Description

Site Analysis System and Method for Wind Power

The present invention relates to a wind farm site analysis system and method.

There is a growing interest in renewable energy around the world. Among the renewable energy sources, wind power generation is emerging as the core of renewable energy with low production cost and high technical maturity. In line with the trend of the world's use of renewable energy, the Korean government has announced plans to increase the rate of renewable energy supply from 2.49% in 2008 to 11% in 2030. It is expected to be about 40 times larger than in 2008.

As wind power is being promoted at the national level, wind power generators will be expanded. However, there is no manual for the location selection of wind power plants in Korea, and there is a lack of research on location selection.

In recent years, people have raised questions about the efficiency of wind power. This is because the actual amount of power produced is small compared to the capacity of the wind turbine. In fact, in many regions except Gangwon-do, the utilization rate of wind power generators is low. This reflects that Korean wind power generators are not being installed properly in places with abundant wind resources or that maintenance and repair are not performed properly. In particular, Korea has a complex topography, so more careful selection is required when selecting a location for a wind power plant.

The present invention has been made to solve the above-described problems, an object of the present invention is to provide a wind power plant site analysis system and method to easily understand the actual wind power plant site by considering a number of factors to consider when selecting a location. will be.

Finally, it includes a wind power plant site analysis device that generates overlapping analysis data showing location scores for regions in consideration of weights by location selection factors.

The location selection factors have a great influence on wind power generators, but they are natural factors that cannot be changed by humans, environmental protection factors to consider areas that are to be protected or legally restricted in terms of environment, and considering the interaction between wind power plants and humans. It may include human injury factors and economic factors that are important to companies building wind farms.

The wind power plant location analysis device comprises a location data standard matching unit for matching the standards of the plurality of location data by unifying the coordinate system of the plurality of location data to a predetermined coordinate system and the cell size of the GIS-based data; A location selection factor classification unit for classifying the plurality of location data by location selection factors, a rating determination unit for determining a rating of the plurality of location data and assigning a score according to the location selection factors, and regions in consideration of weights for each location selection factor It may include a superimposed analysis data generation unit for generating the superimposed analysis data in which location scores for.

The predetermined coordinate system is a TM (Transverse Mercator) coordinate system, the cell size may be unified to 100mx100m.

The location selection factor classification unit may classify the plurality of location data for each location selection factor.

The grade determining unit may determine a grade of the plurality of location data as a total of three grades representing very suitable, normal, and inadequate, and may assign a score of 5, 3, and 1 to each grade.

The apparatus for analyzing a wind power plant propagation may include a factor-based weight providing unit configured to determine a weight for each location selection factor according to an AHP (Analytic Hierarchy Process) technique to provide weight information for each location selection factor.

Generating a step.

In the case of a wind turbine, once moved, it is almost impossible to move the site. Therefore, although location selection is very important in the case of wind power plants, much research on the location selection of wind power plants has not been conducted in Korea.

According to the present invention, various factors to be considered in selecting a location of a wind power plant can be considered simultaneously using AHP and GIS without the need to consider each separately. In addition, the distribution of the area derived from the site can be immediately confirmed, and it is easy to grasp the characteristics of the place.

In the following description, well-known functions or constructions are not described in detail to avoid unnecessarily obscuring the subject matter of the present invention.

In addition, the size of each component in the drawings may be exaggerated for the sake of explanation and does not mean a size actually applied.

Hereinafter, with reference to the accompanying drawings will be described the configuration and operation of the present invention.

1 is a block diagram of a wind power plant analysis system according to the present invention.

The wind power plant load analysis system includes a plurality of location data providing devices 110 to 130 and a wind power plant load analysis device 200.

The plurality of location data providing devices 110 to 130 may provide the plurality of location data to the wind power plant loading analysis device 200. The plurality of location data providing apparatuses 110 to 130 are respectively located in various places such as the Korea Meteorological Agency, the National Aeronautics and Space Administration (NASA) satellite, the Water Management Information System (WAMIS), the Forest Service, the Ministry of Environment, the National Park Service, and the National Security Administration. Can be located. For example, the data required for wind resource analysis may use a wind resource map of 1km × 1km resolution, produced by the Korea Meteorological Administration in 2009. DEM and Watershed data can be used to analyze valley angles and distances to ridges in topographical factors. DEM data for analyzing the valley angle can use NASA's SRTM30 satellite data, and for ridges, watershed data can use the WAMIS (Water Resource Information System) map. This is because the ridge determines that it acts as a watershed. Forest density data can refer to 'density' information among various information in 'Clinical map' of the Forest Service. For wind farm site analysis, these various location data can be used.

