Description

Technical Field

[0001] This application relates to the technical field of intelligent heating, and more specifically, to a method, device, equipment and readable storage medium for operating and regulating a heat exchange unit. Background Art

[0002] Currently, building energy consumption is mainly for heating and cooling. And heating is commonly realized by using a heat exchange unit. A heat exchange unit is a complete set of heat exchange equipment that is organically combined and can perform heat exchange between steam and water, or between water and water.

[0003] Currently, the regulation modes of the heating system include an hourly regulation mode and a time-sharing regulation mode based on manual experience. Among them, the hourly regulation mode specifically refers to predicting the heat quantity per hour, and then regulating according to the predicted heat quantity per hour. This regulation mode is too frequently operated, which is likely to cause oscillations in the heating system. In addition, due to the delay and thermal inertia between the primary network side and the secondary network side, and the inability to batch collect the room temperature data at the user end, etc., it is difficult to implement the hourly regulation mode. The time-sharing regulation mode based on manual experience will be affected by factors such as the subjective experience of each regulator, resulting in greater differences in regulation.

[0049] The core of the present application is to provide an operation regulation method, device, equipment and readable storage medium for a heat exchange unit, which is used to perform more reasonable operation regulation on the heat exchange unit.

[0050] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0051] See Figure 1 , which shows a flow chart of an operation regulation method for a heat exchange unit provided by an embodiment of the present application. The operation regulation method for a heat exchange unit provided by an embodiment of the present application may include:

[0052] S11: Obtain the historical regulation data of the heat exchange unit, divide the heating season into multiple regulation periods according to the historical regulation data, and divide each single day in each regulation period into multiple regulation time periods.

[0053] In this application, first, the historical regulation data of the heat exchange unit can be obtained from the platform corresponding to the heating system that stores the historical data of the heat exchange unit. Here, the historical regulation data specifically can be the regulation data of the heat exchange unit during the heating season last year or in the heating seasons of previous years. And the historical regulation data includes but is not limited to the number of regulation times per day, the regulation time per day, and the heat value supplied by the heat exchange unit per day (i.e., the heat supply value) during the heating season. And in this application, specifically, the regulation data of the manual operation and regulation of the heat exchange unit based on experience within the historical time can be obtained. Of course, the historical regulation data of the heat exchange unit can also be obtained after the heat exchange unit is operated and regulated according to the technical solution provided in this application, so as to continuously improve the operation and regulation method of the heat exchange unit. For example, assume that the heat exchange unit was operated and regulated according to the operation and regulation method of the heat exchange unit provided in this application during the heating season last year. Then in this year, the historical regulation data of the heat exchange unit last year can be obtained to continuously improve the operation and regulation method of the heat exchange unit, etc., so as to facilitate improving the rationality and reliability of the operation and regulation of the heat exchange unit.

[0054] After obtaining the historical regulation data, the historical regulation data can be analyzed and processed, and the heating season can be divided into multiple regulation periods according to the historical regulation data. Moreover, when analyzing and processing the historical regulation data, not only can the heating season be divided into multiple regulation periods according to the historical regulation data, but at the same time, the division rule of the single-day regulation time period in each regulation period can be determined (for example, the single-day regulation is 2 - 5 times), and accordingly, the single day in each regulation period can be divided into multiple regulation time periods. That is, according to the historical regulation data, the heating season can be divided into multiple regulation periods and the single day in each regulation period can be divided into multiple regulation time periods simultaneously. It should be noted that within the same regulation period, the number of regulation times and the division of the regulation time period for each day are the same.

[0055] S12: Obtain the historical operation data of the heat exchange unit, and determine the heat distribution ratio of each regulation time period of a single day in each regulation period according to the historical operation data.

[0056] In this application, when obtaining the historical regulation data of the heat exchange unit (simultaneously or before or after), the historical operation data of the heat exchange unit can also be obtained. Here, the historical operation data of the heat exchange unit specifically can include data such as the secondary network supply water temperature, the secondary network return water temperature, the secondary network supply and return water temperature difference, and the secondary network side flow rate.

