The specific pretreatment process is as follows:
fig. 3 is an exemplary schematic diagram of converting water supply and return temperature, pipe network flow and pipe network pressure in a pipe network into a three-dimensional structure, fig. 4 is an exemplary schematic diagram of adding valve opening, water pump operating parameters, a fitting curve of water pump operating frequency and pipe network flow, a fitting curve of water pump operating frequency and pipe network temperature difference, and a fitting curve of water pump operating frequency and pipe network pressure as hydraulic characteristics to the three-dimensional structure to form the pipe network operating parameters, according to the method shown in fig. 3, the pipe network flow (i.e. the flow value shown in fig. 3), the pipe network pressure (i.e. the pressure value shown in fig. 3) and the water supply and return temperature (i.e. the temperature value shown in fig. 3) in the pipe network are converted into the three-dimensional structure according to three elements of time, number of node layers and correlation weight, the method comprises the steps of recording a flow value, a pressure value and a temperature value in a pipe network from three dimensions of time, the number of layers of nodes and an association weight, wherein the association weight can be calibrated in advance according to a topological structure of the pipe network, the association weight is normally distributed by taking a main node 1 as an original point, the time granularity can be 10 seconds, 1 minute is accumulated to serve as a data cluster, namely, the water supply and return temperature, the pipe network flow and the pipe network pressure are collected once every 10 seconds, and the collected water supply and return temperature, the pipe network flow and the pipe network pressure form a data cluster every 6 times of collection. Converting the temperature of supply and return water, the flow rate of the pipe network and the pressure of the pipe network into a three-dimensional structure as shown in figure 3; according to the method shown in fig. 4, a fitting curve of a valve opening, a water pump operation parameter, a water pump operation frequency and a pipe network flow, a fitting curve of a water pump operation frequency and a pipe network temperature difference, and a fitting curve of a water pump operation frequency and a pipe network pressure are added to the three-dimensional structure as hydraulic characteristics to obtain the pipe network operation parameter, and the change frequency of the parameters of the water pump operation frequency and the valve opening is low, so that the time granularity can be set to be longer, for example, the time granularity is 5 minutes, namely, the water pump frequency and the valve opening are acquired once in 5 minutes, and since the acquisition frequency of the water pump frequency and the valve opening is 5 minutes, 5 containing data clusters can be used as a data subset, so that the water supply and return temperature, the pipe network flow and the pipe network pressure acquired every 5 minutes can correspond to the parameters (the water pump frequency and the valve opening) acquired once in 5 minutes. The preprocessed pipe network operation parameters shown in fig. 4 are obtained in this way, that is, after the pipe network operation parameters shown in fig. 4 are formed, the pipe network operation parameters can be input into the offline tuning model as input data, and the standard data which is easier to read by the offline tuning model is obtained by converting the supply and return water temperature, the pipe network flow rate and the pipe network pressure in the pipe network into a three-dimensional structure, and adding the valve opening, the water pump operation parameters, the fitting curve of the water pump operation frequency and the pipe network flow rate, the fitting curve of the water pump operation frequency and the pipe network temperature difference, and the fitting curve of the water pump operation frequency and the pipe network pressure into the three-dimensional structure as hydraulic characteristics.
And inputting the pipe network operation parameters into an offline optimization model to obtain the valve opening value and the water pump operation parameters under the condition that the pipe network water power meets the preset balance requirement.
Specifically, pipe network operation parameters including a valve opening value and water pump operation parameters are input into an offline optimization model; acquiring pipe network hydraulic balance information output by the offline tuning model, wherein the offline tuning model is used for acquiring the pipe network hydraulic balance information according to the pipe network target parameters; and judging whether the pipe network hydraulic balance information output by the offline tuning model is in a preset interval.
When judging whether the pipe network hydraulic balance information output by the offline tuning model is in a preset interval, acquiring dynamic hydraulic power failure scheduling of the pipe network and hydraulic balance degree of the pipe network output by the offline tuning model; the dynamic hydraulic power dispatching loss of the pipe network can be determined according to the following formula:
X＝QS/QJ；
wherein X is the dynamic hydraulic power failure scheduling of the pipe network, QS is the actual flow, and QJ is the design requirement flow.
The hydraulic balance degree of the pipe network can be determined according to the following formula:
r＝QJ/Qmax；
wherein r is the hydraulic balance degree of the pipe network, QJ is the flow required by the design, and Qmax is the maximum flow which actually appears.
Respectively judging whether the dynamic hydraulic power dispatching loss of the pipe network and the hydraulic power balance degree of the pipe network are both in a preset interval; when the dynamic hydraulic power failure rate of the pipe network and the hydraulic power balance degree of the pipe network are both in a preset interval, determining that pipe network hydraulic power balance information output by the offline tuning model is in the preset interval; and when at least one of the dynamic hydraulic power dispatching loss of the pipe network and the hydraulic power balance degree of the pipe network is not in a preset interval, determining that the pipe network hydraulic power balance information output by the offline dispatching and optimizing model is not in the preset interval. Specifically, the preset interval corresponding to the dynamic hydraulic power failure rate may be [95%,99% ]. That is, if X is less than 95%, it indicates that the dynamic hydraulic power failure rate is not within the corresponding preset interval. The preset interval corresponding to the hydraulic balance degree of the pipe network can also be [95%,99% ]. That is, if r is less than 95%, it indicates that the dynamic hydraulic balance is not within the corresponding preset interval.
