Description

Technical Field

[0001] The invention relates to the technical field of reactor uncertainty analysis, and is a universal interface method suitable for uncertainty analysis of a reactor analysis program. Background Art

[0002] Uncertainty analysis of reactors can quantify the impact of uncertain input parameters on output parameters, reduce redundancy in reactor design, and improve the economy of reactors while ensuring reactor safety. Statistical analysis methods based on sampling have the advantages of good flexibility and have been widely used, becoming one of the mainstream analysis methods for uncertainty analysis.

[0003] The basic process of uncertainty analysis based on statistical analysis methods is to substitute the input parameters obtained by sampling into the reactor analysis program, and extract the output parameters of interest after calculation for uncertainty analysis. Therefore, realizing data exchange between the input parameters and output parameters between the reactor analysis program and the uncertainty analysis program has become a key step in reactor uncertainty analysis. For uncertainty analysis programs, an efficient and universal interface method can greatly improve the convenience of using uncertainty analysis. Summary of the invention

[0004] The present invention overcomes the shortcomings of the prior art, and the purpose of the present invention is to provide an efficient universal interface method suitable for reactor uncertainty analysis. The method can efficiently and conveniently realize data interaction between the reactor analysis program and the uncertainty analysis program, thereby reducing the complexity of data interaction during reactor uncertainty analysis, and at the same time has good versatility, and can realize uncertainty analysis of different programs. The present invention provides a universal interface method suitable for uncertainty analysis of reactor analysis programs.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0006] The present invention provides a general interface method suitable for uncertainty analysis of a reactor analysis program, and the present invention provides the following technical solutions:

[0007] A general interface method applicable to uncertainty analysis of a reactor analysis program, the method comprising the following steps:

[0008] Step 1: Based on a template input file, identify the parameters in the template input file that need to be modified by the interface to locate the parameters that need to be modified;

[0009] Step 2: Based on a template output file, define the corresponding aiming points and parameter identifiers for the parameters in the template output file that need to be recognized by the interface. For transient analysis, the time identifier and parameter type identifier also need to be defined;

[0010] Step 3: Based on step 1, based on the input parameter sample set and the template output file obtained in step 1, fill the input parameter sample into the corresponding position of the corresponding template input file to obtain a new input file;

[0011] Step 4: Based on step 2, the anchor point is obtained based on the template output card, and the relative position between the parameter to be extracted and the anchor point value is obtained according to the parameter identifier. For transient analysis, the relative position between time and the anchor point also needs to be extracted;

[0012] Step 5: Based on step 4, the parameter values ​​identified in step 4 are obtained based on the output file and anchor points calculated by the reactor analysis program and their relative positions to the anchor points. For transient analysis, different segments are divided according to the anchor points. The time of the segment is obtained through the relative position of the anchor points and time, and it is determined whether the time of the segment is within the range set by the user.

[0013] Preferably, step 2 specifically includes: selecting "{}" as the anchor point identifier, selecting "《》" as the output parameter identifier, selecting "￥￥" as the output parameter type symbol, and selecting a number as the parameter type symbol, where 0 represents the minimum value, 1 represents the mean value, and 2 represents the maximum value.

[0014] Preferably, the step 3 is specifically:

[0015] Step 3.1: Read a line from the input file;

[0016] Step 3.2: Determine whether there is an input parameter identifier in the line read in step 3.1. If there is no input parameter identifier, return to step 1 to read the next line. If there is an input parameter identifier, proceed to step 3.3.

[0017] Step 3.3: Identify the parameter name in the input parameter identifier, and obtain the parameter value that needs to be filled in the input parameter identifier according to the input parameter name;

[0018] Step 3.4: Based on step 3.3, the parameter value to be replaced at the position replaces the input parameter identifier and its internal parameter name as a whole, thereby modifying the parameter;

[0019] Step 3.5: In some cases, there may be multiple parameters that need to be modified in the same row, so it is necessary to determine whether the input parameter identifier still exists in the row. If the input parameter identifier still exists, return to step 3.3. If the input parameter identifier does not exist, proceed to step 3.6.

[0020] Step 3.6: Determine whether it is the last line of the input file. If it is not the last line of the input file, return to step 3.1. If it is the last line, it indicates that all parameters that need to be replaced have been replaced to form a new input file.

[0021] Preferably, the step 4 is specifically:

[0022] On the basis of step 2, based on the template output card, the anchor point is obtained, and the relative position between the parameter to be extracted and the anchor point value is obtained according to the parameter identifier. At the same time, for transient analysis, the relative position between the time and the anchor point and the type of the parameter also need to be extracted;

[0023] For steady state, the steps are as follows:

[0024] Step 4.1: Read a line from the template output file;

[0025] Step 4.2: Determine whether there is an anchor identifier in the line read in step 4.1. If there is no anchor identifier, return to step 1 to read the next line. If there is an input parameter identifier, proceed to step 4.3.

