[0055] Embodiments of the present application 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 application, and should not be construed as limiting the present application.

[0056] It should be noted that in the field of steam and water quality analysis in thermal power plants, the replacement of failed cation exchange resins is often organized and arranged by the thermal control professionals, and the on-duty operators are usually not notified. In the process of replacing the resin, the measurement results of the hydrogen conductivity meter are inaccurate, which affects the observation of the on-duty operators on the host computer and the judgment of the on-duty operators. At the least, it increases the communication cost of the team members, and at the worst, it causes wrong operations under wrong analysis, which not only affects the safe and stable operation of the unit, but also affects the accuracy and development progress of the model analysis in the process of big data analysis and mining. Therefore, how to accurately identify whether the hydrogen conductivity meter is in the process of replacing the resin has become an urgent problem to be solved.

[0057] In order to solve the above problems, the present application provides a method and device for monitoring the hydrogen conductivity resin exchange process.

[0058] Figure 1This is a flow chart of a method for monitoring a hydrogen conductivity meter resin exchange process provided in an embodiment of the present application. It should be noted that the method for monitoring a hydrogen conductivity meter resin exchange process in the embodiment of the present application can be used in the monitoring device for the hydrogen conductivity meter resin exchange process in the embodiment of the present application, and the monitoring device for the hydrogen conductivity meter resin exchange process in the embodiment of the present application can be configured in an electronic device. Figure 1 As shown, the method may include the following steps:

[0059] Step 101, obtaining the unit load at the current moment.

[0060] In some embodiments of the present application, the unit load at the current moment refers to the load of the thermal power unit at the current moment. It can be understood that when the unit load is greater than the preset load threshold, the thermal power unit can be considered to be in normal operation to avoid misjudgment of the hydrogen conductivity meter resin replacement process due to the impact of the start-up and shutdown process on the hydrogen conductivity.

[0061] Step 102, in response to the unit load being greater than a preset load threshold, the hydrogen conductivity of the condensate outlet, the deaerator inlet, the economizer inlet, and the left and right sides of the main steam are respectively obtained at the current time and the past time.

[0062] In some embodiments of the present application, the hydrogen conductivity at the past moment may be a moment before the current moment, such as 5 seconds before the current moment, etc. Respectively obtaining the hydrogen conductivity of the condensate outlet, the deaerator inlet, the economizer inlet, and the left and right sides of the main steam at the current moment and the past moment, refers to obtaining the hydrogen conductivity of the condensate outlet at the current moment and the hydrogen conductivity at the past moment, obtaining the hydrogen conductivity of the deaerator inlet at the current moment and the hydrogen conductivity at the past moment, obtaining the hydrogen conductivity of the economizer inlet at the current moment and the hydrogen conductivity at the past moment, and obtaining the hydrogen conductivity of the left and right sides of the main steam at the current moment and the hydrogen conductivity at the past moment.

[0063] It should be noted that the hydrogen conductivity of the condensate outlet at the past time, the hydrogen conductivity of the deaerator inlet at the past time, the hydrogen conductivity of the economizer inlet at the past time, and the hydrogen conductivity of the left and right sides of the main steam at the past time may be the same time, or may be different times before the current time. As an example, if the current time is 8:03:12, the hydrogen conductivity of the condensate outlet at the past time may be the hydrogen conductivity of the condensate outlet at 8:03:06, the hydrogen conductivity of the deaerator inlet at the past time may be the hydrogen conductivity of the deaerator inlet at 8:03:07, the hydrogen conductivity of the economizer inlet at the past time may be the hydrogen conductivity of the economizer inlet at 8:03:08, and the hydrogen conductivity of the left and right sides of the main steam at the past time may be the hydrogen conductivity of the left and right sides of the main steam at 8:03:06.

[0064] In some embodiments of the present application, the hydrogen conductivity of the condensate outlet, oxygen removal inlet, economizer inlet and the left and right sides of the main steam at the current moment can be obtained by collecting the measurement data of the corresponding hydrogen conductivity meter at the current moment. The hydrogen conductivity of the condensate outlet, oxygen removal inlet, economizer inlet and the left and right sides of the main steam at the past moment can be obtained by connecting the measurement data of the corresponding hydrogen conductivity meter by a hysteresis block.

