The present invention relates to a method and apparatus for calculating the economic effect according to the artificial rainfall experiment in the dam basin.

The oceans make up about 70% of the Earth, but only about 9% of the evaporation of water vapor generated from the sea surface moves to land. About 97% of the total amount of water moving to land is salt water and the rest is fresh water, but only 0.3% of fresh water is actually usable by humans. Humans have used this freshwater in various fields such as agriculture, industry, and commerce, but as the use of water continues to increase with the increase in population, various methods for securing water resources are being developed.

The display unit 130 may be combined with the input unit 120 to be implemented as a touch screen.

The memory 140 stores operation programs of the electronic device 100 . Also, the memory 140 may store information on a target dam capable of performing an artificial rainfall experiment. In this case, the information on the target dam may include information such as the name of the dam, a location including latitude and longitude, a watershed area, and a lightning strike. Also, the memory 140 stores a plurality of boundary values set by the controller 150 .

The control unit 150 detects effective clouds based on the satellite data called to calculate the economic effect of the artificial rainfall experiment in the dam basin, and calculates the amount of water resources based on the experimental conditions related to the artificial rainfall experiment. And the control unit 150 calculates the economic effect according to the artificial rainfall experiment in the dam basin corresponding to the experimental conditions based on the amount of water resources and displays it on the display unit 130 .

More specifically, the control unit 150 receives a target dam for estimating the economic effect from the input unit 120 after a calculation signal for calculating the economic effect according to the artificial rainfall experiment in the dam basin is received from the input unit 120 . get input In addition, the control unit 150 checks the input location including the latitude and longitude of the target dam. The control unit 150 calls the satellite data for the confirmed position, but calls the satellite data of the critical year based on the time point at which the artificial rainfall experiment is to be performed.

The satellite data may include at least one of satellite cloudiness, cloud top altitude, cloud cover, and rainfall intensity. The satellite cloud fraction is a fraction of a corresponding grid region cloud detected by a satellite, and means a cloud amount (unit: %) from 0 to 100. Cloud top height means the height of the top of the cloud (unit: km). The cloud phase means a cloud state, that is, a water phase and an ice phase. The rainfall intensity (rainfall rate) means the intensity (unit: mm/h) of rainfall that can occur within the grid area.

The control unit 150 detects effective clouds based on the called satellite data, checks the occurrence frequency of effective clouds, and calculates the amount of water resources that can be obtained from the target dam based on the confirmed occurrence frequency of effective clouds. At this time, the effective cloud is a cloud with the condition that the amount of satellite cloud exceeds 80%, the cloud top altitude is 1 to 5 km, the cloud phase is liquid or ice, and the rainfall intensity is less than 5 mm/h. It means a cloud suitable for cloud seeding). To this end, the control unit 150 calculates the number of experiments using the frequency of occurrence of effective clouds, the number of days of occurrence of effective clouds, the time available for the artificial rainfall experiment, and the artificial rainfall experiment time, and calculates the number of experiments, the number of experiments, the amount of snow or rainfall, and the experiment success rate. and the effective area to calculate the amount of water resources.

In addition, if the target dam is a dam using hydroelectric power, the controller 150 calculates the amount of electricity produced in the target dam by calling a shock drop for the target dam. Electricity production is calculated using the amount of water resources, the electric shock fall, and the facility efficiency, and the control unit 150 calculates the final economic effect using the amount of water resources, the water sales price, the electricity production amount and the electricity sales price. Conversely, if the target dam is a dam that does not use hydroelectric power, the controller 150 calculates the final economic effect by using the amount of water resources and the water sales price.

2 is a flowchart for explaining a method of calculating the economic effect according to the artificial rainfall experiment in the dam basin according to an embodiment of the present invention.

Referring to FIG. 2 , in step 201 , the control unit 150 checks whether a calculation signal for calculating the economic effect is received through the input unit 120 . As a result of checking in step 201, if the calculation signal is received, the control unit 150 performs step 203. If the calculation signal is not received, the control unit 150 waits for the reception of the calculation signal.

In step 203, the control unit 150 calls the satellite data. More specifically, the control unit 150 checks the location including the latitude and longitude of the target dam for which the economic effect is calculated, that is, the target dam for which the artificial rainfall experiment is to be performed. The controller 150 may call the satellite data for the confirmed location, but call the satellite data of the critical year based on the time point at which the artificial rainfall experiment is to be performed. At this time, the satellite data refers to data acquired from geostationary satellites such as Chollian-1 (COMS) and Chollian-2 (GK-2A). For example, geostationary orbiting satellites such as the Chollian 2 satellite can generate satellite data by observing a specific terrestrial area with a spatial resolution of 2km*2km every 2 minutes.

In step 205, the control unit 150 detects effective clouds based on the satellite data called in step 203, checks the frequency of occurrence of effective clouds, and performs step 207. In this case, the method of the controller 150 detecting the effective luck and confirming the occurrence frequency of the effective luck will be described in more detail with reference to FIG. 3 below.

으로 설정한 경우 댐의 유역면적이 이를 초과하면 최대 유효면적이 300

으로 설정된다. 유효면적이 300

미만일 경우 유역면적이 유효면적으로 설정된다. 209단계에서 제어부(150)는 205단계에서 확인된 유효운의 발생빈도와 207단계에서 호출된 유역면적에 의해 산출된 유효면적을 이용하여 목표 댐에서 획득될 수 있는 수자원량을 산출한다. 보다 구체적으로, 제어부(150)는 하기의 수학식 1과 수학식 2를 이용하여 수자원량을 산출한다. In step 207, the control unit 150 calls the watershed area for the target dam. At this time, the watershed area is information necessary to calculate the effective area of snowfall or rainfall generated on the ground by the artificial rainfall experiment. For example, the effective area is 300

If set to , if the watershed area of the dam exceeds this, the maximum effective area will be 300.

is set to 300 effective area

If less than, the watershed area is set as the effective area. In step 209, the control unit 150 calculates the amount of water resources that can be obtained from the target dam using the effective area calculated by the frequency of occurrence of effective clouds checked in step 205 and the watershed area called in step 207. More specifically, the control unit 150 calculates the amount of water resources by using Equations 1 and 2 below.

