[0002] For example, Patent Document 1 discloses a technique for selecting suitable sites suitable for installing any wind power generation facility based on average wind speed data, elevation data, land use data, and digital map data. [Prior Art Documents] [Patent Documents]

[0003] [Patent Document 1] Japanese Patent No. 3242606 [Summary of the Invention] [Problem to be Solved by the Invention]

[0004] However, with the technique described in Patent Document 1, it is necessary to acquire data necessary for estimating average wind speed data (such as meteorological office wind speed data) from the Japan Meteorological Agency, and acquire elevation data, land use data, and digital map data from the Geospatial Information Authority of Japan. That is, it is necessary to acquire data required for extracting suitable sites from a plurality of mutually different data supply sources. For this reason, it takes a great deal of time and effort to acquire the data necessary for extracting suitable sites. Furthermore, the above-mentioned data alone are insufficient for extracting suitable sites with high accuracy; wind speed information such as wind force, constraint information such as the habitat of golden eagles, and free capacity information such as the free capacity of transmission lines and substations are also required.

[0005] The present disclosure has been made in view of the above-mentioned problems, and an object thereof is to provide a suitable site extraction apparatus and a suitable site extraction program that can reduce the time and effort required to acquire data necessary for extracting suitable sites suitable for installing wind power generation facilities, and improve the extraction accuracy of suitable sites.

[0007] To achieve the above objective, the site selection program relating to this disclosure is a site selection program for selecting a site suitable for the installation of a wind power generation facility, and causes a computer to execute: a potential map acquisition process for acquiring a potential map from a first database that stores a potential map in which wind speed information is assigned to a map; a constraint map acquisition process for acquiring a constraint map from a second database that stores a constraint map in which constraint information that restricts the installation of the wind power generation facility is assigned to a map; a free capacity map acquisition process for acquiring a free capacity map from a third database that stores a free capacity map in which free capacity information of the power grid is assigned to a map; an integrated database construction process for constructing an integrated database in which the potential map acquired in the potential map acquisition process, the constraint map acquired in the constraint map acquisition process, and the free capacity map acquired in the free capacity map acquisition process are stored; and a superposition process for superimposing the potential map, the constraint map, and the free capacity map stored in the integrated database onto a map image.

[Modes for carrying out the invention]

[0010] Hereinafter, a suitable site selection device and a suitable site selection program according to embodiments of this disclosure will be described with reference to the drawings. Such embodiments represent one aspect of this disclosure and are not limiting, and can be modified at will within the scope of the technical idea of ​​this disclosure.

[0011] <Suitable Site Extraction Device> The site selection device according to this disclosure extracts suitable sites (hereinafter simply referred to as "suitable sites") for the installation of wind power generation facilities. Figure 1 is a schematic diagram showing the configuration of a site selection system 100 including a site selection device 1 according to one embodiment. As illustrated in Figure 1, the site selection system 100 includes a first database 110, a second database 120, a third database 130, and a site selection device 1.

[0012] The suitable location extraction device 1 is a computer, which may be a stationary terminal such as a desktop computer terminal, or a portable terminal such as a smartphone or tablet terminal. Figure 2 is a diagram showing an example of the hardware configuration of the suitable location extraction device 1 according to one embodiment. As illustrated in Figure 2, the suitable location extraction device 1 includes, for example, a processor 160, RAM 162 (Random Access Memory), ROM 164 (Read Only Memory), HDD 166 (Hard Disk Drive), input I / F 168, output I / F 170, and display 180, which are connected to each other via a bus 172. In one embodiment, as illustrated in Figure 1, the suitable location extraction device 1 (terminal) has an application Ap, which is a program for extracting suitable locations, pre-installed. This application Ap operates in QGIS, which is one of the general geographic information system software. The suitable location extraction device 1 realizes each functional part of the suitable location extraction device 1 by loading the application Ap installed in ROM 164 into RAM 162 and executing it with the processor 160. Each functional part of the suitable site extraction device 1 (such as the potential map acquisition unit 2) will be described later. Note that this disclosure does not limit the geographic information system software to QGIS. The geographic information system software may be other than QGIS, such as ArcGIS.

