Description

Technical Field

[0001] The present application relates to the technical field of heat supply management, and in particular to a heat supply balance control management system and method. Background Art

[0002] According to statistics, in the entire heating system, electricity consumption of equipment accounts for more than 20% of the total energy consumption, and the operating conditions of the pipeline network directly affect the transmission and distribution of fluids.

[0003] Most of the existing heating network transmission and distribution systems use a single water pump to bear the transmission and distribution power of the entire system. A main pump is used to meet the flow demand of the network and overcome the operating resistance of all pipelines. Since this form cannot predict the subsequent system expansion needs in the early stage of application, with the continuous extension of the heating network, on the one hand, it is inevitable that there will be problems such as insufficient water pump output or high electricity consumption caused by excessive installation of water pumps in the early stage. On the other hand, there is the phenomenon of repeated investment or large initial investment caused by water pump replacement. In addition, there is also the problem of being unable to save energy through operation adjustment. Summary of the invention

[0004] In order to solve the above technical problems, an embodiment of the present application provides a heat balance control management system, which is used to control the heat balance of a pipe network distribution system, wherein the pipe network distribution system includes a heat source, a heat source water supply pump, a heat source return water pump, and a plurality of distribution modules; each of the distribution modules is connected in parallel to the heat source, including a distribution water supply pump and at least one heat-using partition, the heat-using partition includes a heat exchanger and a partition return water pump, wherein the inlet and outlet of the partition return water pump are respectively connected to the outlet of the heat exchanger and the return water port of the heat source, and each of the heat-using partitions is connected in parallel to the distribution water supply pump; the management system includes a plurality of heat data collectors, an energy consumption information collector, a heat source water supply regulator, a distribution water supply regulator, a partition return water regulator, and a balance control component; wherein the plurality of heat data collectors are arranged corresponding to the heat source water supply pump and the distribution water supply pump, and are used to collect the water supply heat value of the corresponding water supply pump and send it to the balance control component; the energy consumption information collector is used to obtain The energy consumption information of each water pump in the pipe network distribution system is obtained and sent to the balancing and control component; the balancing and control component is used to calculate the total power-to-heat ratio of the pipe network distribution system and the module power-to-heat ratio of each distribution module based on the water supply calorific value and the energy consumption information, and for the distribution module whose module power-to-heat ratio is greater than the total power-to-heat ratio, determine the first target control parameter of each partition return water regulator, and send it to the partition return water regulator; the partition return water regulator is used to adjust the partition return water pump in real time based on the first temperature threshold and the second temperature threshold, and send a synchronous adjustment instruction to the distribution and supply water regulator corresponding to the distribution module when adjusting the partition return water pump; it is also used to update the first temperature threshold and the second temperature threshold based on the first target control parameter after receiving the first target control parameter; the distribution and supply water regulator is used to synchronously adjust the distribution and supply water pump when receiving the synchronous adjustment instruction.

[0005] Based on the above technical solution, firstly, a pipe network distribution system based on a multi-stage pump is provided, and water supply and return water control pumps are respectively set for different heat consumption zones, providing a basis for independent control of each heat consumption zone. At the same time, the distribution energy efficiency of each distribution module of the system is monitored through the balancing and control component, and the distribution modules with insufficient distribution energy efficiency are adjusted in time to maintain the distribution energy efficiency of each distribution module higher than the total distribution energy efficiency, providing a basis for flexibly responding to changes in users' heat demand.

[0006] In addition, when the module transmission and distribution energy efficiency does not meet the requirements, the balancing control component only needs to send the first target control parameter to the partition return water regulator to update the control parameters of the partition return water regulator, so that the partition return water regulator can adjust the partition return water pump according to the real-time secondary supply and return water temperature, so as to meet the user's heating needs by changing the flow in the heat zone, thereby reducing the adjustment frequency. At the same time, when adjusting the partition return water pump, the partition return water regulator can also send a synchronous adjustment instruction to the transmission and distribution water supply regulator, so that the transmission and distribution water supply regulator can follow the synchronous adjustment of the transmission and distribution water supply pump to assist in the flow adjustment in the heat zone, maintain stable operation in the zone, and improve the energy efficiency of the transmission and distribution module. In this way, by monitoring and managing the distribution energy efficiency of the distribution modules, the power consumption to heat transmission ratio of each distribution module in the system can be maintained at a low level, thereby achieving the energy-saving goal. By synchronously mobilizing the auxiliary control of the distribution water supply pump, the pressure margin at the upstream end can be fully utilized to regulate the flow inside the module, reducing the output of the front-end control pump while meeting the demand, reducing the power load of the control pump, thereby achieving the effect of saving electricity and improving the distribution energy efficiency.

[0007] At the same time, each heat-using zone can be controlled independently and connected in parallel. Even if the pipeline distribution system needs to be expanded in the future, flexible expansion and unified control of the heat-using zones can be achieved.

[0008] In one implementation, the management system also includes a first temperature sensor and a second temperature sensor, which are respectively used to collect the secondary water supply temperature and the secondary return water temperature in the heat-using zone, and send them to the zone return water regulator; the zone return water regulator performs real-time adjustment of the zone return water pump based on the first temperature threshold and the second temperature threshold, including calculating the average temperature based on the secondary water supply temperature and the secondary return water temperature, and respectively judging the relationship between the average temperature and the first temperature threshold and the second temperature threshold, so as to determine the adjustment method for the zone return water pump.

