[0002] Many water conservancy projects take into account multiple functions such as power generation and water diversion (flood discharge). The water-passing structures of this type of water conservancy hub include two types of buildings: the unit and the water diversion gate (also known as the flood discharge gate), both of which discharge flow.

[0003] Since the downstream water levels of the two types of buildings are linked to each other when the flow passes through, it is difficult to coordinate to meet the water diversion requirements and generate sufficient power.

[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0031] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0032] In the past, there was no accurate flow measurement and control system for the flow rate of the power station and the water diversion gate. The flow rate was closely related to the downstream water level. Since the downstream water levels of the two types of buildings were linked to each other when the flow was combined, it was difficult to coordinate to meet the water diversion requirements and generate sufficient power. Therefore, the power station and the water diversion gate currently do not have accurate control of the water flow, let alone automatic adjustment functions.

[0033] The embodiment of the present application proposes a reasonable and refined linkage dispatching method for the flow of hub power station units and water diversion gates, which realizes adaptive regulation of water delivery flow and automatic dispatching in emergency situations, and maximizes the output of power station units while ensuring that the downstream flow meets the dispatching requirements.

[0034] Specifically, the present application embodiment will be described from the perspective of the dispatching device of the power generation and water diversion hub, and the dispatching device of the power generation and water diversion hub can be specifically integrated in a computer device, that is, the dispatching method of the power generation and water diversion hub in the present application embodiment can be executed by a computer device, and optionally, the computer device can include: a terminal device. The terminal device can be various personal computers, laptops, smart phones, tablet computers, etc.

[0035] The dispatching method of the power generation and water diversion hub provided in the embodiment of the present application can be applied to Figure 1 The scheduling system of the power generation and water diversion hub shown in the figure can include a computer device 102 and a server 104. The computer device 102 can be a device including both receiving and transmitting hardware, that is, a device with receiving and transmitting hardware capable of performing two-way communication on a two-way communication link. The computer device 102 and the server 104 can perform two-way communication through a network.

[0036] Optionally, the server may be an independent server, or a server network or server cluster composed of servers, including but not limited to a computer, a network host, a single network server, a plurality of network server sets or a cloud server composed of multiple servers. The cloud server is composed of a large number of computers or network servers based on cloud computing.

[0037] The following is a detailed description in conjunction with the accompanying drawings. In the embodiments of the present application, the execution subject is a terminal device as an example. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments. Although the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in an order different from that shown in the accompanying drawings.

[0038] Please refer to Figure 2 The specific process of the dispatching method of the power generation and water diversion hub can be as follows: Step 201 to Step 204, wherein:

[0039] Step 201, obtaining the current upstream water level, current downstream water level and target flow of the power generation and water diversion hub.

[0040] Step 202 , taking the target flow rate as a condition, based on the current upstream water level and the current downstream water level, predict the upstream and downstream water level difference.

[0041] Step 203: If the upstream and downstream water level difference meets the preset range conditions, the unit is dispatched to flow.

[0042] Step 204: If the upstream and downstream water level difference does not meet the preset range conditions, the dispatching unit and the water diversion gate are jointly used for flow.

[0043] Assuming that there are n generators of the same model in the power generation and diversion hub, and the diversion gate has m gates of the same size, the dispatch of the power generation and diversion hub needs to calculate the output of the generator (hereinafter referred to as the unit) and the opening of each gate of the diversion gate based on the known current upstream water level and the current downstream water level under the condition of target flow.

[0044] Specifically, the computer equipment collects the current upstream water level , Current downstream water level , and obtain the preset target flow , and calculate the target flow Predicted downstream water level under , the predicted downstream water level It can be used as the tail water level of the unit and the water level behind the energy dissipation pool downstream of the diversion gate.

[0045] The computer equipment then calculates the current upstream water level. and predict downstream water levels , calculate the water level difference between upstream and downstream. The water level difference between upstream and downstream refers to the height difference between water levels. Once the water level difference between upstream and downstream is large, it is easy to cause floods downstream.