Here, the location data includes all data that can be used to determine the wind power plant destination according to the present invention, and is not limited to the examples described above. In addition, the location data means all raw data obtained in order to analyze the location of the wind power plant in the state where the wind power plant location is not determined in the present invention.

The wind power plant propagation analysis apparatus 200 provides a plurality of location data from the plurality of location data providing devices 110 to 130, that is, the first location data providing device 110 to the Nth location data providing device 130. Receive. When the wind power plant propagation analysis apparatus 200 receives the plurality of location data, the wind power plant propagation analysis apparatus 200 generates overlapping analysis data for the wind power plant propagation analysis. Specifically, the wind power plant site analysis device 200 matches the specifications of a plurality of location data, and classifies by location selection factors. Then, the wind power plant load analysis device 200 determines the grade of the location data and gives a score accordingly. Finally, the wind farm site analysis device 200 generates overlapping analysis data in which location scores for regions are considered in consideration of weights for location selection factors.

For this operation, the wind power plant analysis device 200 is the location data specification matching unit 210, location selection factor classification unit 220, rating determination unit 230, the user input unit 240, factor-specific weight providing unit 250, a superimposition analysis data generator 260 and a display 270.

The location data standard matching unit 210 receives a plurality of location data. The plurality of location data are generally map-related data, that is, data based on a geographic information system (GIS), and have different coordinate systems or cell sizes. The location data standard matching unit 210 unifies the coordinate system and the cell size to perform the overlap analysis. In the present invention, the coordinate system of the plurality of location data is unified to a predetermined coordinate system, for example, a TM (Transverse Mercator) coordinate system having a central origin, and the cell size of the GIS-based data is unified to 100m × 100m to match the specification of the location data. . The location data specification matching unit 210 provides the location selection factor classification unit 220 with a plurality of location matching data.

The location selection factor classification unit 220 classifies the plurality of input location data for each location selection factor. In the present invention, the factors to be considered when selecting the location of the wind power plant derived above were classified as shown in FIG.

2 is a diagram showing a hierarchical structure of factors for selecting a location of a wind power plant according to a preferred embodiment of the present invention.

Referring to Figure 2, based on the goal of selecting the location of the wind power plant (Level 1) to consider the natural factors that are greatly affected by the wind power generator, but difficult to change human, environmentally protected or legally restricted areas Environmental protection factors for humans, human damage factors for considering human interaction with wind power plants, and economic factors that are considered important for companies building wind power plants (Level 2). In addition, detailed categories (Level 3) were classified for each category. Natural factors were classified into wind resources, topography, and forest density, and environmental protection factors were classified into land use, conservation area, national park, and Baekdudaegan protected area. Human victims were classified as noise and shadow, and economic factors were classified as transmission line and access road.

Natural factors are primarily related to natural conditions and include items that are difficult to change by human power, such as wind resources, topography, and forest density. Specifically, since the wind resources are more practical to evaluate the wind resources with the amount of energy produced by the actual wind power generator than the wind speed, the present invention uses the wind density as an index for evaluating the wind resources. The topography is to consider the topographic factors affecting the wind flow. In the present invention, the topography factors the valley angle and the distance to the ridge. If the valley angle is large, the wind quality decreases due to the high probability of generating gusts or turbulence, which should be taken into consideration when selecting the location.The distance to the ridge is mainly considered in mountainous areas such as Gangwon-do, since the ridge is less intrusive. The element to do. The smaller the valley angle and the closer the ridge, the better the wind power generation. Forest density is considered under the premise that forests around wind turbines interfere with wind flow. Wind is greatly affected by surface roughness.