[0009] Based on the above technical solution, the secondary water supply temperature and the secondary return water temperature in the heat zone are collected by the first temperature sensor and the second temperature sensor as the control data basis of the zone return water regulator. According to the average temperature change of the secondary supply and return water in the zone, the actual heat demand changes of the zone users can be perceived, and then corresponding adjustments can be made according to the actual demand changes, thereby avoiding excessive or insufficient heating.

[0010] In one embodiment, the balancing and regulating component is also used to send a second target control parameter to the distribution and water supply regulator, and the second target control parameter includes a preset duration, a target unit and a target variation range; the distribution and water supply regulator is also used to control the distribution and water supply pump to gradually modulate the frequency downward with the target unit amplitude when it is monitored that the outlet flow of the distribution and water supply pump is stable and continues for a preset duration, until the change in the outlet flow exceeds the target variation range, and then stop the downward adjustment.

[0011] Based on the above technical solution, each water distribution and supply regulator can further tap the energy-saving capability of the corresponding water distribution and supply pump, thereby saving system energy consumption.

[0012] In one implementation, the management system also includes a first pressure difference acquisition unit, which is arranged corresponding to the heat source water supply pump, and is used to collect the pressure difference between the inlet and outlet of the heat source water supply pump, and send it to the heat source water supply regulator; the heat source water supply regulator is used to calculate the target flow rate according to the pressure difference, and adjust the flow rate of the heat source water supply pump according to the target flow rate and the current flow rate value until the flow rate monitored by the heat data collector meets the target flow rate requirement.

[0013] Based on the above technical solution, the heat source water supply regulator only needs to adjust the flow rate according to the pressure difference on both sides of the heat source water supply pump to achieve timely adjustment of the total water supply flow rate, thereby providing the required flow rate for each distribution module. There is no need to pay attention to the control requirements of the distribution module, and the self-regulation ability of the system is fully utilized.

[0014] In one implementation, the management system also includes a heat source return water regulator and a second pressure difference collection unit. The second pressure difference collection unit is set corresponding to the heat source return water pump, and is used to collect the pressure difference between the inlet and outlet of the heat source return water pump and send it to the heat source return water regulator; the heat source return water regulator is used to adjust the heat source return water pump when it is monitored that the pressure difference exceeds a second preset balance range, so that the pressure difference monitored by the second pressure difference collection unit returns to the second preset balance range.

[0015] Based on the above technical solution, the heat source return water regulator can maintain the pressure stability of the distribution system and ensure the normal operation of the pipeline distribution system by monitoring the total return water data of the main pipeline and controlling the heat source return water pump accordingly.

[0016] In one implementation, the management system also includes a third pressure differential acquisition unit and a fourth pressure differential acquisition unit; the distribution and water supply regulator is used to monitor the module pressure differential of the distribution module in real time through the third pressure differential acquisition unit to determine whether the module pressure differential is abnormal, and when the module pressure differential is abnormal, enter the adjustment waiting mode to receive the synchronous control instruction sent by the partition return water regulator during the waiting period, and enter the synchronous adjustment mode upon receiving the synchronous control instruction; the partition return water regulator is used to monitor the partition pressure differential of the partition in real time through the fourth pressure differential acquisition unit to determine whether the partition pressure differential is abnormal, and when the partition pressure differential is abnormal, adjust the partition return water pump to return the partition pressure differential to the fourth preset balance range, and send the synchronous control instruction to the distribution and water supply regulator at the same time.

[0017] Based on the above technical solution, the operating status of each partition and module is determined by monitoring the pressure difference of the modules and partitions, and adjustments are made when the pressure difference is abnormal, thereby maintaining stable operation inside the module.

[0018] In one embodiment, the distribution and water supply regulator is also used to send a module abnormality notification to the balancing and control component if the synchronous control instruction is not received at the end of the waiting period or the module pressure difference is still abnormal when the synchronous adjustment is completed; the balancing and control component is also used to determine the pressure difference adjustment amplitude of each heat-using zone in the distribution module according to the heat demand corresponding to each heat-using zone in the distribution module after receiving the module abnormality notification, and determine the time to send the adjustment instruction to the return water regulating pump of each zone based on each pressure difference adjustment amplitude, so as to generate an adjustment strategy, and send the adjustment instruction to the return water regulating pump of each zone based on the scheduling strategy; wherein, the greater the heat demand, the greater the pressure difference adjustment amplitude, the earlier the sending time, and the sending time interval between two adjacent adjustment instructions is determined based on the difference between the pressure difference adjustment amplitudes of the two.

[0019] Based on the above technical solution, when a module abnormality is detected, the balancing and control components intervene to trigger each partition to actively share the module pressure difference regulation pressure. On the one hand, it helps to recover the module pressure difference abnormality as soon as possible, and on the other hand, it can avoid negative impacts on the normal operation of each partition as much as possible.

[0020] In one implementation, the distribution and water supply regulator is also used to enter the synchronous regulation mode after sending the module abnormality notification, and when monitoring that the module pressure difference has recovered to the third preset balance range, send a normal pressure difference notification to the balance regulation component; the balance regulation component is also used to stop sending regulation instructions after receiving the normal pressure difference notification sent by the distribution and water supply regulator.

[0021] Based on the above technical solution, the water supply regulator can actively perform synchronous adjustment when the module is abnormal, thereby assisting the pressure difference adjustment of each partition, realizing hierarchical linkage, and improving the regulation efficiency.

