The present invention relates to the formation and operation of a mixed demodulation tidal tidal power plant, which combines a large and small aberration chamber with a single flow arrangement and a creative downflow regeneration method. The water is separated from the coastal Site George, which has a low amount of inflow of river water into the Georgeland, and the deep sea and the offshore site of the River, where there is no inflow of river water. On the day, the coastal site George develops an algae single-flow development according to the utility of George, and the Offshore Site George creates, erupts and double flows the offshore site. It is a tidal power generation method that increases aberrations and maximizes power production.

In the existing method of forming and developing the method, the method of forging land, the method of creating up-and-down connected demodulation, the method of creating separate demodulation, etc. were examined. The creative development method, the creation, and the fall-back flow development method have been adopted, and it has been customary to place aberrations directly in each George. The ideal form of tidal power generation is the form of total inflow and total amount of drainage, which produces maximum power generation and minimizes changes in marine ecosystems. The difference in the total amount of available water available at the time of city and creative development is so great that it does not produce adequate capacity aberrations and is far from being full or multiplied.

The tidal power generation method needs to maintain the proper head head of the power generation when the inflow or discharge flows through the aberration, but the total amount of available water during the fall and the creative development is largely different due to the proper head head of the power generation and the state of the wide and narrow bottom. For this reason, George must be separated and formed according to its utility. For reference, the total amount of available water during the fall development and the creative development is formulated as follows.

H ₀ : Maximum tide difference (water head at low tide to low tide at low tide)

H ₀₁ : Available head during creation and development (water head from low tide to usable water level at low tide)

H ₀₂ : Available chicken head at the time of algal development

H ₁ : depth of george

H ₂ : Developmental head

A ₁ : Average value of upper area of George

A ₂ : George's lower area average

Q ₁ : Total amount of available water during creative development

Q ₂ : When expressing the total amount of available water during power generation

H ₀₁ = (H ₁ -H ₂ ) or (H ₀ -H ₂ )

H ₀₂ = H ₁ or (H ₀ -H ₂ ) whichever is less.

In the deep water, the difference between (H ₀₁ ) and (H ₀₂ ) is the same, but in the low depth, the difference between (H ₀₁ ) and (H ₀₂ ) is (H ₂ ).

Q ₁ = A ₁ H ₀₁

Q ₂ = A ₂ H ₀₂

It is a formula for the total amount of available water, and the low depth of the coastal George is a very small value including the part where (H ₀₁ ) is less than zero. Since the value of (A ₁ ) is also small, the amount of available water (Q ₁ ) during creation and development is very small, and river water flowing into George is negatively affected by the value of Q ₁ , so it cannot play an appropriate role as George during creation and development. Compared ebb formula developed in the (H ₀₂₎ the value (H ₀₁₎ increases by more than (H ₂₎ values (A ₂₎ value of Fig. (A ₁₎ to increase significantly compared with the value, and the stream water is introduced into George (Q ₂₎ values Plus, it can play an appropriate role as an ebb and flow george.

On the other hand, the deep waters of the offshore Site George have little difference in area between the upper and lower George, and the values of (H ₀₁ ) and (H ₀₂ ) are similar. Therefore, it is appropriate for the offshore site george to generate (currently, fall down) bilateral power generation. At this time, it is important to prevent the inflow of river water into George during creative development.

In the same way as before, when George is formed and developed into a double-flow type, the generation of power is included by including the coastal George, which has little role in creation. When the offshore is full at the end of creation and development, the head difference between George and the offshore water is the value of the appropriate head of development (H ₂ ). Since the surface area is included in the coastal area, the land area is so large that it is impossible to inflow the total water, and consequently, the coastal site George, which is not very helpful in the creative development, is included in the creative development. Power supply can be satisfactory at the time of fall power generation due to the lack of timing It is impossible to do. In this case, there is a situation where George's situation does not increase the power production compared to the short-circuit single-phase power generation.

