[0082] In step S100, the flow information of all booster stations is acquired, and the current water supply scheduling stage is determined according to the flow information; wherein the water supply scheduling stage includes the booster station water inlet stage and the booster station water outlet stage.

[0083] Specifically, according to the flow information, the current water supply scheduling stage is determined, which can be achieved by obtaining the water inflow value and the water outflow value of all the booster stations, obtaining the flow information of all the booster stations according to the water inflow value and the water outflow value, and comparing the flow value corresponding to the flow information with the flow value range of the water inflow stage and the flow value range of the water outflow stage to determine the current water supply scheduling stage.

[0084] In step S200, if the current water supply scheduling stage is the booster station water inflow stage, the pressure value of the water supply pipeline is obtained, and the booster station water inflow stage scheduling instruction is generated according to the scheduling range in which the pressure value of the water supply pipeline is located.

[0085] Specifically, according to the scheduling range in which the pressure value of the water supply pipeline is located, the booster station water inflow stage scheduling instruction can be generated by obtaining the first preset lower limit value and the first preset upper limit value of the pressure of the water supply pipeline, judging the scheduling state in which the current water supply pipeline is located according to the pressure value of the water supply pipeline, generating the booster station first water inflow stage scheduling instruction when the scheduling state is the booster station first water inflow stage scheduling state, and generating the booster station second water inflow stage scheduling instruction when the scheduling state is the booster station second water inflow stage scheduling state.

[0089] After that, if yes, the booster station first water inflow stage scheduling instruction is sent to the booster station satisfying the first condition, and the scheduling component corresponding to the booster station satisfying the first condition is driven to perform the scheduling action of reducing the water inflow flow; otherwise, according to the running state and / or historical scheduling instruction of the gravity flow water plant, the booster station first water inflow stage scheduling instruction is sent to the corresponding flow control station of the gravity flow water plant or the pump pressure flow water plant, and the scheduling component corresponding to the corresponding flow control station of the gravity flow water plant or the pump pressure flow water plant is driven to perform the scheduling action of increasing the water outflow flow.

[0090] Further, when the operation state of the gravity flow water plant is that the water outflow load exceeds the preset load value, the first water inflow stage scheduling instruction of the pressurizing station is sent to the pump pressure water plant, otherwise the first water inflow stage scheduling instruction of the pressurizing station is sent to the corresponding flow control station of the gravity flow water plant.

[0091] Further, when there are M pieces of the first water inflow stage scheduling instruction of the pressurizing station sent to the corresponding flow control station of the gravity flow water plant in the previous N minutes in the historical scheduling instruction, the first water inflow stage scheduling instruction of the pressurizing station is sent to the pump pressure water plant, otherwise the first water inflow stage scheduling instruction of the pressurizing station is sent to the corresponding flow control station of the gravity flow water plant.

[0092] In the preferred embodiment, when the water inflow stage scheduling instruction of the pressurizing station is the second water inflow stage scheduling instruction, it is necessary to determine whether there is a pressurizing station satisfying the second condition according to the flow information of all pressurizing stations; wherein the second condition is that the water inflow flow corresponding to the flow information can be increased.

[0093] After that, if the second water inflow stage scheduling instruction of the pressurizing station is sent to the pressurizing station satisfying the second condition, the scheduling component corresponding to the pressurizing station satisfying the second condition is driven to perform the scheduling action of increasing the water inflow flow; otherwise, according to the operation state of the pump pressure water plant, the second water inflow stage scheduling instruction of the pressurizing station is sent to the corresponding flow control station of the gravity flow water plant or the pump pressure water plant, and the scheduling component corresponding to the corresponding flow control station of the gravity flow water plant or the pump pressure water plant is driven to perform the scheduling action of reducing the water outflow flow.

[0094] Further, when the operation state of the pump pressure water plant is that all the water outflow pumps of the pump pressure water plant are closed, the second water inflow stage scheduling instruction of the pressurizing station is sent to the corresponding flow control station of the gravity flow water plant, otherwise the second water inflow stage scheduling instruction of the pressurizing station is sent to the pump pressure water plant.

[0095] In step S400, if the current water supply scheduling stage is the pressurizing station water outflow stage, the pressure value of the water supply pipeline is obtained, and the pressurizing station water outflow stage scheduling instruction is generated according to the scheduling range in which the pressure value of the water supply pipeline is located.