[0026] Step 4.3: Based on the anchor identifier, obtain the anchor name in the anchor identifier;

[0027] Step 4.4: Determine whether there is an output parameter identifier in the row. If there is no output parameter identifier, proceed to step 4.5. If there is an output parameter identifier, proceed to step 4.6.

[0028] Step 4.5: Entering this step means that the current line has no output parameter identifier, so read the next line and return to step 4.4;

[0029] Step 4.6: Enter this step to identify that there is an output parameter identifier in the current row, and read the relative distance between the output parameter identifier and the anchor identifier, that is, the number of words between the two identifiers;

[0030] Step 4.7: In some cases, there may be multiple output parameter identifiers in a row, so it is necessary to determine whether there are other output parameter identifiers in the row. If there are other output parameter identifiers, return to step 4.6; if not, proceed to step 4.8;

[0031] Step 4.8: Determine whether this line is the last line of the template output file. If it is not the last line, return to step 4.1 and read the next line. If so, all anchor points and their relative distances are obtained.

[0032] Preferably, the step 4 is specifically:

[0033] For transient states, the process of obtaining the anchor point name and time, the relative position of the output parameters, and the output parameter type based on the template output card is divided into the following steps:

[0034] Step S4.1: Read a line in the template output file;

[0035] Step S4.2: Determine whether there is an anchor identifier in the line read in step S4.1. If there is no anchor identifier, return to step 1 to read the next line. If there is an input parameter identifier, proceed to step S4.3.

[0036] Step S4.3: Based on the anchor identifier, obtain the anchor name in the anchor identifier;

[0037] Step S4.4: Determine whether there is a time identifier in the row. If there is a time identifier, proceed to step S4.5. If there is no output parameter identifier, proceed to step S4.6.

[0038] Step S4.5: Obtain the relative distance between the time identifier and the anchor identifier, that is, the number of words between the two identifiers, and proceed to step S4.6

[0039] Step S4.6: Determine whether there is an output parameter identifier in the row. If there is no output parameter identifier, proceed to step S4.7. If there is an output parameter identifier, proceed to step S4.8.

[0040] Step S4.7: Entering this step indicates that the current row has no output parameter identifier, so the next row is read and the process returns to step S4.6;

[0041] Step S4.8: Entering this step identifies that there is an output parameter identifier in the current row, reads the relative distance between the output parameter identifier and the anchor identifier, that is, the number of words between the two identifiers, and obtains the parameter type behind the parameter identifier;

[0042] Step S4.9: There may be multiple output parameter identifiers in a row, so it is necessary to determine whether there are other output parameter identifiers in the row. If there are other output parameter identifiers, return to step S4.8; if not, proceed to step S4.10;

[0043] Step S4.10: Determine whether this line is the last line of the template output file. If not, return to step S4.1 and read the next line. If yes, all anchor point names and their time, relative distances of output parameters and parameter types are obtained.

[0044] Preferably, for steady state, the process of obtaining the anchor point name and relative position based on the template output card to obtain output parameters is divided into the following steps:

[0045] Step 5.1: Read the newly obtained output file, traverse the output file, and slice the output file according to the anchor point name based on the anchor point name obtained in step 4;

[0046] Step 5.2: Based on step 5.1, the segments that have been divided according to the anchor points are sliced ​​again according to the spaces;

[0047] Step 5.3: Based on step 5.2 and the relative distance obtained in step 4, the desired target output parameter is obtained.

[0048] Preferably, for transient states, the process of obtaining the anchor point name, time relative position, output parameter relative position and output parameter type based on the template output card to obtain the output parameter is divided into the following steps:

[0049] Step S5.1: read the newly obtained output file, traverse the output file, and slice the output file according to the anchor point name based on the anchor point name obtained in step 4;

[0050] Step S5.2: Based on step S5.1, the segments that have been divided according to the anchor points are sliced ​​again according to the spaces;

[0051] Step S5.3: Based on step S5.2 and the time relative distance obtained in step 4, the time of the slice is obtained;

[0052] Step S5.4: Determine whether the time is within the range set by the user, if yes, proceed to step 5.5, if not, return to step S5.2;

[0053] Step S5.5: Based on step S5.2, and based on the relative distance of the output parameters obtained in step 4, the desired target output parameters are obtained;

[0054] Step S5.6: Step S5.5 is to obtain the target output parameter within a certain time range, and usually the maximum value, minimum value or mean value within the range u is obtained, so the corresponding output parameter is obtained according to the parameter identifier.

