farms or solar farms. Since the tidal flats are completely exposed and can be used as reclaimed land, the reclamation and tidal power generation projects can be combined, and the deterioration of water quality due to long-term stagnation of domestic demand can be improved by the circulation of seawater by tidal power generation.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

As shown in FIG. 3, the high place is divided into a first reservoir 113 and the low place is a second reservoir 113a to build a sewage 131, and the first reservoir 113 also has an inlet power plant (37). 37a), the auxiliary waterway 40, and the second reservoir 113a, are constructed with a drainage power plant 38a, which also serves as a drainage gate 38, and an auxiliary waterway 40 for emergency, with the main power plant ( 109 is located.

4 is a cross-sectional view of an inlet power plant 37a provided with a water bag aberration 1 or a wing folding aberration and an auxiliary water channel 40. If the water supply is regulated, the flow rate can be developed. If the water supply is insufficient, the free fall may increase as the high water gets closer. The additional water channel 40 is placed in between to obtain additional water.

Even though the tidal current generator 119 may be installed in front of the inlet gate 37 as shown in FIG. 4, it may cause a congestion in front of the gate so that it may interfere with power generation and acquisition. Let it fall

When draining, the power plant 38a can be constructed with sufficient power so that drainage is not hindered by power generation, and even when the power generation is stopped due to a narrow drop, the wing-folding aberration 5 or the propeller 118 as shown in FIG. 27) and the auxiliary water channel 40 is installed at the top of the aberration in preparation for the flood.

The backflow prevention gate 104 is installed in the water gate and the drain 25 which can control the water inlet 23 and the auxiliary waterway in the inlet power plant 37a and the drain power plant 38a. The amount of power generation can be controlled by opening and closing the backflow prevention door with power, but when it is necessary to empty the power converter section for large repairs, water gates are installed on both sides, and one side is automatically opened and closed by water pressure, and the other side is operated by a machine.

When tidal current is generated using effluent water, eddy currents may be generated due to collisions with stagnant seawater, so the flow rate may be slow. However, even when the water level is increased, the underwater beams 117 are installed on both sides of the drain hole 25 as shown in FIG. ) Is installed zigzag.

The main power plant uses a wing folding aberration 5 having high conversion efficiency as shown in FIG. 6 when the amount of water stored in the second reservoir is low, and when it is desired to reduce the size of the power plant or to obtain a large amount of energy by passing water, as shown in FIG. The turbine (2) is installed, and the water gate (35) is installed at the inlet so as to operate in multiple stages according to electric power demand to adjust the amount of power generation.

When the water flows into the first reservoir 113, the closer to the high water level of the offshore sea 22, the slower the flow rate, and thus the inflow generation alone cannot fill the high water level. Open water gate 35 to obtain additional water, and from this time until the start of drainage power generation in the second reservoir 113a, the power generation of the main power plant 109 increases according to the power demand. Since there is a significant drop, only a few generators can fully meet the target generation.

When the drainage power generation 38a starts, the second reservoir 113a has a large water submerged area, and the external sea 22 has a low water level so that the effective drop is formed early, so that the generation amount of the drainage power plant 38a and the underwater algae generator 119 When the combined amount of power generation is larger than the target generation amount, when the power generation of the main power plant 109 is stopped, the water level of the second reservoir decreases quickly from the middle to the middle of the drainage, and the drop of the main power plant 109 becomes wider.

As the second reservoir 113a approaches the lowest water level 138, the amount of drainage generation decreases drastically, and thus, the main power plant 109 is responsible for power demand until the incoming power generation 37a is restarted. When there is a lot of water for power generation, all the aberrations are operated according to the low water quantity, some are generating power, some are pumping the pumping water generators, and the first reservoir is emptied until the water starts. In the case of positive power generation, the demand for electricity is supplemented.

When the operation rate of the main power plant 109 is relatively low due to the increase in the amount of generated power and the amount of drainage generated, the reservoir level, which is a parabolic reservoir as shown in the graph of FIG. 10, reaches the second reservoir 113a during the incoming power generation, and the first reservoir during 113) is transformed into the stagnation water level 120, so that the free fall widens more than half the level of tidal flats, so the amount of power generated by the main power plant 109 increases even with the same passing water.

The advantage of demodulated tidal power generation is that it can be developed without interruption for 24 hours, but when it is a little and when switching from saree to a little, one out of two times a day has a narrowing gap of more than 1m, so the ups and downs of power generation cannot be avoided. Even if you save the remaining water for daytime use at night, it cannot be used once after a period of 6 hours and 25 minutes, and the amount of power generated is reduced.

Therefore, when surplus power is generated or power generation water is left, the water pump is installed in the main power plant as shown in FIG. 8 and pumped directly with aberration power, and stored in the third reservoir near the water reservoir connected to the top of the power plant. Or by pumping power to the second reservoir 113a, it is possible to meet the demand for electricity between saree and a little, as well as when the water for generation of the first reservoir is insufficient.

9 is connected to the inlet channel 23 to the inlet channel 122 of the pumping channel 101 of the main power plant 109 connected to the third reservoir of FIG. The main power plant 109 can be used as a pumping power plant by modifying the water gate 35a and opening the water gate 35 of the water inlet so as to generate the pumped water for the third reservoir 113b.

When the water level of the third reservoir 113b is lower than the water level due to the pumping power generation, it is possible to save the pumped energy by directly obtaining the water from the external sea 22 or the first reservoir through the access gate.

By directly pumping the power of the power converter and using the power plant structure as a waterway, the construction cost of the pumping plant is saved, and the pumping efficiency increases more than 2.5 times compared to when generating power by surplus power. The effect would be to omit it.