[0057]

[0058] ​Through steps S11 and S12, the division of the regulation period, the division of the single-day regulation time periods in the regulation period, and the determination of the heat distribution ratio for each single-day regulation time period in each regulation period can be achieved based on the historical data of the heat exchange unit, so that subsequent operation regulation of the heat exchange unit can be carried out based on the determined information, making the operation regulation of the heat exchange unit more in line with the actual requirements and achieving more reasonable operation regulation of the heat exchange unit.

[0059] S13: Determine the target regulation period to which the day to be regulated belongs, divide the regulation time periods for the day to be regulated, and determine the heat distribution ratio for each regulation time period of the day to be regulated.

[0060] Based on steps S11 and S12, when it is necessary to perform operation regulation on the heat exchange unit on the day to be regulated, the target regulation period to which the day to be regulated belongs can be determined according to the regulation periods divided in step S11 and the day to be regulated, that is, to determine which regulation period in the division in step S11 the day to be regulated is located in. Among them, the day to be regulated is in the heating season and is a future day. For example, if the current day has not entered this year's heating season, the day to be regulated can be any day in this year's heating season after the current day, or if the current day is in this year's heating season, the day to be regulated can be any day after the current day and within this year's heating season.

[0061] After determining the target regulation period to which the day to be regulated belongs, the single day in each regulation period can be divided into multiple regulation time periods according to step S11, that is, according to the division of the single-day regulation time periods in each regulation period in step S11, the regulation time periods for the day to be regulated are divided. Specifically, the day to be regulated is divided into the same regulation time periods as those into which the single day in the target regulation period to which it belongs is divided. And, according to the heat distribution ratio for each single-day regulation time period determined in step S12, the heat distribution ratio for each regulation time period of the day to be regulated can be determined. Specifically, the heat distribution ratio for each regulation time period of the day to be regulated is the same as the heat distribution ratio for each single-day regulation time period in the target regulation period to which it belongs.

[0062] S14: Calculate the heat prediction value for the day to be regulated, determine the heat prediction value for each regulation time period of the day to be regulated according to the heat prediction value and the heat distribution ratio for each regulation time period of the day to be regulated, and perform operation regulation on the heat exchange unit on the day to be regulated according to the regulation time period division of the day to be regulated and the heat prediction value for each regulation time period.

[0063] After determining the aforementioned days to be regulated, the heat prediction algorithm model and heat prediction influence parameters (the heat prediction influence parameters mentioned here are the input parameters of the heat load prediction algorithm model) can be used to calculate the heat prediction value of the heat exchange unit on the day to be regulated. Among them, the output result of the heat load prediction algorithm model mentioned here can be the instantaneous heat value on the primary network side or the secondary network side. Specifically, the instantaneous heat, the difference between the accumulated heat of two adjacent hours, or the heat load calculation formula can be selected to obtain the heat value, etc. Among them, in the aforementioned calculation formula, Q is the heat load, G is the flow rate on the primary network side or the secondary network side of the heat exchange unit, c is the specific heat capacity of water, and t g is the supply water temperature, and t h is the return water temperature. It should be noted that the aforementioned heat load prediction algorithm model can be an existing algorithm model or a newly built algorithm model for heat prediction. Among them, when using an existing algorithm model, the algorithm model used in the existing hourly operation regulation can be used to predict the heat of each hour on the day to be regulated. Then, the heat prediction values of each hour on the day to be regulated can be added up to obtain the heat prediction value of the day to be regulated.

[0064] After calculating the heat prediction value of the day to be regulated, the heat prediction value of each regulation period on the day to be regulated can be calculated based on the calculated heat prediction value of the day to be regulated and the heat distribution ratio of each regulation period obtained in step S13. Then, the operation of the heat exchange unit on the day to be regulated can be controlled according to the division of the regulation periods on the day to be regulated and the heat prediction values of each regulation period on the day to be regulated. That is, it can be determined when the operation state of the heat exchange unit changes and how long the changed operation state should be maintained according to the division of the regulation periods on the day to be regulated, and the specific operation state of the heat exchange unit in each regulation period can be determined according to the heat prediction values of each regulation period on the day to be regulated. Then, the operation of the heat exchange unit on the day to be regulated can be controlled based on this information. Among them, after obtaining the heat prediction values of each regulation period on the day to be regulated, the heat prediction value of each hour in each regulation period on the day to be regulated can be obtained by averaging according to the heat prediction value of each regulation period on the day to be regulated, so that the heat prediction value of each hour can be obtained when controlling the operation of the heat exchange unit on the day to be regulated and the operation can be controlled. Among them, in this case, the operation state of the heat exchange unit does not change every hour within the same regulation period, so that the heat value of each hour within the same regulation period can be the same as the corresponding heat prediction value of each hour.