Environmental protection factors are considered because some environmental destruction is inevitable when installing wind turbines. For example, you need to cut down the trees where you want to build a wind turbine, and roads must be built to carry the materials needed to build a wind farm. In this respect, environmental protection factors must be taken into account in building wind power plants. Land use, among the items of environmental protection factors, is intended to reduce the environmental damage mentioned above by selecting areas with farmland or grass. Conserved areas are items that are considered in order to protect those areas that are considered to be protected. National park is a representative region of Korea's natural ecosystem and natural and cultural landscape, which is considered to prevent wind power plants from being installed. Baekdudaegan protected area is considered to protect the Baekdudaegan area that is deemed to need special protection.

Human injury factors include items that are difficult to locate in a wind farm for or by people. In the present invention, the noise and shadow that may be generated by the wind power generator as a human damage factor are considered. Noise is considered in order to maintain a certain distance from the residential area because the noise problem of wind turbines is on the rise. Also, shadows are considered items because the periodic shadows that wind turbines produce as they are thrown around people can be bothered and stressed.

Economic factors are considered because wind power needs to be economically viable. The transmission line represents the separation distance from the existing substation as a considered item because the power generated by the wind turbine must be connected to the power grid in order to be used. Access roads are considered because building a wind power plant requires a moving road to carry the wind turbines.

The location selection factor classification unit 220 classifies a plurality of location data hierarchically into a plurality of location selection factors including natural factors, environmental protection factors, human damage factors, and economic factors as described above. The location selection factor classifying unit 220 provides the classified location data for each location selection factor to the class determining unit 230.

Meanwhile, the factor-based weight providing unit 250 determines the weight for each factor according to the AHP (Analytic Hierarchy Process) technique and provides the weight to the location model generator 260.

AHP, one of the multi-criteria decision making methods, was developed by Professor Thomas Saaty of the University of Pennsylvania in the early 1970s. The most basic AHP hierarchy is in the form of targets at the top of the hierarchy, below which the evaluation criteria are based, and at the bottom of the hierarchy, more detailed and specific (Bryson, 1996).

The importance of factors to be considered in determining the location of a wind power plant determined using AHP is, for example, 0.65 (65%) for natural factors, 0.19 (19%) for economic factors, 0.11 (11%) for environmental protection, and human damage. The factor is determined to be 0.05 (5%).

The importance, or weight, of these factors was determined by applying the AHP technique based on a survey from wind power specialists, manufacturers or operators. A program for calculating weights according to the AHP technique is under the trade name Expert Choice 2000. In terms of importance by factor, economic factors are more important than environmental protection factors, indicating that the city or province operating a wind power plant cannot be free from economics. Too much suggests that there may be difficulties in the location of wind power plants. The reason for the low rate of human damage is that noise or shadow can be solved by a certain distance or more, and noise is expected to be solved as soon as possible due to technological development.

In addition, the factor-based weight providing unit 250 has weight information on items of each location selection factor. Specifically, the importance of each item of Level 3 derived according to the AHP method is shown in FIG. 3. Referring to FIG. 3, natural factors were found to have high importance in order of wind resources, topography, and forest density. In other words, wind resources (68%) showed the highest importance, followed by distance to ridge (16%), valley angle (9%), and forest density (7%). Compared to other factors, wind resources showed a relatively high importance, because wind resources are the most fundamental for building wind power plants. In terms of environmental protection factors, land use, national parks, Baekdudaegan protected areas, and preserved areas were most important.

In terms of environmental protection factors, land use (41%) was the most important, and national parks (27%) and Baekdudaegan protected areas (22%) were similarly high, while conservation areas (10%) were the least important. Appeared to have. Land use has been found to be of greater importance than other factors, where environmental damage can be minimal and licensed if a suitable area for wind turbines has already been used for fields or grasslands. Because it is easy to. The next major importance of national parks is that national parks are currently forbidden to install wind power generators. Baekdudaegan protected areas, like the national parks, are expected to be of lower importance than the national parks because they are protected by biodiversity and have excellent natural values. In the case of the conservation area, it is intended to protect the area that is considered to be protected value nationally.In order to preserve the area with high conservation value through ecological natural map that divides the whole country from class 1 to class 3 according to the natural environment conservation law. It is. However, the level of importance was low because no legal restrictions or prohibitions were imposed on the class.

