[0022] Embodiments of the present disclosure are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be construed as limiting the present disclosure.

[0023] During the operation of a power plant, cooling water temperature regulation is a vital daily task. In order to meet the needs of different tasks, workers usually need to adjust the temperature of the equipment cooling water according to different operating requirements to avoid the equipment temperature being too high or too low, which will affect the service life of the equipment. Traditional cooling water regulation methods require workers to regulate on-site, which makes it impossible to regulate the cooling water temperature in time, and it is impossible to achieve real-time monitoring of the cooling water temperature.

[0024] The present disclosure is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Figure 1 The present invention provides a flow chart of a cooling water temperature adjustment method, which is applied to a distributed control system (DCS). Figure 1 As shown, steps 101-104 are included.

[0026] Step 101, obtaining the cooling water detection temperature.

[0027] In some embodiments, a temperature detection device may be provided at the water inlet of the cooling water, so that the detected temperature of the cooling water may be obtained through the temperature detection device, but this is not limited thereto, and the present disclosure does not limit the method for obtaining the detected temperature of the cooling water.

[0028] In some embodiments, the cooling water detected temperature is the real-time temperature of the cooling water obtained by measuring the temperature of the cooling water.

[0029] Step 102: Generate a deviation indication signal based on the cooling water detection temperature, the preset cooling water detection temperature value, and the preset cooling water temperature difference threshold.

[0030] In some embodiments, the actual cooling water temperature difference is determined by subtracting the cooling water detection temperature from the preset cooling water detection temperature value, and then the actual cooling water temperature difference is numerically compared with the preset cooling water temperature difference threshold to generate a deviation indication signal based on the comparison result.

[0031] In some embodiments, the deviation indication signal may include: a first deviation indication signal and a second deviation indication signal.

[0032] Specifically, when the actual cooling water temperature difference is within the preset cooling water temperature difference threshold range, a first deviation indication signal is generated; when the actual cooling water temperature difference is outside the preset cooling water temperature difference threshold range, a second deviation indication signal is generated.

[0033] In an optional embodiment, a deviation indication signal can be generated by setting a differential (DEV) module in the DCS system, wherein the cooling water detection temperature is the input of the DEV module, and the preset cooling water detection temperature value and the preset cooling water temperature difference threshold are preset parameters of the DEV module. When the DEV module determines through differential and comparison that the actual cooling water temperature difference is within the preset cooling water temperature difference threshold range, the DEV module can output a high-level signal, thereby realizing the generation of a first deviation indication signal; when the DEV module determines through differential and comparison that the actual cooling water temperature difference is outside the preset cooling water temperature difference threshold range, it can output a low-level signal, thereby realizing the generation of a second deviation indication signal.

[0034] Step 103: generating a cooling water temperature adjustment indication signal based on the deviation indication signal.

[0035] In some embodiments, different cooling water temperature adjustment indication signals may be generated according to different types of deviation indication signals.

[0036] Specifically, when the deviation indication signal is a first deviation indication signal, based on the first deviation indication signal, a proportional integral differential control PID algorithm is used to generate a first cooling water temperature adjustment indication signal, the first cooling water temperature adjustment indication signal includes opening adjustment information of the cooling water temperature control valve, and the first cooling water temperature adjustment indication signal is used to indicate that the cooling water temperature control valve is adjusted to the opening indicated in the opening adjustment information;

[0037] When the deviation indication signal is the second deviation indication signal, it means that the current cooling water temperature is greatly different from the expected temperature. At this time, based on the second deviation indication signal, a second cooling water temperature adjustment indication signal is generated to adjust the opening of the cooling water temperature control valve to a preset opening, thereby performing a preliminary adjustment on the cooling water temperature. In other words, the second cooling water temperature adjustment indication signal is used to indicate that the cooling water temperature control valve is adjusted to a preset opening.

[0038] Step 104: Based on the cooling water temperature adjustment indication signal, adjust the opening of the cooling water temperature adjustment valve to adjust the cooling water temperature.

[0039] In some embodiments, the opening degree of the cooling water temperature regulating valve to be adjusted can be determined according to the cooling water temperature adjustment indication signal, and the cooling water temperature regulating valve can be adjusted according to the opening degree to achieve cooling water temperature adjustment.