[0065] Through the above method, it is possible to automatically determine the regulation time periods into which the heat exchange unit is divided on the day to be regulated and the heat distribution ratio of each regulation time period based on the historical data of the heat exchange unit, calculate the heat prediction values for each regulation time period on the day to be regulated, and achieve the operation regulation of the heat exchange unit according to the division of the regulation time periods on the day to be regulated and the heat prediction values of each regulation time period, rather than regulating the operation of the heat exchange unit in the way of predicting hour by hour and regulating hour by hour, and also no longer regulating the operation of the heat exchange unit according to manual experience. Compared with the hour-by-hour operation regulation, the operation regulation method provided by the present application can reduce the frequency of operation regulation, thereby reducing the oscillation of the heating system during the regulation process; compared with regulating the operation according to manual experience, the operation regulation method provided by the present application is no longer affected by human factors. Through the operation regulation method provided by the present application, the operation regulation of the heat exchange unit can be more in line with the actual situation, and the operation regulation of the heat exchange unit can be made more reasonable, realizing the digitization and intelligence of the operation regulation of the heat exchange unit.

[0066] According to the above technical solution disclosed in the present application, the heating season is divided into multiple regulation cycles based on the historical data of the heat exchange unit, each single day in each regulation cycle is divided into multiple regulation time periods, and the heat distribution ratio of each regulation time period in a single day in each regulation cycle is determined. Then, the target regulation cycle to which the day to be regulated belongs is determined, the day to be regulated is divided into regulation time periods according to the division of the regulation time periods in a single day in the target cycle, and the heat distribution ratio of each regulation time period on the day to be regulated is determined according to the heat distribution ratio of each regulation time period in a single day in the target cycle. After that, the heat prediction values for each regulation time period on the day to be regulated are determined according to the heat distribution ratio of each regulation time period on the day to be regulated and the calculated heat prediction value of the day to be regulated. Subsequently, the operation of the heat exchange unit on the day to be regulated is regulated according to the division of the regulation time periods on the day to be regulated and the heat prediction values of each regulation time period, that is, the division of the regulation time periods and the determination of the heat prediction values corresponding to each regulation time period are carried out according to the historical data of the heat exchange unit, and the operation of the heat exchange unit is regulated accordingly, so as to realize more reasonable operation regulation of the heat exchange unit, reduce the frequency of operation regulation of the heat exchange unit, thereby reducing the oscillation of the heating system during the regulation process, and making the operation regulation of the heat exchange unit meet the actual requirements.

[0067] See Figure 2 , which shows a flowchart of another method for regulating the operation of a heat exchange unit provided by an embodiment of the present application. A method for regulating the operation of a heat exchange unit provided by an embodiment of the present application, which divides the heating season into multiple regulation cycles according to historical regulation data and divides each single day in each regulation cycle into multiple regulation time periods, may include:

[0068] Dividing the heating season into multiple regulation cycles according to the outdoor temperature and heat value of each day in the heating season within the historical time;

[0069] Divide the single days in each regulation period into multiple regulation time periods according to the number of regulations per day and the regulation time corresponding to each regulation in each regulation period.

[0070] In this application, when dividing the heating season into multiple regulation periods according to historical regulation data and dividing the single days in each regulation period into multiple regulation time periods, specifically, the heating season can be divided into multiple regulation periods according to the outdoor temperature and the heat value per day in the heating season within the historical time (both of these two parameters are obtained from the historical regulation data). At this time, the historical regulation data also includes the data of the outdoor temperature per day. For example, the outdoor temperature and the corresponding heat value can be classified into one category, and the heating season can be divided into multiple regulation periods based on the classified categories. Specifically, according to the fluctuation of the heat historical data (which is related to the outdoor temperature), a heating season can be divided into several regulation periods based on similar regulation amplitudes and waveforms. And, according to the number of regulations each time and the regulation time corresponding to each regulation per day in each divided regulation period (both of these two parameters are also obtained from the historical regulation data), the single days in the corresponding regulation period can be divided into multiple regulation time periods by using the highest frequency or average value, etc.