[0065] Step 103, based on the hydrogen conductivity of the condensate outlet, the deaerator inlet, the economizer inlet, and the left and right sides of the main steam at the current moment and the past moment, determine whether the cation exchange columns of the condensate outlet, the deaerator inlet, the economizer inlet and the left and right sides of the main steam are in the resin replacement process at the current moment.

[0066] It can be understood that when the thermal power unit is measuring the hydrogen conductivity meter, it is necessary to install a cation exchange column in front of the conductivity meter to replace the cations in the water vapor, so that the cations in the water vapor are exchanged by the hydrogen ions in the exchange column, and the water sample passing through the exchange column retains the anions and the exchanged hydrogen ions to achieve the measurement of hydrogen conductivity. When the cation exchange column fails, the relevant staff usually replaces the resin, but during the process of replacing the resin of the cation exchange column, the measurement data of the corresponding hydrogen conductivity meter will suddenly change, so it can be determined whether the measurement data of the corresponding hydrogen conductivity meter has suddenly changed according to the hydrogen conductivity at the current moment and the hydrogen conductivity at the past moment, so as to determine whether the corresponding cation exchange column is in the process of replacing the resin at the current moment.

[0067] In some embodiments of the present application, the hydrogen conductivity thresholds at various locations and the hydrogen conductivity difference thresholds between the current moment and the past moment can be set to determine whether the cation exchange column at each location is in the resin replacement process at the current moment. As an example, the hydrogen conductivity of the condensate outlet at the current moment and the past moment can be subtracted to obtain a first hydrogen conductivity difference, the hydrogen conductivity of the condensate outlet at the current moment is compared with the first hydrogen conductivity threshold, and the first hydrogen conductivity difference is compared with the first difference threshold. If the hydrogen conductivity of the condensate outlet at the current moment is greater than the first hydrogen conductivity threshold, and the first hydrogen conductivity difference is greater than the first difference threshold, it can be determined that the cation exchange resin at the condensate outlet is in the resin replacement process at the current moment.

[0068] In other embodiments of the present application, since there is a connection relationship between the condensate outlet, the deaerator inlet, the economizer inlet and the left and right sides of the main steam, in order to improve the accuracy of the judgment, the results of the upstream and downstream can be combined for judgment. As an example, since there is an upstream and downstream relationship between the condensate outlet and the deaerator inlet and the left and right sides of the main steam, it can be determined whether the hydrogen conductivity of the condensate outlet, the deaerator inlet and the left and right sides of the main steam has a sudden change according to the hydrogen conductivity of the condensate outlet, the deaerator inlet and the left and right sides of the main steam at the current moment and the past moment; if the hydrogen conductivity of the condensate outlet has a sudden change, and the hydrogen conductivity of the deaerator inlet and the left and right sides of the main steam has not changed suddenly, it can be determined that the cation exchange column of the condensate outlet is in the process of changing resin at the current moment; if the hydrogen conductivity of the condensate outlet, the deaerator inlet and the left and right sides of the main steam has a sudden change, it may be due to the sudden change of hydrogen conductivity caused by water quality changes, so it is impossible to determine whether the corresponding cation exchange column is in the process of changing resin.

[0069] In some other embodiments of the present application, the hydrogen conductivity change rate can also be calculated based on the hydrogen conductivity of each position at the current moment and the hydrogen conductivity at the past moment. If the hydrogen conductivity of a certain position at the current moment is greater than a preset hydrogen conductivity threshold, and the hydrogen conductivity change rate of the position is also greater than the preset change rate threshold, and at the same time, the current hydrogen conductivity and hydrogen conductivity change rate at other positions are not greater than the corresponding thresholds at the same time, then it can be determined that the cation exchange resin at the position is in the process of resin replacement at the current moment.

[0070] According to the monitoring method of the resin replacement process of the hydrogen conductivity meter in the embodiment of the present application, when the unit load at the current moment is greater than the preset load threshold, the hydrogen conductivities of the condensate outlet, deaerator inlet, economizer inlet, and the left and right sides of the main steam at the current moment and the past moment are obtained respectively, and based on these hydrogen conductivities, it is determined whether the cation exchange columns of the condensate outlet, deaerator inlet, economizer inlet and the left and right sides of the main steam are in the resin replacement process at the current moment. This can achieve accurate identification of whether the hydrogen conductivity meter is in the resin replacement process, so as to avoid misjudgment of the hydrogen conductivity meter measurement results by on-duty operating personnel. This can not only reduce the communication costs of the staff, but also ensure the safe and stable operation of the unit, while also improving the accuracy of model analysis based on the hydrogen conductivity meter measurement data.