[0013] In the embodiment illustrated in Figure 1, the suitable location extraction device 1 can acquire information from the first database 110, the second database 120, and the third database 130 via the Internet 150, which is one of the communication networks. However, this disclosure is not limited to the Internet 150 as the communication network.

[0014] The first database 110 stores a potential map Map 1 in which wind speed information D1 is assigned to the map. Figure 3 shows an example of a potential map Map 1 according to one embodiment. Specifically, as illustrated in Figure 3, the potential map Map 1 has a mesh of a predetermined size (for example, a 5m mesh) superimposed on the map, and wind speed information D1 is assigned to each rectangular section 111 that constitutes the mesh. In one embodiment, the wind speed information D1 is wind force. More specifically, the wind speed information D1 is so-called wind potential, for example, the average wind force at a predetermined height from the ground. The sections 111 are colored according to the wind potential, and in the form illustrated in Figure 3, the darker the color of the section 111, the greater the wind potential. Such a potential map Map 1 can be obtained, for example, from the Renewable Energy Potential System (REPOS) published by the Ministry of the Environment. Note that this disclosure does not limit the wind speed information D1 to wind potential. For example, potential map Map1 may be assigned wind speed information D1 other than wind potential, such as maximum wind power. Potential map Map1 may include a first potential map Map1 to which wind potential is assigned and a second potential map Map1 to which maximum wind power is assigned.

[0015] The second database 120 stores a constraint map Map2 in which constraint information D2 that constrains the installation of wind power generation facilities on a map is assigned. FIG. 4 is a diagram showing an example of the constraint map Map2 according to an embodiment. Specifically, as illustrated in FIG. 4, in the constraint map Map2, a mesh of a predetermined size (for example, a 5 m mesh) is superimposed on the map, and the constraint information D2 is assigned to each rectangular section 111 constituting the mesh. In one embodiment, the constraint information D2 includes information related to the natural environment. More specifically, the information related to the natural environment is the distribution of rare animals and plants, for example, the distribution of national forests and golden eagles. As illustrated in FIG. 4, the sections 111 are superimposed on the map so as to be identifiable when they have the constraint information D2. The constraint map Map2 can be acquired, for example, from the Environmental Impact Assessment Database System (EADAS) published by the Ministry of the Environment. Note that the potential map Map1 and the constraint map Map2 may be partitioned by meshes of the same size as each other, or may be partitioned by meshes of different sizes from each other. The information related to the natural environment is not limited to the distribution of rare animals and plants, and may be bird migration routes or private forests. In the present disclosure, a case where the constraint map Map2 includes a first constraint map Map2 to which the distribution of national forests is assigned and a second constraint map Map2 to which private forests are assigned will be described as an example.

[0016] In some embodiments, the constraint information D2 includes information related to the social environment in addition to the information related to the natural environment. In some embodiments, the constraint information D2 includes information related to the social environment instead of the information related to the natural environment. The information related to the social environment is the location of environmental conservation areas, for example, the location of existing or planned wind power plants, the location of roads, and the location of conservation areas such as wildlife sanctuaries and quasi-national parks.

[0017] The third database 130 stores a capacity map Map3 in which power system available capacity information D3 is mapped to a map. FIG. 5 is a diagram showing an example of the available capacity map Map3 according to an embodiment. In one embodiment, the available capacity information D3 includes the available capacity of a power transmission line and the distance from the power transmission line. Specifically, as illustrated in FIG. 5, in the available capacity map Map3, a substation symbol S1 indicating a substation and a power transmission line symbol S2 indicating a power transmission line are superimposed on the map. Further, the power transmission line symbol S2 includes an available power capacity (for example, 100 MW). The available capacity map Map3 can be acquired from, for example, a website of an electric power company.

[0018] In some embodiments, the available capacity information D3 includes the available capacity of a power transmission line, the available capacity of a substation, and the distance from the power transmission line. In some embodiments, the available capacity information D3 consists of the available capacity of a substation and the distance from the power transmission line. In these cases, the substation symbol S1 includes an available power capacity (for example, 100 MW).

[0019] Each functional unit of the suitable site extraction device 1 will be described. In one embodiment, as shown in FIG. 1, the suitable site extraction device 1 includes a potential map acquisition unit 2, a constraint map acquisition unit 4, an available capacity map acquisition unit 6, an integrated database construction unit 8, a map image display unit 10, a condition setting unit 12, a mask layer creation unit 14, and a superimposing unit 16.