[0040] Specifically, when the cooling water temperature adjustment indication signal is the first cooling water temperature adjustment indication signal, the opening of the cooling water temperature adjustment valve may be adjusted based on the opening adjustment information contained in the first cooling water temperature adjustment indication signal to adjust the cooling water temperature;

[0041] When the cooling water temperature adjustment indication signal is the second cooling water temperature adjustment indication signal, the opening of the cooling water temperature adjustment valve is adjusted to a preset opening to adjust the cooling water temperature.

[0042] In summary, the cooling water temperature regulation method proposed in the present disclosure is applied to the distributed control system DCS, and the method includes: obtaining the cooling water detection temperature; generating a deviation indication signal based on the cooling water detection temperature, a preset cooling water detection temperature value, and a preset cooling water temperature difference threshold; generating a cooling water temperature regulation indication signal based on the deviation indication signal; adjusting the opening of the cooling water temperature regulating valve based on the cooling water temperature regulation indication signal to regulate the cooling water temperature. The method disclosed in the present disclosure remotely monitors the relevant parameters of the cooling water through the DCS, so that the opening of the cooling water temperature regulating valve can be adjusted according to the actual production needs to achieve the regulation of the cooling water temperature, and the cooling water temperature state can be better grasped to achieve automatic adjustment of the cooling water temperature.

[0043] Figure 2 The present invention further shows a flow chart of a cooling water temperature regulation method, which is applied to a DCS system. Figure 1 The embodiment shown, Figure 2 The following steps are included.

[0044] Step 201, obtaining the cooling water detection temperature.

[0045] In some embodiments, the principle of step 201 is the same as that of the embodiment shown in step 101, and reference may be made to the above related description, which will not be repeated here.

[0046] Step 202: Subtract the cooling water detection temperature from the preset cooling water detection temperature value to obtain the actual cooling water temperature difference.

[0047] In some embodiments, the actual cooling water temperature difference is determined by subtracting the cooling water detection temperature from the preset cooling water detection temperature value, laying the foundation for generating a deviation indication signal, wherein the preset cooling water detection temperature value can be set and stored in a module for performing the subtraction action.

[0048] Step 203: When the actual cooling water temperature difference is within a preset cooling water temperature difference threshold range, a first deviation indication signal is generated.

[0049] In some embodiments, when the actual cooling water temperature difference is within a preset cooling water temperature difference threshold range, a first deviation indication signal is generated.

[0050] Optionally, in the DCS system, the module for generating the first deviation indication signal may be the same module as the module for determining the actual cooling water temperature difference.

[0051] Optionally, a first deviation indication signal can be generated by setting a differential (DEV) module in the DCS system, wherein the cooling water detection temperature is the input of the DEV module, and the preset cooling water detection temperature value and the preset cooling water temperature difference threshold are preset parameters of the DEV module. When the DEV module determines through differential and comparison that the actual cooling water temperature difference is within the preset cooling water temperature difference threshold range, the DEV module can output a high-level signal, thereby realizing the generation of the first deviation indication signal.

[0052] Step 204 : when the deviation indication signal is a first deviation indication signal, based on the first deviation indication signal, a proportional integral differential control PID algorithm is used to generate a first cooling water temperature adjustment indication signal.

[0053] In some embodiments, when the deviation indication signal is a first deviation indication signal, the cooling water detection temperature of the current temperature adjustment round and the output of the PID algorithm in the previous temperature adjustment round can be used as inputs of the PID algorithm of the current temperature adjustment round. The opening adjustment information of the cooling water temperature control valve is determined by the PID algorithm, and a first cooling water temperature adjustment indication signal is generated to carry the opening adjustment information.

[0054] In other words, the opening adjustment information includes the desired opening that the system desires the cooling water temperature control valve to adjust.

[0055] In some embodiments, the parameters of the PID algorithm may be manually set or automatically extracted from a database, which is not limited in the present disclosure.

[0056] Step 205: obtaining the actual opening degree of the cooling water temperature regulating valve based on the indication signal.

[0057] In some embodiments, due to the long service life of the cooling water temperature control valve and information loss during the transmission of the indication signal, there is usually a certain error between the actual opening of the cooling water temperature control valve and the expected opening corresponding to the opening adjustment information.

[0058] Therefore, the opening degree of the cooling water temperature control valve after adjustment can be corrected by acquiring the actual opening degree of the cooling water temperature control valve based on the instruction signal.

[0059] Step 206 : generating a correction instruction signal based on the actual opening and the opening adjustment information indicated by the adjustment instruction signal.