[0046] For example, the upstream and downstream water level difference can be calculated by the following formula (1):

[0047] (1)

[0048] in, The difference in water level between upstream and downstream.

[0049] Next, the computer equipment determines whether the unit is generating electricity. If the upstream and downstream water level difference is within the head range of the unit's normal operation, the unit is dispatched to generate electricity and the unit participates in the operation dispatch; conversely, if the upstream and downstream water level difference is not within the head range of the unit's normal operation, the unit does not generate electricity, and all water diversion flows in the hub are discharged from the diversion gate.

[0050] Therefore, the computer equipment determines whether the upstream and downstream water level difference meets the preset range conditions. If so, it means that the upstream and downstream water level difference is within the head range of normal operation of the unit, and the unit is dispatched to pass the flow; conversely, if the upstream and downstream water level difference does not meet the preset range conditions, if the unit's flow rate is too large, it will cause the unit to vibrate, affecting the stability and life of the equipment, and there will be safety risks. Therefore, at this time, it is necessary to jointly dispatch the unit and the water diversion gate to prevent the unit from operating in the vibration range.

[0051] The scheduling method of the power generation and water diversion hub provided in the embodiment of the present application obtains the current upstream water level, the current downstream water level and the target flow of the power generation and water diversion hub, and takes the target flow as a condition, based on the current upstream water level and the current downstream water level, predicts the upstream and downstream water level difference, thereby judging whether the unit is generating electricity based on the upstream and downstream water level difference, and if the upstream and downstream water level difference meets the preset range conditions, the unit is scheduled to flow, and vice versa, if the upstream and downstream water level difference does not meet the preset range conditions, the unit and the water diversion gate are jointly scheduled to flow. Thus, the automatic multi-dimensional decision-making and adjustment of the flow of the unit and the water diversion gate of the power generation and water diversion hub is realized, which can ensure the normal operation of the generator set and maximize the power generation efficiency under the premise of ensuring that the downstream flow meets the water scheduling requirements.

[0052] The flow rate of the unit will be restricted in two aspects during normal operation. On the one hand, the unit is limited by the maximum output. On the other hand, in order to avoid the unit working in the vibration range, the flow rate of the unit is limited by the output limit line.

[0053] Therefore, if Figure 3 As shown, in some embodiments, if the upstream and downstream water level difference does not meet the preset range conditions, the dispatching unit and the water diversion gate jointly flow, including the following steps S301 to S304:

[0054] Step S301, if the upstream and downstream water level difference is greater than the first threshold, the unit output is determined based on the target flow rate;

[0055] Step S302, if the unit output does not exceed the maximum output, all units are dispatched to overcurrent;

[0056] Step S303, if the unit output is greater than the maximum output, determine the flow rate of each unit according to the maximum output, and dispatch the flow rate of each unit according to the flow rate of each unit; wherein the sum of the flow rate of each unit is the total flow rate;

[0057] Step S304, determining the diversion gate flow rate according to the total flow rate through the machine, and scheduling the diversion gate flow according to the diversion gate flow rate.

[0058] When the upstream and downstream water level difference is higher than a certain value, the excessive flow rate of the unit may cause the unit to vibrate, so the unit will be limited by the output limit line; when the upstream and downstream water level difference is lower than a certain value, the unit will not be limited by the output limit line, and its flow rate will only be limited by the maximum output. The first threshold value can be greater than or equal to the maximum value in the preset range indicated by the preset range condition.

[0059] Specifically, the computer device determines whether the unit is subject to output restriction, and decides how to dispatch the unit's output. The computer device determines a first threshold, and compares the upstream and downstream water level difference with the first threshold. The first threshold may be a preset value.

[0060] If the upstream and downstream water level difference is greater than the first threshold, the computer device determines the unit output based on the target flow rate. N , and the output N With maximum output For comparison, the maximum output is the rated value.

[0061] like , indicating that the flow rate of the unit can meet the water diversion flow requirements, then the computer equipment dispatches all units to output, the water diversion flow all passes through the unit, the water diversion gate does not divert water, and the normal dispatching process is completed. Among them, the output of each unit is ; When there are n units, the n units have equal output.

