[0053] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0054] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should be the usual meanings understood by people with ordinary skills in the field to which the present application belongs. The "first", "second" and similar words used in the embodiments of the present application do not represent any order, quantity or importance, but are only used to distinguish different components. "Including" or "comprising" and similar words mean that the elements or objects appearing in front of the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

"Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0055] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0056] Reference Figure 1 The present application provides an intelligent drainage method for a storage power station, comprising the following steps:

[0057] Step 102: Obtain the current water level depth in the power station in real time.

[0058] In this step, a plurality of water level monitoring sensors are installed in the power station, and the plurality of water level monitoring sensors are connected to the background management system. The water level monitoring sensors transmit the current monitored data (ie, the current water level depth) to the background management system in real time.

[0059] Step 104: Determine a target discharge amount of drainage according to a preset water level depth, the current water level depth and a water storage cross-sectional area of ​​the power station.

[0060] In this step, the preset water level depth can be a depth that requires a large amount of drainage, and an exemplary preset water level depth can be 0.5 meters. When the water in the power station exceeds the preset water level depth, a large amount of drainage is required. If it does not exceed the preset water level depth, the drainage volume can be converted by the pressure value in a conventional drainage method. Since the drainage volume is small, it will not cause the valve to be frequently started and stopped and adjusted drastically. Therefore, in this application, drainage is performed on power stations with a large amount of water. By calculating according to the preset water level depth, the current water level depth and the cross-sectional area of ​​the water storage station, the target discharge volume of the drainage point can be obtained, and then the valve opening can be determined according to the target discharge volume, so that the valve can be accurately controlled to avoid the problem of frequent start-stop and large-scale adjustment of the valve.

[0061] Step 106: Determine the valve opening according to the valve information and the target discharge volume of the drainage.

[0062] In this step, the valve information may include the valve cross-sectional area. Since different valves have different cross-sectional areas, the discharge amount of drainage is different. Therefore, the valve opening is determined according to the valve cross-sectional area and the target discharge amount of drainage. When the target discharge amount is constant, the larger the valve cross-sectional area, the smaller the valve opening.

[0063] Step 108: Determine the drainage time according to the valve opening and the target drainage volume.

[0064] In this step, the valve opening and the target discharge volume of drainage have been determined, so that the drainage time can be calculated, and the opening of the valve can be accurately controlled according to the valve opening and the drainage time.

[0065] Step 110: Control the valve to open according to the valve opening and the drainage time.

[0066] In this step, the background management system accurately controls the valve opening according to the calculated valve opening and drainage time, which can avoid the problem of energy consumption and wear of the valve caused by frequent start and stop and large-scale adjustment of the valve opening.

[0067] Through steps 102-110, the current water level depth in the power station is obtained in real time, and the target discharge amount of the drainage is calculated according to the preset water level depth, the current water level depth and the water storage cross-sectional area of ​​the power station, so that the valve opening can be determined according to the target discharge amount, so that the valve can be accurately controlled to avoid the problem of frequent start and stop of the valve and large-scale adjustment. After the valve opening and the target discharge amount of the drainage have been determined, the drainage time can be calculated, and the opening of the valve can be accurately controlled according to the valve opening and the drainage time.

[0068] In some embodiments, Figure 2As shown, the target discharge amount of drainage is determined according to the preset water level depth, the current water level depth and the water storage cross-sectional area of ​​the power station, including the following steps:

[0069] Step 202: Determine the required drainage depth according to the preset water level depth and the current water level depth.

[0070] In this step, the required drainage depth is determined based on the preset water level depth and the current water level depth, including: in response to the current water level depth being greater than the preset water level depth, subtracting the preset water level depth from the current water level depth to obtain the required drainage depth.

[0071] Specifically, the exemplary preset water level depth can be 0.5 meters. If the current water level depth is greater than 0.5 meters, the water exceeding 0.5 meters will be discharged, that is, the preset water level depth is subtracted from the current water level depth to obtain the required drainage depth. For example, if the current water level depth is 2 meters, 1.5 meters needs to be discharged, and the required drainage depth is 1.5 meters. In this way, the required drainage depth is calculated, and the target drainage volume of the drainage can be calculated according to the drainage depth and the water storage cross-sectional area of ​​the power station, and the target drainage volume of the drainage to be accurately determined, and then the valve opening can be determined, and the valve opening can be accurately controlled.

[0072] Step 204: Determine a target discharge amount of drainage according to the required drainage depth and the water storage cross-sectional area of ​​the power station.

[0073] In this step, determining the target discharge amount of drainage according to the required drainage depth and the water storage cross-sectional area of ​​the power station includes: multiplying the required drainage depth by the water storage cross-sectional area of ​​the power station to obtain the target discharge amount of drainage.