[0020] The potential map acquisition unit 2 acquires the potential map Map1 from the first database 110 via the Internet 150. The constraint map acquisition unit 4 acquires the constraint map Map2 from the second database 120 via the Internet 150. The available capacity map acquisition unit 6 acquires the available capacity map Map3 from the third database 130 via the Internet 150.

[0021] The timing at which each of the potential map Map1, constraint map Map2, and free capacity map Map3 is acquired is not particularly limited. For example, the potential map Map1, constraint map Map2, and free capacity map Map3 are automatically acquired when the site selection device 1 (terminal) or QGIS is started or when application Ap is activated. Another example is when the site selection device 1 includes a batch file that instructs the site selection device 1 to acquire the potential map Map1 from the first database 110. Yet another example is when application Ap displays a button (not shown) on the site selection device 1's display 180 that, when pressed by the user, instructs the potential map acquisition unit 2 to acquire the potential map Map1. In other words, the potential map Map1 is acquired when the user presses the button. The same applies to the constraint map Map2 and free capacity map Map3; they may be acquired when the batch file is executed or when the button is pressed.

[0022] The integrated database construction unit 8 constructs an integrated database 3 in which the potential map Map1 acquired by the potential map acquisition unit 2, the constraint map Map2 acquired by the constraint map acquisition unit 4, and the free capacity map Map3 acquired by the free capacity map acquisition unit 6 are stored. In other words, the potential map Map1, the constraint map Map2, and the free capacity map Map3 are stored in a single integrated database 3. In some embodiments, each of the potential map Map1, the constraint map Map2, and the free capacity map Map3 is corrected to a common format before being stored in the integrated database 3.

[0023] The map image display unit 10 displays the map image IM on the display 180. The map image IM may be obtained in advance from, for example, the Ministry of Land, Infrastructure, Transport and Tourism's website, or it may be created in advance by an engineer operating QGIS. Figure 6 is a diagram showing an example of a map image IM according to one embodiment. In one embodiment, as illustrated in Figure 6, when application Ap is activated, an operation screen Sc1 for the user to operate application Ap is displayed on the display 180.

[0024] In the configuration illustrated in Figure 6, the operation screen Sc1 includes a toolbar section 20 where icons 26 of the functions of the application Ap are arranged, a workspace section 22 where a map image IM is displayed, and a layer display section 24 where layers R to be superimposed on the map image IM displayed in the workspace section 22 are displayed. Layer R includes the potential map Map1, constraint map Map2, and free capacity map Map3 described above. Layer R further includes conditional maps (conditional potential map Map11, conditional constraint map Map12, and conditional free capacity map Map13) and a mask layer 30, which will be described later. The layer display section 24 includes checkboxes 28 that allow the user to select whether or not to superimpose the various layers R described above onto the map image IM.

[0025] The condition setting unit 12 allows the user to set conditions for at least one of the wind speed information D1, constraint information D2, and available capacity information D3. In one embodiment, the condition setting unit 12 displays a condition setting screen Sc2 on the display 180, which allows the user to set conditions for each of the wind speed information D1, constraint information D2, and available capacity information D3. The condition setting screen Sc2 may be displayed on the display 180 by pressing, for example, an icon 26 arranged on the toolbar unit 20, or by selecting it from a menu bar (not shown).

[0026] Figure 7 shows an example of a condition setting screen Sc2 according to one embodiment. As illustrated in Figure 7, the condition setting screen Sc2 includes a wind speed information condition area E1 for setting conditions for wind speed information D1, a constraint information condition area E2 for setting conditions for constraint information D2, and a free capacity information condition area E3 for setting conditions for free capacity information D3.

[0027] In the wind speed information condition area E1, a wind potential text box 32 is formed where a limit value for the wind potential can be entered. In the configuration illustrated in Figure 6, "7.0" is entered in the wind potential text box 32, and the potential map Map1, to which a wind potential of 7.0 m / s or higher is assigned, is set to be superimposed on the map image IM.

