Description

Dam-gun flood control system and linkage operation system {A COORDINATED OPERATION SYSTEM AND METHOD FOR FLOOD CONTROL IN MULTI-RESERVOIRS}

The present invention relates to a dam group flood control linkage operation system and a linkage operation method, in particular, by measuring the natural phenomena such as rainfall and water level in the basin and linking and operating the dam group based on this, to control the flood volume and to perform the flood analysis training according to the simulation training scenario. The present invention relates to a dam-based flood control linkage operation system and linkage operation method for improving flood analysis ability of flood analysts.

In general, a number of dams are installed and operated in the watershed, which can be used as a source of hydropower, water supply, industrial water, or irrigation by blocking rivers and storing water, or for the purpose of flood control, everywhere, etc. do. These dams are installed and operated separately in each basin. In terms of completion of using the water stored in the operation of the dams, the dams are well connected and operated in a relatively systematic manner.

 On the other hand, these dams are operated mainly for flood control for the individual safety of individual dams because the linked operation is not formalized in terms of flood control. That is, since dams in the watershed discharge water in order to focus on the safety of each dam without considering each other's flood inflow and discharge situation, when the discharge occurs, the river in the downstream metropolitan area lacks water supply capacity, causing bottlenecks. There was a problem.

In particular, in recent years, the flooding of dams and downstream streams is gradually increasing due to extreme weather due to global warming, and the situation of water management is worsening, such as the situation that exceeds the planned flooding amount at the time of dam design in the past.

Considering this situation, it is required to further secure water resources such as new dam construction, and to maximize the stability and efficiency of flood control of existing dams. In other words, non-structural measures are needed to more effectively control the amount of flooding by operating flood control and water supply dams formed up and down the watershed. Conventional dams are difficult to interconnect and operate, resulting in poor flood control capability. There was this.

In addition, the operation data of these dams are accumulated as a result and later used for dam operation. These results are simply accumulated in one-dimensional data, and thus are not linked to other information related to flood control, for example, satellite image information. There was a problem that multi-dimensional flood analysis was difficult because three-dimensional monitoring was impossible.

On the other hand, since such flood occurrences occur as fragmentary events throughout the year, it is difficult for the flood analysts to continuously acquire the flood analysis technology, and since the preliminary flood preparation has been made through formal training, a lot of time and effort is required to secure flood analysis experts. It was taking a while.

The present invention has been proposed to solve the above-mentioned problems of the prior art, and an object of the present invention is to control the flood amount by connecting and operating dam groups in the basin, and to monitor the flood amount effectively by visualizing and monitoring the floodable predicted area in three dimensions. It is to provide a dam flood control linkage operation system and linkage operation method that can be controlled.

The discharge amount of the upstream dams is calculated according to the margin amount, and when the flood control margin of the calculated control point is distributed to the upstream dams, the dam having insufficient storage capacity in consideration of the storage capability of the upstream dams at the time of flood control is considered. It is desirable to allocate the flood control margin first.

Hereinafter, a process in which dams in the watershed are linked and operated by the dam group linked operation server 300 having the above configuration will be described.

5 is a flowchart illustrating a process of determining the discharge amount of the dams in the watershed by the dam group linked operation server according to an embodiment of the present invention.

Step S110: First, when rainfall occurs, the remote terminal device 20 installed in each dam and river in the basin measures rainfall occurrence information such as rainfall and dam level of the dam and the river, and operates the dam group through the satellite 50. To the system 10. The dam group linked operation system 10 stores the rainfall occurrence information transmitted from the remote terminal device 20 through the data collection server 100 and transmits it to the data conversion server 200 at the same time keeping the collected data database 150. The data conversion server 200 converts the rainfall generation information into data necessary for dam group linkage operation and stores it in the flood information database 250. In addition, the five-day numerical rainfall forecast data produced by a separate rainfall prediction system (supercomputer) is automatically stored in the flood information database 250 after comprehensive review by the weather forecaster. On the other hand, the rainfall generation and prediction information converted by the data conversion server 200 is input to the dam group linkage operation server 300 is used as information for the linkage operation for each dam.

Step S120: when the rainfall generation and prediction information is input to the dam group linked operation server 300, the dam group discharge amount calculation module 341 provided in the dam group linked operation unit 340 of the dam group linked operation server 300 according to the rainfall occurrence information The volume of inflow flowing into each dam is determined, and accordingly, the discharge volume of each dam is determined to stably operate the dams. In order for the dams to operate stably, the water level of the dams must maintain the target reservoir, so the volume of water that the dams must discharge is the volume obtained by subtracting the target reservoir from the maximum reservoir when the dams do not discharge.

Step S130: On the other hand, if the dams discharge the determined discharge volume at once without considering the dams or the rivers located downstream, bottlenecks in which the water flows in the downstream dams or the rivers occur at once. Therefore, in the present invention, when the dams are discharged, a dam or a river located downstream is selected as a flood generation reference control point, and the discharge volume of the dams is distributed according to time so as not to cause a flood in the control point. At this time, the control point located in the direct downstream of the dam to be discharged preferentially is selected, and if it is necessary to discharge simultaneously at the upstream dams of different tributaries, the control point in the downstream where different streams are joined Perform the procedure of automatic selection.