[0060] In some embodiments, the opening degree that needs to be corrected can be determined by subtracting the opening degree indicated in the opening adjustment information from the actual opening degree, thereby generating a correction indication signal. In other words, the correction indication signal is used to indicate the opening degree that needs to be corrected for the cooling water temperature control valve.

[0061] Step 207, based on the correction instruction signal, correct the opening of the adjusted cooling water temperature control valve.

[0062] In some embodiments, the opening of the cooling water temperature regulating valve adjusted according to the indication signal can be corrected by correcting the opening size that needs to be corrected indicated in the correction indication signal, so as to further improve the accuracy of cooling water temperature regulation.

[0063] In summary, the cooling water temperature regulation method proposed in the present disclosure is applied to a distributed control system DCS, and the method includes: obtaining the cooling water detection temperature; subtracting the cooling water detection temperature from the preset cooling water detection temperature value to obtain the actual cooling water temperature difference; when the actual cooling water temperature difference is within the preset cooling water temperature difference threshold range, generating a first deviation indication signal; when the deviation indication signal is the first deviation indication signal, based on the first deviation indication signal, using a proportional integral differential control PID algorithm to generate a first cooling water temperature regulation indication signal; when the cooling water temperature regulation indication signal is the first cooling water temperature regulation indication signal, based on the opening adjustment information, adjusting the opening of the cooling water temperature regulating valve to adjust the cooling water temperature; obtaining the actual opening of the cooling water temperature regulating valve based on the indication signal; generating a correction indication signal based on the actual opening and the opening adjustment information or / preset opening indicated by the adjustment indication signal; and correcting the opening of the adjusted cooling water temperature regulating valve based on the correction indication signal. The method disclosed in the present invention remotely monitors the relevant parameters of cooling water through DCS, so that the opening of the cooling water temperature regulating valve can be adjusted according to the actual production needs to achieve the adjustment of the cooling water temperature, and the cooling water temperature state can be better grasped to achieve automatic adjustment of the cooling water temperature; and by obtaining the feedback of the cooling water temperature regulating valve after receiving the adjustment indication signal (i.e., the correction indication signal), the opening of the cooling water temperature regulating valve adjusted according to the indication signal is corrected to further improve the accuracy of cooling water temperature regulation.

[0064] Figure 3 The present invention further shows a flow chart of a cooling water temperature regulation method, which is applied to a DCS system. Figure 1 The embodiment shown, Figure 3 The following steps are included.

[0065] Step 301, obtaining the cooling water detection temperature.

[0066] In some embodiments, the principle of step 301 is the same as that of the embodiment shown in step 101, and reference may be made to the above related description, which will not be repeated here.

[0067] Step 302: Subtract the cooling water detection temperature from the preset cooling water detection temperature value to obtain the actual cooling water temperature difference.

[0068] In some embodiments, the principle of step 302 is the same as that of the embodiment shown in step 102, and reference may be made to the above related description, which will not be repeated here.

[0069] Step 303: When the actual cooling water temperature difference is outside the preset cooling water temperature difference threshold range, a second deviation indication signal is generated.

[0070] In some embodiments, when the actual cooling water temperature difference is outside a preset cooling water temperature difference threshold range, a second deviation indication signal is generated.

[0071] Optionally, in the DCS system, the module for generating the second deviation indication signal may be the same module as the module for determining the actual cooling water temperature difference.

[0072] Optionally, a first deviation indication signal can be generated by setting a differential (DEV) module in the DCS system, wherein the cooling water detection temperature is the input of the DEV module, and the preset cooling water detection temperature value and the preset cooling water temperature difference threshold are preset parameters of the DEV module. When the DEV module determines through differential and comparison that the actual cooling water temperature difference is outside the preset cooling water temperature difference threshold range, the DEV module can output a low-level signal, thereby realizing the generation of a second deviation indication signal.

[0073] Step 304, obtaining historical cooling water detection temperature.

[0074] In some embodiments, in order to avoid the obtained cooling water detection temperature being abnormal, thereby causing the generated deviation indication signal to be the first deviation indication signal, it is also possible to obtain historical cooling water detection temperatures to determine whether the cooling water detection temperature is abnormal.

[0075] In some embodiments, the module for acquiring the cooling water detection temperature has a storage function, which can store the cooling water detection temperature acquired each time, so as to acquire the historical cooling water detection temperature by accessing the module for acquiring the cooling water detection temperature.

