Technical Field

[0001] This invention relates to the field of gas emission measurement technology, and in particular to a method, apparatus, equipment, medium, and program product for total emission correction. Background Technology

[0002] In nuclear power plants, the total amount of radioactive gaseous effluent emissions is one of the key indicators for measuring the environmental protection level and safety performance of nuclear power plant operation. Its accurate calculation is highly dependent on the gaseous effluent emission flow meter inside the chimney.

[0003] In actual operation, flow meters are susceptible to various factors, such as malfunctions caused by natural aging of the equipment and the implementation of regular preventive maintenance. These factors can cause flow meters to be unusable for a period of time. Once a flow meter fails in stages, a critical real-time monitoring method for gaseous effluent discharge flow will be lost, thus affecting the determination of the total amount of gaseous effluent discharged from the nuclear power plant. Summary of the Invention

[0004] This invention provides a method, apparatus, equipment, medium, and program product for total emission correction, to solve the problem of being unable to determine the total emission of gaseous effluent when a flow meter experiences a periodic failure.

[0006] The first emission volume of gaseous effluent during a normal period when the total flow meter is in normal condition within the target sampling period is obtained; the target sampling period includes an abnormal period when at least one total flow meter is in abnormal condition.

[0007] Based on the average emission flow rate of each branch during the abnormal period of the target sampling cycle and the duration of the abnormal period, the second emission amount of gaseous effluent during the abnormal period is determined.

[0008] The total amount of gaseous effluent emitted during the target sampling period is determined based on the first emission amount and the second emission amount.

[0009] According to another aspect of the present invention, an emissions correction device is provided, comprising:

[0010] The first emission determination module is used to obtain the first emission of gaseous effluent during a normal period when the total flow meter is in a normal state within the target sampling period; the target sampling period includes at least one abnormal period when the total flow meter is in an abnormal state.

[0011] The second emission determination module is used to determine the second emission amount of gaseous effluent during the abnormal period based on the average emission flow rate of each branch and the duration of the abnormal period during the abnormal period of the target sampling cycle.

[0012] The total emission determination module is used to determine the total emission of gaseous effluent during the target sampling period based on the first emission amount and the second emission amount.

[0016] The memory stores a computer program that can be executed by the at least one processor, the computer program being executed by the at least one processor to enable the at least one processor to perform the total emissions correction method according to any embodiment of the present invention.

[0017] According to another aspect of the present invention, a computer-readable storage medium is provided, the computer-readable storage medium storing computer instructions for causing a processor to execute and implement a total emissions correction method according to any embodiment of the present invention.

[0018] According to another aspect of the present invention, a computer program product is provided, including a computer program that, when executed by a processor, implements a total emissions correction method according to any embodiment of the present disclosure.

[0019] The technical solution of this invention obtains the first emission amount of gaseous effluent during a normal period when the total flow meter is in a normal state within a target sampling period. The target sampling period includes an abnormal period when at least one total flow meter is in an abnormal state. Then, based on the average emission flow rate of each branch and the duration of the abnormal period in the target sampling period, a second emission amount of gaseous effluent during the abnormal period is determined.

[0028] Example 1

[0029] Figure 1The flowchart below provides a method for correcting total emissions according to Embodiment 1 of the present invention. This embodiment is applicable to situations where the total flow meter experiences periodic anomalies. This method can be executed by a total emissions correction device, which can be implemented in hardware and / or software and can be configured in various general-purpose computing devices. Figure 1 As shown, the method includes:

[0030] S110. Obtain the first emission volume of gaseous effluent during the normal period when the total flow meter is in normal condition during the target sampling period; the target sampling period includes an abnormal period when at least one total flow meter is in abnormal condition.

[0031] The target sampling period refers to a sampling period that includes at least one abnormal period in which the total flow meter is in an abnormal state. For example, each sampling period is 7 days. If the total flow meter is in an abnormal state on days 2-3 and days 5-6 within a sampling period, that is, it includes two abnormal periods, then the sampling period is determined to be the target sampling period.