[0096] Specifically, generating the pressurizing station water outflow stage scheduling instruction according to the scheduling range in which the pressure value of the water supply pipeline is located can be achieved by obtaining the second preset lower limit pressure value and the second preset upper limit pressure value of the water supply pipeline, determining the scheduling state in which the current water supply pipeline is located according to the pressure value of the water supply pipeline, generating the first water outflow stage scheduling instruction of the pressurizing station when the scheduling state is the first water outflow stage scheduling state of the pressurizing station, and generating the second water outflow stage scheduling instruction of the pressurizing station when the scheduling state is the second water outflow stage scheduling state of the pressurizing station.

[0097] In the preferred embodiment, when the pressure value of the water supply pipeline is less than the second preset pressure lower limit value, the scheduling state is the first water outlet stage scheduling state of the pressurizing station; when the pressure value of the water supply pipeline is greater than the second preset pressure upper limit value, the scheduling state is the second water outlet stage scheduling state of the pressurizing station.

[0098] Step S500, sending the water outlet stage scheduling instruction of the pressurizing station to the corresponding flow control station of the gravity flow water plant, or the pump pressure flow water plant, or the pressurizing station, to realize the water outlet stage scheduling of the pressurizing station.

[0099] In the preferred embodiment, when the water outlet stage scheduling instruction of the pressurizing station is the first water outlet stage scheduling instruction of the pressurizing station, according to the running state and / or historical scheduling instruction of the gravity flow water plant, the first water outlet stage scheduling instruction of the pressurizing station is sent to the corresponding flow control station of the gravity flow water plant, or the pump pressure flow water plant, or the pressurizing station, to drive the corresponding scheduling component of the flow control station of the gravity flow water plant, or the pump pressure flow water plant, or the pressurizing station to perform the scheduling action of increasing the water outlet flow.

[0100] Further, when the running state of the gravity flow water plant is that the water outlet load exceeds the preset load value, the first water outlet stage scheduling instruction of the pressurizing station is sent to the pump pressure flow water plant, or the pressurizing station, otherwise the first water outlet stage scheduling instruction of the pressurizing station is sent to the corresponding flow control station of the gravity flow water plant.

[0101] Further, when there are M pieces of the first water outlet stage scheduling instruction of the pressurizing station sent to the corresponding flow control station of the gravity flow water plant in the previous N minutes in the historical scheduling instruction, the first water outlet stage scheduling instruction of the pressurizing station is sent to the pump pressure flow water plant, or the pressurizing station, otherwise the first water outlet stage scheduling instruction of the pressurizing station is sent to the corresponding flow control station of the gravity flow water plant.

[0102] At the same time, for the sending of the above-mentioned first water outlet stage scheduling instruction of the pressurizing station, when any pressurizing station satisfies that the predicted liquid level difference of the clear water tank after starting the pump is greater than 0, the first water outlet stage scheduling instruction of the pressurizing station is sent to the pressurizing station, otherwise the first water outlet stage scheduling instruction of the pressurizing station is sent to the pump pressure flow water plant.

[0103] In the preferred embodiment, when the water outlet stage scheduling instruction of the pressurizing station is the second water outlet stage scheduling instruction of the pressurizing station, according to the water outlet flow of the pressurizing station and the pump pressure flow water plant, it is judged whether the pressurizing station and the pump pressure flow water plant are completely closed.

[0104] After that, if yes, the second water outlet stage scheduling instruction of the pressurizing station is sent to the corresponding flow control station of the gravity flow water plant to drive the corresponding scheduling component of the corresponding flow control station of the gravity flow water plant to perform the scheduling action of reducing the water outlet flow; otherwise, the second water outlet stage scheduling instruction of the pressurizing station is sent to the pump pressure flow water plant or the pressurizing station to drive the corresponding scheduling component of the pump pressure flow water plant or the pressurizing station to perform the scheduling action of reducing the water outlet flow.

[0105] Further, when the number of pressurizing stations with pumps opened is greater than 0, the second water outlet stage scheduling instruction of the pressurizing station is sent to the pressurizing station; otherwise, the second water outlet stage scheduling instruction of the pressurizing station is sent to the pump pressure flow water plant.

[0106] The embodiment provides a multi-water-source urban water supply scheduling method, which breaks the dependence of urban tap water scheduling on manual operation by scheduling stage judgment, pipe network master control point pressure information monitoring and water supply node flow acquisition, and realizes safe and economic operation of the urban water supply system.