[0062] For example, the relationship between the unit output N and the flow rate satisfies the following formula (2):

[0063] (2)

[0064] in, is the density of water, g is the acceleration due to gravity, is the upstream and downstream water level difference, For the flow rate, is the unit operating efficiency. The unit operating efficiency is obtained through a pre-established efficiency curve fitting model. The efficiency curve fitting model takes unit flow and unit head as independent variables, unit operating efficiency as dependent variable, constructs a binary quadratic polynomial fitting function, and estimates the parameters through the least squares method to obtain the solution.

[0065] And if , indicating that the target flow exceeds the limit of the unit's flow. In order to ensure the safe operation of the unit, the unit output needs to be limited, that is, the output of each unit is determined according to the maximum output. In the extreme case, the output of each unit is the maximum output, that is, The computer equipment can calculate the flow rate of each unit based on the maximum output of the unit. , and then, the computer equipment dispatches each unit to operate according to the flow rate.

[0066] Computer equipment calculates the flow rate of each unit The total flow rate is obtained by adding , based on the total machine flow The flow rate that needs to be diverted by the water diversion gate can be determined, that is, the water diversion gate flow rate .

[0067] For example, the flow rate of the water diversion gate can be calculated by the following formula (3):

[0068] (3)

[0069] Thus, the computer equipment can schedule the flow of the water diversion gate according to the flow of the water diversion gate, including controlling the opening and closing of the water diversion gate, the opening of one or more gates of the water diversion gate, etc.

[0070] In the above embodiment, when the upstream and downstream water level difference does not meet the preset range conditions, it is determined whether the upstream and downstream water level difference is greater than the first threshold value, thereby determining whether the flow rate passing through the unit may be too large to cause potential risks of unit vibration, and determining the unit output, so as to dispatch the unit to pass the flow alone or to divert water in conjunction with the water diversion gate, thereby ensuring the safe operation of the unit and ensuring that it is subject to the output limit line.

[0071] If the upstream and downstream water level difference is less than the second threshold, then Figure 4 As shown, in some embodiments, the dispatching unit and the water diversion gate jointly flow through, including the following steps S401 to S405:

[0072] Step S401, determining the maximum allowable flow rate of each unit;

[0073] Step S402, determining the maximum allowable total flow rate according to the maximum allowable flow rate of each unit;

[0074] Step S403, if the maximum allowable total flow rate is greater than the target flow rate, all units are scheduled to flow;

[0075] Step S404, if the maximum allowable total flow rate is less than the target flow rate, dispatch the flow rate of each unit according to the maximum allowable total flow rate;

[0076] Step S405, determining the diversion gate flow rate according to the maximum allowable total flow rate through the machine, and scheduling the diversion gate flow according to the diversion gate flow rate.

[0077] Specifically, if the upstream and downstream water level difference If the value is less than the second threshold, it means that the flow rate of the unit is limited by the output limit line to prevent the unit from operating in the vibration range, which may pose a safety hazard. Therefore, the computer equipment determines the maximum allowable flow rate of each unit. The second threshold may be less than or equal to the minimum value in the preset range indicated by the preset range condition.

[0078] According to the maximum allowable flow rate of each unit , the computer equipment determines the maximum allowable total flow rate, which is the sum of the maximum allowable flow rates of each unit. .

[0079] The computer equipment will set the maximum allowable total machine flow With target flow For comparison, if , indicating that the target flow can all pass through the unit. At this time, the computer equipment can calculate the flow rate of each unit among the n units by the following formula (4):

[0080] (4)

[0081] The computer equipment can then calculate the unit output based on the flow rate of each unit and the above formula (2). The output of each unit is ; When there are n units, the n units are equal in output. At this time, the water diversion gate does not divert water, and the normal dispatching process is completed.

[0082] And if , indicating that the target flow requires the joint dispatch of the unit and the diversion gate. In order to ensure the safe operation of the unit, the computer equipment determines the flow rate of each unit according to the maximum allowable total flow rate, that is, The computer equipment can further calculate the output of each unit based on the flow rate of each unit. , and control the unit to pass current accordingly. When there are n units, the n units have equal output.

