Description

TECHNICAL FIELD The present invention relates to an apparatus and method for analyzing the feasibility of a wind turbine using dust,

The present invention relates to an apparatus and method for analyzing the feasibility of a wind farm using a dust amount, and more particularly, to an apparatus and method for analyzing feasibility of a wind farm using a dust amount, And an apparatus and a method for judging the validity of the wind farm according to the calculated total dust amount.

Wind energy, one of clean energy, can be said to be one of the major energy sources in the future. In tune with this, wind design technology has progressed considerably and is continuing to evolve with modern technology development.

Selection of large wind turbine complex sites with adequate wind power generators, use of large capacity machines, higher tower heights, greater area of rotating blades, better aerodynamics and structural design, faster computer-based machining techniques, increased power factor Can produce more power. In windy areas, wind power is already more economical than traditional fossil fuel-based technologies. With improved technology and excellent economics, wind power is expected to account for a significant portion of the global energy market by 2020.

Since the wind turbine is more wind-driven and the larger the wind turbine can produce more wind energy, the power generation of the wind turbine depends on the wind strength and the size of the wind turbine. This makes the site more difficult. The area surrounding the wind farm is located in a remote location to minimize the damage of plants and animals. Also, as the height increases, the wind blows harder, so the generator in the higher place is larger than the generator in the lower place and the generation amount is also higher. Therefore, it is appropriate for wind power to be located in remote areas such as sea, desert, mountain, beach, island where wind speed is high and wind is high.

The offshore wind power designed for this is less problem of landscaping damage, and it can be said that the problem of land acquisition is few. On the other hand, on-land wind power is difficult to select a suitable geographical location due to constraints of residence, commercial area, and land acceptance problems. On the other hand, offshore wind power can install large-capacity wind power generators, while onshore wind power has a limited turbine size that can be installed due to road width, road curvature, and restrictions on transportation equipment. Therefore, the offshore wind turbine can transport tens of MW of wind turbines according to the capacity and size of the ship, which can create a large-capacity, large-scale wind farm.

Recently, geographic information system (GIS) is being used to analyze wind power facilities and geographical conditions. (1) the depth of the sea (to select the type of offshore structure according to the water depth and submarine geologic conditions when building offshore wind farms); (2) the distance from Ian (the distance between the submarine power lines (3) grid linkage (grid linkage with substation is the main factor that affects the cost of offshore wind farm construction together with offshore structure), (4) maritime national park , Seagoing ports, harbors, military training areas, submarine cables and pipes (separated into inaccessible areas in consideration of appropriate buffer areas).

The physical quantities measured by the ocean sensor measure the radiance in the visible to near-infrared region under the condition that there is no interference by the atmospheric pollution, and the water-leaving radiance (Lw) To provide biological or optical information in the ocean. Generally, the amount of radiation in the wavelength range measured by the ocean sensor is relatively small at sea level, while the effect of atmospheric aerosols is relatively large. Airborne particulate matter, or atmospheric aerosols, are known to be responsible for radiative forcing effects and climate change due to the ability to absorb and scatter solar radiation.

Two major optical properties (light scattering and absorption) of these atmospheric aerosols act as disturbing factors in remote sensing of terrestrial observations (land and ocean) and are of major interest in remote sensing of the Earth's atmosphere It is. Therefore, it is essential to understand the role of aerosols in the atmosphere and their role in the radiative transfer process.

Thus, selection of wind farm sites plays an important role in predicting wind energy efficiency in the early stage of site selection. To utilize the basic data for site selection so far, it was limited to the extent to observe and forecast the wind direction and wind speed of the region, and the utilization of data was very limited. However, considering the above location selection, material conditions due to the movement of the atmosphere used for wind power generation are not included.

Although the Korean peninsula has been influenced by yellow dust in the spring and summer from China, there has been no study of the effect of wind energy from yellow dust. Especially, since the Korean peninsula is affected by various aerosols (dusts or pollutants) originating from the continent, it is necessary to evaluate the contribution of atmospheric aerosols in the ocean observation and to use the technology to remove the influence of the atmospheric aerosol Do.

The present invention is derived from research carried out by the Ministry of Education, Science and Technology, the Korea Research Foundation, and the Mokpo University Industry-Academy Collaboration Foundation as part of the LINC promotion program.