[0022] In addition, the present application also provides a heat balance regulation and management method, which is implemented based on the above-mentioned management system, wherein the method for the zone return water regulator to perform real-time regulation of the zone return water pump based on the first temperature threshold and the second temperature threshold includes: real-time acquisition of the secondary water supply temperature and the secondary return water temperature of the heat zone where the zone return water pump is located, and calculation of the average temperature; respectively judging the relationship between the average temperature and the first temperature threshold and the second temperature threshold, wherein the first temperature threshold is less than the second temperature threshold; when the average temperature is less than the first temperature threshold, regulating the zone return water pump to achieve flow acceleration; when the average temperature is greater than the second temperature threshold, regulating the zone return water pump to achieve flow reduction.

[0037] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0038] Please refer to Figure 1The heat balance control management system provided in the embodiment of the present application is used to Figure 1 The heat balance regulation and management of the pipeline distribution system shown.

[0039] like Figure 1 As shown, the pipe network distribution system 100 includes a heat source 11, a heat source distribution water supply pipe 111, a heat source distribution return pipe 112, a heat source supply pump 12, a heat source return pump 13, and two distribution modules 141 and 142, wherein the distribution module 141 includes only one heat partition, and the distribution module 142 includes two heat partitions. Each distribution module is connected to the heat source 11 in parallel, and each heat partition in the same distribution module is connected in parallel. It can be understood that in actual application, the number of distribution modules and heat partitions in the pipe network distribution system can be set according to actual needs, and the present application is not limited thereto.

[0040] The heat source 11 can be distributed or centralized, and is the heat source for the entire system. It supplies heat through a linkage method to meet the overall system demand.

[0041] The heat source water supply pump 12 is arranged at the heat supply outlet of the heat source 11, and is respectively connected to the heat source 11 and the heat source distribution water supply pipe 111, and is used to overcome the resistance of the heat source distribution water supply main pipeline and necessary facilities to provide the flow required for pipeline distribution.

[0042] The heat source return water pump 13 is arranged at the return water inlet of the heat source 11, and is respectively connected to the heat source 11 and the heat source distribution return water pipe 112, so as to overcome the internal resistance of the heat source distribution return water main pipeline and the heat source to provide the return water flow requirement required by the heat source 11.

[0043] The distribution module 141 includes a distribution water supply pump 1411 and a heat partition 1412. One end of the distribution water supply pump 1411 is connected to the heat source distribution water supply pipe 111, and the other end is connected to the heat partition 1412 to control the water supply flow of the distribution module 141.

[0044] The distribution module 141 provides heat exchange for the heat user unit through the heat partition 1412. The heat partition 1412 includes a heat exchanger 1412a and a partition return water pump 1412b, wherein the inlet of the heat exchanger 1412a is connected to the distribution water pump 1411, and the outlet is connected to the partition return water pump 1412b, which is used to perform heat exchange with the secondary water supply system, and then provide heat service to the user through the secondary water supply system to meet the user's heat demand.

[0045] The inlet of the zone return pump 1412b is connected to the outlet of the heat exchanger 1412a, and the outlet is connected to the heat source distribution return pipe 112, which is used to control the return pressure of the heat zone 1412, overcome the operating resistance within the zone, and meet the flow required by the heat exchanger 1412 for heat exchange.

[0046] The distribution module 142 includes a distribution water supply pump 1421 and two heat-using partitions 1422 . One end of the distribution water supply pump 1421 is connected to the heat source distribution water supply pipe 111 , and the other end is connected in parallel to each heat-using partition 1422 to control the water supply flow of the distribution module 142 .

[0047] The distribution module 142 provides heat exchange for the heat user unit through the heat partition 1422. The heat partition 1422 includes a heat exchanger 1422a and a partition return water pump 1422b, wherein the inlet of the heat exchanger 1422a is connected to the distribution water pump 1421, and the outlet is connected to the partition return water pump 1422b, which is used to perform heat exchange with the corresponding secondary water supply system, and then provide heat service to the user through the secondary water supply system to meet the user's heat demand.

[0048] The inlet of the zone return pump 1422b is connected to the outlet of the heat exchanger 1422a, and the outlet is connected to the heat source distribution return pipe 112 to achieve connection with the return port of the heat source 11, and is used to control the return pressure of the heat zone 1422, overcome the operation resistance in the zone, and meet the flow required by the heat exchanger 1422 for heat exchange. Among them, the two heat zones 1422 have the same structure and composition, and are not described separately.

[0049] Based on the above-mentioned pipeline distribution system 100, under the premise of unified supply of system heat source, joint control can be achieved through the heat source supply pump and the heat source return water pump on the heat source distribution supply and return pipe, so as to avoid large flow fluctuations caused by excessive adjustment range of a single water pump, thereby stabilizing system operation.

[0050] At the same time, based on the heat source transmission flow, the downstream distribution modules at all levels can adjust the flow through separately set module water supply pumps, and at the same time, use the pressure margin at the upstream end to adjust the flow inside the module; further, it can be combined with the power provided by the zone return pumps in each heat zone, so that under the premise of meeting the heat demand, the output of the front-end water supply pump can be reduced, and the power load of the water supply pump can be reduced, thereby achieving the effect of saving electricity and improving the energy efficiency of distribution.