[0071] Through the above method, the division of the regulation period is realized according to the outdoor temperature and the heat value, and the division of the single-day regulation time period is carried out according to the number of regulations per day and the regulation time corresponding to each regulation in the regulation period, so as to improve the reliability and accuracy of the division of the regulation period and the single-day regulation time period.

[0072] A method for regulating the operation of a heat exchange unit provided by an embodiment of this application, which divides the heating season into multiple regulation periods according to historical regulation data and divides the single days in each regulation period into multiple regulation time periods, may include:

[0073] Divide the heating season into multiple regulation periods according to a preset time span, and divide the single days in each regulation period into multiple regulation time periods according to the number of regulations per day and the regulation time corresponding to each regulation in each regulation period.

[0074] In this application, when dividing the heating season into multiple regulation periods according to historical regulation data and dividing the single days in each regulation period into multiple regulation time periods, first, the heating season can be divided into multiple regulation periods according to a preset time span (for example: the initial stage of heating, the severe cold period, the end stage, or in the ways of month, ten-day period, week, day, public holiday, etc.). After that, according to the number of regulations each time and the regulation time corresponding to each regulation per day in each divided regulation period (both of these two parameters are obtained from the historical regulation data), the single days in the corresponding regulation period can be divided into multiple regulation time periods by using the highest frequency or average value, etc.

[0075] By the above method, the regulation cycle is divided according to the set preset time span, and on this basis, the single-day regulation time periods in the corresponding regulation cycles are divided according to the daily regulation times and the time of each regulation, so that the division of the regulation cycle can be carried out according to actual requirements, and the accuracy and reliability of the division of the single-day regulation time periods in the regulation cycle are improved.

[0076] A heat exchange unit operation regulation method provided by an embodiment of the present application, which determines the heat distribution ratio of each single-day regulation time period in each regulation cycle according to historical operation data, may include:

[0077] Obtain the relationship between the secondary network supply water temperature per hour among the single-day regulation time periods in the regulation cycle when the secondary network side flow rate remains unchanged, and obtain the maximum secondary network supply water temperature per hour and the minimum secondary network supply water temperature per hour from the historical operation data;

[0078] According to the relationship between the secondary network supply water temperature per hour among the single-day regulation time periods in the regulation cycle, the maximum secondary network supply water temperature per hour and the minimum secondary network supply water temperature per hour, determine multiple first data groups corresponding to the single day in the regulation cycle; each first data group may include the secondary network supply water temperature per hour corresponding to each single-day regulation time period;

[0079] Obtain the secondary network supply and return water temperature difference per hour corresponding to each secondary network supply water temperature per hour in each first data group when the secondary network side flow rate remains unchanged, and use the secondary network supply and return water temperature difference per hour corresponding to each secondary network supply water temperature per hour in each first data group to calculate the second data group corresponding to each first data group; each second data group may include the heat ratio per hour corresponding to each single-day regulation time period;

[0080] Use each second data group to calculate the average heat ratio per hour corresponding to each single-day regulation time period;

[0081] According to the average heat ratio per hour corresponding to each single-day regulation time period and the duration of each single-day regulation time period, calculate the heat distribution ratio of each single-day regulation time period.

