[0073] See also Figure 1 , Figure 1 The generalized diagram of the water supply system provided in the embodiment of the present application is described as follows:

[0074] Among them, the generalized map of the water supply system includes waterways, water intakes, reservoirs, water plants and water demand areas.

[0075] The water intake draws river water from the waterway, the water intake transports river water to the reservoir, the reservoir transports river water to the water plant, and the water plant transports purified river water to the water-demanding area.

[0076] When the water diversion and regulation project involves this waterway, the electronic device obtains the salinity of the water intake of the water diversion and regulation project on the day before water diversion, the salinity of the previous day, the average daily flow, the daily maximum tidal range and the average daily salinity. The salinity on the day is the salinity of the river water flowing into the water intake on the day, and the salinity on the previous day is the salinity of the river water on the previous day.

[0077] Among them, the salinity of the day, the salinity of the previous day, the average daily flow, the maximum daily tidal range and the average daily salinity can come from one database or from multiple databases.

[0078] For ease of explanation, two databases are used as examples, as detailed below:

[0079] The two databases include database A and database B. The electronic device is connected to database A and database B respectively, and obtains the salinity of the day, the salinity of the previous day, the average daily flow, the maximum daily tidal range and the average daily salinity from database A and database B.

[0080] In an embodiment of the present application, the electronic device can be connected to different databases at the same time to obtain the salinity of the day, the salinity of the previous day, the average daily flow, the maximum daily tidal range and the average daily salinity from the different databases.

[0081] See also Figure 2 , Figure 2 It is a flow chart of the impact analysis method provided in an embodiment of the present application, which can be applied to electronic devices.

[0082] like Figure 2 As shown, the impact analysis method provided in the embodiment of the present application includes the following steps, which are described in detail as follows:

[0083] S201, obtaining the salinity of the water intake of the water diversion project on the current day, the salinity of the previous day, the average daily flow, the maximum daily tidal range, and the average daily salinity before water diversion, wherein the salinity on the current day is the salinity of the river water flowing into the water intake on the current day, and the salinity of the previous day is the salinity of the river water on the previous day;

[0084] The dispatching and operation of the water diversion project is based on the water inflow of the upstream water conservancy hub station S. Project 1 is an unbuilt water diversion project and does not take water; Project 2 is a built water diversion project, with the water intake location at intake 1 and the water intake flow rate of Am3 / s.

[0085] For ease of explanation, refer to Table 1, which is a design engineering table, as detailed below:

[0086]

[0087] The obtaining of statistical data of the water intake of the water diversion project before water diversion includes:

[0088] Obtaining a preset statistical time, and obtaining the runoff data, tide level data, and salinity data of the water intake before water diversion;

[0089] In the salinity data, the salinity of the current day and the salinity of the previous day are obtained;

[0090] Determine the average daily flow rate according to the runoff data and the statistical time;

[0091] Determining the daily maximum tidal range according to the tidal level data and the statistical time;

[0092] The daily average salinity is determined according to the salinity data and the statistical time.

[0093] S202, generating a saltwater intrusion value of the water intake according to the salinity of the day, the average daily flow, the maximum daily tidal range, the salinity of the previous day, a wind speed correction term, and a preset saltwater intrusion statistical model, wherein the saltwater intrusion value is used to describe the degree of saltwater intrusion into the river water, and the saltwater intrusion statistical model is a generation model of the saltwater intrusion value;

[0094] The larger the saltwater intrusion value is, the more serious the degree of the saltwater intrusion into the river water is; and the smaller the saltwater intrusion value is, the less serious the degree of the saltwater intrusion into the river water is.

[0095] Exemplarily, the saltwater intrusion statistical model is:

[0096] S=a*e -bQ +c*H+d*G+r;

[0097] Among them, S is the salinity of the day, Qi is the average daily flow rate; H is the maximum daily tidal range; G is the salinity of the previous day; r is the wind speed correction term, and a, b, c, and d are preset coefficients.

[0098] Among them, when the wind direction is in the positive direction, the wind speed correction term is a positive value, and when the wind direction is in the negative direction, the wind speed correction term is a negative value.

[0099] The positive direction is set by the user or by the system by default and is not restricted here.

[0100] Among them, a, b, c, and d are set by the user or by the system by default and are not limited here.

[0101] For the sake of illustration, an example is given below:

[0102] For example, a = 2.5, b = 0.00015, c = -0.65, d = 0.63, r = -0.63, then the obtained saltwater intrusion statistical model is:

[0103] S=2.5*e- 0.00015Q -0.65*H+0.63*G-0.63;

[0104] For the sake of illustration, an example is given below:

[0105] For example, a = 2.5, b = 0.00016, c = -0.65, d = 0.63, r = 0.7, then the obtained saltwater intrusion statistical model is:

[0106] S=2.5*e- 0.00016Q -0.65*H+0.63*G+0.7;

[0107] Among them, the salt water intrusion value of the water intake is stored in a preset file for subsequent retrieval.