In human damage factors, noise (50%) and shadow (50%) are equally important. This seems to be because both factors should be considered as important factors that negatively affect the population. Finally, in terms of economic factors, transmission lines (62%) are more important than access roads (38%). This is where wind power plants generate electricity, so it is important to reduce losses in terms of power, and thus, transmission lines carrying electricity seem to be more important.

As described above, the factor-based weight providing unit 250 has weight information for each location selection factor, and provides weight information for each location selection factor to the overlapping analysis data generation unit 260. Since the weight can be changed according to the times and circumstances, the location analysis model generating apparatus 200 includes a user input unit 240 for allowing the user to set the weight. Through the user input unit 240, the user may change weights for the location selection factors of the wind power plant.

On the other hand, the rating determiner 230 determines the rating for the location data for each location selection factor and gives a score accordingly. In order to perform overlapping analysis based on each location data, it is necessary to prepare an appropriateness grade and to create a classification criteria that matches the grade for each factor. In the present invention, the appropriateness grade is divided into a total of three grades (very suitable, moderate, inadequate) to give a score. The most suitable condition for building a wind power plant by each factor is 'very suitable', and the condition which is not the best condition but seems to be possible to position the wind power plant through some adjustment is 'moderate'. The conditions under which the effect is expected to be classified as 'inadequate', 5 points for 'very suitable', 3 points for 'normal' and 1 point for 'non'. One point is given even if the condition of 'poor' is not good because it is not good condition at present, but it may be possible to position the wind power plant due to technical development or problem solving in the future.

In the present invention, 1, 3, 5 points are given to each grade in the case that the grades are divided into multiple analysis results can be subdivided by only one point difference, but when the number of grades is small, the score is given only by one point difference. This is because the results of analysis can be spread out over a wide range, making it difficult to derive quite a few. In fact, giving 1, 2, or 3 points resulted in an overly wide area (1,045.13㎢), making it difficult to give meaning. However, as a result of assigning scores of 1, 3, and 5 points, the difference between the points with high and low points resulted in a relatively small area (30.36㎢).

Specifically, the rating determiner 230 determines the rating of location data as shown in FIG. 4 for natural factors.

The grade determination unit 230 determines the grade of the location data as shown in FIG. 5 with respect to environmental protection factors. In addition, the grade determination unit 230 determines the grade of the location data as shown in FIG. 6 for the human damage factor and determines the grade of the location data as shown in FIG. 7 for the economic factor. The rating determiner 230 provides location data rating information to the overlapping analysis data generator 260 when the rating of the location data is determined.

The nested analysis data generation unit 260 generates overlapping analysis data for each location selection factor, and then generates overlapping analysis data by overlapping overlapping data for each location selection factor.

In detail, the overlap analysis data generation unit 260 may generate overlap analysis data for each location selection factor, that is, natural factors, environmental protection factors, human damage factors, and economic factors. In addition, the superimposition analysis data generation unit 260 may generate final superimposition analysis data by integrating the superimposition analysis data for each location selection factor.

For example, the superimposition analysis data generator 260 assigns the weights provided by the weighting unit 250 for each factor to the score according to the grade of the location data for each of the sub-items of the natural factors, as shown in FIG. 8. Generate overlay analysis data in which location scores appear. Referring to FIG. 8, the overlapping analysis data generated by weighting the location data of natural factors by 68% for wind density, 9% for valley angle, 16% for distance to ridge, and 7% for forest density is Is shown. Given the largest weighting of wind density, it shows the distribution closest to the wind density of the four input rasters. Through Figure 8 it can be seen that the areas that received high scores, such as 4 points, 5 points appear mostly along the Taebaek Mountains stem. The three-point area also appears around the four- and five-point areas.

We can know the area of each factor and the score area of the natural factors derived by combining the four elements by weight. It can be seen that the area of 5 points in wind density and valley angle is larger than the area of 5 points in distance to ridge and forest density. In terms of the area of natural factors that resulted from combining the four elements, the area that received five points was small at 42.36㎢, while the area that received four points was 1,041.73㎢. A total of 1,914.66 ㎢ in total with an average score of 3 points or more is relatively large, which satisfies the natural factors.