[0082] In the present application, the specific process of determining the heat distribution ratio of each single-day regulation time period in each regulation cycle according to historical operation data is as follows:

[0083] 1) Clean abnormal data by methods such as box plots or using the internal relationships of historical operation data. Using the cleaned data, sort out the data of the secondary network supply water temperature, secondary network return water temperature, secondary network supply and return water temperature difference, and secondary network side flow rate of the heat exchange unit (these data all refer to the data per hour). Analyze and extract the variation law of the secondary network supply water temperature during each regulation period of a single day (specifically referring to the variation law of the secondary network supply water temperature per hour during each regulation period of a single day) under the condition that the secondary network side flow rate (i.e., the frequency of the secondary network side circulating water pump) remains unchanged, and establish a data expression. The following is an example: Assume that according to statistics and analysis, the single-day regulation in a certain regulation cycle is divided into four regulation periods, then the data expression is as follows:

[0084] The secondary network supply water temperature during the T1 - T2 period: X + a;

[0085] The secondary network supply water temperature during the T2 - T3 period: X + b;

[0086] The secondary network supply water temperature during the T3 - T4 period: X + c;

[0087] The secondary network supply water temperature during the T4 - T1 period: X;

[0088] The total duration from T1 to T4 is 24 hours of a single day.

[0089] Among them, T1, T2, T3, and T4 are respectively a certain moment point of a single day, X is the lowest secondary network supply water temperature of a single day, and a, b, and c are respectively the increased values relative to the lowest secondary network supply water temperature of a single day.

[0090] That is to say, after cleaning, sorting out, and analyzing the historical operation data of the heat exchange unit, the relationship of the secondary network supply water temperature per hour between each regulation period of a single day in each regulation cycle when the secondary network side flow rate remains unchanged is obtained.

[0091] 2) Obtain the maximum secondary network supply water temperature per hour and the minimum secondary network supply water temperature per hour from the historical operation data of the heat exchange unit.

[0092] 3) Clean the abnormal data by methods such as box plots or using the internal relationships of historical operation data. Using the cleaned data, sort out the data of the secondary network supply water temperature, secondary network return water temperature, secondary network side supply and return water temperature difference, secondary network side flow rate, etc. of the heat exchange unit (all these data refer to the data per hour). Analyze and extract the variation law of the secondary network side supply and return water temperature difference under the condition that the secondary network supply water temperature differs by a preset temperature step (specifically, it can be 1°C) per hour. Specifically, for each regulation period, the highest and lowest hourly secondary network supply water temperatures of each regulation time period on a single day can be determined according to the relationship between the hourly secondary network supply water temperatures among different regulation time periods on a single day in the regulation period. And the regulation time period with the highest hourly secondary network supply water temperature on a single day can be used as the first reference regulation time period on a single day, and the regulation time period with the lowest hourly secondary network supply water temperature on a single day can be used as the second reference regulation time period on a single day. Then, according to the obtained maximum hourly secondary network supply water temperature and the first reference regulation time period on a single day, minimum hourly secondary network supply water temperature and the second reference regulation time period on a single day, taking the maximum hourly secondary network supply water temperature as the first hourly secondary network supply water temperature of the first reference regulation time period on a single day (that is, as the hourly secondary network supply water temperature corresponding to the first reference regulation time period in the first data group), the hourly secondary network supply water temperatures corresponding to the first reference regulation time period in adjacent two first data groups differ by a preset temperature step, and the minimum hourly secondary network supply water temperature as the last hourly secondary network supply water temperature of the second reference regulation time period on a single day (that is, as the hourly secondary network supply water temperature corresponding to the second reference regulation time period in the last data group), in this way, multiple first data groups are determined according to the relationship between the hourly secondary network supply water temperatures among different regulation time periods on a single day in the regulation period. Among them, each first data group contains the hourly secondary network supply water temperatures corresponding to different regulation time periods on a single day. That is, in the first first data group, the hourly secondary network supply water temperature corresponding to the first reference regulation time period on a single day is the maximum hourly secondary network supply water temperature, in the last first data group, the hourly secondary network supply water temperature corresponding to the second reference regulation time period on a single day is the minimum hourly secondary network supply water temperature, and in adjacent two first data groups, the hourly secondary network supply water temperatures corresponding to the first reference regulation time period on a single day differ by a preset temperature step.It should be noted that when determining the secondary network supply water temperature per hour corresponding to the single-day first regulation period in each first data group according to the preset temperature step, if, when determining the secondary network supply water temperature per hour corresponding to the remaining regulation periods in the same first data group according to the relationship between the secondary network supply water temperatures per hour during each regulation period in the regulation cycle, there is no secondary network supply water temperature per hour in the historical operation data that is equal to the theoretical secondary network supply water temperature per hour corresponding to a certain regulation period calculated according to the aforementioned relationship, then a secondary network supply water temperature per hour that actually exists in the historical operation data and is close to the theoretical secondary network supply water temperature per hour corresponding to a certain regulation period calculated according to the aforementioned relationship can be obtained as the secondary network supply water temperature per hour corresponding to this regulation period. Through the above process, each single day in each regulation cycle corresponds to multiple first data groups.