As described above, according to George's circumstances, the fall-out single-phase power generation is adopted. In this case, the abandoned deep-sea offshore site's creative power generation production is abandoned, resulting in large economic losses, less daily operation time of the aberration, and continuous development. It will also take less time. In addition, in the conventional method of forming George, the required amount of aberrations were installed for each George without any separate aberration chamber.However, the operating time per unit of aberration is limited to during fall or double flow generation. Resulted in installing.

The present invention is divided into two parts, the shore and the offshore site, according to their utility, in order to make up for the shortcomings of the conventional method of making George. Produces dual-flow power generation and installs a plurality of aberration chambers and pump facilities in connection with George to extend the duration of power generation and power by allowing the aberration and pump facilities to be used in each George in the most rational way. It carries out technical tasks to increase production, and even in the case of a special flow of rivers or river waters into the George, such as during the flooding or the rainy season, open the flood gates installed between the Georges and change each of the Georges into an algae single-flow power generation mode. Respond flexibly to a given situation, such as suppressing damage George may be the composition and operating methods in the offering.

The present invention, which achieves the object as described above and supplements the conventional drawbacks, is divided into two by the coast site site and the offshore site as a method of forming the George, each of which is connected to the offshore, aberration chamber and the pump facility, Determine the dividing line between the coastal Site George and the Offshore Site George (referring to the head of the head of the development of the headwater and statistical data of the headwaters due to the difference between tidal waves and the inflow of river water in the contour of George). In order to develop into a single stream of fall, in the offshore Site George, we choose a way of creation and a stream of double stream. In forming a plurality of aberrations, the aberration chamber is one small and one large. It is better to make a decision by referring to the area ratio, but it is better to do it differently. It is possible to make a flexible aberration plan, which can be used all in one George or in turn, and install necessary water gates between George and Aberration Room, between George and Aberration Room, between George and Aberration Room, and operate according to the situation. .

Hereinafter will be described in conjunction with the accompanying drawings the actual example of the present invention.

Figure 1 is a plan schematic view of the tidal power plant George and the facility formed a plurality of aberration chamber according to the present invention

Fig. 2 shows a side cross-sectional schematic diagram of coastal Site George and Offshore Site George to explain the utility of George.

The total amount of available water with the available head (H ₀₁ ) during the creative development of coastal site George 11 in Fig. 2 is very small, and the inflow water plays a negative role in the Q ₁ value, so the coastal site George develops in an algae stream. is the available head (H ₀₂₎ at the time of power available can the total amount (Q ₁₎ having an available water head (H ₀₁₎ at the time of creating the development of offshore Site George 12 and see that, by non-called best option ebb that Since it is about 90% of the total amount of available water (Q ₂ ) and there is no inflow of river water, it is clear that the creation and fall of bipolar power generation is the best option in the offshore Site George.

River or river water flowing into the tide is positively added to the total available water during the development, but negatively affected by the total available water during the creative development. Therefore, the influent flowing from the river or river is to be introduced into the coastal site George (11) determined by the algae single flow power generation method to increase the power productivity. However, if the upstream streams need to be increased by heavy rains or rainy seasons, coastal Sites alone may be difficult to handle. In this case, (3), 312, 313 of Figure (1) is opened to open the river water also to the offshore Site George 12 to switch to the single power generation mode to prevent the flood damage of the George upper stream.

When George's area ratio is about 4: 6 and the number of aberration arrangements in each of the aberration chambers is 1: 3, as shown in Fig. 1, the aberration operation method is as follows.

Assuming that the surface of the open sea and the open sea Site George (12) and the offshore Site George (11) are high tide at 0 o'clock in a cycle where the development head is set to 2m to 3m and the difference between tidal waves is 5m. in

Close all floodgates installed in George and the aberration chamber, shut off the discharge of water through the aberration, and wait until the sea surface of the open sea (13) becomes (high tide-1m).

When the sea surface of the open sea is (high tide-1m)

The water chambers 341, 342, 361, 362 are opened, and all of them pass through the aberrations 41, 42, 43, and 44, and start to produce fresh water with the water of George on the coast.