[0051] In order to achieve effective control of each water pump in the pipe network transmission and distribution system 100, so as to achieve balanced regulation of the pipe network transmission and distribution system and improve the transmission and distribution energy efficiency of the pipe network. Figure 2 and Figure 3The embodiment of the present application provides a heat supply balance regulation and management system 200, including multiple heat data collectors 210, energy consumption information collectors 220, a first temperature sensor 231, a second temperature sensor 232, a first pressure difference collection unit 241, a second pressure difference collection unit 242, a third pressure difference collection unit 243, a fourth pressure difference collection unit 244, a heat source water supply regulator 251, a heat source return water regulator 252, a distribution water supply regulator 253, a partition return water regulator 254 and a balance regulation component 260.

[0052] The heat data collector 210 is installed in the pipe network distribution system, corresponding to the heat source water supply pump and the distribution water supply pump, and is used to collect the water supply heat value of each water supply pump and send it to the balance control component 260. In a specific example, the heat data collector is a calorimeter, such as Figure 3 The calorimeters 210a, 210b and 210c are shown in FIG.

[0053] The energy consumption information collector 220 is used to collect the energy consumption information of each water pump in real time and send it to the balance control component 260. In a specific example, the energy consumption information collector 220 can be an automatic meter reader installed corresponding to the on-site power metering equipment, wherein the power metering equipment is used to record the power consumption data of each water pump; the energy consumption information collector 220 can also be a collection program deployed in the power consumption system of each water pump, which is used to obtain the power consumption data of each water pump. Among them, the energy consumption information can be determined based on the power consumption data.

[0054] The first temperature sensor 231 is installed at the secondary water supply port of the heat zone to collect temperature information of the secondary water supply.

[0055] The second temperature sensor 232 is installed at the secondary return water inlet of the heat zone to collect temperature information of the secondary return water.

[0056] It can be understood that the secondary water supply inlet and the secondary water return inlet of each heat zone are correspondingly installed with a first temperature sensor and a second temperature sensor.

[0057] The first pressure difference acquisition unit 241 includes pressure sensors 241a and 241b installed at the inlet and outlet sides of the heat source water supply pump, which are used to collect the pressure values ​​at the inlet and outlet sides of the heat source water supply pump, and then obtain the pressure difference at the inlet and outlet sides of the heat source water supply pump.

[0058] The second pressure difference acquisition unit 242 includes pressure sensors 242a and 242b installed at the inlet and outlet sides of the heat source return pump, which are used to collect the pressure values ​​at the inlet and outlet sides of the heat source return pump, and then obtain the pressure difference at the inlet and outlet sides of the heat source return pump.

[0059] The third pressure difference acquisition unit 243 includes a pressure sensor 243a installed on the inlet side of the distribution water supply pump and a pressure sensor 243b installed on the outlet side of the distribution module, which is used to collect the pressure value on the inlet side of the distribution water supply pump and the pressure value on the outlet side of the distribution module, and then obtain the pressure difference between the inlet and outlet sides of the distribution module.

[0060] The fourth differential pressure acquisition unit 244 includes a pressure sensor 244a installed at the inlet side of the distribution water supply pump and a pressure sensor 244b installed at the outlet side of the zone return water pump, which is used to collect the pressure value at the inlet side of the distribution water supply pump and the pressure value at the outlet side of the zone return water pump, and then obtain the pressure difference at the inlet and outlet sides of the heat-using zone. It can be understood that the pressure sensor in the fourth differential pressure acquisition unit 244 can be a reuse of the same pressure sensor in the third differential pressure acquisition unit.

[0061] The heat source water supply regulator 251 is used to regulate the heat source water supply pump to control the opening of the inlet and outlet valves and the motor speed of the heat source water supply pump, thereby achieving flow regulation.

[0062] The heat source water supply regulator 252 is used to regulate the heat source return water pump to control the inlet and outlet valve openings and motor speed of the heat source water supply pump, thereby achieving flow regulation.

[0063] The water supply regulator 253 is used to regulate the water supply pump to control the opening of the inlet and outlet valves and the motor speed of the water supply pump, thereby achieving flow regulation.

[0064] The zone return water regulator 254 is used to regulate the zone return water pump to control the opening of the inlet and outlet valves and the motor speed of the zone return water pump, thereby achieving flow regulation.

[0065] Among them, each regulator is installed at the site of the corresponding controlled water pump. In one example, the regulator corresponds to the water pump one-to-one; in another example, the correspondence between the regulator and the water pump is one-to-many, that is, one regulator can regulate multiple water pumps respectively. The specific correspondence can be selected according to the equipment type of the regulator. When a regulator has the ability to independently control multiple water pumps, it is chosen to connect multiple water pumps at the same site to the same regulator.

[0066] In implementation, the regulator may be a PID (Proportional Integral Derivative) controller, or an edge server, or a wireless control terminal.

[0067] The balancing and regulating component 260 is used to set the control parameters of each regulator so that each regulator can adjust the corresponding water pump based on the received control parameters to achieve flow control.

[0068] The balancing and control component 260 is deployed in the background server. On the one hand, it can set basic control parameters for the regulator according to the basic operating requirements of the pipeline distribution system to maintain the minimum flow rate in the pipeline distribution system; on the other hand, it can generate dynamic control parameters according to the energy consumption during the operation of the management distribution system, and send them to the corresponding regulator, so that the operation of the pipeline distribution system can be dynamically adapted to the user's heat demand, so as to save system operation energy consumption.

[0069] Based on the above management system, it is possible to realize independent control of each water pump by monitoring the flow and pressure in the pipeline distribution system, and simultaneously realize multi-stage pump linkage and distributed regulation, so as to achieve the goal of energy saving in pipeline distribution and reduced consumption in operation.