[0055] A universal interface system suitable for uncertainty analysis of a reactor analysis program, the system comprising:

[0056] A parameter identification module, which identifies the parameters in the template input file that need to be modified by the interface based on a template input file, so as to locate the parameters that need to be modified;

[0057] A transient analysis module, which is based on a template output file and defines corresponding aiming points and parameter identifiers for parameters in the template output file that need to be recognized by the interface. For transient analysis, a time identifier and a parameter type identifier also need to be defined;

[0058] An input file module, which fills the input parameter sample into the corresponding position of the corresponding template input file based on the input parameter sample set and the obtained template output file to obtain a new input file;

[0059] A time extraction module, wherein the time extraction module obtains an anchor point based on a template output card, and obtains a relative position between a parameter to be extracted and an anchor point value according to a parameter identifier. In transient analysis, the relative position between time and the anchor point also needs to be extracted;

[0162] Step 304, based on step 303, the parameter value to be replaced at the position replaces the input parameter identifier and the parameter name inside it as a whole, thereby modifying the parameter;

[0163] Step 305: In some cases, there may be multiple parameters that need to be modified in the same row, so it is necessary to determine whether there is still an input parameter identifier in the row. If there is still an input parameter identifier, return to step 303; if there is no input parameter identifier, proceed to step 306;

[0164] Step 306, determining whether it is located at the last line of the input file, if it is not the last line of the input file, returning to step 301, if it is the last line, it indicates that all parameters that need to be replaced are replaced, forming a new input file.

[0165] Step 4, based on step 2, based on the template output card, obtain the anchor point, and obtain the relative position between the parameter to be extracted and the anchor point value according to the parameter identifier. For transient analysis, it is also necessary to extract the relative position between the time and the anchor point and the type of the parameter;

[0166] For steady state, the process of obtaining anchor point names and relative positions based on the template output card is as follows: Figure 5 As shown, it is divided into the following steps:

[0167] Step 401, read a line in the template output file;

[0168] Step 402, determining whether there is an anchor identifier in the line read in step 401, if there is no anchor identifier, returning to step 1 to read the next line, if there is an input parameter identifier, proceeding to step 403;

[0169] Step 403, based on the anchor identifier, obtaining the anchor name in the anchor identifier;

[0170] Step 404, determine whether there is an output parameter identifier in the row, if not, proceed to step 405, if there is an output parameter identifier, proceed to step 406;

[0171] Step 405: Entering this step indicates that the current row has no output parameter identifier, so the next row is read and the process returns to step 404;

[0172] Step 406, entering this step to identify that there is an output parameter identifier in the current row, read the relative distance between the output parameter identifier and the anchor identifier, that is, the number of words between the two identifiers;

[0173] Step 407, in some cases, there may be multiple output parameter identifiers in a row, so it is necessary to determine whether there are other output parameter identifiers in the row. If there are other output parameter identifiers, return to step 406, if not, proceed to step 408;

[0174] Step 408, determine whether the line is the last line of the template output file, if not the last line, return to step 401, read the next line, if so, all anchor points and their relative distances are obtained.

[0179] Step 404, determine whether the row has a time identifier, if so, proceed to step 405, if not, proceed to step 406;

[0180] Step 405, obtain the relative distance between the time identifier and the anchor identifier, that is, the number of words between the two identifiers, and proceed to step 406

[0181] Step 406, determine whether there is an output parameter identifier in the row, if not, proceed to step 407, if there is an output parameter identifier, proceed to step 408;

[0182] Step 407: Entering this step indicates that the current row has no output parameter identifier, so the next row is read and the process returns to step 406;

[0183] Step 408, entering this step to identify that there is an output parameter identifier in the current row, read the relative distance between the output parameter identifier and the anchor identifier, that is, the number of words between the two identifiers, and obtain the parameter type behind the parameter identifier;

[0184] Step 409, in some cases, there may be multiple output parameter identifiers in a row, so it is necessary to determine whether there are other output parameter identifiers in the row. If there are other output parameter identifiers, return to step 408, if not, proceed to step 410;

[0185] Step 410, determine whether the line is the last line of the template output file, if not, return to step 401, read the next line, if yes, then obtain all the anchor point names and their time and the relative distance of the output parameters and the type of the parameters.

[0186] Step 5, based on step 4, based on the output file calculated by the reactor analysis program and the anchor point and the relative position with the anchor point, obtain the parameter value identified in step 4. For transient analysis, divide different segments according to the anchor points, obtain the time of the segment through the relative position of the anchor point and time, and judge whether the time of the segment is within the range set by the user.

[0187] For steady state, the process of obtaining the anchor point name and relative position based on the template output card to obtain the output parameters is as follows: Figure 7 As shown, it is divided into the following steps:

[0188] Step 501, read the newly obtained output file, traverse the output file, and slice the output file according to the anchor point name based on the anchor point name obtained in step 4;

[0189] Step 502: based on step 501, the segments that have been divided according to the anchor points are sliced ​​again according to the spaces;

[0190] Step 503, based on step 502 and the relative distance obtained in step 4, obtain the desired target output parameter.

[0193] Step 502: based on step 501, the segments that have been divided according to the anchor points are sliced ​​again according to the spaces;

[0194] Step 503, based on step 502 and the time relative distance obtained in step 4, obtain the time of the slice;

[0195] Step 504, determining whether the time is within the range set by the user, if yes, proceeding to step 505, if not yes, returning to step 502;
