[0017] First, the background of the present invention will be described. As the importance of renewable energy increases, installing small-scale hydroelectric power plants (micro hydroelectric power plants) plays an important role in meeting local energy demand. Patent Document 1 discloses a site search technology for finding suitable sites for large-scale hydroelectric power plants, but the rivers used are small and it does not find suitable sites for micro hydroelectric power plants, which are greatly affected by changes in river flow rate. Therefore, the hydroelectric power plant development system 1 judges the economic viability and sustainability of a micro-hydroelectric power plant based on a number of factors, and finds a suitable site for the micro-hydroelectric power plant.

[0018] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram illustrating a hardware configuration of a hydroelectric power plant development system 1 in this embodiment. 1, the hydroelectric power plant development system 1 is a system for determining a suitable site for a hydroelectric power plant based on the economics and sustainability of the hydroelectric power plant when developing the hydroelectric power plant. Here, the economics of the hydroelectric power plant in this embodiment refers to an evaluation of the balance between the costs and profits involved in the construction and operation of the hydroelectric power plant, and the sustainability of the hydroelectric power plant refers to an evaluation of continuous power generation and continuous electricity demand over a long period of time. The hydroelectric power plant development system 1 comprises an artificial satellite 3, a ground receiving station 5, and a hydroelectric power development device 7. The artificial satellite 3 orbits the Earth and captures observation images of the ground with an on-board imaging device. The artificial satellite 3 analyzes the Earth's surface using radar images acquired by a synthetic aperture radar (SAR). Specifically, the artificial satellite 3 uses the synthetic aperture radar (SAR) to irradiate microwaves onto the Earth's surface, receive reflected waves from the Earth's surface, and acquire radar images. The ground receiving station 5 is a communication facility that receives data from the artificial satellite 3, which associates the observation point, the photographing date and time, and the radar image. The hydroelectric power station development device 7 is a computer terminal that determines suitable sites for hydroelectric power stations based on the data obtained from the ground receiving station 5 .

[0019] FIG. 2 is a diagram illustrating an example of a hardware configuration of the hydroelectric power plant development device 7. As shown in FIG. As illustrated in FIG. 2, the hydroelectric power plant development device 7 has a CPU 200, a memory 202, a HDD 204, a network interface 206 (network IF 206), a display device 208, and an input device 210, and these components are connected to each other via a bus 212. The CPU 200 is, for example, a central processing unit. The memory 202 is, for example, a volatile memory, and functions as a main storage device. The HDD 204 is, for example, a hard disk drive device, and serves as a non-volatile storage device for storing computer programs and other data files. The network IF 206 is an interface for wired or wireless communication, and realizes communication with the shared server 6, for example. The display device 208 is, for example, a liquid crystal display. The input device 210 is, for example, a keyboard and a mouse. The hydroelectric power plant development device 7 may be a cloud server.

[0020] FIG. 2 is a diagram illustrating an example of the functional configuration of the hydroelectric power plant development device 7. As shown in FIG. 2, a hydroelectric power plant development program 70 is installed in the hydroelectric power plant development device 7. The hydroelectric power plant development program 70 has a stream extraction unit 700, an access route detection unit 702, a construction cost estimation unit 704, a power transmission cost calculation unit 706, a river width measurement unit 708, a power generation amount prediction unit 710, an economic feasibility determination unit 712, a flow rate stability evaluation unit 714, a power demand prediction unit 716, a sustainability determination unit 718, a suitable site determination unit 720, and an equipment selection unit 722. The construction cost estimation unit 704 has a convenience evaluation unit 7040 and a difficulty evaluation unit 7042, the power generation amount prediction unit 710 has a flow rate calculation unit 7100, and the flow rate stability evaluation unit 714 has a river width observation unit 7140. In addition, a part or the whole of the hydroelectric power plant development program 70 may be realized by hardware such as an ASIC, or may be realized by borrowing some of the functions of an OS (Operating System).

[0021] In the hydroelectric power plant development program 70, the small river extraction unit 700 extracts small rivers smaller than the river mark on the map as rivers used by hydroelectric power plants. Specifically, the small river extraction unit 700 extracts small rivers from the radar image acquired from the ground receiving station 5. More specifically, the small river extraction unit 700 extracts small rivers from the radar image based on the water and water depth detected by the microwaves of the artificial satellite 3. In this example, small rivers smaller than the river mark include, for example, small rivers in mountainous areas, and are not limited to rivers, but also agricultural irrigation channels, dams, and waterfalls. The access road detection unit 702 detects access roads to the small rivers extracted by the small river extraction unit 700. Specifically, the access road detection unit 702 identifies roads that can access the small rivers extracted by the small river extraction unit 700 based on road data in the radar image acquired by the ground receiving station 5. The construction cost estimating unit 704 estimates the cost required in the initial stage of constructing a hydroelectric power plant. The cost required in the initial stage is, for example, the cost of constructing a generator, a turbine, a power transmission facility, and a power plant building. Furthermore, the construction cost estimating unit 704 estimates the construction cost of the hydroelectric power plant based on the convenience of the access route evaluated by the convenience evaluation unit 7040 and the construction difficulty of the hydroelectric power plant evaluated by the difficulty evaluation unit 7042.