[0107] In order to more clearly explain the present application, a specific example of a multi-water-source urban water supply scheduling method is provided.

[0108] Referring to Figure 3 In the embodiment, a specific example of a multi-water-source urban water supply scheduling method is provided, which includes the following steps:

[0109] Step 1: Obtain the water inlet and outlet flow information of the pressurizing station, and judge the current scheduling stage.

[0110] In the embodiment, the information of all pressurizing stations with clean water pools in the urban water supply system is obtained through the SCADA system of the tap water company, including the running state of all water outlet pumps of each pressurizing station, the water inlet valve opening, the water inlet flow, the water outlet flow, the clean water pool liquid level data and the like, the state of the whole pressurizing station in the urban water supply system is judged, if there is a pressurizing station with water inlet flow greater than 100 m 3 / h or the clean water pool liquid level in the rising state, it is judged that the whole pressurizing station is in the water inlet state, at this time the pressurizing station is used as a water storage facility; if there is a pressurizing station with water outlet flow greater than 100 m 3 / h or the clean water pool liquid level in the descending or unchanged state, it is judged as the water outlet state, at this time the pressurizing station is used as a water source supply pipe network. By confirming the current state of the pressurizing station, the current scheduling stage is determined, which lays a foundation for subsequent instruction recommendation to the scheduling personnel.

[0111] Step 2: Obtain the real-time information of the pipe network master control point pressure, and judge the schedulable object after the pressure overrun.

[0112] In the embodiment, the real-time data of the pipe network master control point pressure in the urban water supply system is obtained through the SCADA system of the tap water company.

[0113] In this embodiment, as shown in Figure 4 The scheduling objects include two gravity flow water plants (including six corresponding flow control stations), two pump pressure water plants, and three pressure stations.

[0114] In this embodiment, according to the change of urban water demand and the real-time change coefficient (K h 1.3-1.5), combined with the factors of weekends and weekdays in spring (March-May), summer (June-August), autumn (September-November), and winter (December-February of the next year), and legal holidays, the upper and lower limit values of the main control point pressure of the pipe network in different water use periods in a day are set as the scheduling instruction trigger conditions, and the specific settings are shown in Table 1.

[0115] Table 1: List of upper and lower limit values of main control point pressure of pipe network in different periods

[0116]

[0117]

[0118] In this embodiment, the economic priority order of the schedulable objects is gravity flow water plant A (including phase 1, phase 2, phase 3, phase 4, and phase 5) > gravity flow water plant B > pressure station (supplemented by gravity flow water plants A and B, including pressure stations A, B, and C) > pump pressure water plant C > pump pressure water plant D > pressure station (supplemented by pump pressure water plants C and D); wherein the gravity flow water plant A (including phase 1, phase 2, phase 3, phase 4, and phase 5) adjusts the water flow through five flow control valve stations, and the gravity flow water plant B adjusts the water flow through one flow control valve station.

[0119] In this embodiment, the maximum water flow of each water plant and pressure station in different water use periods in a day is set according to the seasons of spring (March-May), summer (June-August), autumn (September-November), and winter (December-February of the next year), and the specific settings are shown in Table 2, wherein the water flow of pressure stations A, B, and C is negative, indicating that the pressure station is in the water inlet stage during the scheduling stage. According to the obtained real-time information of each water plant and pressure station, the current water flow load of each water plant and pressure station, the target liquid level at the next target time, the effective adjustment volume of the water tank of each water plant and pressure station, and the effective adjustment volume of the company can be calculated in real time, as shown in Table 5.

[0120] Table 2: List of maximum water flow of each water plant and pressure station (unit: m 3 / h)

[0121]

[0122]

[0123] In this embodiment, the limit scheduling quantity of each water plant and pressure station is set, including the maximum opening degree, minimum opening degree, single valve opening degree and pressure difference before and after the valve of the flow control valve corresponding to the gravity flow water plant, the maximum number of pumps (including large and small pumps) of each pump pressure flow water plant and pressure station, and the single water inflow of the pressure station. The pressure difference before and after the valve of the flow control station is 0.02 MPa (i.e. it is considered to reach the scheduling limit). The details are shown in Table 4.