In addition, the superimposition analysis data generation unit 260 assigns the weights provided from the weighting unit 250 for each factor to the points according to the grades of the location data for each of the sub-factors of the environmental protection factor, and thus, the regions as shown in FIG. 9. Generate overlapping analysis data showing location scores for. Referring to FIG. 9, the overlapping analysis data generated by weighting the location data of environmental protection factors by 41% for land use, 10% for conservation areas, 27% for national parks, and 22% for Baekdudaegan protected areas. Is shown. Most of the areas are represented by 3 points, and 4 and 5 areas are partially represented. The lowest scores in environmental protection are located in the national parks and Baekdudaegan protected areas, mainly along the Taebaek Mountains. Conversely, regions with high scores on natural factors have lower scores on environmental protection factors, suggesting that the regions with good wind resources have high environmental value.

In this manner, the superimposition analysis data generator 260 assigns the weights provided by the weighting unit 250 for each factor to the sub-factors of the human damage factor and the economic factor to the regions. Generate overlapping analysis data showing location scores for.

Then, the superimposition analysis data generation unit 260 according to the AHP analysis result of the superimposition analysis data of the four factors, 65% for natural factors, 11% for environmental protection factors, 5% for human damage factors, economic factors Overlapping with a weight of 19% produces the final overlap analysis data as shown in FIG. 10.

FIG. 10 is a diagram illustrating final overlap analysis data obtained by superimposing overlap analysis data of four factors according to an embodiment of the present invention.

Referring to FIG. 10, it can be seen that the 4 points and 5 points of the final overlap analysis data are high wind density areas. This shows that the wind density is important when selecting the location of the wind power plant. In addition, the 4 and 5 points are mostly concentrated in the Taebaek Mountain Range, so it can be seen that the Taebaek Mountain Range is a very favorable area for wind power generation in Gangwon-do. The three-point area is mainly distributed along the ridge, indicating that the ridge is also a favorable area for wind power generation. The final overlap analysis data is provided to the display unit 270 and displayed on the display unit 270.

The operation of the wind power plant load analysis device will be described with reference to FIG.

11 is a flowchart showing the operation of the wind power plant load analysis device according to an embodiment of the present invention.

Referring to FIG. 11, the apparatus for analyzing wind power loads first determines whether location data is received in step 910. When the location data is received, the wind power plant loading analysis device matches the specifications of the location data in step 920. Since the location data are different from the coordinate system or cell size as the GIS data as described above, the wind power plant site analysis unit unifies the coordinate system of the plurality of location data into a TM (Transverse Mercator) coordinate system having a central origin and cell size. Matches the location data specification by unifying 100m x 100m.

Subsequently, the wind power plant loading analysis device classifies the plurality of location data input in step 930 by location selection factors. Therefore, location data is classified into natural factors, environmental protection factors, human damage factors and economic factors (Level 2), and natural factors are classified into wind resources, topography, and forest density, and environmental protection factors are land. It is classified into use, conservation area, national park, and Baekdudaegan protection area. Human victims are classified as noise and shadow, and economic factors are classified as transmission line and access road.

Subsequently, the wind power plant loading analysis device determines the grade of the location data in step 940 and assigns a score accordingly. In the present invention, the appropriateness grade is divided into a total of three grades (very suitable, moderate, inadequate) to give a score.

Then, in step 950, the wind farm load analysis device generates overlapping analysis data in consideration of the weight for each location selection factor. Specifically, the wind power plant site analysis device assigns the weights provided from the weighting unit 250 for each factor to a score according to the grade of location data for each of the natural factors, environmental protection factors, human damage factors, and economic factors. To generate overlapping analysis data showing location scores for the regions. In addition, the wind farm load analysis device weighted 65% for natural factors, 11% for environmental protection factors, 5% for human damage factors, and 19% for economic factors, according to the results of the previous AHP analysis of the four factor overlapping analysis data. Subject overlap to produce the final overlap analysis data as shown in FIG. 10. The wind farm load analysis device provides the user with the final overlay analysis data in step 960. For example, the overlapping analysis data may be displayed on the display unit and provided to the user.

In the foregoing detailed description of the present invention, specific examples have been described. However, various modifications are possible within the scope of the present invention. The technical spirit of the present invention should not be limited to the above-described embodiments of the present invention, but should be determined by the claims and equivalents thereof.