[0093] 4) For each regulation cycle, obtain the secondary network supply-return water temperature difference per hour corresponding to each secondary network supply water temperature per hour in each first data group when the secondary network side flow rate remains unchanged from the historical operation data of the heat exchange unit. Since heat is proportional to the flow rate × secondary network supply-return water temperature difference, therefore, when the secondary network side flow rate remains unchanged, heat is proportional to the secondary network supply-return water temperature difference. After obtaining the secondary network supply-return water temperature difference per hour corresponding to each secondary network supply water temperature per hour in each first data group when the secondary network side flow rate remains unchanged from the historical operation data of the heat exchange unit, the second data group corresponding to each first data group can be calculated correspondingly by using the secondary network supply-return water temperature difference per hour corresponding to each secondary network supply water temperature per hour in each first data group. Among them, each second data group includes the heat proportion per hour corresponding to each regulation period on a single day. Specifically, for each first data group, the secondary network supply-return water temperature differences per hour corresponding to the secondary network supply water temperatures per hour corresponding to each regulation period on a single day can be added up to obtain the total secondary network supply-return water temperature difference per hour. After that, the ratio of the secondary network supply-return water temperature difference per hour corresponding to the secondary network supply water temperature per hour corresponding to each regulation period on a single day to the total secondary network supply-return water temperature difference per hour can be correspondingly used as the heat proportion per hour corresponding to each regulation period on a single day.

[0094] 5) For each regulation cycle, calculate the average heat proportion per hour corresponding to each regulation period on a single day in the regulation cycle by using each second data group. Specifically, the average operation is performed on the heat proportion per hour corresponding to each regulation period on a single day in all second data groups respectively to correspondingly obtain the average heat proportion per hour corresponding to each regulation period on a single day.

[0095] 6) For each regulation cycle, calculate the heat distribution ratio of each regulation period on a single day according to the average hourly heat ratio corresponding to each regulation period on a single day and the duration of each regulation period on a single day. Specifically, multiply the average hourly heat ratio corresponding to each regulation period on a single day by the number of continuous hours of the corresponding regulation period to obtain the heat ratio of each regulation period on a single day. Then, add up the heat ratios of each regulation period on a single day to obtain the total heat ratio on a single day. Finally, use the ratio of the heat ratio of each regulation period on a single day to the total heat ratio on a single day as the heat distribution ratio of each regulation period on a single day.

[0096] Through the above method, it is possible to calculate the heat distribution ratio of each regulation period in each regulation cycle according to the historical operation data of the heat exchange unit, improve the rationality and reliability of determining the heat distribution ratio of a single regulation period in the regulation cycle, and thus facilitate improving the rationality and reliability of the operation regulation of the heat exchange unit.

[0097] A heat exchange unit operation regulation method provided by an embodiment of the present application, when the flow rate on the secondary network side remains unchanged, obtains the hourly secondary network supply and return water temperature difference corresponding to each hourly secondary network supply water temperature in each first data group, and uses the hourly secondary network supply and return water temperature difference corresponding to each hourly secondary network supply water temperature in each first data group to calculate the corresponding second data group for each first data group, which may include:

[0098] Obtain the maximum hourly secondary network supply and return water temperature difference, the minimum hourly secondary network supply and return water temperature difference, and the random hourly secondary network supply and return water temperature difference corresponding to each hourly secondary network supply water temperature in each first data group;

[0099] According to the maximum hourly secondary network supply and return water temperature difference corresponding to each hourly secondary network supply water temperature in each first data group, calculate the first hourly heat ratio corresponding to each hourly secondary network supply water temperature in each first data group;