[0032] The total flow meter is a flow meter installed at a designated location on the nuclear power plant's chimney to measure the flow rate and total amount of gaseous effluent emitted from the chimney. If the equipment malfunctions due to natural aging or if routine preventative maintenance renders the total flow meter unusable for a period of time, it will affect the determination of the total amount of gaseous effluent emitted from the nuclear power plant.

[0033] In this embodiment of the invention, to determine the total emission of gaseous effluent during the target sampling period, the target sampling period is divided into two parts: normal periods and abnormal periods. It is worth noting that the normal and abnormal periods within the target sampling period may not be unique. For example, if the total flow meter is in an abnormal state on days 2-3 and 5-6 of the target sampling period, while remaining in a normal state during other periods, then the target sampling period includes three normal periods (days 1-2, 3-5, and 6-7) and two abnormal periods (days 2-3 and 5-6).

[0034] First, the initial emission volume of gaseous effluent during normal periods when the total flow meter is in normal operation within the target sampling period is obtained. Specifically, the emission flow rate for each normal period can be read from the total flow meter. Based on the emission flow rate and duration of each normal period, the emission volume of gaseous effluent for each normal period is determined. Finally, the emission volumes of gaseous effluent for each normal period within the target sampling period are summed to obtain the initial emission volume of gaseous effluent for each normal period. The emission flow rate for each normal period refers to the average emission flow rate within that period.

[0035] Alternatively, the cumulative emissions at the start and end of each normal period can be read from the total flow meter, and the difference between the two can be calculated to obtain the emission amount of gaseous effluent for each normal period. Finally, the gaseous effluent emissions of each normal period in the target sampling period are summed to obtain the first emission amount of gaseous effluent in the normal period.

[0036] Optionally, the total flow meter is a flow meter installed at a designated location on the nuclear power plant's chimney.

[0037] S120. Based on the average emission flow rate of each branch during the abnormal period of the target sampling cycle and the duration of the abnormal period, determine the second emission amount of gaseous effluent during the abnormal period.

[0038] Under normal operating conditions, the exhaust air flow received by the chimney mainly comes from the exhaust air of the non-radioactive ventilation system building. The ventilation system building contains multiple exhaust branches, each equipped with an exhaust flow meter. During abnormal periods, when the total flow meter is malfunctioning and cannot read, the exhaust air flow recorded by the exhaust flow meters of each branch is used to determine the secondary emission volume of gaseous effluent from the chimney during the abnormal period.

[0039] In this embodiment of the invention, for each abnormal period in the target sampling period, the average discharge flow of each branch is first read from the branch exhaust flow meter, and the average discharge flow of multiple branches is summed to obtain the total discharge flow of all branches.

[0040] Furthermore, based on the total emission flow rate and duration of each abnormal period, the emission amount for each abnormal period is determined. The emission amounts for multiple abnormal periods are summed to obtain the second emission amount of gaseous effluent during the abnormal periods in the target sampling cycle.

[0041] S130. Determine the total amount of gaseous effluent emitted during the target sampling period based on the first emission amount and the second emission amount.

[0042] In this embodiment of the invention, the first emission amount is the gaseous effluent emission amount during all normal periods in the target sampling period, and the second emission amount is the gaseous effluent emission amount during all abnormal periods in the target sampling period. By summing the two, the gaseous effluent emission amount in the target sampling period can be determined.

[0043] The technical solution of this invention obtains the first emission amount of gaseous effluent during a normal period when the total flow meter is in a normal state within a target sampling period. The target sampling period includes an abnormal period when at least one total flow meter is in an abnormal state. Then, based on the average emission flow rate of each branch and the duration of the abnormal period in the target sampling period, a second emission amount of gaseous effluent during the abnormal period is determined. Finally, based on the first and second emission amounts, the total emission amount of gaseous effluent in the target sampling period is determined. This method allows for the determination of the total emission amount of gaseous effluent in the target sampling period based on available data when the total flow meter is in an abnormal state.