[0074] Specifically, by multiplying the drainage depth and the water storage cross-sectional area of ​​the power station, the target discharge volume required for the drainage depth can be obtained. The valve opening can be calculated based on the target discharge volume, thereby accurately controlling the valve.

[0075] In some embodiments, the valve information includes a valve cross-sectional area;

[0076] The step of determining the valve opening according to the valve information and the target discharge amount of the drainage includes:

[0077] In response to the valve cross-sectional area being within a first preset area range and the target drainage volume being within a first preset drainage volume range, determining the valve opening to be a first opening;

[0078] In response to the valve cross-sectional area being within a first preset area range and the target drainage volume being within a second preset drainage volume range, determining the valve opening to be a second opening, wherein the second opening is greater than the first opening;

[0079] In response to the valve cross-sectional area being within the second preset area range and the target displacement of the drainage being within the first preset displacement range, determining the valve opening to be a third opening, wherein the third opening is smaller than the first opening;

[0080] In response to the valve cross-sectional area being within a second preset area range and the target drainage volume being within a second preset drainage volume range, the valve opening is determined to be a fourth opening, wherein the fourth opening is smaller than the second opening and larger than the third opening.

[0081] Specifically, the cross-sectional area of ​​the valve is calculated based on the diameter of the valve, the radius of the valve is calculated based on the diameter of the valve, and the cross-sectional area of ​​the valve is calculated based on the circular area calculation formula. The specific formulas all use the area calculation formula, which will not be described in detail here. Exemplarily, the valve includes a butterfly valve and a ball valve, and the diameter range of the butterfly valve is: 1000mm to 10000mm, and the diameter of the ball valve is 500mm to 5000mm. The various ranges of the cross-sectional area of ​​the valve are exemplary: the first preset area range is: 10m 2- 40m 2 ; The second preset area range is: 41m 2 -80m 2 The first preset displacement range is: 1T-5T; the second preset displacement range is: 5.1T-10T. When the valve cross-sectional area (exemplary is 15m 2 ) is located in the first preset area (10m 2- 40m 2 ), and the target drainage volume (3T) is within the first preset drainage volume (1T-5T), the valve opening is determined to be the first opening (exemplarily 50%). 2 ) is located in the first preset area (10m 2- 40m 2 ) and the target drainage volume (6T) is within the second preset drainage volume (6T-10T), the valve opening is determined to be the second opening (exemplarily 100%).

[0082] When the valve cross-sectional area (exemplary is 45m 2 ) is located in the second preset area (41m 2 -80m 2), and the target drainage volume (3T) is within the first preset drainage volume (1T-5T), the valve opening is determined to be the third opening (exemplarily 30%). 2 ) is located in the second preset area (41m 2 -80m 2 ), and the target drainage volume (6T) is within the second preset drainage volume (6T-10T), the valve opening is determined to be the fourth opening (exemplarily 40%). In this way, different openings are controlled for different drainage volumes and different valve cross-sectional areas, avoiding frequent start-stop and large-scale adjustment of the valve and reducing valve loss.

[0083] In some embodiments, Figure 3 As shown, the drainage time is determined according to the valve opening and the target drainage amount, including the following steps:

[0084] 302. Determine the discharge volume per minute based on the valve cross-sectional area and the valve opening.

[0085] In this step, the determination of the emission per minute based on the valve cross-sectional area and the valve opening includes: in response to the valve cross-sectional area being within a first preset area range and the valve opening being a first opening, searching for the emission per minute corresponding to the first preset area range and the first opening in a preset valve opening and emission mapping table; in response to the valve cross-sectional area being within the first preset area range and the valve opening being a second opening, searching for the emission per minute corresponding to the first preset area range and the second opening in a preset valve opening and emission mapping table; in response to the valve cross-sectional area being within the second preset area range and the valve opening being a third opening, searching for the emission per minute corresponding to the second preset area range and the third opening in a preset valve opening and emission mapping table; in response to the valve cross-sectional area being within the second preset area range and the valve opening being a fourth opening, searching for the emission per minute corresponding to the second preset area range and the fourth opening in a preset valve opening and emission mapping table.

