Description

Technical Field

[0001] The present invention relates to the technical field of data prediction, and in particular, to a method, system, and computer-readable medium for predicting the power generation of a small hydropower plant.

Background Art

[0002] A small hydropower plant is a small hydropower plant with a small installed capacity that generates electricity depending on water resources, and its power generation is affected by rainfall. If there is rainfall in the upstream basin of the small hydropower plant, the rainwater converges into the river where the small hydropower plant is located and becomes the power generation source of the small hydropower plant. Since it takes time for the rainwater to converge, there is a lag in the impact of rainfall on the power generation of the small hydropower plant, that is, the rainfall lags behind the power generation of the small hydropower plant. There are several aspects to the lag effect of rainfall on the power generation of small hydropower plants, but one of the main aspects is the total rainfall. The greater the total rainfall, the higher the power generation of the small hydropower plant. Existing power generation prediction models for small hydropower plants predict the power generation of the small hydropower plant based on the total rainfall and the past power generation of the small hydropower plant. However, there are multiple aspects of rainfall that affect the lag of the generated power of small hydropower plants. In this prior art, only one of the main aspects of the above effects is considered, lacking comprehensiveness and having a problem of low prediction accuracy.

Embodiments for Carrying Out the Invention

[0005] Hereinafter, the present invention will be described in more detail with reference to specific embodiments. As aspects of the influence of rainfall on the delay of the generated power of a small hydropower plant, there are the total rainfall amount, the rainfall amount stored in the dam lake, the rainfall scheduling amount, the upstream basin topography of the small hydropower plant, and the distance from the rainfall position to the small hydropower plant. The total rainfall amount has a positive correlation with the power generation amount of the small hydropower plant, that is, the larger the total rainfall amount, the higher the power generation amount of the small hydropower plant. Since rainwater accumulates in the dam lake and there is a possibility that the rainwater is discharged into the reservoir where the small hydropower plant is located, by subtracting the amount of rainwater stored in the dam lake from the amount of rainwater discharged, the total power generation amount of the small hydropower plant can be calculated. ​​​​​​​It emits. The terrain of the upper reaches of a small hydropower plant affects the time required for rainfall to converge to the location of the small hydropower plant. When the terrain is relatively flat, the rainfall convergence time is slightly shorter. When the terrain has a steep gradient and a large elevation difference, the rainfall convergence time is slightly longer. The distance of rainfall to the location of the small hydropower plant also affects the rainfall convergence time, and the distance and the rainfall convergence time are proportional to the distance, that is, the shorter the distance, the shorter the convergence time.

It is used to predict the power generation of a small hydropower plant where the field terrain is flat and steep. These three terrain prediction modules each pre-store a prediction days threshold, and the first day of the prediction days threshold is counted from the prediction day. For example, if the prediction days threshold is set to 10, the terrain prediction module predicts the power generation of the small hydropower plant for each day from the first day to the tenth day of the prediction day. The method for predicting the power generation of a small hydropower plant includes an input information step and a prediction step, and the specific steps will be described in detail below. In the information input step, data is manually input into the terminal device. When there is rainfall in the upstream basin of the small hydropower plant and there is dam lake stored rainfall in the upstream basin of the small hydropower plant, the terminal device needs to manually input a plurality of data such as the small hydropower plant ID code, total rainfall, rainfall location, lag days, and dam lake stored rainfall. Based on this dam lake stored rainfall, when rainfall scheduling for the reservoir where the small hydropower plant is located is performed within the lag days period, the terminal device needs to manually input a plurality of data such as the small hydropower plant ID code, total rainfall, rainfall location, lag days, dam lake stored rainfall, and rainfall scheduling quantity. When there is rainfall in the upstream basin of the small hydropower plant but there is no dam lake stored rainfall and no water resource scheduling for the small hydropower plant, etc., the terminal device needs to manually input a plurality of data such as the small hydropower plant ID code, total rainfall, rainfall location, and lag days. When there was no rainfall in the upstream basin of the small hydropower plant on the day before the prediction, only the data of the small hydropower plant ID code needs to be manually input into the terminal device as well. The prediction step is as shown in Figure 1. A computer program executable on the computer-readable pre-storage medium is pre-stored, and the processor runs the computer program as follows. When there is rainfall in the upstream basin of the small hydropower plant but there is no dam lake stored rainfall and no water resource scheduling for the small hydropower plant, etc., the terminal device needs to manually input a plurality of data such as the small hydropower plant ID code, total rainfall, rainfall location, and lag days. When there was no rainfall in the upstream basin of the small hydropower plant on the day before the prediction, only the data of the small hydropower plant ID code needs to be manually input into the terminal device as well. When there is no rainfall in the upstream basin of the small hydropower plant on the day before the prediction, only the data of the small hydropower plant ID code needs to be manually input into the terminal device is sufficient. The prediction step is as shown in Figure 1. A computer program executable on the computer-readable pre-storage medium is pre-stored, and the processor runs the computer program stored therein. By executing this, the prediction step shown in FIG. 1 is realized. The power generation prediction system for the small hydropower plant executes this prediction step based on this, specifically as follows. When the information processing module receives a plurality of data such as the small hydropower plant ID code, total rainfall, rainfall position, and number of delay days, the power generation prediction system of the small hydropower plant executes step A, and step A includes the following steps: Step a1. The information processing module calculates the difference between the rainfall position and the small hydropower plant position based on the rainfall position and the small hydropower plant position information previously stored in the information module of the small hydropower plant, and obtains the distance from the rainfall position to the small hydropower plant. Step a2. The prediction module activates the terrain prediction module corresponding to the upstream basin terrain of the small hydropower plant based on the terrain information of the upstream basin of the small hydropower plant previously stored in the information module of the small hydropower plant. The terrain prediction module is based on the terrain information of the upstream basin of the small hydropower plant, total rainfall, number of delay days, obtained distance, and the power generation data of the monthly historical power generation of the small hydropower plant previously stored in the information module of the small hydropower plant, and predicts the power generation of the small hydropower plant on each day during the number of delay days. Step A is explained by way of example: The upstream basin terrain of the small hydropower plant N01 previously stored in the information module of the small hydropower plant is flat terrain, and the power generation data P of the monthly historical power generation of the small hydropower plant N01 =(100kW, 500kW, 1000kW, 600kW, 500kW 歴史1 =(100kW, 500kW, 1000kW, 600kW, 500kW , 400kW, 400kW…200kW, 700kW, 400kW), the position of the small hydropower plant N0 1 is S01, and the small hydropower plant N ​​​The upstream basin topography of No. 02 is steep terrain, and the monthly historical power generation data of the small hydropower plant N02 P 歴史2 =(400kW, 550kW, 600kW, 650kW, 850kW, 1000 kW, 1200kW…800kW, 1000kW, 1500kW), the location of the small hydropower plant N02 is S02, and the monthly historical power generation data P of the small hydropower plant N0 3 stored in advance in the information module of the small hydropower plant. The upstream basin topography of the small hydropower plant N03 is flat and steep terrain, and the monthly historical power generation data of the small hydropower plant N03 -ta P 歴史3 =(1000kW, 900kW, 800kW, 600kW, 600kW, 5 50kW, 400kW…650kW, 400kW, 400kW), and the location of the small hydropower plant N 03 is S03. Based on this assumption, the following example is shown.