[0083] Then, the computer device can determine the flow rate required for the water diversion gate to divert water based on the maximum allowable total flow rate, that is, the water diversion gate flow rate. At this time, the calculation of the water diversion gate flow rate can be calculated by referring to formula (3).

[0084] Thus, the computer equipment can schedule the flow of the water diversion gate according to the flow of the water diversion gate, including controlling the opening and closing of the water diversion gate, the opening of one or more gates of the water diversion gate, etc.

[0085] In the above embodiment, when the upstream and downstream water level difference does not meet the preset range conditions, it is determined whether the upstream and downstream water level difference is less than the second threshold value, thereby determining whether the unit is at potential risk of operating in the vibration range, ensuring that it is subject to the output limit line, and thereby dispatching the unit to conduct a single flow or to divert water in conjunction with the water diversion gate, thereby ensuring the safe operation of the unit.

[0086] In some embodiments, scheduling the flow of the water diversion gate according to the water diversion gate flow rate includes: determining available water diversion gates according to the maintenance information of the water diversion gate; and scheduling the flow of each available water diversion gate according to the maintenance information of the water diversion gate and the water diversion gate flow rate.

[0087] Specifically, the computer device obtains the maintenance information of the water diversion gate, determines whether the water diversion gate is under maintenance, and determines the available water diversion gates accordingly. If the water diversion gate is not under maintenance and all water diversion gates are available, the computer device preferentially opens all gates evenly to divert water. If a water diversion gate is under maintenance, that is, in maintenance, the computer device opens the available water diversion gates to divert water.

[0088] In the above embodiment, the gate of the water diversion gate is controlled to divert water through the inspection information of the water diversion gate, ensuring that each water diversion gate meets both the safety inspection conditions and the scheduling principles, and ensuring the structural safety of the gate.

[0089] Among them, according to the maintenance information of the water diversion gate and the flow of the water diversion gate, the available water diversion gates are dispatched to pass the flow, including: when the water diversion gate is not under maintenance, the gates of the water diversion gate are opened evenly to pass the flow; when one gate of the water diversion gate is under maintenance, the remaining gates are opened to pass the flow; among them, when the gates of the water diversion gate are opened evenly, the gate openings of each gate are the same.

[0090] Specifically, when the water diversion gate is not under maintenance, the computer device evenly opens the gates of the water diversion gate to divert water. Since the gate is prone to flow-induced vibration when operating at a small opening, which is not conducive to the safety of the gate structure, the computer device can control the opening of the water diversion gate to a preset value, such as not less than 20 cm. When one gate of the water diversion gate is under maintenance, the remaining gates are opened to allow flow.

[0091] Taking the actual scheduling principle as an example, among the three gates of the water diversion gate, only one is allowed to be under maintenance during the same period of time. Accordingly, the computer equipment determines whether one water diversion gate is under maintenance; if one water diversion gate is under maintenance, the other two water diversion gates are opened to replenish water.

[0092] In the above embodiment, by controlling the water diversion of each gate, adaptive adjustment of the water diversion gate flow is achieved, which can ensure the normal operation of the generator set under the premise of ensuring that the downstream flow meets the water volume scheduling requirements.

[0093] In actual operation, there may be a sudden failure such as the water diversion gate starting up automatically. When the water diversion gate suddenly fails, the above method also includes: giving an alarm through an alarm device and switching to manual operation. The manual operation scheduling scheme is consistent with the water diversion scheduling scheme process for the power generation hub provided in the embodiment of the present application.

[0094] like Figure 5 As shown, in some embodiments, the method further includes the following steps S501 to S504:

[0095] Step S501, when the preset time is reached after scheduling, the real-time upstream water level, real-time downstream water level and real-time average flow are collected;

[0096] Step S502, determining the deviation between the real-time average flow and the target flow;

[0097] Step S503: if the deviation is less than the third threshold, the scheduling is terminated;

[0098] Step S504: If the deviation is not less than the third threshold, a new target flow is re-determined according to the target flow and the deviation, and scheduling is restarted according to the new target flow.