[0124] In this embodiment, the maximum water outflow of all water plants and pressure stations in a day is set according to the time period of the season as shown in Table 2, and the water outflow load of each water plant and pressure station is calculated according to the obtained real-time information. The details are shown in Table 5. The water outflow load = current water outflow / set current time period maximum water outflow * 100%, if the water outflow load is less than 95%, it is considered to be under load, if the water outflow load is between 95% and 105%, it is considered to be full load, and if the water outflow load is greater than 105%, it is considered to be overload.

[0125] In this embodiment, according to the scheduling redundancy, the target liquid level of the clean water tank of all water plants and pressure stations in different time periods in a day in spring, summer, autumn and winter is set, as shown in Table 3.

[0134] Table 6: List of clean water tanks of water plants and pressure stations

[0135]

[0136] In this embodiment, according to the real-time information of all water plants and pressure stations collected by the SCADA system, the predicted liquid level and predicted liquid level difference of all water plants and pressure stations at the next target time are calculated. The predicted liquid level = current liquid level + (current water inflow - current water outflow) * (target time - current time) / clean water tank bottom area, and the predicted liquid level difference = predicted liquid level - target time target liquid level. The details are shown in Table 5.

[0137] In this embodiment, according to the real-time information of all water plants and booster stations collected by the SCADA system, the required time for all water plants and booster stations to reach the target liquid level of the clear water tank is calculated, wherein the required time = (target liquid level - current liquid level) * clear water tank per meter volume / (current water inflow - current water outflow), and the specific list is shown in Table 5.

[0138] In this embodiment, according to the real-time information of all water plants and booster stations collected by the SCADA system, the liquid level change speed of all water plants and booster stations is calculated, which is usually expressed in cm / 5min, wherein the liquid level change speed of the clear water tank = 100 * (current liquid level - liquid level 5min ago) / 5min, and the specific list is shown in Table 5.

[0139] In this embodiment, according to the real-time information of all water plants and booster stations collected by the SCADA system, the effective adjustment volume of the clear water tank of all water plants and booster stations is calculated, and then the effective adjustment volume of the company is obtained; wherein the effective adjustment volume of the clear water tank of all water plants and booster stations = (current liquid level - minimum operating liquid level) * clear water tank per meter volume, and finally the effective adjustment volume of all water plants and booster stations is superimposed to obtain the effective adjustment volume of the company, and the specific list is shown in Table 5.

[0140] In this embodiment, the relevant information of the clear water tank of each water plant and booster station is shown in Table 6.

[0141] Step three, obtaining real-time information of schedulable objects, and finding schedulable objects meeting the preset scheduling strategy.

[0142] In this embodiment, the real-time information of each water plant, flow control station, booster station and pipe network master control point is obtained through the SCADA system.

[0143] In this embodiment, in the step of finding schedulable objects meeting the preset scheduling strategy, there are two states of the booster station and two trends of the pipe network master control point pressure, which are described in four cases.

[0144] 1. When the booster station is in the water inflow stage, and the pipe network master control point pressure is below the lower limit, the specific flow is shown in Figure 5 , and the following steps are performed:

[0145] 1.1. Determine whether there is a booster station that can reduce the water inflow. Specifically, the booster station that can reduce the water inflow requires to meet the conditions that the water inflow is greater than 100 m 3 / h, and the expected liquid level difference is greater than 0, and the expected liquid level difference is calculated as expected liquid level difference = current liquid level + (current water inflow - each proposed default reduced flow) * (target time - current time) / clear water tank bottom area - target liquid level.

[0146] 1.1.1 If it is judged that there is a pressurizing station meeting the condition, proceed to the step of reducing the water inflow of the pressurizing station. In this step, the expected inflow time of each pressurizing station is also calculated and sorted in ascending order. Specifically, the expected inflow time = (the highest operating liquid level of the clear water tank - the current liquid level) * the volume per meter of the clear water tank / (the current inflow - the current outflow).

[0147] 1.1.2 According to the pressure regulation requirement of the network master control point, select the pressurizing station with the smallest expected inflow time to reduce the inflow first, and then calculate and alternate the reduction until the inflow of all pressurizing stations is less than 100 m 3 / h. Specifically, in this embodiment, the inflow of the pressurizing station is reduced by the default value of 1500 m 3 / h each time, and if the current inflow is less than 1500 m 3 / h, the inflow is directly reduced to 0 (theoretically).