[0108] S203, when the saltwater intrusion value is less than a first preset value, obtaining an impact area of ​​the saltwater tide;

[0109] S204, obtaining a first distance of a salt-fresh water boundary line moving toward the water intake in the affected area, wherein the salt-fresh water boundary line is a boundary line between the salt water upstream of the salt tide and the river water;

[0110] Wherein, obtaining the first distance of the salt-fresh water boundary line moving toward the water intake in the affected area includes:

[0111] Obtaining the water intake area of ​​the water intake, and determining whether there is an overlapping area between the impact area and the water intake area;

[0112] If there is an overlapping area between the impact area and the water area, the first distance of the fresh-salt water boundary moving toward the water intake is obtained in the overlapping area, and the overlapping area is a partial area of ​​the impact area.

[0113] S205, when the first distance is less than a preset second distance, obtaining the water intake time of the water intake after the water transfer, the water intake time being the time for taking the river water within a preset time period;

[0114] S206, obtaining the water intake speed of the water intake port, and obtaining the water intake volume of the water intake port in the time period according to the product of the water intake speed and the water intake time;

[0115] Wherein, obtaining the water intake speed of the water intake port, and obtaining the water intake amount of the water intake port in the time period according to the product of the water intake speed and the water intake time, comprises:

[0116] Acquire a water intake rate of the water intake, where the water intake rate is a ratio of the water intake time to the time period;

[0117] Determining whether the de-blurring rate is greater than a second preset value;

[0118] If the desalination rate is greater than the second preset value, obtaining the water intake speed of the water intake port;

[0119] The water intake volume of the water intake port in the time period is obtained according to the product of the water intake speed and the water intake time.

[0120] For the sake of explanation, the waterway is taken as SD waterway and the water diversion project is taken as Project 2 as an example. The following are some examples:

[0121] The desalination rate before water diversion in the water diversion project is referred to as the pre-project desalination rate.

[0122] The desalination rate after water diversion in the water diversion project is referred to as the post-project desalination rate.

[0123] The SD waterway has multiple water intakes, and the multiple water intakes are respectively water intake 1, water intake 2, and water intake 3.

[0124] The desalination rates before the project at water intake 1, water intake 2, and water intake 3 are reduced by 0.93%, 0.32%, and 1.68% respectively compared with the desalination rates after the project at water intake 1, water intake 2, and water intake 3.

[0125] Therefore, Project 2 has little impact on the desalination rates of Intake 1, Intake 2, and Intake 3.

[0126] When the designed inflow of Project 2 at Station S is X1 m3 / s, the fresh and salt water boundary line of the SD waterway moves up by about 0.42 km, that is, the first distance is 0.42 km.

[0127] Among them, water intake 1, water intake 2, and water intake 3 are different water intakes.

[0128] For the sake of explanation, refer to Table 2, which is a table showing the variation of the dilution rate, as detailed below:

[0129]

[0130] S207, obtaining the water demand of the water demand area of ​​the downstream water supply system in the time period, and generating a minimum water shortage rate according to the water demand, the water intake, the number of the time periods, the number of the water demand areas and a preset water shortage rate generation model. The minimum water shortage rate is used to describe the minimum impact of the water diversion and regulation project on the water demand area. The water shortage rate generation model is a generation model of the water shortage rate.

[0131] Among them, the larger the minimum water shortage rate is, the greater the minimum impact of the water diversion and regulation project on the water demand area is, and the smaller the minimum water shortage rate is, the smaller the minimum impact of the water diversion and regulation project on the water demand area is.

[0132] Exemplarily, the water shortage rate generation model is:

[0133]

[0134] Where, f is the minimum water shortage rate, D kt is the water demand of the kth water demand area in the tth time period, q t is the water intake of the water intake in the tth time period, t∈[1,T], T is the number of the time periods, t is the sequence number of the time periods, k∈[1,M], k is the sequence number of the water demand area, M is the number of the water demand areas, and min is the minimization function.

[0135] The time period is set by the user or by system default and is not restricted here.

[0136] For ease of explanation, the time period is month, as follows:

[0137] For example, when the number of time periods is set to 3, the first time period is January of this year, the second time period is February of this year, and the third time period is March of this year.

[0138] For example, when the number of time periods is set to 5, the first time period is November of this year, the second time period is December of this year, the third time period is January of next year, the fourth time period is February of next year, and the third time period is March of next year.

[0139] Wherein, after obtaining the water demand of the water demand area of ​​the downstream water supply system in the time period, generating the minimum water shortage rate according to the water demand, the water intake, the number of the time period, the number of the water demand areas and a preset water shortage rate generation model, the impact analysis method further includes:

[0140] Step A, obtaining the water storage capacity of the reservoir corresponding to the water intake within the time period.

[0141] Wherein, after obtaining the water demand of the water demand area of ​​the downstream water supply system in the time period, generating the minimum water shortage rate according to the water demand, the water intake, the number of the time period, the number of the water demand areas and a preset water shortage rate generation model, the impact analysis method further includes:

[0142] Step B, obtaining the water replenishment amount of the reservoir corresponding to the water intake within the time period, wherein the water replenishment amount is the amount of water supplemented by the reservoir to the downstream water supply system.

[0143] Wherein, obtaining the water replenishment amount of the reservoir corresponding to the water intake within the time period includes:

[0144] Determining whether the minimum water shortage rate is greater than a third preset value;

[0145] If the minimum water shortage rate is greater than the third preset value, the water replenishment volume of the reservoir corresponding to the water intake within the time period is obtained.