[0070] To achieve multi-stage pump linkage and distributed control, please refer to Figure 4 The heat supply balance control method performed by the balance scheduling component in the management system provided in an embodiment of the present application includes the following steps: S401, based on the water supply calorific value and energy consumption information of each water supply pump, the total power consumption and heat transfer ratio of the pipe network transmission and distribution system and the module power consumption and heat transfer ratio of each transmission and distribution module are calculated.

[0071] In implementation, the balancing and scheduling component receives the water supply heat value and energy consumption information sent by each heat data collector and each energy consumption information collector in real time, and calculates the total power consumption to heat transmission ratio and the module power consumption to heat transmission ratio based on these collected data in real time or periodically.

[0072] Specifically, the power consumption to heat transfer ratio η can be calculated based on the following formula: η=D / Q Among them, D is the power consumption and Q is the calorific value.

[0073] In a specific example, when calculating the total power consumption to heat transfer ratio, the power consumption of all water pumps in the pipe network distribution system during the calculation period can be counted as the value of D, and the heat value collected by the heat data collector 210a corresponding to the heat source water supply pump can be used as the value of Q, and then based on the above formula, the total power consumption to heat transfer ratio η0 can be calculated.

[0074] When calculating the module power consumption and heat transfer ratio of the distribution module 141, the power consumption of each water pump in the distribution module 141 (such as the distribution water supply pump 1411 and the partition return water pump 1412b) during the calculation period can be counted as the value of D, and the heat value collected by the heat data collector 210b corresponding to the distribution water supply pump 1411 is used as the value of Q, and then based on the above formula, the module power consumption and heat transfer ratio η1 is calculated.

[0075] When calculating the module power consumption and heat transfer ratio of the distribution module 142, the power consumption of each water pump in the distribution module 142 (such as the distribution water supply pump 1421 and the two partition return water pumps 1422b) during the calculation period can be counted as the value of D, and the heat value collected by the heat data collector 210c corresponding to the distribution water supply pump 1421 is used as the value of Q, and then based on the above formula, the module power consumption and heat transfer ratio η2 is calculated.

[0076] The electricity consumption to heat transfer ratio is used to evaluate the transmission and distribution energy efficiency level. The smaller the electricity consumption to heat transfer ratio, the higher the transmission and distribution energy efficiency level.

[0077] S402, comparing the power consumption and heat transfer ratio of each module with the total power consumption and heat transfer ratio to determine whether there is a situation where the power consumption and heat transfer ratio of the distribution module is greater than the total power consumption and heat transfer ratio.

[0078] In implementation, since the heat source needs to transport heat to the entire pipeline distribution system and maintain the heating of each distribution module and other system equipment such as the heat source distribution return pipe, generally speaking, the power consumption to heat ratio of each distribution module should be less than the total power consumption to heat ratio. Therefore, by comparing the power consumption to heat ratio of each module with the total power consumption to heat ratio, if there is a situation where the power consumption to heat ratio of a module should be greater than the total power consumption to heat ratio, it means that the energy efficiency level of the corresponding distribution module is too low and needs to be balanced.

[0079] S403, when the module power consumption and heat transfer ratio is greater than the total power consumption and heat transfer ratio, determine the first target control parameter of the target partition return water regulator.

[0080] Among them, the target partition return water regulator is the partition return water regulator in each distribution module whose module power consumption and heat transfer ratio is greater than the total power consumption and heat transfer ratio.

[0081] In one implementation, the balancing scheduling component determines the first target control parameter according to the difference in the power consumption to heat transfer ratio between the two and a preset adjustment strategy.

[0082] In another implementation, see Figure 5 The method for the balance scheduling component to determine the first target control parameter specifically includes the following steps: S501, obtaining heat control parameters of heat zones.

[0083] During implementation, the management system can record and store the heat control parameters input by the user, and the balancing and regulating component accesses the storage space to obtain the heat control parameters corresponding to each heat partition in each transmission and distribution module.

[0084] S502: Evaluate heat demand of zoned users based on heat control parameters, and determine a first target control parameter based on the heat demand of the users.

[0085] The first target control parameter includes an updated value of the first temperature threshold or an updated value of the second temperature threshold.

[0086] In implementation, the heat control parameters corresponding to the heat zones in the current cycle can be counted to determine whether the heat demand of zone users is to increase the heating temperature or to reduce the heating temperature.

[0087] In one example, the temperature adjustment average value of all heat units in the partition in the current cycle can be calculated based on the heat control parameters, and then the user's heat demand can be determined based on the average value, wherein the temperature adjustment average value is calculated by determining the difference between the target temperature set by the user and the actual temperature based on each heat control parameter, and calculating the average of all the differences. It can be understood that before the average value is calculated, the heat control operating parameters can also be preprocessed to ensure the validity of the data, and the preprocessing includes but is not limited to data clarity, outlier removal, missing value completion, etc.

[0088] When the average value is positive, the heat demand is determined to increase the heating temperature, and when the average value is negative, the heat demand is determined to decrease the heating temperature.

[0089] When the heat demand is to increase the heating temperature, the average value may be determined as the updated value of the first temperature threshold; when the heat demand is to reduce the heating temperature, the average value may be determined as the updated value of the second temperature threshold. In implementation, the average value may be directly determined as the updated value.

[0090] It is understandable that when the absolute value of the updated value is greater than the absolute value of the difference between the first temperature threshold and the second temperature threshold, the corresponding temperature threshold needs to be adjusted synchronously to avoid control logic errors.