[0028] The constraint information condition area E2 contains a constraint list box 34 for selecting a constraint map Map2 to be superimposed on the map image IM. In the configuration illustrated in Figure 7, constraint map Map2 assigned to the distribution of national forests and constraint map Map2 assigned to the distribution of private forests are selected. The constraint information condition area E2 also contains an Add button 36 that allows the addition of any constraint map Map2 when pressed, and a Remove button 38 that deletes a constraint map Map2 when pressed.

[0029] The available capacity information condition area E3 contains a available capacity text box 40, an N1 electric control usable amount text box 42, a available capacity + N1 electric control capacity text box 44, and a distance specification box 46. Each of these has a checkbox, and when one of these checkboxes is checked, the entered value becomes valid as a condition.

[0030] The available capacity text box 40 is entered with the capacity that the transmission line can accept. In the configuration illustrated in Figure 7, "20.00" is entered in the available capacity text box 40, and the available capacity map Map3, which is assigned to transmission lines with an available capacity of 20.00 MW or more (with the transmission line symbol S2 superimposed), is set to be superimposed on the map image IM.

[0031] The N1 power control capacity text box 42 is where the power transmission capacity in the event of a transmission line failure is entered. The available capacity + N1 power control capacity text box 44 is where the total value obtained by adding the power transmission capacity in the event of a transmission line failure to the capacity that the transmission line can accept is entered.

[0032] The distance specification box 46 is used to input the distance from the power line. In the configuration shown in Figure 7, "100.00" is entered in the distance specification box 46, and the available capacity map Map3, which extracts the area within 100.00m of the power line, is set to be superimposed on the map image IM.

[0033] In the configuration illustrated in Figure 7, the available capacity information condition area E3 further includes a power system checkbox 48 for selecting whether or not to set a condition in the available capacity information D3, a name text box 50 for naming the condition set in the available capacity information D3, and an output control checkbox 52 for selecting whether or not output control may occur under normal circumstances.

[0034] In the configuration illustrated in Figure 7, the condition setting screen Sc2 has a save button 54 that, when pressed, saves all of the conditions for wind speed information D1 set in the wind speed information condition area E1, the constraint information D2 set in the constraint information condition area E2, and the free space information D3 set in the free space information condition area E3.

[0035] In the configuration illustrated in Figure 7, the condition setting screen Sc2 further includes a read button 56 that, when pressed, reads from the integrated database 3 the following: potential map Map1 (hereinafter referred to as conditional potential map Map11) to which wind speed information D1 of the conditions set in wind speed information condition area E1 is assigned; constraint map Map2 (hereinafter referred to as conditional constraint map Map12) selected in constraint information condition area E2; and free capacity map Map3 (hereinafter referred to as conditional free capacity map Map13) to which free capacity information D3 of the conditions set in free capacity information condition area E3 is assigned.

[0036] The mask layer creation unit 14 creates a mask layer 30 from which an arbitrary range has been extracted from the map image IM displayed on the display 180. An example of how to create the mask layer 30 will be described with reference to Figures 6 and 7.

[0037] As illustrated in Figure 6, the user selects the area (referred to as the mask layer range 31) on the map image IM displayed on the operation screen Sc1 where they want to create the mask layer 30. Then, with the mask layer range 31 selected, the user displays the condition setting screen Sc2 on the display 180.

[0038] As illustrated in Figure 7, the condition setting screen Sc2 further includes a mask layer area E4. The mask layer area E4 has a text box 58 for naming the selected mask layer range 31 as the mask layer 30, and a mask layer creation button 60 that, when pressed, creates the mask layer 30 of the selected mask layer range 31.

[0039] In the configuration illustrated in Figure 7, the mask layer region E4 further includes a mask layer selection list box 62 for selecting any mask layer 30 from the created mask layers 30, and a mask layer check box 64 for selecting whether or not to superimpose the conditional potential map Map 11 and the conditional constraint map Map 12 onto the mask layer 30 selected in the mask layer selection list box 62.