Step S140: When a flood generation reference control point located downstream of the rainfall generating dams is selected, the flood control constraint flow rate of the control point is set, and the flood control constraint flow rate of the control point is based on the past flood control performance or river maintenance basic of the location. The plan will be set to reflect the embankment design constraints on the design flood. In addition, the flood analyst can manually correct the standard constraint flow rate according to the actual situation to allow effective linked operation.

Step S150: When the constraint flow rate of the control point is set, the flood control margin of the control point is calculated. In the embodiment of the present invention, the flow control margin of the control point is the natural flow rate flowing out of the remaining basin other than the dam basin under the assumption that the flood controllable dams located upstream of the control point store the entire flood in the dam without regulating discharge The value is calculated by subtracting the control point constraint flow rate. This is a space where flood can be communicated with ease at the reference control point, which considers the situation where the flood can be controlled without significant damage when discharged according to the discharge priority condition of the upstream dam.

Step S160: When the flood control margin of the control point is calculated, the flood control margin is allocated to each of the flood control dams located upstream. That is, the flood control margin of the control point is allocated to each of the upstream dams. In the embodiment of the present invention, the equivalent reservoir concept considering the storage capacity of the upstream dams at the time of flood control is applied to the dams having insufficient storage capacity. First, the flood control margin will be allocated. In addition, a larger amount of flood control margin is allocated to the larger discharge volume of the upstream dams.

Step S170: When the flood control margins are allocated to each of the flood control dams located upstream of the control point, the amount of timely discharge is calculated by reflecting its own flood control plan to the flood control margin allocated to each dam. In the embodiment of the present invention, when the flood control margin is allocated to each of the dams, the hydrological and hourly water gates and the water in consideration of the design and operation specifications of the dam, such as the flood control rate, water level discharge capacity, initial hydrological discharge start flow and low water level, etc. Estimate the generation discharge, and at this point, in order to minimize the peak flow at the downstream control point, the optimal flood control plan is determined by iterative calculation to calculate the discharge by hour. Figure 6 shows an example of the dam discharge distribution screen distributed by each dam through the dam group discharge amount calculation module according to an embodiment of the present invention.

Step S200: When the discharge amount of each dam for flood control is calculated by the dam group discharge amount calculation module 341 provided in the dam group linked operation unit 340 of the dam group linked operation server 300, the flood flood visualization module ( 342 performs a simulation according to the hourly discharge amount of each dam calculated by the dam group discharge amount calculation module 341. 7 illustrates an example of a dam discharge simulation result screen performed through the flood flood visualization module according to an embodiment of the present invention. As illustrated in FIG. 7, the flooding visualization module 342 simulates a level rise of the downstream river in the basin due to the discharge of each dam according to the hourly discharge amount of each dam calculated through the dam group discharge amount calculation module 341. The simulation process and results are visualized and expressed as if the flood situation is monitored in the field by projecting the watershed stream in three dimensions on the satellite image.

Step S210: Simulation is performed according to the discharge of each dam through the above process, and if there is a risk of flooding or if the rainfall and weather conditions change, it is necessary to recalculate the discharge amount of each dam. It may be repeated.

Step S300: On the other hand, when the discharge amount is calculated for each dam through the above process and the simulation is performed, the decision support module 343 provides information related to the dam discharge so that the flood analyst can finally perform the dam discharge decision. Done. 8 illustrates an example of dam discharge-related information screen provided through a decision support module according to an embodiment of the present invention. As shown in FIG. 8, the information related to dam discharge provided by the decision support module 343 is information on an inundable area where flooding occurred due to a conventional flood in the watershed. Once the simulation results and flood information related to dam discharge have been confirmed, the flood analyst finally makes dam discharge decisions.

Through the above process, the hourly discharges of the dams in the watershed are calculated and linked with each other, and the dam discharge simulation is performed according to the estimated discharge amount of the dams, and the flood analyst is provided with information on the flooded areas in the watershed. The discharge of my dams will be determined.

When the final discharge of the dams is determined through the decision support module 343, the determined discharge information of each dam is transmitted to the hydrologic control device of each dam through the satellite 50, and thus the hydrological control device of each dam is determined by the determined time. The discharge is controlled by controlling the flood gate according to the discharge amount.

 On the other hand, since flooding generally occurs as an event during a certain period of the year, it is difficult for the flood analysts to continuously acquire the flood analysis technique. The dam group linkage operation unit 340 of the dam group linkage operation server 300 according to the present invention is used. The provided flood analysis training module 344 allows flood analysts to continuously learn flood analysis techniques.

The flood analysis training module 344 allows the manager and the flood analysis trainer to generate a simulation training scenario through a GUI environment and to execute the training according to the generated simulation training scenario. FIG. 10 illustrates an embodiment of the present invention. An example of the simulation training screen displayed on the screen through the flood analysis training module is shown.
