All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The embodiment of the application discloses a method for evaluating the running state of a GIL system, which comprises the following steps: determining an evaluation threshold value of each set characteristic parameter of each functional module, wherein each functional module is obtained by carrying out module division on a GIL system in advance; when the GIL system runs, obtaining the running data of the set characteristic parameters of each functional module; comparing and calculating the evaluation threshold value of the set characteristic parameter of each functional module with the operation data to obtain the deviation value of the set characteristic parameter of each functional module; determining a deviation value of the GIL system in operation according to the deviation value of the set characteristic parameter of each functional module; and evaluating whether the running state of the GIL system is a reliable state or not according to the deviation value of the GIL system in running. In the application, the evaluation of the operation state of the GIL system is realized.
Next, a method for evaluating an operation state of a GIL system disclosed in an embodiment of the present application is described, referring to fig. 1, where the method may include:
step S11 is to determine the evaluation threshold of the setting characteristic parameter for each functional module.
In this embodiment, each of the functional modules is obtained by performing module division on the GIL system in advance.
The GIL system may be divided into modules in advance from a set angle according to requirements. Preferably, the GIL system may be divided into modules in advance from the structural aspect, and the functional modules obtained by the division may be, but are not limited to: the device comprises a straight line section unit module, a vertical shaft unit module, a 90-degree corner unit module, a small-angle corner unit module, an expansion joint module, an isolation unit module and a detachable unit module.
After the GIL system is divided into modules in advance, the evaluation threshold of the set characteristic parameter of each functional module can be determined. Wherein, setting the characteristic parameters can be understood as: and the characteristic parameters are used for reflecting whether the functional module runs reliably. The setting of the evaluation threshold of the characteristic parameter can be understood as: and when the functional module runs reliably, setting a numerical value corresponding to the characteristic parameter.
And step S12, acquiring the operation data of the set characteristic parameters of each functional module when the GIL system operates.
In this embodiment, when the GIL system operates, the acquisition device may be used to acquire the operation data of the respective set characteristic parameters of each functional module, so as to complete the acquisition of the operation data.
Step S13, comparing the evaluation threshold of the set characteristic parameter of each functional module with the operation data to obtain a deviation value of the set characteristic parameter of each functional module.
One embodiment of the comparison calculation of the evaluation threshold of the set characteristic parameter of each functional module with the operating data may be:
judging whether the operating data of the set characteristic parameters of each functional module is within the evaluation threshold range;
if yes, determining that the deviation value of the set characteristic parameter of each functional module is zero;
if not, the difference value between the operation data of the set characteristic parameters of each functional module and the evaluation threshold value thereof can be calculated to be used as a deviation numerical value.
And step S14, determining a deviation value of the GIL system in operation according to the deviation value of the set characteristic parameter of each functional module.
Because each functional module is obtained by carrying out module division on the GIL system, the overall deviation value of the GIL system during operation can be determined according to the deviation value of the set characteristic parameter of each functional module.
In the case where there is no hierarchical relationship between the set feature parameters of the function modules, the sum of the deviation values of the set feature parameters of each function module may be used as the deviation value of the GIL system during operation.
Currently, when there is a hierarchical relationship between the set feature parameters of the function modules, the deviation value of the GIL system during operation needs to be determined according to the deviation value and the hierarchical relationship of the set feature parameters of each function module.
And step S15, evaluating whether the operation state of the GIL system is a reliable state or not according to the deviation value of the GIL system in operation.
The deviation degree of the whole system of the GIL deviating from the reliable operation can be reflected on the basis of the deviation value of the GIL system in the operation, and preferably, whether the operation state of the GIL system is a reliable state or not is evaluated according to the deviation value of the GIL system in the operation.
In this embodiment, the correspondence between the deviation value of the GIL system during operation and the operation state may be preset. Accordingly, evaluating whether the operation state of the GIL system is a reliable state according to the deviation value of the GIL system during operation may include: searching the running state corresponding to the deviation value of the GIL system in running in the corresponding relation of the deviation value and the running state; if the searched running state is the reliable state, the running state of the GIL system can be determined to be the reliable state; if the searched operation state is the unreliable state, the operation state of the GIL system can be determined to be the unreliable state.
In the application, determining an evaluation threshold of each set characteristic parameter of each function module as a corresponding reference value of each set characteristic parameter when the GIL system is in reliable operation, acquiring operation data of each set characteristic parameter of each function module when the GIL system is in operation, comparing the evaluation threshold of each set characteristic parameter of each function module with the operation data to obtain a deviation value of each set characteristic parameter of each function module, reflecting the degree of deviation of the set characteristic parameter from the reference value when the GIL system is in operation through the deviation value, and on the basis, determining the deviation value of the GIL system when the GIL system is in operation according to the deviation value of each set characteristic parameter of each function module, reflecting the degree of deviation of the whole GIL system from reliable operation through the deviation value of the GIL system when the GIL system is in operation, and further evaluating whether the running state of the GIL system is a reliable state or not according to the integral deviation value of the GIL system, and finishing the evaluation of the running state of the GIL system.
In another embodiment of the present application, the above-mentioned determining the evaluation threshold of the set characteristic parameter of each functional module is described with reference to fig. 2, and may include:
and step S21, acquiring standard values corresponding to the set characteristic parameters of each functional module in each stage of the whole life cycle.