At this time, the head of power generation is not rated at 1m, so it is difficult to draw the output electricity into the power system. Therefore, the water is sent to the pump room 50 and the water of the coastal site George 11 through the inlet 51 and the outlet 52. To be pumped to the offshore Site George (12). In addition to pumping, the water level of the offshore Site George 12 becomes (high tide + pumping amount / surface area), so that the offshore Site George (12) and the offshore before the sea surface level of the offshore (13) becomes (high tide -2 m) The head difference between (13) becomes 2m.

When the head difference between the outer sea side George 12 and the outer sea 13 is 2 m, the water gates 341 and 342 are closed, and the water gates 351 and 352 are opened to send water from the offshore Site George 12 to the aberration chamber. (41, 42, 43, 44) are all used to develop.

At this time, the power generation head is 2m, so the generated electricity is introduced into the power system and the transmission is stopped by the pump station. It continues to develop until the sea surface of the open sea reaches (low water level + 1m), and when the water level of coastal site George (11) exceeds the high tide, the water gates (311, 312) are briefly opened for a short time. Water from the coastal Site George 11 is sent to the offshore Site George.

At the time when the sea level is (low tide + 1m), the water gates (361, 362) are closed and the water gates (341,342) are opened. George's water continues to generate 2m water head using aberrations 42, 43, and 44. At this time, electric power can also be drawn into the power system.

When the sea level is (low tide + 0.3 m)

The water gates 321, 322, and 323 are all open. Opening of the water gates 321, 322, 323 causes the water level of the offshore Site George 12 and the aberration chamber 22 to begin to dive, resulting in a decrease in the power output of the aberrations 42, 43, 44, but the aberration 41 Power generation capacity is increased by 4m, so power generated up to a certain point can be introduced into the power system.

At the point when the electricity production is so low that it is difficult to draw into the power system, the water gates 351 and 352 are closed, and the water gates 361 and 362 are opened, so that the water in the coastal site 11 is discharged using only the aberrations 41 and 42. Power generation is 4m, and the generated power can also be introduced into the power system.

When the sea surface level of the open sea 13 is at the low tide, the surface water level of the offshore site George 12 is also close to the low tide level, and when the water level of the offshore sea 13 rises, the offshore 13 and the offshore sea level 12 There are times when the water level will be the same.

When the water level of the open sea 13 is equal to the water level of the offshore site George 12, the water gates 321, 322 and 323 are closed and all the water wheels 43, 44 are operated. The draw power that is difficult to draw is sent to the pumping station 50 to pump water from the offshore site George 12 to the open sea 13 using the inlet 52 and the outlet 53. The open sea and the water level (low water level + 1m) ), The offshore site George's water level is (low water level-1m) and the coastal site George's water level is (low water level + 3m).

At the time when the water level of the offshore sea 13 and the offshore site water level difference reaches 2m, the pumping stops, the water gates 341 and 342 are closed, the water gates 351 and 352 are opened, and the water of the offshore water is introduced into the offshore Site George 12. And begin creative development with aberrations (41, 42, 43, 44). Open sluice gate 331 to allow water from shore George to escape to the open sea and re-enter.

By the high tide of the open sea where the creative development is over, the power generation is almost the same, so that the power can also be introduced into the power system.

Prepare for the development of a new cycle at 12 o'clock

As described above, when the power head appropriate for power generation is set to (2 to 3 m) and the head difference between tidal waves is 5 m

The daily running time is about 11 hours * 2 = 22 hours, and the time to introduce electricity produced in the power system into the power system is about 10 hours * 2 = 20 hours.

As described above, the present invention has the effect of increasing the efficiency of land use by maximizing the amount of electric power generated and produced in George of the same area by separating and forming George according to the utility of George, and adopting each generation method suitable for each George. In addition, by forming a plurality of aberration chambers in connection with George and installing necessary pumping facilities and water gates, it maximizes the daily operating time per unit of aberration to improve the productivity of aberrations and to easily draw the generated electricity into the power system. In addition, it is possible to maximize the power production and reduce the flood damage in the upper stream by allowing the hydrological and other floodgates formed between the states to be manipulated according to the situation and making rational aberration plans.