[0148] 1.2 If it is judged that the expected liquid level difference of each pressurizing station under the current state is less than 0, or the inflow is less than 100 m 3 / h, i.e., there is no pressurizing station that can reduce the inflow, the outflow of the water plant (including gravity flow and pump pressure flow) is increased to achieve the pressure regulation of the network master control point. Specifically, first determine whether one of the following conditions is met: the outflow load of the gravity flow water plant is all above 100% or the previous N minutes have recommended M flow control station flow valves and the opening of the outflow pump scheme.

[0149] 1.2.1 If it is judged that the condition is met, select the pump pressure flow water plant to increase the outflow pump to achieve the pressure regulation of the network master control point. Specifically, the pump pressure flow water plant with the smallest outflow load is preferentially selected to be opened. In this embodiment, the large pump is preferentially opened, and then the small pump is opened until the pump pressure flow water plant is running at full load.

[0150] 1.2.2 If it is judged that the condition is not met, select the gravity flow water plant to increase the outflow to achieve the pressure regulation. Specifically, select the flow control station valve that has operability to adjust, and increase the opening of the flow control station valve corresponding to the gravity flow water plant with the lowest outflow load; wherein, the opening of the flow valve with the largest pressure difference before and after the valve is preferentially adjusted, and the opening of the flow valve is increased by the default value each time until the flow valve reaches the maximum opening or the pressure difference before and after the valve reaches the effective pressure difference. In this embodiment, any one of the conditions that the liquid level of the gravity flow water plant is higher than the lower limit of the target liquid level at the current time, the expected liquid level at the next target time is higher than the target liquid level at the target time, the pressure difference before and after the flow control station valve is higher than the effective pressure difference, and the opening of the flow control station valve is less than the maximum opening is considered as the operability of the corresponding flow control station. If the flow control station is A and B dual valve operation, the flow valve with the smaller opening is selected to be opened first, and the valves are alternately dispatched. The default adjustment opening of the valve is 10 degrees each time for single valve operation, and the default adjustment opening of the valve is 15 degrees each time for dual valve operation.

[0151] 2. When the pressurizing station is in the water inflow stage, and the pipe network master control point pressure exceeds the upper limit, the specific process is as shown in the following steps: Figure 4

[0152] 2.1 Determine whether there is a pressurizing station that can increase the water inflow. Specifically, the pressurizing station that can increase the water inflow requires that the predicted liquid level difference is less than 0 after increasing the default water inflow under the current water inflow, and the predicted liquid level difference is calculated as predicted liquid level difference = current liquid level + (current water inflow + each proposed default reduced flow) * (target time - current time) / clean water tank bottom area - target liquid level.

[0153] 2.1.1 If it is determined that there is a pressurizing station that meets the conditions, proceed to the step of increasing the water inflow of the pressurizing station. This step also includes calculating the predicted water inflow time of each pressurizing station and sorting them in descending order. Specifically, the predicted water inflow time = (clean water tank maximum operating liquid level - current liquid level) * clean water tank per meter volume / (current water inflow - current water outflow)

[0154] 2.1.2 According to the pipe network master control point pressure adjustment and reduction demand, select the pressurizing station with the longest predicted water inflow time to increase the water inflow first, and then calculate in a loop, alternatingly increasing, until all pressurizing station clean water tank liquid levels reach the target liquid level. Specifically, in this embodiment, the water inflow of the pressurizing station is increased by the default value of 1500m 3 / h each time, and the last time is increased by the calculated value if it is less than 1500m 3 / h.

[0155] 2.2 If it is determined that the predicted liquid level difference of each pressurizing station under the current state is greater than 0, or the water inflow is less than 100m 3 / h, that is, there is no pressurizing station that can increase the water inflow, then the pipe network master control point pressure is adjusted and controlled by reducing the water plant (including gravity flow and pump pressure flow) water outflow. Specifically, first determine whether the pump pressure flow water plant water outflow pump is completely closed, which is achieved by determining whether the number of pump pressure flow water plant water outflow pumps is greater than 0 or the water outflow is greater than 100m 3 / h in this embodiment.

[0156] ​2.2.1 If it is judged that all the pump pressure water plants in the current state have been completely closed, the outflow of the operable gravity flow water plant is reduced. Specifically, the valve before and after the pressure difference of the flow control station is selected to operate the valve to close, until the flow valve reaches the minimum opening. In this embodiment, any one of the conditions that the gravity flow water plant clear water pool liquid level is higher than the current time target liquid level upper limit, the next target time predicted liquid level is higher than the target time target liquid level upper limit, the flow control station valve before and after the pressure difference is less than the effective pressure difference, and the flow control station valve opening is greater than the minimum opening is considered to have operability. If the flow control station is A and B double valve operation, the larger flow valve is selected to close first, and the valves are alternately scheduled. The default adjustment opening of the valve is 10 degrees each time for single valve operation, and the default adjustment opening of the valve is 15 degrees each time for double valve operation.