[0076] In some embodiments, the module for obtaining the cooling water detection temperature may upload each obtained cooling water detection temperature to a database, and then obtain the historical cooling water detection temperature by accessing the database.

[0077] In other words, the historical cooling water detection temperature is the cooling water detection temperature obtained before the current cooling water temperature is adjusted.

[0078] Step 305 : determining whether the cooling water detection temperature is abnormal based on the historical cooling water detection temperature and / or the cooling water detection temperature abnormality threshold.

[0079] In some embodiments, the cooling water detection temperature can be compared with the historical cooling water detection temperature. When the difference between the historical cooling water detection temperature and the cooling water detection temperature is greater than a preset value, it can be determined that the cooling water detection temperature is abnormal.

[0080] In some embodiments, a cooling water detection temperature abnormality threshold may be set. When the cooling water detection temperature exceeds the cooling water detection temperature abnormality threshold, it may be determined that the cooling water detection temperature is abnormal.

[0081] In some embodiments, when there is an abnormality in the cooling water detection temperature, an abnormal alarm signal can be generated to notify the staff that there is an abnormality in the cooling water detection temperature and the detection equipment needs to be checked.

[0082] Step 306 , when the cooling water temperature adjustment indication signal is the second cooling water temperature adjustment indication signal, adjusting the opening of the cooling water temperature adjustment valve to a preset opening to adjust the cooling water temperature.

[0083] In some embodiments, when the deviation indication signal is a second deviation indication signal, a second cooling water temperature adjustment indication signal may be generated based on the second deviation indication signal to instruct the cooling water temperature adjustment valve to adjust the opening to a preset opening.

[0084] Step 307: obtaining the actual opening degree of the cooling water temperature regulating valve based on the indication signal.

[0085] Step 308: Generate a correction indication signal based on the actual opening and the opening adjustment information indicated by the adjustment indication signal.

[0086] Step 309: Correct the opening of the cooling water temperature control valve after adjustment based on the correction instruction signal.

[0087] In some embodiments, the principles of steps 307-309 are the same as those of the embodiment shown in steps 205-207, and reference may be made to the above related descriptions, which will not be repeated here.

[0088] In summary, according to the cooling water temperature regulation method proposed in the present disclosure, it is applied to a distributed control system DCS, and the method includes: obtaining the cooling water detection temperature; subtracting the cooling water detection temperature from the preset cooling water detection temperature value to obtain the actual cooling water temperature difference; when the actual cooling water temperature difference is outside the preset cooling water temperature difference threshold range, generating a second deviation indication signal; obtaining the historical cooling water detection temperature; based on the historical cooling water detection temperature and / or the cooling water detection temperature abnormality threshold, determining whether the cooling water detection temperature is abnormal; when the cooling water detection temperature is abnormal, generating an abnormal alarm signal; when the deviation indication signal is the second deviation indication signal, generating a second cooling water temperature adjustment indication signal based on the second deviation indication signal; when the cooling water temperature adjustment indication signal is the second cooling water temperature adjustment indication signal, adjusting the opening of the cooling water temperature regulating valve to the preset opening to adjust the cooling water temperature; obtaining the actual opening of the cooling water temperature regulating valve based on the indication signal; generating a correction indication signal based on the actual opening and the opening adjustment information or / preset opening indicated by the adjustment indication signal; and correcting the opening of the adjusted cooling water temperature regulating valve based on the correction indication signal. The method disclosed in the present invention remotely monitors the relevant parameters of cooling water through DCS, so that the opening of the cooling water temperature regulating valve can be adjusted according to the actual production needs to achieve the adjustment of the cooling water temperature, and the cooling water temperature state can be better grasped to achieve automatic adjustment of the cooling water temperature; and by obtaining the feedback of the cooling water temperature regulating valve after receiving the adjustment indication signal (i.e., the correction indication signal), the opening of the cooling water temperature regulating valve adjusted according to the indication signal is corrected to further improve the accuracy of cooling water temperature regulation.

[0089] Therefore, this solution has the following beneficial effects:

[0091] Furthermore, by obtaining feedback (i.e., correcting the indication signal) from the cooling water temperature regulating valve after receiving the adjustment indication signal, the opening of the cooling water temperature regulating valve adjusted according to the indication signal is corrected to further improve the accuracy of cooling water temperature regulation.