[0044] Example 2

[0045] Figure 2 This is a flowchart of a total emission correction method provided in Embodiment 2 of the present invention. Based on the above embodiments, this embodiment provides specific steps for obtaining the first emission amount of gaseous effluent during a normal period when the total flow meter is in a normal state within the target sampling period, and specific steps for determining the second emission amount of gaseous effluent during an abnormal period based on the average emission flow rate of each branch and the duration of the abnormal period within the target sampling period. Figure 2 As shown, the method includes:

[0046] S210. Obtain the number of normal time periods included in the target sampling period; the target sampling period includes at least one abnormal time period in which the total flow meter is in an abnormal state.

[0047] In this embodiment of the invention, in order to determine the method for determining the first emission amount, the number of normal time periods included in the target collection cycle is first obtained. The number of normal time periods can be compared with a preset quantity threshold to determine the method for determining the first emission amount.

[0048] S220. When the amount of gaseous effluent during normal periods is less than the quantity threshold, obtain the amount of gaseous effluent emitted during each normal period, and sum the amount of gaseous effluent emitted during each normal period as the first amount of gaseous effluent emitted during the normal period.

[0049] In this embodiment of the invention, when the number of instances during a normal period is less than a threshold, the emission amount of gaseous effluent for each normal period can be directly obtained based on the total flow meter reading. Then, the emission amounts of gaseous effluent for each normal period are summed to obtain the first emission amount of gaseous effluent during the normal period.

[0050] Optionally, obtain the gaseous effluent emissions for each normal time period, including:

[0051] Obtain the total discharge flow rate detected by the flow meter for each normal period, and determine the gaseous effluent discharge volume for each normal period based on the discharge flow rate and the duration of each normal period; or,

[0052] Read the start and end times of each normal period, the cumulative discharge recorded by the total flow meter, and determine the gaseous effluent discharge for each normal period based on the cumulative discharge.

[0053] In this optional embodiment, a specific method is provided for obtaining the gaseous effluent discharge amount for each normal time period: the discharge flow rate detected by the total flow meter for each normal time period can be read, and the discharge flow rate can be multiplied by the duration of each normal time period to obtain the gaseous effluent discharge amount for each normal time period.

[0054] In addition, it can also read the start and end times of each normal period, the cumulative emissions recorded by the total flow meter, and subtract the cumulative emissions at the end and start times to obtain the gaseous effluent emissions for each normal period.

[0055] S230. If the number of normal periods is greater than or equal to the number threshold, obtain the average emission flow rate in the previous normal sampling period that does not include abnormal periods, and determine the first emission amount of gaseous effluent in the normal period based on the average emission flow rate and the total duration of multiple normal periods.

[0056] In this embodiment of the invention, when the number of normal time periods is greater than or equal to a threshold, sequentially reading the total flow meter readings for each time period takes a significant amount of time, thus affecting the efficiency of calculating the first emission amount. To improve calculation efficiency, the average emission flow rate in the previous normal sampling period (excluding abnormal time periods) can be directly obtained, and this average emission flow rate can be multiplied by the total duration of multiple normal time periods to determine the first emission amount of gaseous effluent in the normal time period. This method eliminates the need to sequentially read the total flow meter readings for each normal time period before calculation, greatly improving the calculation efficiency of the first emission amount in the normal time period. Furthermore, using the average emission flow rate in the previous normal sampling period (excluding abnormal time periods) for the calculation of the normal time period in the current cycle ensures calculation accuracy.

[0057] S240. For each abnormal time period in the target sampling period, obtain the average emission flow of each branch during the abnormal time period, and sum the average emission flow of multiple branches to obtain the total emission flow.

[0058] In this embodiment of the invention, after determining the first emission amount during a normal period in the target sampling period, it is necessary to calculate the second emission amount corresponding to the abnormal period. Since there is no total flow meter reading during the abnormal period, the average emission flow rate of each branch is obtained for each abnormal period in the target sampling period. That is, multiple readings of the emission flow meter of the branch are read during the abnormal period, and the average value of the readings is taken as the average emission flow rate of that branch. Then, the average emission flow rates of multiple branches are summed to obtain the total emission flow rate.

[0059] S250. Based on the total emission flow rate and duration of each abnormal period, determine the second emission amount of gaseous effluent during the abnormal period.