[0091] It is understandable that when there are multiple heat zones, the heat demands corresponding to different heat zones may be different. Therefore, the first target control parameters corresponding to the return water regulators of each zone are also different.

[0092] S404, sending the first target control parameter to the target partition return water regulator.

[0093] Among them, the target distribution and water supply regulator is the distribution and water supply regulator corresponding to the distribution module whose module power consumption and heat transfer ratio is greater than the total power consumption and heat transfer ratio.

[0094] After receiving the first target control parameter, the target partition return water regulator will update the local first temperature threshold and the second temperature threshold based on the first target control parameter, and regulate and control the partition return water pump based on the updated thresholds.

[0095] Please refer to Figure 6 The method for the partition return water regulator to adjust the partition return water pump in real time based on the first temperature threshold and the second temperature threshold specifically includes the following steps: S601, obtaining in real time the secondary water supply temperature and secondary return water temperature of the heat zone where the zone return water pump is located, and calculating the average temperature.

[0096] In implementation, the average temperature can be obtained by calculating the average of the secondary water supply temperature and the secondary return water temperature.

[0097] S602, respectively determining the magnitude relationship between the average temperature and the first temperature threshold and the second temperature threshold.

[0098] The first temperature threshold is smaller than the second temperature threshold.

[0099] When the average temperature is less than the first temperature threshold, execute step S603; when the average temperature is greater than the second temperature threshold, execute step S604; when the average temperature is greater than or equal to the first temperature threshold and less than or equal to the second temperature threshold, no processing is performed.

[0100] S603, flow acceleration is achieved by adjusting the zone return water pump.

[0101] S604, by adjusting the zone return pump to achieve flow rate reduction.

[0102] During implementation, the zone return water regulator can adjust the zone return water pump according to the flow control target, and monitor the relationship between the average temperature and the first temperature threshold and the second temperature threshold in real time. When the average temperature is greater than or equal to the first temperature threshold and less than or equal to the second temperature threshold, the adjustment of the zone return water pump is stopped.

[0103] When the zone return water regulator adjusts the zone return water pump, the distribution water supply regulator can synchronously adjust the distribution water supply pump, so that the distribution water supply pump can follow the zone return water pump to adjust the flow in the same direction.

[0104] In one example, when the zone return water regulator controls the zone return water pump, it can send a synchronous adjustment instruction to the transmission and distribution water supply regulator to trigger the transmission and distribution water supply regulator to obtain the change of water supply flow through the heat data collector 210 corresponding to the transmission and distribution water supply pump when receiving the synchronous adjustment instruction, and adjust the transmission and distribution water supply pump in the same direction according to the change of water supply flow to assist in achieving stable operation in the heat-using zone and balance the pressure on both sides. Among them, the same-direction adjustment method includes adjusting the transmission and distribution water supply pump to increase the water supply flow synchronously when the water supply flow is monitored to increase; when the water supply flow is monitored to decrease, the transmission and distribution water supply pump is adjusted to reduce the water supply flow synchronously.

[0105] Based on this, when the distribution and supply regulating pump receives the synchronous adjustment instruction, it controls the distribution and supply pump to stabilize the flow in the distribution module, adjust the flow under the same working conditions, and adjust in the same direction as the zone return pump. In this way, the zone return pump plays an active adjustment role to follow the temperature changes of the secondary supply and return water to meet the user's heating needs. The distribution and supply pump plays a stabilizing operation role, assisting in reducing the design margin and meeting the adjustment threshold under different load conditions. In this way, the wide adjustment problem of a single water pump can be reduced.

[0106] Based on the above method, the zone return water regulator can automatically adjust the zone return water pump according to the secondary water supply temperature and secondary return water temperature of the heat-using zone, so that the secondary water supply temperature can meet the actual needs of users and make adaptive adjustments as the user's needs change, thereby avoiding the situation where users frequently adjust the heat control parameters due to unreasonable heating, thereby improving user satisfaction; at the same time, when the flow of the zone return water pump is adjusted, a synchronous adjustment instruction is sent to the distribution water supply regulator of the distribution module, so that the distribution water supply regulator can make the same direction adjustment according to the real-time flow changes in the distribution module. On the one hand, it can make the flow in the module quickly return to stability, thereby reducing the impact on other heat-using zones, and on the other hand, it can expand the adjustment range through the linkage of dual pumps.

[0107] Furthermore, the energy efficiency level of each transmission and distribution module of the system is monitored in real time through the balancing and control component, and the transmission and distribution modules that need to be adjusted for heating are located according to the relationship between the power consumption and heat transmission ratio of each transmission and distribution module and the system, and then the control parameters of the corresponding zone return water regulator are updated, thereby realizing the automatic optimization of the control parameters of the return water regulators in each zone in the system. In this way, it can not only automatically adapt to the dynamic changes in user heat demand and improve user heat satisfaction, but also continuously and dynamically and flexibly evaluate the energy efficiency of each transmission and distribution module. Compared with the evaluation method based on fixed indicators, it has better adaptability and avoids the problem of insufficient development of system regulation capabilities due to unreasonable evaluation indicators.

[0108] In the embodiments of the present application, energy-saving excavation of the pump operation can also be achieved based on the water supply regulator.