[0022] The convenience evaluation unit 7040 evaluates the convenience of the access route based on information about the access route detected by the access route detection unit 702. Specifically, the access route detection unit 702 evaluates the convenience of the access route based on whether the road is in a condition that allows easy passage for vehicles for the construction of the hydroelectric power plant and for maintenance after the construction of the hydroelectric power plant, its width, whether there are restrictions on vehicular traffic, and its connectivity to the surrounding road network. The difficulty assessment unit 7042 assesses the difficulty of constructing a hydroelectric power plant based on the topographical data around the small river extracted by the small river extraction unit 700. Specifically, the difficulty assessment unit 7042 assesses whether the topography and geology around the extracted small river are suitable for a hydroelectric power plant based on the radar image acquired from the ground receiving station 5. For example, the difficulty assessment unit 7042 assesses resistance to natural disasters such as landslides and earthquakes based on the topography and geology. The electricity transmission cost calculation unit 706 calculates the electricity transmission cost based on the distance and the electricity transmission capacity of the electricity transmission network.

[0023] The river width measuring unit 708 measures the river width of the small river extracted by the small river extraction unit 700. Specifically, the river width measuring unit 708 measures the river width of the small river by using microwaves. The power generation amount prediction unit 710 predicts the amount of power generation in a hydroelectric power plant that utilizes a small river, based on the flow rate calculated by the flow rate calculation unit 7100. The flow rate calculation unit 7100 calculates the flow rate of the extracted small river based on the actually measured flow rate and river width of the extracted small river at a specific time point and the river width of the extracted small river measured by the river width measurement unit 708. The economic efficiency determination unit 712 determines the economic efficiency of the hydroelectric power plant based on the construction cost, operation cost, and power generation amount of the hydroelectric power plant. Specifically, the economic efficiency determination unit 712 determines the economic efficiency based on the construction cost estimated by the construction cost estimation unit 704. Furthermore, the economic efficiency determination unit 712 determines the economic efficiency based on the power generation amount predicted by the power generation amount prediction unit 710. The operation cost is a cost necessary for operating and maintaining the hydroelectric power plant, and specifically includes the power transmission cost for transmitting the power generated by the hydroelectric power plant to the power demand area and the cost for maintenance. The cost for maintenance is estimated based on the maintainability that takes into account the convenience of the access route evaluated by the convenience evaluation unit 7040. The economic efficiency determination unit 712 determines the economic efficiency based on the power transmission cost and maintainability calculated by the power transmission cost calculation unit 706.

[0024] The river width observation unit 7140 observes the change in the river width measured by the river width measurement unit 708 . The flow rate stability evaluation unit 714 evaluates the stability of the flow rate of the small river extracted by the small river extraction unit 700 based on the change in river width observed by the river width observation unit 7140. Specifically, when the change in river width is within a specified value and the change within the specified value is maintained for a certain period of time, it is determined that the flow rate is stable. The sustainability determination unit 718 determines the sustainability of the hydroelectric power plant based on the flow rate of the small river used by the hydroelectric power plant and the predicted demand value for the electricity generated at the hydroelectric power plant. Specifically, the sustainability determination unit 718 determines sustainability based on the stability of the flow rate of the small river evaluated by the flow rate stability evaluation unit 714. Furthermore, the sustainability determination unit 718 determines sustainability of the hydroelectric power plant based on the medium- to long-term demand forecast value of the amount of power demand predicted by the power demand forecasting unit 716.

[0025] The power demand prediction unit 716 predicts the power demand in a demand area based on the type and size of facilities in the demand area for the power generated by the hydroelectric power plant. The types of facilities include, for example, homes, companies, factories, transportation facilities, public facilities, etc. The suitable site determination unit 720 determines a suitable site for a hydroelectric power plant based on the results of the determination by the economic feasibility determination unit 712 and the sustainability determination unit 718. Specifically, the economic feasibility determination unit 712 and the sustainability determination unit 718 determine small rivers that are determined to have water levels equal to or above the standard value as rivers to be used by the hydroelectric power plant, and determines the construction site of the hydroelectric power plant using the determined small rivers. The equipment selection unit 722 selects a turbine suitable for the hydroelectric power plant based on the power generation amount predicted by the power generation amount prediction unit 710.