[0100] According to the minimum hourly secondary network supply and return water temperature difference corresponding to each hourly secondary network supply water temperature in each first data group, calculate the second hourly heat ratio corresponding to each hourly secondary network supply water temperature in each first data group;

[0101] According to the random hourly secondary network supply and return water temperature difference corresponding to each hourly secondary network supply water temperature in each first data group, calculate the third hourly heat ratio corresponding to each hourly secondary network supply water temperature in each first data group;

[0102] According to the first hourly heat proportion, the second hourly heat proportion, and the third hourly heat proportion corresponding to each hourly secondary network supply water temperature in each first data group, calculate the hourly average heat proportion corresponding to each hourly secondary network supply water temperature in each first data group, and use the hourly average heat proportion corresponding to each hourly secondary network supply water temperature as the hourly heat proportion corresponding to the corresponding regulation period on a single day.

[0103] In this application, when obtaining the hourly secondary network supply and return water temperature difference corresponding to each hourly secondary network supply water temperature in each first data group with the secondary network side flow unchanged, the specific implementation process of calculating the second data group corresponding to each first data group by using the hourly secondary network supply and return water temperature difference corresponding to each hourly secondary network supply water temperature in each first data group is as follows:

[0104] 41) Obtain the hourly maximum secondary network supply and return water temperature difference, the hourly minimum secondary network supply and return water temperature difference, and a random hourly secondary network supply and return water temperature difference corresponding to each hourly secondary network supply water temperature in each first data group from the historical operation data of the heat exchange unit; wherein, the random hourly secondary network supply and return water temperature difference is a random hourly secondary network supply and return water temperature difference other than the hourly maximum secondary network supply and return water temperature difference and the hourly minimum secondary network supply and return water temperature difference.

[0105] 42) For each first data group, add up the hourly maximum secondary network supply and return water temperature differences corresponding to each hourly secondary network supply water temperature to obtain the total hourly maximum secondary network supply and return water temperature difference, and then use the ratio of the hourly maximum secondary network supply and return water temperature difference corresponding to each hourly secondary network supply water temperature to the total hourly maximum secondary network supply and return water temperature difference as the first hourly heat proportion corresponding to each hourly secondary network supply water temperature. The first hourly heat proportion corresponding to each hourly secondary network supply water temperature in each first data group can be calculated in the aforementioned manner.

[0106] 43) For each first data group, add up the hourly minimum secondary network supply and return water temperature differences corresponding to each hourly secondary network supply water temperature to obtain the total hourly minimum secondary network supply and return water temperature difference, and then use the ratio of the hourly minimum secondary network supply and return water temperature difference corresponding to each hourly secondary network supply water temperature to the total hourly minimum secondary network supply and return water temperature difference as the second hourly heat proportion corresponding to each hourly secondary network supply water temperature. The second hourly heat proportion corresponding to each hourly secondary network supply water temperature in each first data group can be calculated in the aforementioned manner.

[0107] 44) For each first data group, the hourly random secondary network supply - return water temperature difference corresponding to each hourly secondary network supply water temperature can be added up to obtain the total hourly random secondary network supply - return water temperature difference. Then, the ratio of the hourly random secondary network supply - return water temperature difference corresponding to each hourly secondary network supply water temperature to the total hourly random secondary network supply - return water temperature difference is correspondingly used as the third hourly heat proportion corresponding to each hourly secondary network supply water temperature. The third hourly heat proportion corresponding to each hourly secondary network supply water temperature in each first data group can be calculated in the foregoing manner.

[0108] 45) For each first data group, the first hourly heat proportion, the second hourly heat proportion, and the third hourly heat proportion corresponding to each hourly secondary network supply water temperature are averaged to obtain the hourly average heat proportion corresponding to each hourly secondary network supply water temperature. And the hourly average heat proportion corresponding to each hourly secondary network supply water temperature can be used as the hourly heat proportion corresponding to the corresponding single - day regulation period (each hourly secondary network supply water temperature corresponds to a single - day regulation period), so as to obtain a second data group corresponding to each first data group.