[0109] Specifically, the distribution and water supply regulator obtains the flow data of the heat data collector in real time to obtain the outlet flow of the distribution and water supply pump. When the flow is detected to be stable and lasts for a preset time, the distribution and water supply pump is controlled to gradually adjust the frequency downward with the target unit amplitude until the change of the outlet flow data exceeds the target change range, and then the downward adjustment is stopped. Among them, the preset time, target unit and target change range are sent to each distribution and water supply regulator by the balance control component in the form of the second target control parameter. The method of judging whether the outlet flow is stable includes that the change frequency of the flow is lower than the preset change frequency.

[0110] During implementation, the balancing and control component can first set a unified initial value for each transmission and distribution water supply regulator, including the initial preset duration, the initial target unit and the initial target change range, and during the operation of the system, continuously collect the number of downward frequency adjustments of each transmission and distribution water supply regulator, as well as the changes in the user heat control parameters of the application heat partition after each downward adjustment, so as to dynamically adjust the target unit and target change range of each transmission and distribution water supply regulator, set personalized target units and target change ranges for each transmission and distribution water supply regulator, and realize differentiated operation energy-saving capability mining according to the actual conditions of different transmission and distribution modules.

[0111] In one example, the initial preset duration is 30 minutes, the target unit is 0.5 Hz, and the target variation range is ±3%.

[0112] In an embodiment of the present application, the heat source water supply regulator can determine the target flow rate according to the pressure difference between the inlet and outlet of the heat source water supply pump, and adjust the heat source water supply pump based on the target flow rate to control the heat source water supply flow rate to meet the target flow rate requirement.

[0113] Specifically, the heat source water supply regulator can obtain the pressure difference ΔP on both sides of the heat source water supply pump in real time based on the first pressure difference acquisition unit, and calculate the target flow rate G based on the following formula: ΔP=SG² Among them, S is the pipeline resistance coefficient of the pipeline distribution system, which is a constant obtained by numerical measurement and calculation during the trial operation of the pipeline distribution system.

[0114] At the same time, the current flow rate is determined according to the calorimeter corresponding to the heat source water supply pump, and the flow rate of the heat source water supply pump is adjusted according to the target flow rate and the current flow rate, so that the flow rate measured by the calorimeter meets the target flow rate requirements, that is, the same as the target flow rate, or the difference does not exceed the preset error range. Ensure the normal operation of the heat source.

[0115] In an embodiment of the present application, the heat source return water regulator can control the heat source return water pump according to the pressure difference on both sides of the heat source return water pump to avoid insufficient or excessive power of the heat source return water pump.

[0116] Specifically, the heat source return water regulator can obtain the pressure difference on both sides of the heat source return water pump through the second pressure difference acquisition unit, and when the pressure difference exceeds the second preset balance range, adjust the heat source return water pump to make the pressure difference return to the second preset balance range. This can avoid the problem of insufficient power of the heat source return water pump, resulting in the inability to discharge the return water of each distribution module in time, thereby generating additional system pressure on other water pumps of the distribution module and increasing system energy consumption. At the same time, it can avoid the problem of increasing the internal pressure of the heat source due to excessive power of the heat source return water pump, causing excessive loss of the heat source, and causing other regulators to perform unnecessary control and adjustment operations on the water pump, thereby increasing system energy consumption.

[0117] In addition, in order to maintain the stable pressure inside the heat source, the heat source return water regulator can also adjust the heat source return water pump according to the pressure changes at the heat source outlet, so that the pressure at the heat source outlet returns to stability, thereby ensuring that the heat source maintains its own safety during the external adjustment process.

[0118] Specifically, the heat source return water regulator obtains the inlet pressure data of the heat source water supply pump in real time through the first pressure difference acquisition unit as the pressure data of the heat source outlet, monitors the change of the pressure data, and controls the heat source return water pump when abnormal changes in the pressure data are detected to return the pressure data to normal. Among them, the heat source return water regulator can determine whether the heat source outlet pressure is within the target pressure range according to the target pressure range issued by the balance adjustment group. If it is not within the target pressure range, it is determined that the pressure data change is abnormal. Otherwise, the pressure data change is normal.

[0119] In the implementation of the present application, the distribution water supply regulator monitors the inlet and outlet pressure difference of the distribution module in real time through the third pressure difference acquisition unit to determine whether the module pressure difference is abnormal, that is, whether it exceeds the third preset balance range; each partition return water regulator monitors the inlet and outlet pressure difference of the partition in real time through the fourth pressure difference acquisition unit to determine whether the partition pressure difference is abnormal, that is, whether it exceeds the fourth preset balance range. Among them, the second preset balance range, the third preset balance range and the fourth preset balance range are set by the balance control component according to the actual situation of the system.

[0120] When the zone return water regulator determines that the zone inlet and outlet pressure difference is abnormal, it immediately adjusts the zone return water pump to restore the pressure difference to the fourth preset balance range, and sends a synchronous control instruction to the distribution water supply regulator.

[0121] When the distribution water supply regulator detects an abnormal pressure difference, it first enters the adjustment waiting mode to receive the synchronous control instructions sent by the return water regulators of each partition during the waiting period, and enters the synchronous adjustment mode according to any synchronous control instructions received during the waiting period to perform synchronous adjustment. The method of synchronous adjustment is the same as described above and will not be repeated here.