[0006] (1) Assume that the small hydropower plant ID code received by the information processing module is N01, the total rainfall is 10000 m3, the rainfall location is S1, and the delay days are 10. In this case , based on the rainfall location S1 and the information of the location S01 of the small hydropower plant N01 stored in advance in the information module of the small hydropower plant, the information processing module calculates the difference between the rainfall location S1 and the small hydropower plant location S01. Assuming that the difference is 100 and the unit is km, the distance from the rainfall location to the small hydropower plant is 100 km. The prediction module starts the flat terrain prediction module based on the information that the upstream basin topography of the small hydropower plant N01 stored in advance in the information module of the small hydropower plant is flat terrain. The flat terrain prediction module uses the flat terrain information, total rainfall of 10000 m3, delay days of 10, the obtained distance of 100 km, and the monthly historical power generation data P of the small hydropower plant N01 stored in advance in the information module of the small hydropower plant to predict. Based on the information that the upstream basin topography of the small hydropower plant N01 stored in advance in the information module of the small hydropower plant is flat terrain, the flat terrain prediction module is activated. The flat terrain prediction module uses the flat terrain information, total rainfall of 10000 m3, delay days of 10, the obtained distance of 100 km, and the monthly historical power generation data P of the small hydropower plant N01 stored in advance in the information module of the small hydropower plant to predict. 歴史1 =(100kW, 500kW, 1000kW, 600kW, 500kW, 400k W, 400kW…200kW, 700kW, 400kW) based on this, small hydropower plant N0 1's daily power generation P for each day from the 1st day to the 10th day of the prediction date 予測A1 is 300 kW, 1000kW, 1600kW, 1900kW, 1700kW, 1500kW, 10 00kW, 800kW, 600kW, 500kW and it is predicted that there is a possibility that it is so. (2) When the small hydropower plant ID code received by the information processing module is N02, the total rainfall is 10000 m3, the rainfall location is S2, and the number of delay days is 5. The information processing mod ule calculates the difference between the rainfall location S2 and the small hydropower plant location S02 based on the information of the rainfall location S2 and the small hydropower plant stored in advance in the information module of the small hydropower plant N02 location S02 information. Assuming that the difference is 100 and the unit is km, the distance from the rainfall location to the small hydropower plant is 100 km. The prediction module starts the steep terrain prediction module based on the information that the upstream basin terrain of the small hydropower plant N02 stored in advance in the information module of the small hydropower plant is steep terrain. The steep terrain prediction module uses the steep terrain information, total rainfall 1 0000 m3, number of delay days 5, the obtained distance 100 km and the power generation data P of the monthly historical power generation of the small hydropower plant N02 stored in advance in the information module of the small hydropower plant Based on P=(400 kW, 550kW, 600kW, 650kW, 850kW, 1000kW, 1200kW 歴史2 =(400 kW, 550kW, 600kW, 650kW, 850kW, 1000kW, 1200kW …800kW, 1000kW, 1500kW), for the small hydropower plant N02, the daily power generation P for each day from the 1st day to the 5th day 予測A2 is 1600kW, 2100kW, 20 Predict that it may be 00 kW, 1900 kW, or 1900 kW. (3) When the small hydropower plant ID code received by the information processing module is N03, the total rainfall is 10000 m3, the rainfall location is S3, and the number of delay days is 3, the information processing mo dule calculates the difference between the rainfall location S3 and the small hydropower plant location S03 based on the information of the small hydropower plant N02 location S03 stored in advance in the information module of the small hydropower plant. If it is assumed that the difference is 50 and the unit is km, the distance from the rainfall location to the small hydropower plant is 50 km. The prediction module starts the flat-steep terrain prediction module based on the information that the upstream basin terrain of the small hydropower plant N03 stored in advance in the information module