[0040] The overlay unit 16 overlays at least one of the potential map Map1, constraint map Map2, and free capacity map Map3 stored in the integrated database 3 onto the map image IM. In one embodiment, when the OK button 66 formed on the condition setting screen Sc2 is pressed, the overlay unit 16 overlays each of the potential map Map1, constraint map Map2, free capacity map Map3, conditional potential map Map11, conditional constraint map Map12, and conditional free capacity map Map13 onto the map image IM. As illustrated in Figure 6, the various maps overlaid on the map image IM are displayed as layers R as described above in the workspace unit 22. The operation screen Sc1 displays the map image IM with the layer R overlaid, which has a checkbox 28 checked (in Figure 6, the checkbox 28 for "●●●" corresponding to the mask layer 30 is checked).

[0041] In one embodiment, the superimposing unit 16 is configured to integrate multiple constraint maps Map2 selected in the constraint information condition area E2 and superimpose them onto the map image IM. As illustrated in Figure 6, the superimposing unit 16 superimposes an exclusion area map Map20 onto the map image IM, which is an integrated conditional constraint map Map12 to which the distribution of national forests is assigned and a conditional constraint map Map12 to which the distribution of private forests is assigned.

[0042] The superimposing unit 16 is configured to combine any map from a plurality of maps and superimpose it onto the map image IM. In one embodiment, the superimposing unit 16 generates a fused map Map 30 by fusing a conditional potential map Map 11 with a conditional constraint map Map 12 and superimposing it onto the map image IM.

[0043] In one embodiment, the superimposing unit 16 generates an extracted map Map 40 (displayed as "Fusion + xxx (power lines)" in the layer display unit 24) by fusing the conditional free capacity map Map 13 with the fused map Map 30 and superimposing it onto the map image IM.

[0044] In one embodiment, the superimposing section 16 is configured to prevent the superimposing of the conditional potential map Map 11 and conditional constraint map Map 12 outside the mask layer 30 when the OK button 66 is pressed while the mask layer checkbox 64 is checked. In other words, it limits the range of the conditional potential map Map 11 and conditional constraint map Map 12 read from the integrated database 3. In some embodiments, the superimposing section 16 is configured to prevent the superimposing of the potential map Map 1 and constraint map Map 2 outside the mask layer 30.

[0045] An example of extracting a suitable location using the aforementioned suitable location extraction device 1 will now be described. Figures 8 to 10 are examples of map images IM according to one embodiment. The map image IM shown in Figure 8 has an exclusion area map Map 20 superimposed on it. The map image IM shown in Figure 9 has a fusion map Map 30 superimposed on it. The map image IM shown in Figure 10 has an extraction map Map 40 superimposed on it.

[0046] In the configuration illustrated in Figure 8, the "Excluded Area" checkbox 28 is checked, and the excluded area map Map 20 is superimposed on the portion of the map image IM enclosed by the mask layer 30. In other words, the operation screen Sc1 displays (extracts) the first suitable area X1 (the white area within the mask layer 30 in Figure 8), where neither national nor private forests are distributed.

[0047] In the configuration illustrated in Figure 9, the "Fusion" checkbox 28 is checked, and the fused map Map 30 is superimposed on the portion of the map image IM enclosed by the mask layer 30. In other words, the operation screen Sc1 displays (extracts) the second suitable site X2 (the black area within the mask layer 30 in Figure 9), which is one of the first suitable sites X1 and has a wind potential of 7.0 m / s or more.

[0048] In the configuration illustrated in Figure 10, the "Fusion + xxx (power transmission line)" checkbox 28 is checked, and the extracted map Map 40 is superimposed on the area enclosed by the mask layer 30 in the map image IM. In other words, the operation screen Sc1 displays (extracts) the third suitable site X3 (the darker area within the mask layer 30 in Figure 10), which is within 100m of the second suitable site X2 and has a free capacity of 20.00MW or more from a power transmission line. Note that the map image IM shown in Figure 10 is displayed enlarged compared to the map image IM shown in Figures 8 and 9.

[0049] (Effects / Actions) The operation and effects of a suitable site extraction device 1 according to one embodiment will be described. According to one embodiment, an integrated database 3 is automatically constructed in which a potential map Map1 to which wind speed information D1 is assigned, a constraint map Map2 to which constraint information D2 is assigned, and a free capacity map Map3 to which free capacity information D3 is assigned are stored. As a result, the work of acquiring wind speed information D1, constraint information D2, and free capacity information D3 is unnecessary, and the effort required to acquire the data necessary for extracting suitable sites can be reduced.