In this case, the number of days means the number of days in a month when the effective luck occurrence frequency is an average monthly value, and means the number of days in a year when the effective luck occurrence frequency is an annual average value. In addition, in the case of an artificial rainfall experiment using a meteorological aircraft, the time means the time during which clouds can be visually identified. For example, the artificial rainfall experiment can be set to 10 hours because the experiment can be conducted only during the daytime (09:00 to 18:00), but the time may be changed according to the change of season. Experimental time refers to the time required to perform the precipitation precipitation experiment. That is, it can be set in consideration of the movement to the target area, the seeding time, and the turning time.

In this case, the snowfall or rainfall amount and the experimental success rate may be arbitrarily set. For example, the average snowfall or rainfall and the experimental success rate according to artificial rainfall experiments in developed countries including the Republic of Korea may be applied. The effective area can be set arbitrarily by the user as the effective area of precipitation generated by the artificial rainfall experiment, and can be set based on the watershed area of the target dam.

Next, in step 211, the control unit 150 checks whether the target dam is a dam using hydroelectric power. As a result of checking in step 211, if the target dam is a dam using hydroelectric power, the control unit 150 performs step 213, and if it is a dam that does not use hydroelectric power, the control unit 150 performs step 215. In step 213 , the control unit 150 calls a blitz fall for the target dam and performs step 215 . Next, in step 215, the control unit 150 calculates the economic effect by using the amount of water resources, the water sales price, the electricity production amount, and the electricity sales price. To this end, preferentially, the control unit 150 calculates the power production amount in the target dam using Equation 3 below.

In this case, the water resource amount is the water resource amount calculated in step 209, the electric shock fall is the electric shock fall in the target dam, and the facility efficiency is a constant that can be set arbitrarily.

Then, the control unit 150 calculates the final economic effect by using Equation 4 below, and displays the calculated economic effect on the display unit 130 by performing step 217 .

At this time, the amount of water resources is the amount of water resources calculated in step 209, and the sale price of water is a value that fluctuates from time to time according to the sale price of water announced by the Korea Water Resources Corporation. The amount of electricity produced is the value calculated in Equation 3, and the electricity sales price is a value that fluctuates from time to time according to the electricity transaction price announced to the Korea Electric Power Corporation.

Conversely, if it is confirmed in step 211 that the target dam is not a dam using hydroelectric power, the controller 150 performs step 215 . In step 215 , the control unit 150 calculates the final economic effect by using Equation 5 below and performs step 217 to display the economic effect calculated in step 215 on the display unit 130 .

3 is a detailed flowchart for explaining a method for detecting effective luck according to an embodiment of the present invention. In addition, effective clouds refer to clouds suitable for seeding, and can be detected from cloud characteristics and rainfall intensity data observed based on satellites. In other words, effective cloudiness is when the amount of cloud cover, which is the cloud characteristic data observed from geostationary satellites such as Chollian 2, exceeds 80%, the cloud top altitude is within 1 to 5 km, the cloud phase is liquid or ice, and the rainfall intensity is less than 5 mm/h. is defined as

Referring to FIG. 3 , in step 301 , the controller 150 preferentially sets a plurality of boundary values in order to detect effective luck. Setting the boundary value is to set the boundary value of the satellite cloud volume, cloud top altitude, cloud cover and rainfall intensity, and the user can set it arbitrarily. characterization may be considered. For example, when setting the boundary value, the control unit can set the effective flight altitude of the weather aircraft high in consideration of the topographical altitude when an artificial rainfall experiment is performed in an area higher than 800m above sea level, such as Daegwallyeong, and natural precipitation occurs frequently. It may increase or decrease the conditions for rainfall intensity in areas where it occurs or does not.

In step 303, the control unit 150 compares the satellite data with a plurality of boundary values set in order to detect effective clouds. As a result of the comparison in step 303, when the numerical values included in the satellite data converge to a plurality of boundary values, the control unit 150 performs step 305, and if any one of the plurality of boundary values does not converge, it is confirmed that no effective luck is detected to end the process. At this time, the control unit 150 detects effective clouds based on the satellite cloud volume, cloud top altitude, and rainfall intensity among the set boundary values, and is effective based on the effective clouds detected for a critical year based on the time at which the artificial rainfall experiment is to be performed. Calculate the frequency of occurrence of luck. In addition, the control unit 150 averages the frequency of occurrence of effective clouds in the vicinity of the reference grid for each satellite grid, for example, the frequency of occurrence of effective clouds in a radius of 200 km, and the frequency of occurrence of effective clouds in the target dam area can be calculated by pre-interpolating four neighboring grids. there is.

In step 305, if it is confirmed that effective luck has been detected based on the satellite data and a plurality of boundary values, the controller 150 returns to step 207 of FIG. For example, 80% of satellite cloudiness, 1km or more and 5km or less of cloud top altitude, and less than 5mm/h of rainfall intensity may be set as boundary values. After setting the boundary value in this way, the control unit 150 checks the satellite cloud volume, cloud top altitude, and rainfall intensity among the numerical values included in the satellite data, and the satellite cloud volume exceeds 80%, and the cloud top altitude is 1 km or more and 5 km or less, If the rainfall intensity is less than 5 mm/h, it can be confirmed that effective clouds are detected.