[0060] In this embodiment of the invention, the product of the total emission flow rate and the duration of the abnormal period is calculated as the second emission amount of gaseous effluent during the abnormal period.

[0061] S260. Determine the total amount of gaseous effluent emitted during the target sampling period based on the first emission amount and the second emission amount.

[0062] In summary, according to the embodiments of the present invention, the total emission of gaseous effluent during the target sampling period is obtained by summing the first emission amount during the normal period and the second emission amount during the abnormal period. The specific calculation formula for the total emission Q is as follows:

[0063] ;

[0064] in, It is the average emission flow rate during the previous normal sampling period. It is the total duration of multiple normal time periods. It is the first emission volume. It is the sum of the average discharge flow rates of multiple branches during the abnormal period. It is the total duration of multiple abnormal periods. It is the second largest emission.

[0065] Optional, also includes:

[0066] In the absence of a clear abnormal period, the average emission flow rate of each branch in the previous normal sampling period that did not include the abnormal period is obtained, and the first emission estimate of gaseous effluent in the target sampling period is determined based on the average emission flow rate.

[0067] The second emission estimate of the target branch is determined based on the turbine shutdown period of the target branch and the historical emission flow of the target branch during its historical operation.

[0068] Based on the first and second emission estimates, the total amount of gaseous effluent emissions during the target sampling period is determined.

[0069] In this optional embodiment, the total flow meter anomaly includes a fault state and a maintenance state. The maintenance state allows for the acquisition of the start and end times of the abnormal period, while the fault state does not provide an accurate start time. Therefore, when the abnormal period is unclear, the average emission flow rate of each branch in the previous normal sampling period (excluding the abnormal period) is obtained. Then, based on the average emission flow rate and the total duration of the target sampling period, the first estimated emission amount of gaseous effluent in the target sampling period is determined. Specifically, the average emission flow rate of each branch in the previous normal sampling period is summed, and the summation result is multiplied by the total duration of the target sampling period.

[0070] Furthermore, if at least one branch is out of service during the target sampling period, the out-of-service branch is designated as the target branch. The second emission estimate for the target branch is determined based on the turbine outage period of the target branch and its historical emission flow rate during historical operation. The historical emission flow rate can be the average emission flow rate of the target branch during historical operation. Then, based on the historical emission flow rate of the target branch and the duration of the corresponding turbine outage period, the second emission estimate for the target branch is determined. It is worth noting that there can be one or more target branches. When there are multiple target branches, the second emission estimate is the sum of the emissions missing from each of the target branches during its respective outage period.

[0071] Finally, the difference between the first emission estimate and the second emission estimate is used to obtain the total emission of gaseous effluent during the target sampling period. The specific formula for calculating the total emission Q is as follows:

[0072] ;

[0073] in, The sum of the average emission flow rates of multiple branches in the previous normal sampling period that did not include abnormal periods. It is the total duration of the target sampling period. This is the first estimated emission level. It is the historical emission flow of the i-th target branch. It is the downtime of the i-th target branch during the target sampling period. This is the second estimated emission level.

[0074] The technical solution of this invention obtains the first emission amount of gaseous effluent during a normal period when the total flow meter is in a normal state within a target sampling period. The target sampling period includes an abnormal period when at least one total flow meter is in an abnormal state. Then, based on the average emission flow rate of each branch and the duration of the abnormal period in the target sampling period, a second emission amount of gaseous effluent during the abnormal period is determined. Finally, based on the first and second emission amounts, the total emission amount of gaseous effluent in the target sampling period is determined. This method allows for the determination of the total emission amount of gaseous effluent in the target sampling period based on available data when the total flow meter is in an abnormal state.

[0079] The total emission determination module 330 is used to determine the total emission of gaseous effluent during the target sampling period based on the first emission amount and the second emission amount.

[0080] The technical solution of this invention provides that the first emission amount of gaseous effluent during a normal period when the total flow meter is in a normal state within a target sampling period is obtained. The target sampling period includes an abnormal period in which at least one total flow meter is in an abnormal state. Then, based on the average emission flow rate of each branch and the duration of the abnormal period in the target sampling period, the second emission amount of gaseous effluent during the abnormal period is determined.