[0122] If no synchronous control instruction is received during the waiting period, or if the inlet and outlet pressure difference of the distribution module is still abnormal after the synchronous adjustment is completed, a module abnormality notification is sent to the balance control component. After receiving the module abnormality notification, the balance control component sends an early warning message through the management system, and sends adjustment instructions to the partition return water regulator in the distribution module in turn according to the adjustment strategy, so as to trigger the partition return water regulator to adjust the partition return water pump based on the target adjustment unit, so as to restore the pressure difference stability of the distribution module as soon as possible. Among them, the target adjustment unit can be the minimum flow adjustment unit.

[0123] Specifically, the balance control component can determine the pressure difference adjustment amplitude of each partition according to the heat demand corresponding to each heat partition in the abnormal transmission and distribution module, and determine the sending time of each adjustment instruction based on the pressure difference adjustment amplitude of each partition to generate an adjustment strategy, wherein the greater the heat demand, the greater the pressure difference adjustment amplitude, the earlier the sending time, and the sending time interval between two adjacent adjustment instructions is determined based on the difference between the pressure difference adjustment amplitudes of the two. In one example, the total adjustment amplitude is first determined based on the direct difference between the module pressure difference and the third preset range, and the ratio of each heat demand to the total heat demand is calculated respectively, and then the pressure difference adjustment amplitude is obtained by calculating the product of each ratio and the total adjustment amplitude. It can be understood that when there are negative numbers in each heat demand, each heat demand needs to be processed first so that the processed values ​​are all positive numbers and the size relationship remains unchanged.

[0124] After receiving the adjustment instruction, each zone return water regulator immediately adjusts the flow of the zone return water pump based on the target adjustment unit.

[0125] During the zoning adjustment process, the distribution water supply regulator can obtain flow changes based on the flow meter and make synchronous adjustments to achieve linkage. At the same time, it continuously monitors the module pressure difference. When the module pressure difference returns to normal, it sends a normal pressure difference notification to the balancing scheduling component to avoid excessive adjustment.

[0126] After receiving the normal pressure difference notification, the balancing and scheduling component stops sending adjustment instructions. If the balancing and scheduling component has not received the normal pressure difference notification after completing one round of adjustment instructions, it will send a new round of adjustment instructions according to the adjustment strategy to trigger the return water regulators of each partition to adjust the flow again based on the target adjustment unit until the normal pressure difference notification is received or the adjustment time exceeds the limit time.

[0127] Based on this, the balancing control component sends adjustment instructions to the partition return water regulator based on the adjustment strategy, and when the distribution and supply water regulator determines that the module pressure difference is stable, it can directly stop sending the adjustment instructions to complete the pressure difference adjustment. On the one hand, it can avoid excessive interference with the flow of the partition, resulting in the destruction of the balance of partition operation. On the other hand, during the adjustment process, it can use the linkage of the distribution and supply water pumps to achieve rapid and stable flow regulation.

[0128] In one example, the balancing and control component can calculate the heat control parameters of the users corresponding to each heat usage zone in the current cycle to obtain the heat demand, and determine the pressure difference adjustment amplitude of each zone according to the size of the heat demand, wherein the pressure difference adjustment amplitude allocated to the adjustment zone with the smallest heat demand is the smallest.

[0129] In one example, heat zones with heat demand greater than zero can be selected to participate in pressure difference regulation, and regulation strategies are generated only for the heat zones participating in the regulation. In this way, adverse effects on the normal heating regulation state of the heat zones can be avoided as much as possible, thereby generating additional energy consumption. At the same time, accelerated regulation of the zones participating in the regulation can be promoted to restore the pressure difference to stability as soon as possible while meeting the user's heating needs.

[0130] It is understandable that if the number of heat zones with heat demand greater than zero does not meet the quantity requirement, heat zones with larger heat demand can be selected to participate in the pressure difference regulation until the number meets the requirement.

[0131] For example, the temperature adjustment value for each adjustment can be calculated based on the difference between the target temperature and the current temperature in the heat control parameter, and the temperature adjustment values ​​in the current cycle are accumulated to obtain the total adjustment value, and the total adjustment value is converted into the heat demand according to the adjustment direction of the pressure difference. Among them, if the adjustment direction of the pressure difference is to increase the outlet pressure, it indicates that the flow rate needs to be increased by controlling the partition return pump. At this time, the total adjustment value is directly determined as the heat demand; if the adjustment direction of the pressure difference is to reduce the outlet pressure, it indicates that the flow rate needs to be reduced by controlling the partition return pump, and the opposite of the total adjustment value is taken as the heat demand. In one example, when the number meets the preset requirements, the heat partition with a heat demand greater than zero can be selected as the heat partition participating in the adjustment.

[0132] In the implementation of the present application, in order to maintain the stable operation of the distribution module, the distribution water supply regulator can also monitor the pressure value at the inlet of the distribution module in real time based on the third pressure difference acquisition unit, and control the distribution water supply pump according to the pressure value to avoid cavitation caused by excessive pressure at the inlet of the distribution module, so as to ensure the safe and stable operation of the system equipment.

[0133] Based on the management system and pipeline distribution system provided in the embodiments of the present application, each heat zone is independently controlled to meet different heat demands, and the synchronous adjustment of the zone return pump and the distribution water supply pump helps to quickly balance the heat zone and respond to changes in user heat demand in a timely manner.

[0134] Through the balanced scheduling components, refined control of each transmission and distribution module is achieved. Through the linkage of multi-stage pumps, excessive modulation of a single water pump can be avoided, thereby reducing the installed configuration of water pumps at each stage, achieving the purpose of reducing the total power load of the system, and helping to save energy and reduce carbon emissions while achieving improved transmission and distribution energy efficiency.