[0071] In order to introduce the implementation process of the above embodiment in detail, the present application proposes another embodiment.

[0072] Figure 2 This is a flow chart for determining whether each cation exchange resin is in the resin replacement process at the current moment in the embodiment of the present application. Figure 2 As shown, Figure 1The implementation of step 103 in may include the following steps:

[0073] Step 201, determining a first change rate according to the hydrogen conductivity of the condensate outlet at the current moment and the past moment.

[0074] In some embodiments of the present application, the hydrogen conductivity of the condensate outlet at the current moment may be subtracted from the hydrogen conductivity of the condensate outlet at the past moment, and the first rate of change may be determined based on the difference between the two. As an example, if the hydrogen conductivity of the condensate outlet at the current moment t is A, and the hydrogen conductivity of the condensate outlet at the past moment t1 is B, then the first rate of change = (AB) / (t-t1).

[0075] Step 202, determining a second change rate according to the hydrogen conductivity at the deaerator inlet at the current time and the past time.

[0076] In some embodiments of the present application, the hydrogen conductivity at the deaerator inlet at the current moment may be subtracted from the hydrogen conductivity at the deaerator inlet at the past moment, and the second change rate may be determined based on the difference between the two.

[0077] Step 203, determining a third change rate according to the hydrogen conductivity at the economizer inlet at the current moment and the past moment.

[0078] In some embodiments of the present application, the hydrogen conductivity at the economizer inlet at the current moment may be subtracted from the hydrogen conductivity at the economizer inlet at the past moment, and the third change rate may be determined based on the difference between the two.

[0079] Step 204, determining a fourth change rate according to the hydrogen conductivity of the left and right sides of the main steam at the current moment and the past moment.

[0080] In some embodiments of the present application, the hydrogen conductivity of the left and right sides of the main steam at the current moment may be subtracted from the hydrogen conductivity of the left and right sides of the main steam at the past moment, and the fourth change rate may be determined based on the difference between the two.

[0081] Step 205, according to the hydrogen conductivity, the first change rate, the second change rate, the third change rate and the fourth change rate of the condensate outlet, the deaerator inlet, the economizer inlet and the left and right sides of the main steam respectively at the current moment, determine whether the cation exchange columns of the condensate outlet, the deaerator inlet, the economizer inlet and the left and right sides of the main steam are in the resin replacement process at the current moment.

[0082] In some embodiments of the present application, it can be determined whether the hydrogen conductivity of the condensate outlet has a sudden change according to the hydrogen conductivity of the condensate outlet at the current moment and the first rate of change. It is determined whether the hydrogen conductivity of the deaerator inlet has a sudden change according to the hydrogen conductivity of the deaerator inlet at the current moment and the second rate of change. It is determined whether the hydrogen conductivity of the economizer inlet has a sudden change according to the hydrogen conductivity of the economizer inlet at the current moment and the third rate of change. It is determined whether the hydrogen conductivity of the left and right sides of the main steam has a sudden change according to the hydrogen conductivity of the left and right sides of the main steam at the current moment and the fourth rate of change. If the hydrogen conductivity of the condensate outlet has a sudden change, and the hydrogen conductivity of the deaerator inlet and the left and right sides of the main steam have not changed, it means that the cation exchange column of the condensate outlet is in the process of changing resin at the current moment. If the hydrogen conductivity of the deaerator inlet has a sudden change, and the hydrogen conductivity of the condensate outlet and the economizer inlet have not changed, it means that the cation exchange column of the deaerator inlet is in the process of changing resin at the current moment. If the hydrogen conductivity at the economizer inlet changes suddenly, while the hydrogen conductivity at the left and right sides of the main steam and the deaerator inlet do not change suddenly, it means that the cation exchange column at the economizer inlet is in the process of changing resin at the current moment. If the hydrogen conductivity at the left and right sides of the main steam changes suddenly, while the hydrogen conductivity at the condensate outlet and the economizer inlet do not change suddenly, it means that the cation exchange columns at the left and right sides of the main steam are in the process of changing resin at the current moment.

