Description

{TIDAL POWER GENERATION SYSTEM}

[0001] The present invention relates to a tidal power generation system, and more particularly, to a tidal power generation system, which is installed so as to float on an outer sea side and a sea side sea surface of a seawater for forming a tide in a bay, Thereby continuously generating a flow of seawater through the passage, thereby enabling continuous tidal generation.

Tidal power generation is a power generation system that converts the potential energy into kinetic energy from the water level difference of the tide water (tidal water) and converts it into electric energy.

In other words, as the sea level gradually increases from the low tide to the high tide, the tide moves horizontally toward the coast. At this time, when an aberration is provided on the tidal water inflow direction side, the aberration is rotated by the tide water, and the tidal power generation is a method of generating electric power by driving the generator by the rotational force. As the earth and the moon exist, there is always a uniform tidal horizontal movement, so much research is being done on the tidal generation, which is the next generation energy source.

Such tidal power generation can be classified into a single-flow type and a double-flow type according to the number of lakes, forging knowledge, demodulation knowledge, and direction of use of seawater.

Forging knowledge is the development using a water level difference between seawater and lake by forming one lake, and the demodulation knowledge is the development that uses the difference of water level between two lakes when it is possible to form two lakes normally.

As an example of a typical tidal power plant, the French Langs tidal power plant is capable of both mono-type power generation, amphibious power generation and downstream power generation.

Monolithic power generation is the way in which the development of monkeys is carried out from the outer sea to the lake, or from the lake to the outer sea, and the amphibious power generation is a method of pumping water to the lake using the electricity remaining at night and discharging it by day.

In addition, the recycled power generation is a method of generating electricity in both directions by using the difference in the sea level between the tidal and ebb and the lake. This method starts the development from the outer sea to the lake, and closes the water gate when the water level with the outer sea becomes equal to the lake. When the water level of the lake becomes higher than that of the outer sea, the water gate is opened again and the aberration is reversed to perform the power generation.

The Lance tidal power plant is more complicated than the monolithic aberration due to the need to install an aberration capable of bi-directional power generation. Particularly, the abrupt power generation can be used in a region where even the outer sea is very large, since the power generation is performed from the outer sea to the lake and then the power generation is performed when the water level of the lake is higher than the outer sea. This is a somewhat difficult problem to apply to the same terrain as Korea.

In addition, the reclamation-type power generation is the same as performing the power generation twice using the difference in the sea level between the outer sea and the lake. Therefore, there is a disadvantage in that the number of aberrations must be increased in order to maintain the same amount of generated power as in the case of two-stage power generation.

In addition, the tidal power plant of Shihwa Lake in the west coast of Korea adopts the monolithic power generation system which performs the power generation by using the sea level difference between the sea and the lake, and discharges the water of the lake to the sea without performing the power generation at low tide.

Since the monolithic power generation can only be developed at the time of tide, the utilization rate is low, the required power supply and demand can not be smoothly performed, and the power generation amount can not be arbitrarily adjusted.

Here, since the power generation modules 222 and 222 'and the turbines 224 and 224' are conventionally known, detailed description is omitted.

The turbines 224 and 224 'are installed to be partially submerged in seawater corresponding to the passages 120 of the diaphragm 100 through the open portions of the buoyant members 210 and 210' The turbines 224 and 224 'are rotated by the movement of seawater flowing into or out of the turbine 110.

Accordingly, the turbines 224 and 224 'are rotated according to the flow of the seawater generated by the tide, and the rotation is transmitted to the power generation modules 222 and 222' to generate power.

At the time of tide, the turbine 224 of the floating generator 200 installed on the outer sea side rotates and generates electricity. When the tide is low, the turbine 224 of the floating generator 200 ' ') Is rotated so as to generate electric power, so that it is possible to generate electric power both at the time of tide and at the time of ebbing, thereby improving the power generation efficiency.