of the small hydropower plant is flat-steep terrain. The flat-steep terrain prediction module uses the flat-steep terrain information, total rainfall of 10000 m3, number of delay days of 3, the obtained distance of 100 km, and the monthly historical power generation data P =(1000 kW, 900 kW, 800 kW, 600 kW, 600 kW, 550 kW 歴 史3 =(1000 kW, 900 kW, 800 kW, 600 kW, 600 kW, 550 kW 予測A3 Based on this, when the information processing module further receives the dam lake storage rainfall data, and in particular when the information processing module receives multiple data such as the small hydropower plant ID code, total rainfall, rainfall location, number of delay days, and dam lake storage rainfall, the power generation prediction system of the small hydropower plant executes step B, and step B includes the following steps.​​ Step b1. Based on the rainfall position and the position information of the small hydropower plant pre-stored in the information processing module, the information processing module calculates the difference between the rainfall position and the small hydropower plant position based on the pre-stored position information of the small hydropower plant, to obtain the distance from the rainfall position to the small hydropower plant. Step b2. Based on the total rainfall and the dam lake storage rainfall, the information processing module calculates the difference between the total rainfall and the dam lake storage rainfall to obtain the actual power generation rainfall used by the small hydropower plant. Step b3. The prediction module activates the terrain prediction module corresponding to the upstream basin terrain of the small hydropower plant based on the terrain information of the upstream basin of the small hydropower plant pre-stored in the information module of the small hydropower plant. The terrain prediction module predicts the power generation amount of the small hydropower generation for each day during the lag days based on the terrain information of the upstream basin of the small hydropower plant, the lag days, the obtained distance, the obtained power generation rainfall, and the power generation data of the monthly historical power generation of the small hydropower plant pre-stored in the information module of the small hydropower plant. An example is given to illustrate Step B: The upstream basin terrain of the small hydropower plant N01 pre-stored in the information module of the small hydropower plant is flat terrain, and the power generation data P of the monthly historical power generation of the small hydropower plant N01 = (100kW, 500kW, 1000kW, 600kW, 500kW 歴史1 =(100kW, 500kW, 1000kW, 600kW, 500kW , 400kW, 400kW…200kW, 700kW, 400kW), the position of the small hydropower plant N0 1 is S01, the upstream basin terrain of the small hydropower plant N 02 pre-stored in the information module of the small hydropower plant is steep terrain, and the power generation data of the monthly historical power generation of the small hydropower plant N02 P 歴史2 =(400kW, 550kW, 600kW, 650kW, 850kW, 1000 ​​​​​​​kW, 1200kW…800kW, 1000kW, 1500kW), Small Hydropower Plant N02 The location is S02, and Small Hydropower Plant N0 The upstream basin terrain of No. 3 is flat and steep terrain, and the monthly historical power generation data of Small Hydropower Plant N03 Table P 歴史3 =(1000kW, 900kW, 800kW, 600kW, 600kW, 55 0kW, 400kW…650kW, 400kW, 400kW), the location of Small Hydropower Plant N03 Assuming that the location is S03, based on this assumption, the following example is shown.

[0007] (1) The small hydropower plant ID code received by the information processing module is N01, the total rainfall is 10000 m3, the rainfall location is S1, the number of delay days is 10, and the dam lake storage rainfall is 1000 m3. In this case, the information processing module, based on the rainfall location S1 and the location S01 information of Small Hydropower Plant N01 pre-stored in the information module of the small hydropower plant, calculates the difference between the rainfall location S1 and the location S01 of the small hydropower plant. Assuming that the difference is 100 and the unit is km the distance from the rainfall location to the small hydropower plant is 100 km. Based on the total rainfall of 10000 m3 and the dam lake storage rainfall of 1000 m3, the difference between the total rainfall of 10000 m 3 and the dam lake storage rainfall of 1000 m3 is calculated, and the actual power generation rainfall used for the small hydropower plant is 9000 m3.