[0083] In other embodiments of the present application, it is determined whether the hydrogen conductivity at each position has a sudden change, and it is also possible to determine whether the hydrogen conductivity at the corresponding position meets the state of the resin replacement process based on the hydrogen conductivity and hydrogen conductivity change rate at the corresponding position at the current moment. The state of the resin replacement process can be the state of the measurement result of the corresponding hydrogen conductivity meter when the cation exchange resin is in the resin replacement process. The implementation process of step 205 may include the following steps:

[0084] Step 205-1, according to the hydrogen conductivity of the condenser outlet, deaerator inlet, economizer inlet and the left and right sides of the main steam at the current moment, the first change rate, the second change rate, the third change rate and the fourth change rate, determine whether the hydrogen conductivity of the condensate outlet, the deaerator inlet, the economizer inlet and the left and right sides of the main steam meet the status of the resin replacement process.

[0085] In some embodiments of the present application, the implementation process of this step can be to compare the current hydrogen conductivity and change rate of each position with the corresponding threshold value. If the current hydrogen conductivity and change rate of a certain position are both greater than the corresponding threshold value, it means that the hydrogen conductivity at this position meets the state of the resin replacement process.

[0086] As an implementation method, the hydrogen conductivity at the condensate outlet at the current moment can be compared with the preset first hydrogen conductivity threshold, and the first change rate can be compared with the preset first rate threshold; the hydrogen conductivity at the deaerator inlet at the current moment can be compared with the preset second hydrogen conductivity threshold, and the second change rate can be compared with the preset second rate threshold; the hydrogen conductivity at the economizer inlet at the current moment can be compared with the preset third hydrogen conductivity threshold, and the third change rate can be compared with the preset third rate threshold; the hydrogen conductivity on the left and right sides of the main steam at the current moment can be compared with the preset fourth hydrogen conductivity threshold, and the fourth change rate can be compared with the preset fourth rate threshold; and based on the comparison results, it is determined whether the hydrogen conductivity at each position meets the state of the resin replacement process.

[0087] Among them, based on the comparison results, the implementation method of determining whether the hydrogen conductivity at each position meets the state of the resin replacement process may include: in response to the hydrogen conductivity of the condensate outlet at the current moment being greater than the first hydrogen conductivity threshold and the first change rate being greater than the first rate threshold, determining that the hydrogen conductivity at the condensate outlet meets the state of the resin replacement process; in response to the hydrogen conductivity at the deaerator inlet at the current moment being greater than the second hydrogen conductivity threshold and the second change rate being greater than the second rate threshold, determining that the hydrogen conductivity at the deaerator inlet meets the state of the resin replacement process; in response to the hydrogen conductivity at the economizer inlet at the current moment being greater than the third hydrogen conductivity threshold and the third change rate being greater than the third rate threshold, determining that the hydrogen conductivity at the economizer inlet meets the state of the resin replacement process; in response to the hydrogen conductivity on the left and right sides of the main steam at the current moment being greater than the fourth hydrogen conductivity threshold and the fourth change rate being greater than the fourth rate threshold, determining that the hydrogen conductivity on the left and right sides of the main steam meets the state of the resin replacement process.

[0088] Step 205-2, in response to the fact that the hydrogen conductivity at the condensate outlet meets the state of the resin replacement process, and the hydrogen conductivity at the deaerator inlet and the left and right sides of the main steam do not meet the state of the resin replacement process, it is determined that the cation exchange column at the condensate outlet is in the resin replacement process at the current moment.

[0089] It can be understood that if the hydrogen conductivity at the condensate outlet meets the state of the resin replacement process, it means that the cation exchange column at the condensate outlet may be in the resin replacement state at the current moment, but it may also be due to the change in hydrogen conductivity caused by the change in water quality. Since the deaerator inlet and the left and right sides of the main steam are the upstream and downstream of the condensate outlet, if the hydrogen conductivity at the condensate outlet meets the state of the resin replacement process, and the hydrogen conductivity at the deaerator inlet and the left and right sides of the main steam do not meet the state of the resin replacement process, the possibility of water quality change can be ruled out, that is, it can be determined that the cation exchange column at the condensate outlet is in the resin replacement state at the current moment.

