Description

Technical Field

[0001] The present invention relates to the technical field of engineering simulation and numerical simulation, and in particular to a method, device and electronic equipment for calculating the total storage capacity and dispatchable storage capacity of a reservoir. Background Art

[0002] With the development of social economy, the functions of large reservoirs in flood control, water supply, agricultural irrigation, people's livelihood, ecological environment, etc. are becoming more and more prominent, playing an important role in my country's social and economic development. The new situation requires improving the refinement level of the reservoir dispatching process. Among them, the calculation of reservoir capacity is crucial and directly affects the formulation of reservoir dispatching plans. The commonly used reservoir capacity calculation methods can be divided into static capacity methods and dynamic capacity methods based on cross-sections and water surface lines. Due to the long reservoir area, the backwater water surface line has a significant slope due to the flow of water, and the water level at the tail of the reservoir is much higher than the water level in front of the dam. Therefore, the reservoir capacity cannot be calculated according to the static backwater curve, and a dynamic capacity method that reflects the change of the water surface line must be used.

[0003] However, due to the sedimentation carried by the incoming water, the cross-sectional shape of the river channel is constantly changing, and the vast reservoir area makes it impossible to measure the cross-sectional shape of the river channel month by month and year by year. Under the action of sediment accumulation, the dynamic storage capacity method based on the cross-section and water surface line inevitably does not conform to the actual storage capacity. Therefore, reservoir dispatching often finds that the storage capacity calculated by existing technology deviates from the actual situation.

[0004] Therefore, there is a problem in the prior art that the calculated reservoir capacity does not match the actual capacity and cannot meet the reservoir scheduling needs. Summary of the invention

The specific process may include: first, the current storage capacity of each river section is calculated based on the supplementary storage capacity and the theoretical storage capacity, then the total storage capacity of the current reservoir is calculated based on the current storage capacity of each river section, and finally the total storage capacity of the current reservoir and the latest storage capacity Q are calculated. 总 and the total replenishment capacity Q 总补 , calculate the dispatchable storage capacity Q of the reservoir 可 The total storage capacity and the dispatchable storage capacity Q of the current reservoir are 可 Report to the reservoir dispatching department for dispatching personnel to determine the total storage capacity and dispatchable storage capacity of the reservoir.

Through the above method, firstly, according to the measured water level of each river section, the corresponding supplementary storage capacity and the total supplementary storage capacity of the reservoir area are selected from the database; then the precise water level is solved according to the supplementary storage capacity; secondly, the theoretical storage capacity is obtained according to the precise water level; finally, according to the supplementary storage capacity, the theoretical storage capacity, the latest storage capacity and the total supplementary storage capacity, the total storage capacity and the dispatchable storage capacity of the reservoir are calculated. According to the real-time measured water level of each river section, combined with the database, the total storage capacity and dispatchable storage capacity of the reservoir can be quickly calculated, avoiding frequent section monitoring and providing timely and reliable total storage capacity and dispatchable storage capacity of the reservoir. This solves the problem in related technologies that the calculated reservoir capacity does not match the actual capacity and cannot meet the reservoir dispatching needs.

[0068] As an optional embodiment, before obtaining the latest storage capacity of the reservoir at the current moment, the measured water level of each river section, and the river section parameters, the method further includes:

[0069] Obtain the normal water level of the reservoir, flood control limit water level and reservoir area parameters;

[0070] According to the preset hydrodynamic equation, normal water level, flood control limit water level and reservoir parameters, the first water level corresponding to each position in the reservoir area when the water level in front of the dam is the flood control limit water level and the second water level corresponding to each position in the reservoir area when the water level in front of the dam is the normal water level are obtained;

[0071] The reservoir area is divided into multiple areas according to the normal water storage level, flood control limit water level, first water level and second water level;

[0072] Divide each area into multiple river segments.

[0073] Optionally, obtain the topographic and hydrological information of the reservoir, especially the latest topographic cross-section measurement data at the current moment, as well as the reservoir's basin overview, flood conditions, net inflow, reservoir water level change patterns, etc., to determine the normal water storage level Z of the reservoir. 蓄 and flood control limit water level Z 限 Based on the above information, the reservoir parameters of the reservoir area are determined, including: the water surface width of the reservoir area, the lateral inflow flow, the average flow velocity of the cross section, the roughness value of the river channel, the hydraulic radius, etc.

[0074] A preset hydrodynamic equation model of the reservoir is established, wherein the preset hydrodynamic equation may be a one-dimensional hydrodynamic equation, including a water flow continuity equation and a water flow motion equation. The water flow continuity equation is shown in formula (1), and the water flow motion equation is shown in formula (2):

[0075]

[0076]

[0077] Among them, t represents time, x represents space, B represents water surface width, Z represents water level, Q represents flow rate, and q represents water volume. L is the lateral inflow flow on this river section, u is the average flow velocity of the section, g is the gravitational acceleration, A is the cross-sectional area of ​​the water flow, n is the roughness value of the river channel, and R is the hydraulic radius.

[0078] The water level in front of the dam is set as the flood control limit water level Z 限 As the first boundary condition, the finite difference method is used to solve the preset hydrodynamic equation according to the above reservoir parameters, and the water level in front of the dam at any spatial position x in the reservoir is Z. 限 The first water level Z x限 .