[0026] FIG. 4 is a flowchart showing the overall operation (S10) of the suitable location search process according to this embodiment. 4, in step 100 (S100), the small river extraction unit 700 extracts small rivers smaller than the river display on the map based on the data acquired from the ground receiving station 5. Specifically, the small river extraction unit 700 accepts a target range for extracting small rivers specified by the user, and extracts small rivers from the radar image of the accepted target range. In step 105 (S105), the economic feasibility determination unit 712 determines the economic feasibility of a hydroelectric power plant that utilizes the small river extracted in S100. Specifically, the economic feasibility determination unit 712 determines the economic feasibility of the hydroelectric power plant based on the construction cost, operation cost, and power generation amount of the hydroelectric power plant that utilizes the small river that is a candidate for utilization. In step 110 (S110), the sustainability determination unit 718 determines the sustainability of the hydroelectric power plant that utilizes the small river extracted in S100. Specifically, the sustainability determination unit 718 determines the sustainability of the hydroelectric power plant based on the flow rate of the small river that is a candidate for utilization and the predicted demand value of electricity generated in the hydroelectric power plant that utilizes the small river. In step 115 (S115), if the economic viability and sustainability of all the small rivers extracted in S100 have been determined (S115: Yes), the process proceeds to S120, and if there are any small rivers that have not been determined (S115: No), the process proceeds to S105. In step 120 (S120), the suitable site determination unit 720 determines a suitable site for constructing a hydroelectric power plant utilizing a small river where the economic viability determined in S105 and the sustainability determined in S110 are equal to or greater than the reference values.

[0027] FIG. 5 is a flowchart showing the process (S20) for determining the economic feasibility of a hydroelectric power plant according to this embodiment. As shown in FIG. 5, in step 200 (S200), the difficulty evaluation unit 7042 evaluates the difficulty of constructing a hydroelectric power plant based on the topographical data around the small river extracted by the small river extraction unit 700. Furthermore, the access road detection unit 702 identifies roads that can access the small river extracted by the small river extraction unit 700 from the road data acquired by the ground receiving station 5. The convenience evaluation unit 7040 evaluates the convenience of the identified roads based on whether they are well maintained for vehicles to pass through, their width, the presence or absence of vehicle traffic restrictions, and their connectivity to the surrounding road network. The construction cost estimation unit 704 estimates the construction cost of the hydroelectric power plant based on the convenience of the access roads evaluated by the convenience evaluation unit 7040 and the construction difficulty of the hydroelectric power plant evaluated by the difficulty evaluation unit 7042. In step 205 (S205), the electricity transmission cost calculation unit 706 calculates the electricity transmission cost based on the distance and the electricity transmission capacity of the electricity transmission network. In step 210 (S210), the river width measurement unit 708 uses microwaves to measure the river width of the small river extracted by the small river extraction unit 700. The flow rate calculation unit 7100 calculates the flow rate of the small river based on the measured flow rate and river width of the extracted small river at a specific time point and the river width measured by the river width measurement unit 708. The power generation amount prediction unit 710 predicts the power generation amount in a hydroelectric power plant that utilizes a small river based on the flow rate calculated by the flow rate calculation unit 7100. In step 215 (S215), the economic feasibility determination unit 712 determines whether the economic feasibility of the hydroelectric power plant utilizing a small river meets or exceeds a standard, based on the construction cost estimated by the construction cost estimation unit 704, the power transmission cost calculated by the power transmission cost calculation unit 706, and the power generation amount predicted by the power generation amount prediction unit 710.

[0028] FIG. 6 is a flowchart showing the process (S30) for determining the sustainability of a hydroelectric power plant according to this embodiment. 6, in step 300 (S300), the river width observation unit 7140 observes the change in the measured river width over one year. The flow rate stability evaluation unit 714 evaluates the stability of the river flow rate based on the change in the river width observed by the river width observation unit 7140. In step 305 (S305), the power demand prediction unit 716 predicts the amount of power demand in the power demand area based on the type and size of the facility in the power demand area. In step 310 (S310), the sustainability determination unit 718 determines the sustainability of the hydroelectric power plant based on the stability of the flow rate of the small river evaluated by the flow rate stability evaluation unit 714 and the medium to long-term demand forecast value of the demand electricity amount predicted by the demand electricity forecasting unit 716.

[0029] As described above, according to this embodiment, small rivers are extracted, and a small river to be used for hydroelectric power generation and a suitable site for constructing a hydroelectric power plant are determined based on the economic efficiency and sustainability of a hydroelectric power plant using the extracted small river. Since the hydroelectric power plant of this embodiment is a micro hydroelectric power plant that uses a small river, the stability of the flow rate of the small river greatly affects the amount of power generated. However, since the hydroelectric power plant development system 1 determines a suitable site after evaluating the stability of the flow rate of the small river in advance, a stable amount of power generation can be expected. In addition, the hydroelectric power plant development system 1 calculates the construction cost, operation cost, and power generation based on multiple factors and judges the economic efficiency of the hydroelectric power plant more strictly, it is possible to detect a small river suitable for small-scale hydroelectric power generation and a construction site for the hydroelectric power plant. In addition, the hydroelectric power plant development system 1 can observe the changes in river width over a certain period of time using the river width observation unit 7140 and estimate fluctuations in flow rate, making it possible for the equipment selection unit 722 to select a turbine in response to fluctuations in flow rate over a certain period of time in addition to the power generation predicted by the power generation prediction unit 710.

[0030] [Variations] In the above embodiment, the difficulty assessment unit 7042 evaluates the resistance of a hydroelectric power plant to natural disasters such as landslides and earthquakes based on the topography and geology, but in addition to this, for example, the difficulty assessment unit 7042 may also evaluate the degree of impact that the development of the hydroelectric power plant will have on the surrounding natural environment.