[0090] Step 205-3, in response to the hydrogen conductivity at the deaerator inlet satisfying the state of the resin replacement process, while the hydrogen conductivities at the condensate outlet and the economizer inlet do not satisfy the state of the resin replacement process, it is determined that the cation exchange column at the deaerator inlet is in the resin replacement process at the current moment.

[0091] It can be understood that if the hydrogen conductivity at the deaerator inlet meets the state of the resin replacement process, it means that the cation exchange column at the deaerator inlet may be in the resin replacement state at the current moment, but it may also be due to the change in hydrogen conductivity caused by the change in water quality. Since the condensate outlet and the economizer inlet are upstream and downstream of the deaerator inlet, if the hydrogen conductivity at the deaerator inlet meets the state of the resin replacement process, and the hydrogen conductivity at the condensate outlet and the economizer inlet do not meet the state of the resin replacement process, the possibility of water quality change can be ruled out, that is, it can be determined that the cation exchange column at the deaerator inlet is in the resin replacement state at the current moment.

[0092] Step 205-4, in response to the fact that the hydrogen conductivity at the economizer inlet meets the state of the resin replacement process, and the hydrogen conductivity at the deaerator inlet and the left and right sides of the main steam do not meet the state of the resin replacement process, it is determined that the cation exchange column at the economizer inlet is in the resin replacement process at the current moment.

[0093] It can be understood that if the hydrogen conductivity at the economizer inlet meets the state of the resin replacement process, it means that the cation exchange column at the economizer inlet may be in the resin replacement state at the current moment, but it may also be due to the change in hydrogen conductivity caused by the change in water quality. Since the deaerator inlet and the left and right sides of the main steam are the upstream and downstream of the economizer inlet, if the hydrogen conductivity at the economizer inlet meets the state of the resin replacement process, and the hydrogen conductivity at the deaerator inlet and the left and right sides of the main steam do not meet the state of the resin replacement process, the possibility of water quality change can be ruled out, that is, it can be determined that the cation exchange column at the economizer inlet is in the resin replacement state at the current moment.

[0094] Step 205-5, in response to the hydrogen conductivity on the left and right sides of the main steam satisfying the state of the resin replacement process, while the hydrogen conductivity at the condensate outlet and the economizer inlet does not satisfy the state of the resin replacement process, it is determined that the cation exchange columns on the left and right sides of the main steam are in the resin replacement process at the current moment.

[0095] It can be understood that if the hydrogen conductivity on the left and right sides of the main steam meets the state of the resin replacement process, it means that the cation exchange columns on the left and right sides of the main steam may be in the resin replacement state at the current moment, but it may also be due to the change in hydrogen conductivity caused by the change in water quality. Since the condensate outlet and the economizer inlet are the upstream and downstream of the left and right sides of the main steam, if the hydrogen conductivity on the left and right sides of the main steam meets the state of the resin replacement process, and the hydrogen conductivity at the condensate outlet and the economizer inlet does not meet the state of the resin replacement process, the possibility of water quality change can be ruled out, that is, it can be determined that the cation exchange columns on the left and right sides of the main steam are in the resin replacement state at the current moment.

[0096] According to the monitoring method of the resin replacement process of the hydrogen conductivity meter of the embodiment of the present application, the corresponding change rate can be determined by the hydrogen conductivity of the condensate outlet, the deaerator inlet, the economizer inlet, and the left and right sides of the main steam at the current moment and the past moment, and according to the hydrogen conductivity and corresponding change rate of the condensate outlet, the deaerator inlet, the economizer inlet, and the left and right sides of the main steam at the current moment, it is determined whether the hydrogen conductivity of the condensate outlet, the deaerator inlet, the economizer inlet, and the left and right sides of the main steam meet the state of the resin replacement process, and combined with the upstream and downstream relationships, it is determined whether the cation exchange resins of the condensate outlet, the deaerator inlet, the economizer inlet, and the left and right sides of the main steam are in the resin replacement process. This scheme can determine whether the corresponding cation exchange column is in the resin replacement state according to the hydrogen conductivity and change rate of each position, and combined with the upstream and downstream relationships, so as to not only improve the accuracy of the judgment, but also further ensure the safe and stable operation of the unit.