And when the hydraulic balance information is in a preset interval, determining the valve opening value and the water pump operation parameter in the current pipe network operation parameters as the valve opening value and the water pump operation parameter under the condition of meeting the preset balance requirement.
When the hydraulic balance information is not in a preset interval, under the condition that other target parameters except the valve opening value and the water pump operation parameter are not changed, updating the valve opening value and the water pump operation parameter in the target parameters and continuously inputting the values into the offline tuning model to obtain the hydraulic balance information output by the offline tuning model until the hydraulic balance information output by the offline tuning model is in the preset interval; and determining the valve opening value and the water pump operating parameter when the hydraulic balance information output by the off-line tuning and optimizing model is in a preset interval as the valve opening value and the water pump operating parameter under the condition of meeting the preset balance requirement.
And adjusting the valve and the water pump according to the valve opening value and the water pump operation parameters under the condition that the hydraulic power of the pipe network meets the preset balance requirement.
A plurality of flow sensors and pressure sensors can be arranged in the pipeline network, and particularly, one flow sensor and one pressure sensor can be arranged in each pipeline, so that accurate flow values and pressure values in each pipeline can be obtained.
In addition, because the number of pipelines forming the pipe network is large, the method for arranging the sensors on each pipeline to carry out measurement has high test cost, the sensors with large number also need to be maintained and overhauled, and the method is huge workload, so that the test working efficiency is low. Therefore, in the present application, a limited number of flow sensors and pressure sensors may be sparsely arranged in the pipe network, and when the water pump frequency and the valve opening are fixed, the flow measured values and the pressure measured values in some specific pipes may be obtained through the limited number of flow sensors and pressure sensors, and then the impedance values of each pipe in the pipe network are identified according to the following steps 1 to 13:
step 1, setting an initial impedance value of a pipeline, and calculating the corresponding pipeline flow by adopting a basic loop method;
step 2, increasing the impedance value of a certain pipeline by a certain multiple (for example, increasing the impedance value to 5 times), calculating the corresponding pipeline flow at the moment by adopting a basic loop method, comparing the calculated pipeline flow with the initially calculated pipeline flow, and obtaining a comparison value of the impedance value of the pipeline with the flow change of other pipelines;
and 3, calculating each pipeline in the step 2 to obtain a contrast value of the impedance change of each pipeline to the flow change of other pipelines. Corresponding to a particular pipe a, the order of the other pipes that affect the flow of that pipe can be derived from the magnitude of the comparison. I.e. the impedance of the preceding pipe in the sequence, the greater the influence on the flow in pipe a. Summarizing and counting the data to obtain a (n-1) x (n-1) pipeline flow influence matrix;
step 4, according to step 2 and step 3, a (n-1) × (n-1) pipeline pressure influence matrix can be obtained. The pressure may be the inlet pressure or the outlet pressure of the conduit; the flow influence matrix comprises elements of a flow influence matrix, a pressure influence matrix and a network, wherein the elements of the flow influence matrix are the contrast value of the flow of a first specific pipeline when the impedance of each pipeline changes, the elements of the pressure influence matrix are the contrast value of the pressure of the first specific pipeline when the impedance of each pipeline changes, and the elements in the flow influence matrix and the elements in the pressure influence matrix are sequentially arranged according to the serial numbers of the pipelines in the network.
Step 5, corresponding to a specific certain actually measured working condition C, adopting the pipeline design impedance to carry out basic loop valve calculation to obtain the flow and pressure of the pipeline under the working condition;
step 6, corresponding to the working condition C, comparing the measured values of the pressure or flow measuring points arranged under the working condition with the calculated values in the step 5 to obtain corresponding absolute deviation and relative deviation of the pipelines;
and 7, according to the relative deviation obtained in the step 6, if the pipeline D is provided with measuring points and the relative deviation does not reach the precision range, adjusting the impedance of other pipelines according to the absolute deviation of the pipeline and the contrast value in the influence matrix of the pipeline, wherein the adjustment operation is to increase or reduce a certain numerical value, the absolute value of each adjustment is called a step length, and the positive and negative directions are called directions. The step size may be a fixed value or a variable value. The content of the adjustment method is mainly the direction. The adjusting method comprises the following steps: 1. the contrast value is positive, the absolute deviation is positive: the direction is positive; 2. when the contrast value is positive and the absolute deviation is negative: the direction is negative; 3. the contrast value is negative and the absolute deviation is positive: the direction is negative; 4. when the contrast value is negative and the absolute deviation is negative: the direction is positive; if the relative deviation of the pipeline D reaches the precision range, the pipeline does not need to be adjusted;
and 8, performing the operation of the step 7 on each pipeline with the measuring points, and adjusting the impedance value of each pipeline in the pipelines. If the impedance of a certain pipe is known, no adjustment is needed;
step 9, calculating the adjusted impedance value by a basic loop method to obtain corresponding flow and pressure distribution;
and 10, replacing the flow pressure in the step 5 with the flow pressure in the step 9, and repeating the steps 6, 7, 8 and 9 until the relative deviation of each pressure and each flow measurement point is within the precision allowable range. This condition is referred to as computational convergence under condition C;