[0099] Specifically, during normal scheduling, the computer device can start the feedback program after the preset time, such as 1 hour, 2 hours, etc., is reached after scheduling. , real-time downstream water level and real-time average flow Among them, the real-time average flow The average value of real-time traffic within a certain period of time after the scheduling is completed can be taken.

[0100] Computer equipment calculates current flow and target traffic The deviation between them can be calculated by the following formula (5):

[0101] (5)

[0102] in, is the deviation between the real-time average flow and the target flow.

[0103] Then, the computer device determines the relative value of the deviation Is it within 1%?

[0104] If the computer device determines , the feedback adjustment process ends; and if the computer device determines , then a new target flow rate is re-determined based on the target flow rate and deviation, as shown in the following formula (6):

[0105] (6)

[0106] Therefore, the computer device re-executes the scheduling process based on the new target flow, that is, the input value step S201 is re-executed.

[0107] In the above embodiment, the dispatching process and results are monitored in real time through flow feedback adjustment to ensure that the dispatching meets actual needs, and can make timely adjustments to the automated dispatching when the actual situation changes or unexpected situations occur, effectively ensuring the safe operation and intelligent dispatching of the power generation and water diversion hub.

[0108] Among them, Figure 6 As shown, in some embodiments, taking the target flow rate as a condition, based on the current upstream water level and the current downstream water level, predicting the upstream and downstream water level difference includes steps S601 to S604:

[0109] Step S601, obtaining historical upstream water level, historical downstream water level and historical water transfer flow;

[0110] Step S602, generating a water level-flow relationship curve based on historical upstream water levels, historical downstream water levels and historical water transfer flows;

[0111] Step S603, predicting the water level-flow relationship curve based on the current upstream water level, the current downstream water level and the target flow, to obtain a predicted downstream water level;

[0112] Step S604, determining the upstream and downstream water level difference based on the current upstream water level and the predicted downstream water level.

[0113] Specifically, the computer device obtains the historical upstream water level, the historical downstream water level and the historical water transfer flow, and performs fitting based on the historical upstream water level, the historical downstream water level and the historical water transfer flow, thereby generating a water level-flow relationship curve. For example, Figure 7 As shown in the figure, the relationship between the water level and flow rate of a hub control section can be fitted into a curve. Therefore, the computer equipment can make predictions based on the water level and flow rate relationship curve generated by the fitting, and substitute the current upstream water level, the current downstream water level and the target flow rate into the water level and flow rate relationship curve to deduce the downstream water level after the water flow rate changes, that is, predict the downstream water level.

[0114] Furthermore, the computer equipment can calculate the upstream and downstream water level difference based on the current upstream water level and the predicted downstream water level.

[0115] In the above embodiment, a water level-flow relationship curve is generated by fitting historical data, and the predicted downstream water level is obtained by combining the currently collected data, so that the calculation of the upstream and downstream water level difference is accurate and consistent with the actual change trend, thereby improving the accuracy of scheduling.

[0116] In a specific embodiment, please refer to Figure 8 The scheduling method for the power generation and water diversion hub provided in the embodiment of the present application may include a normal scheduling module and a flow feedback adjustment module. The normal scheduling module includes the following steps:

[0117] Step S801: Collect the current upstream water level , downstream water level , and obtain the target traffic ;

[0129] Step S8013: actual output of computer group , and end the normal scheduling process;

[0130] Step S8014, determine the flow rate of each unit, that is, ;

[0132] Step S8016, determine the flow rate of the water diversion gate ;

[0133] Step S8017, determine whether the water diversion gate is under maintenance; if so, execute step S8018, otherwise execute step S8019;

[0134] Step S8018, assuming that the actual scenario is a water diversion gate with m holes of the same size, and there are x holes of water diversion gates under maintenance, then the opening of the mx holes of water diversion gates is calculated, where the mx holes of the gates are of the same height, and the normal scheduling process ends;