[0086] Specifically, the preset valve opening and emission volume mapping table is pre-stored in the background management system, and the valve opening and emission volume corresponding relationship mapping table includes valve opening and emission volume corresponding data of valves with different diameters. Since the valve opening of valves with different diameters has a certain emission volume, the emission volume is naturally easy to calculate based on the size and opening of the valve. The valve openings of different diameters and the calculated emission volume are stored as a valve opening and emission volume corresponding relationship mapping table. In order to directly determine the valve opening by looking up the table, the control speed of the control system can be improved and the calculation time can be saved. When the valve cross-sectional area is within the first preset area range and the valve opening is the first opening, the discharge per minute corresponding to the first preset area range and the first opening is searched in the preset valve opening and discharge amount mapping table; when the valve cross-sectional area is within the first preset area range and the valve opening is the second opening, the discharge per minute corresponding to the first preset area range and the second opening is searched in the preset valve opening and discharge amount mapping table; when the valve cross-sectional area is within the second preset area range and the valve opening is the third opening, the discharge per minute corresponding to the second preset area range and the third opening is searched in the preset valve opening and discharge amount mapping table; when the valve cross-sectional area is within the second preset area range and the valve opening is the fourth opening, the discharge per minute corresponding to the second preset area range and the fourth opening is searched in the preset valve opening and discharge amount mapping table; in this way, by directly determining the valve opening by table lookup, the control speed of the control system can be improved and the calculation time can be saved.

[0087] 304. Divide the target discharge amount by the discharge amount per minute to obtain drainage time.

[0088] In this step, the target discharge amount is divided by the discharge amount per minute to obtain the drainage time, including: the target discharge amount is divided by the discharge amount per minute corresponding to the first preset area range and the first opening to obtain the first drainage time; the target discharge amount is divided by the discharge amount per minute corresponding to the first preset area range and the second opening to obtain the second drainage time; the target discharge amount is divided by the discharge amount per minute corresponding to the second preset area range and the third opening to obtain the third drainage time; the target discharge amount is divided by the discharge amount per minute corresponding to the second preset area range and the fourth opening to obtain the fourth drainage time.

[0089] Specifically, for example, when the target discharge volume is 4T, the first preset area range and the first opening correspond to a discharge volume of 0.5T per minute, and the first drainage time is 8 minutes. When the target discharge volume is 4T, the first preset area range and the second opening correspond to a discharge volume of 0.8T per minute, and the second drainage time is 5 minutes. When the target discharge volume is 6T, the second preset area range and the third opening correspond to a discharge volume of 0.25T per minute, and the third drainage time is 24 minutes. When the target discharge volume is 6T, the second preset area range and the fourth opening correspond to a discharge volume of 0.3T per minute, and the fourth drainage time is 20 minutes. By calculating the discharge time according to the target discharge volume and the corresponding valve opening, the valve opening and the time it is opened at this opening can be accurately controlled.

[0090] In some embodiments, based on the above embodiments, controlling the valve opening according to the valve opening and the drainage time includes:

[0091] In response to the cross-sectional area of ​​the valve being within a first preset area range and the valve opening being a first opening, controlling the valve opening time to be as long as a first drainage time;

[0092] In response to the cross-sectional area of ​​the valve being within the first preset area range and the valve opening being at a second opening, controlling the valve opening time to be as long as a second drainage time;

[0093] In response to the cross-sectional area of ​​the valve being within the second preset area range and the valve opening being a third opening, controlling the valve opening time to be as long as a third drainage time;

[0094] In response to the valve cross-sectional area being within the second preset area range and the valve opening being a fourth opening, the valve opening time is controlled to be as long as a fourth drainage time.

[0095] Specifically, based on the above embodiments, valves of different diameters, valve openings, and drainage times corresponding to the valve openings have been calculated. Then, according to the diameter of the valve, the valve opening and drainage time are calculated for control. When the cross-sectional area of ​​the valve is within the first preset area range and the valve opening is the first opening, the valve opening time is controlled to be as long as the first drainage time; when the cross-sectional area of ​​the valve is within the first preset area range and the valve opening is the second opening, the valve opening time is controlled to be as long as the second drainage time; when the cross-sectional area of ​​the valve is within the second preset area range and the valve opening is the third opening, the valve opening time is controlled to be as long as the third drainage time; when the cross-sectional area of ​​the valve is within the second preset area range and the valve opening is the fourth opening, the valve opening time is controlled to be as long as the fourth drainage time. In this way, according to the diameter of the valve, the valve opening and drainage time are calculated for control, the corresponding valve can be accurately controlled, the intelligent adjustment of the drainage system can be realized, and the problem of frequent and large-scale adjustment of the valve, which leads to increased energy consumption and wear of the valve, can be avoided.

[0096] It should be noted that the method of the embodiment of the present application can be performed by a single device, such as a computer or server. The method of this embodiment can also be applied to a distributed scenario and completed by multiple devices cooperating with each other. In the case of such a distributed scenario, one of the multiple devices can only perform one or more steps in the method of the embodiment of the present application, and the multiple devices will interact with each other to complete the described method.

[0097] It should be noted that the above describes some embodiments of the present application. Other embodiments are within the scope of the appended claims. In some cases, the actions or steps recorded in the claims can be performed in an order different from that in the above embodiments and still achieve the desired results.