[0109] By using the maximum secondary network supply - return water temperature difference, the minimum secondary network supply - return water temperature difference, and the random secondary network supply - return water temperature difference in the above - mentioned manner to calculate the hourly heat proportion corresponding to each regulation period of a single day, the reliability and rationality of the calculation can be improved. Of course, according to the actual situation, the hourly heat proportion corresponding to each regulation period of a single day can also be determined by using the hourly secondary network supply - return water temperature difference with the highest frequency or the hourly average secondary network supply - return water temperature difference corresponding to the hourly secondary network supply water temperature.

[0110] Before performing the operation regulation of the heat exchange unit on the to - be - regulated day according to the regulation period division of the to - be - regulated day and the heat prediction values of each regulation period, the method for operating and regulating a heat exchange unit provided by an embodiment of the present application may further include:

[0111] If the heat prediction influence parameter of the to - be - regulated day changes, then calculate the new heat prediction value of the to - be - regulated day according to the changed heat prediction influence parameter.

[0112] In the present application, before performing the operation regulation of the heat exchange unit on the to - be - regulated day according to the regulation period division of the to - be - regulated day and the heat prediction values of each regulation period, the heat prediction influence parameter of the to - be - regulated day (which may include weather data, etc., and is specifically determined according to the selected heat prediction algorithm) can be monitored in real - time or at regular intervals. If the heat prediction influence parameter of the to - be - regulated day changes, then the new heat prediction value of the to - be - regulated day can be calculated according to the changed heat prediction influence parameter, and the new heat prediction value is used to participate in the operation regulation of the heat exchange unit to improve the accuracy of the operation regulation of the heat exchange unit.

[0113] In addition, considering that the operation control strategy for a heating season is affected by various factors such as weather parameters, social factors, and the operation conditions of the heating system, it is necessary to make irregular adjustments. Specifically, the following dynamic adjustment strategy can be formulated: Use the historical heat data over a certain time span (such as months, dekads, weeks, 3 days, etc.) as the rolling data for this part of the algorithm model. If the single-day heat control period division and the heat distribution ratio for each control period change in a future time span (such as dekads, weeks, days, etc.), then the single-day control period division and the heat distribution ratio for each control period after this time span can be adjusted to the division and distribution method at this time span. That is, in this case, it can correspond to obtaining the historical control data of the heat exchange unit after performing operation control on the heat exchange unit according to the technical solution provided in this application, and using the historical control data of the heat exchange unit obtained in this case to divide the control period and the single-day control periods in the control period, etc., and the historical operation data corresponding to the heat exchange unit can be obtained to determine the heat distribution ratio for each single-day control period in the control period based on the historical operation data, so as to facilitate future operation control of the heat exchange unit based on this information.

[0114] A method for operating and controlling a heat exchange unit provided by an embodiment of this application may further include:

[0116] In this application, to ensure the safe and stable operation of the heating system and in coordination with the platform application interface, the operation functions such as adjusting the control period division for the entire heating season, the single-day control period division, and the determination of the heat distribution ratio for each single-day control period can be manually adjusted. Among them, the several control periods divided for the heating season, the single-day control period division, etc. can be adjusted; the expression of heat can be parameters such as instantaneous heat, secondary network supply water temperature, secondary network return water temperature, secondary network average supply and return water temperature, heat index, etc.

[0117] Specifically, after obtaining the historical operation data of the heat exchange unit and determining the heat distribution ratio of each regulation period for each regulation time period on a single day according to the historical operation data, the divided regulation periods, each regulation time period on a single day in each regulation period, and the heat distribution ratio of each regulation time period on a single day in each regulation period can be displayed to facilitate relevant personnel to view and send modification instructions, etc. After receiving the modification instructions sent by relevant personnel, at least one of the division of the regulation period, the division of the regulation time period on a single day in the regulation period, and the heat distribution ratio of each regulation time period on a single day in the regulation period can be correspondingly modified according to the modification instructions. Specifically, at least one of the division of the regulation period, the division of the regulation time period on a single day in the regulation period, and the heat distribution ratio of each regulation time period on a single day in the regulation period can be correspondingly modified according to what item is specifically modified in the modification instructions and how the item is specifically modified, so as to facilitate meeting user requirements and improving the user experience and flexibility of the operation regulation of the heat exchange unit.