[0157] 2.2.2 If it is judged that the pump pressure water plant outflow pump is not completely closed, the pump pressure water plant outflow pump is selected to reduce the pipe network master control point pressure regulation. Specifically, the pump with the largest outflow load is selected to stop first. In this embodiment, the small pump is closed first, and if there is no small pump, the large pump is closed.

[0158] 3. When the pressurizing station is in the outflow stage, and the pipe network master control point pressure is below the lower limit, the specific process is as shown in Figure 6 , and the following steps are performed:

[0159] 3.1 Calculate the outflow load of each gravity flow water plant in the current state.

[0160] 3.2 Judge whether the current state satisfies one of the following conditions: the outflow load of each gravity flow water plant is above 100%, or the recommended execution of M outflow pump (or flow control valve) scheduling scheme within the previous N minutes. In this embodiment, 3 outflow pumps or flow control valves are recommended to be opened within the previous 2 minutes.

[0161] 3.3 If it is judged that any one of the conditions in 3.2 is satisfied, the pump pressure water plant or the pressurizing station outflow is selected to increase to regulate the pipe network master control point pressure. Specifically, it is first judged whether any pressurizing station satisfies the condition that the predicted liquid level difference after opening the pump is greater than 0. The predicted liquid level difference is calculated as predicted liquid level difference = current liquid level - (current outflow + rated flow of the pump to be opened) * (target time - current time) / clear water pool bottom area - target time target liquid level.

[0162] 3.3.1 If it is judged that the condition in 3.3 is satisfied, the pressurizing station outflow is selected to increase to regulate the pipe network master control point pressure. Specifically, the pressurizing station with the longest water supply time after opening the pump is selected to open the pump. In this embodiment, the large pump is opened first, and then the small pump is opened. The water supply time = (target time target liquid level - current liquid level) * clear water pool volume per meter / (current outflow + rated flow of the pump to be opened).

[0163] 3.3.2 If it is judged that the condition 3.3 is not satisfied, the water flow of the pump pressure water plant is selected to be increased to realize the pressure regulation of the main control point of the pipe network. Specifically, the pump pressure water plant with the smallest water discharge load is selected to be operated. In this embodiment, the pump pressure water plant is considered to be operable if any of the following conditions is satisfied: the water discharge of the water plant is not full load, or the number of pumps operated in the water plant does not reach the maximum number of pumps that can be operated. A large pump is preferentially selected to be operated, and a small pump can be selected to be operated if there is no large pump.

[0164] 3.4 If it is judged that any of the conditions in 3.2 is not satisfied, the water flow of the gravity flow water plant is selected to be increased.

[0165] 3.4.1 The control flow station corresponding to the gravity flow water plant that is operable is selected. Specifically, the gravity flow water plant that is operable refers to the water plant that satisfies the following conditions: the liquid level of the clear water tank is higher than the lower limit of the target liquid level at the current time, the predicted liquid level at the next target time is higher than the lower limit of the target liquid level at the target time, and the pressure difference before and after the valve of the control flow station is higher than the effective pressure difference.

[0166] 3.4.2 The control flow station with the largest pressure difference before and after the valve is selected to be operated. In this embodiment, if the control flow station is operated by A and B double valves, the flow regulating valve with the smallest opening degree is selected to be operated first, and the valves are alternately scheduled. The default adjustment opening degree of the valve is 10 degrees each time for single valve operation, and the default adjustment opening degree of the valve is 15 degrees each time for double valve operation.

[0167] 4. When the pressurizing station is in the water discharge stage and the pressure of the main control point of the pipe network exceeds the upper limit, the specific process is as shown in Figure 6 , and the following steps are performed:

[0168] 4.1 It is judged whether the pressurizing station and the pump pressure water plant are completely closed. Specifically, it is first judged whether the pressurizing station or the pump pressure water plant satisfies that the number of pumps operated for water discharge is 0 or the water flow is less than 100 m 3 / h.