[0050] According to one embodiment, a map image IM is generated in which the potential map Map1, constraint map Map2, and available capacity map Map3 are superimposed. Therefore, suitable locations can be extracted based on wind speed information D1, constraint information D2, and available capacity information D3. Thus, the accuracy of suitable location extraction can be improved.

[0051] According to one embodiment, by creating a mask layer 30 on the map image IM, suitable locations can be extracted from any range on the map image IM. Furthermore, according to one embodiment, since the potential map Map1 and constraint map Map2 are not superimposed outside the mask layer 30, the superimposition of unnecessary potential map Map1 and constraint map Map2 on the map image IM can be suppressed. In addition, the time required for the process of superimposing potential map Map1 and constraint map Map2 on the map image IM can be shortened.

[0052] According to one embodiment, a suitable location can be extracted via the condition setting screen Sc2, reflecting at least one of the following: wind speed information D1 with set conditions, constraint information D2 with set conditions, and available capacity information D3 with set conditions.

[0053] According to one embodiment, the layer display section 24 of the operation screen Sc1 is provided with checkboxes 28 that allow the user to select whether or not to superimpose various layers R, such as a conditional potential map Map 11, onto the map image IM. This makes it possible to generate a map image IM with any combination of layers R.

[0054] According to one embodiment, by generating a map image IM on which an exclusion area map Map 20 is superimposed, suitable locations that take constraint information D2 into consideration (for example, a first suitable location X1 where the aforementioned national forests and private forests are not distributed) can be extracted.

[0055] According to one embodiment, by generating a map image IM on which the fused map Map 30 is superimposed, it is possible to extract suitable locations (for example, a second suitable location X2 among the first suitable location X1 described above, where the wind potential is 7.0 m / s or more) that take both wind speed information D1 and constraint information D2 into consideration.

[0056] According to one embodiment, by generating a map image IM on which the extracted map Map 40 is superimposed, it is possible to extract suitable locations that take into account all of the wind speed information D1, constraint information D2, and available capacity information D3 (for example, a third suitable location X3 from the second suitable location X2 mentioned above, which is within 100m of the power line and has an available capacity of 20.00MW or more).

[0057] <Suitable Site Selection Program> The site selection program relating to this disclosure is a site selection program that extracts suitable sites for the installation of wind power generation facilities, and causes a computer to execute: a potential map acquisition process that acquires a potential map from a first database that stores potential maps in which wind speed information is assigned to a map; a constraint map acquisition process that acquires a constraint map from a second database that stores constraint maps in which constraint information that restricts the installation of wind power generation facilities is assigned to a map; a free capacity map acquisition process that acquires a free capacity map from a third database that stores free capacity maps in which free capacity information of the power grid is assigned to a map; an integrated database construction process that constructs an integrated database in which the potential map acquired in the potential map acquisition process, the constraint map acquired in the constraint map acquisition process, and the free capacity map acquired in the free capacity map acquisition process are stored; and a superposition process that superimposes the potential map, constraint map, and free capacity map stored in the integrated database onto a map image.

[0058] The contents described in each of the above embodiments can be understood, for example, as follows:

[0059] [1] The site selection device (1) relating to this disclosure is A suitable site extraction device for extracting suitable sites (X1, X2, X3) for the installation of wind power generation facilities, A potential map acquisition unit (2) acquires the potential map (Map1) from a first database (110) which stores the potential map (Map1) on which wind speed information (D1) is assigned, A constraint map acquisition unit (4) acquires the constraint map from a second database (120) which stores a constraint map (Map2) in which constraint information (D2) that restricts the installation of the wind power generation facility is assigned to the map, A free capacity map acquisition unit (6) acquires the free capacity map (Map3) from a third database (130) which stores a free capacity map (Map3) in which free capacity information (D3) of the power grid is assigned to the map, An integrated database construction unit (8) constructs an integrated database (3) in which the potential map acquired by the potential map acquisition unit, the constraint map acquired by the constraint map acquisition unit, and the free space map acquired by the free space map acquisition unit are stored, The system includes an overlay section (16) on which the potential map, the constraint map, and the free capacity map stored in the integrated database can be superimposed onto the map image.