[0079] The water level in front of the dam is set to the normal water storage level Z 蓄 As the second boundary condition, the finite difference method is used to solve the preset hydrodynamic equation according to the above reservoir parameters, and the water level in front of the dam at any position x in the reservoir space is Z. 蓄 The second water level Z x蓄 .

[0080] According to the normal water level Z 蓄 , Flood control limit water level Z 限 , first water level Z x限 And the second water level Z x蓄 , the reservoir area is divided into multiple regions, and each region is divided into multiple river sections. Each river section is only in a certain region and will not cross two regions. Finally, N river sections are obtained, where N is a positive integer and there is no specific number limit here.

[0081] In the embodiment of the present application, the preset hydrodynamic equation is solved by the finite difference method to obtain the first water level and the second water level corresponding to the reservoir area when the water level in front of the dam is the flood control limit water level and the normal water storage level, respectively, and the reservoir area is divided into multiple river sections according to the first water level and the second water level. It is convenient to subsequently establish a database containing the supplementary storage capacity under different water level conditions of each river section, so that the present application can quickly calculate the total storage capacity and dispatchable storage capacity of the current reservoir according to the real-time measured water level of the river section.

[0082] As an optional embodiment, before obtaining the supplementary storage capacity of each river section and the total supplementary storage capacity of the reservoir area from the database, the method further includes:

[0083] Obtain topographic cross-section data and water level and flow data for each river section;

[0091] According to the terrain section data and water level and flow data, the supplementary storage capacity corresponding to each river section under each water level layer is inverted. Specifically, the supplementary storage capacity corresponding to each river section under different water levels (each water level layer) is inverted offline using the latest water level and flow data measured by the most recent terrain section data of each river section. For example, the supplementary storage capacity of the i-th river section is Q i修 , i is a positive integer less than or equal to the total number of river sections. At the same time, according to the above supplementary storage capacity, the water level in front of the dam is calculated to be the normal water level Z 蓄 When the total replenishment capacity of the reservoir area is Q 总补 , where Q 总补 =∑Q i修 .

[0092] A database is established based on the supplementary storage capacity and the total supplementary storage capacity.

[0093] In the embodiment of the present application, the reservoir area is divided into multiple river sections, and the hydrodynamic process of each river section is fully trained offline, so as to establish a database containing the supplementary storage capacity under different water level conditions of each river section and the total supplementary storage capacity of the reservoir area. By making full use of historical data and calculating the supplementary storage capacity of the reservoir through a large number of offline hydrodynamic model substitution training, the present application can avoid frequent section monitoring and provide timely and reliable total storage capacity and dispatchable storage capacity of the reservoir.

[0096] Determine the first critical value and the second critical value according to the normal water storage level and the flood control limit water level;

[0097] Merge all positions corresponding to water level change values ​​that are less than the first critical value to obtain a first area;

[0098] Merge all positions corresponding to water level change values ​​greater than the second critical value to obtain a second area;

[0099] The other areas in the reservoir area outside the first area and the second area are regarded as the third area.

[0100] Optionally, the first water level Z corresponding to any spatial position x in the reservoir area is used. x限 Subtract the second water level Z x蓄 , calculate the water level change value Zs, where Zs = Z x蓄 -Z x警 .

[0101] According to the normal water level Z 蓄 and flood control limit water level Z 限 , determine the first critical value and the second critical value, wherein the first critical value can be 1.15×(Z 蓄 -Z 限 ), the second critical value can be 1.35×(Z 蓄 -Z 限 ).

[0102] If the water level change value is less than the first critical value, the position corresponding to the water level change value belongs to the first area, for example: water level change value Zs<1.15×(Z 蓄 -Z 限 ), then the location belongs to the first area, and by merging all the locations belonging to the first area, we get the first area, which can be a lake area.

[0103] If the water level change value is greater than the second critical value, the position corresponding to the water level change value belongs to the second area, for example: water level change value Zs>1.35×(Z 蓄 -Z 限 ), then the position belongs to the second area, and all the positions belonging to the second area are merged to obtain the second area, which can be the river area.

[0104] The other areas in the storage area other than the first area and the second area are regarded as the third area, and the third area can be a variable area.

[0109]

[0110]

[0111] where n i is the roughness coefficient of the i-th river reach, and Q i修 is the corrected supplementary storage capacity of the i-th river reach.

[0112] In the embodiment of the present application, the control equation for each river reach is established, so that the present application can quickly calculate the accurate water level of each river reach according to the supplementary storage capacity of each river reach.

[0115] Updating the database according to the updated topographic cross-section data and updated water level-discharge data.

[0116] Optionally, due to the scouring and silting process of reservoir sediment, the storage capacity of the reservoir is in dynamic change. Therefore, whenever there is corresponding latest water level-discharge data, it is necessary to update the supplementary storage capacity of each river reach and the total supplementary storage capacity of the reservoir area in the database in a timely manner. The update process includes: updating the topographic cross-section data and water level-discharge data of each river reach according to the latest water level-discharge data to obtain updated topographic cross-section data and updated water level-discharge data.

[0120] According to the current storage capacity, the total storage capacity of the reservoir is obtained;

[0121] Based on the latest storage capacity, total replenishment capacity and current storage capacity, the dispatchable storage capacity of the reservoir is obtained.

[0122] Optionally, taking the i-th river section as an example, the replenishment capacity Q i修 and theoretical storage capacity Q i理 Add together to get the current reservoir capacity Q of the i-th river section i , where Q i =Q i修 +Q i理 Repeat the above process to calculate the current storage capacity of each river section.