[0169] 4.2 If it is judged that any of the conditions in 4.1 is satisfied, i.e., the pressurizing station or the pump pressure water plant is in a completely closed state, the water flow of the gravity flow water plant with the largest load is selected to be reduced. Specifically, the control flow station with the smallest pressure difference before and after the valve in the gravity flow water plant with the largest water discharge load is selected to be operated. In this embodiment, if the control flow station is operated by A and B double valves, the flow regulating valve with the larger opening degree is selected to be operated first, and the valves are alternately scheduled. The default adjustment opening degree of the valve is 10 degrees each time for single valve operation, and the default adjustment opening degree of the valve is 15 degrees each time for double valve operation.

[0170] 4.3 If it is judged that any of the conditions in 4.1 is not satisfied, i.e., the pressurizing station or the pump pressure water plant is not in a completely closed state, the water flow of the pump pressure water plant or the pressurizing station is selected to be reduced. Specifically, it is first judged whether the pressurizing station is operated for water discharge.

[0171] 4.3.1 If it is judged that the number of pumping stations open is greater than 0 or the water outflow is greater than 100 m 3 / h, that is, the pumping station is in the water outflow state, the water outflow of the operable pumping station is selected to be reduced. Specifically, among the pumping stations that can reduce water outflow, the pumping station with the smallest water supply time is selected to be closed. In this embodiment, the operable pumping station refers to the pumping station with a predicted liquid level difference greater than 0, and the predicted liquid level difference is calculated as target time predicted liquid level difference = current liquid level - current water outflow * (target time - current time) / clean water tank bottom area - target time target liquid level. The water supply time is calculated by the water outflow after the pumping station is stopped, and the specific calculation method is water supply time = (current liquid level - target time target liquid level) * clean water tank volume per meter / (current water outflow - rated flow of the pump to be stopped).

[0172] 4.3.2 If it is judged that the pumping station is not in the water outflow state, the water outflow of the pump pressure water plant is selected to be reduced. Specifically, the pump pressure water plant with the largest water outflow load is preferentially selected to be stopped. In this embodiment, small pumps are preferentially stopped (if any), and then large pumps are stopped until the water outflow load of the pump pressure water plant is 0.

[0173] In this embodiment, if it is judged every 3 minutes that, under the current state, the clean water tank liquid level of the gravity flow water plant is lower than the lower limit of its preset target liquid level, or the predicted liquid level is lower than the lower limit of the target liquid level according to the current clean water tank liquid level descending speed at the target time, the opening degree of the flow regulating valve of the corresponding flow control station of the gravity flow water plant is selected to be reduced until the clean water tank liquid level is higher than the preset minimum running liquid level of the corresponding period. If the flow control station is a double-valve A, B operation, the flow regulating valve with a larger valve opening degree is selected to be closed first, and the valves are alternately scheduled. The default adjustment opening degree of the valve in single-valve operation is 10 degrees each time, and the default adjustment opening degree of the valve in double-valve operation is 15 degrees each time. The specific flow chart is shown in Figure 7 .

[0174] In this embodiment, if it is judged every 3 minutes that, under the current state, the clean water tank liquid level of the gravity flow water plant is higher than the upper limit of its preset target liquid level, or the predicted liquid level is higher than the upper limit of the target liquid level at the target time, the water outflow of the pump pressure water plant is selected to be reduced. Specifically, the pump pressure water plant with the largest water outflow load is preferentially selected to be stopped. In this embodiment, small pumps are preferentially closed, and if there are no small pumps, large pumps are closed. The specific flow chart is shown in Figure 6 .

[0175] In this embodiment, if it is found that, under the current state, the clean water tank liquid level of the gravity flow water plant is higher than the highest running liquid level, and the water outflow load of the pump pressure water plant is greater than 0 or the water outflow is greater than 100 m 3 / h, the water outflow pump of the pump pressure water plant with the largest water outflow load is selected to be reduced, and large pumps are preferentially stopped. If there are no large pumps, small pumps can be stopped. The specific flow chart is shown in Figure 7 .

[0176] In this embodiment, the dispatchable object real-time information contains important abnormal information, such as abnormal raw water quality of the gravity flow water plant, the shortest time required for all dispatchable objects to reach the highest operating liquid level of the clear water tank is calculated, and the water plant and the booster station water outflow are reduced in reference to the step of the main control point pressure exceeding the upper limit in the booster station water inflow stage or the booster station water outflow stage, so as to quickly raise the liquid level of the clear water tank, which will not be described here.