The full life cycle can be understood as: the GIL system is the time period from design production to retirement. Specifically, the full life cycle may include: design, production, testing, installation and operation stages.
Of course, the full life cycle may also be set according to actual needs, for example, the full life cycle may be set as: including cycles of production, test and run phases.
The standard values are to be understood as: the values required for reliable implementation of the GIL system.
And step S22, determining the evaluation threshold value of each set characteristic parameter according to the standard value corresponding to each stage of each set characteristic parameter in the whole life cycle.
In this embodiment, an optimal standard value may be selected from the standard values corresponding to the set characteristic parameters at each stage in the full life cycle, and the optimal standard value may be respectively used as the evaluation threshold of each set characteristic parameter.
Of course, according to needs, a standard value range may be determined according to the standard value corresponding to each stage of the set characteristic parameter in the full life cycle, and the determined standard value range may be used as the evaluation threshold of each set characteristic parameter.
The reliability of the evaluation threshold of the set characteristic parameter can be improved by using the determined standard value range as the evaluation threshold of the set characteristic parameter.
In another embodiment of the present application, the determining the deviation value of the GIL system during operation according to the deviation values of the set characteristic parameters of each functional module is described with reference to fig. 3, which may include:
step S31, calculating the deviation value of the setting feature parameter of each level of each function module step by step according to the hierarchical relationship pre-divided for the setting feature parameter until the deviation value of the setting feature parameter of the highest level of each function module is calculated.
In this embodiment, the set feature parameters may be classified into levels in advance, and the level relationship of the set feature parameters may be determined. Preferably, the hierarchical relationship of the setting characteristic parameters can be seen in fig. 4.
The preset characteristic parameters are classified in a hierarchy mode in advance, deviation values of the preset characteristic parameters can be calculated in a hierarchical mode, and the calculation complexity is reduced. And the deviation numerical values of the set characteristic parameters of all the levels are calculated step by step according to the level relation, so that the missing calculation can be avoided, and the reliability of the calculation is improved.
In this embodiment, the step of calculating the deviation value of the setting characteristic parameter of each level of each functional module may include:
and adding the deviation values of the setting characteristic parameters of the same level of each functional module step by step, wherein the addition result is used as the deviation value of the setting characteristic parameter of the previous level.
Of course, the step-by-step calculation of the deviation value of the setting characteristic parameter of each level of each function module may also include:
and multiplying the deviation numerical values of the set characteristic parameters of the function modules belonging to the same level by the corresponding weights step by step, adding the multiplication results, and taking the addition result as the deviation numerical value of the set characteristic parameter of the previous level.
Preferably, the fuzzy theory algorithm may be used to multiply the deviation value of the setting characteristic parameter belonging to the same level of each function module by the corresponding weight step by step, and add the multiplication results, and the added result is used as the deviation value of the setting characteristic parameter of the previous level.
The deviation values of the set characteristic parameters of the same level of each function module are multiplied by the corresponding weights step by step, the multiplication results are added, and the added result is used as the deviation value of the set characteristic parameter of the previous level, so that the reliability of the deviation value of the set characteristic parameter can be improved.
Now, the process of multiplying the deviation values of the setting characteristic parameters belonging to the same level of each of the function modules by the corresponding weights, adding the multiplication results, and using the added result as the deviation value of the setting characteristic parameter of the previous level is described by way of example, for example, referring to the hierarchical relationship shown in fig. 4, the deviation value of the material can be calculated according to the deviation values of aluminum and silver, and the calculation process can be referred to table 1.
TABLE 1
Referring also to the hierarchical relationship shown in fig. 4, deviation values of the size, resistance, plating and mounting parameters from the material belonging to the same hierarchy are calculated, respectively, and the calculation results can be seen in table 2.
TABLE 2
| Material | Size of | Resistance (RC) | Coating layer | Mounting of | ||
| Deviation value | 0.01 | 0 | 0 | 0.01 | 0 |
Referring also to the hierarchical relationship shown in fig. 4, the weights of the material, the size, the resistance, the plating layer, and the mounting parameter belonging to the same hierarchy are determined, respectively, and the weights are multiplied by the corresponding deviation values, and the multiplication results are added to obtain the deviation values of the characteristic parameter (i.e., the conductive rod) of the previous hierarchy, and the calculation results are shown in table 3.
TABLE 3
Further, the sum of the deviation values of the characteristic parameters belonging to the same hierarchy as the conductive rod is calculated, and as the deviation value of the conductor, the calculation process of the deviation value of the conductor can be referred to table 4.
TABLE 4
Referring to the hierarchical relationship shown in fig. 4, the deviation value of the corresponding functional module is determined according to the deviation value of the characteristic parameter belonging to the same hierarchy as the conductor, and the deviation value of the corresponding functional module (e.g., straight line segment unit) can be referred to in table 5.
TABLE 5
And step S32, multiplying the deviation value of the set feature parameter at the highest level of the function module by the relative importance matrix corresponding to the set feature parameter at the highest level of the function module, and selecting the maximum value from the multiplication result as the deviation value of the function module.
The relative importance matrix corresponding to the set characteristic parameter of the highest level of the functional module can be understood as follows: the function module comprises an m x m matrix, wherein the value of an element in the m x m matrix is the value of the importance degree of a certain set characteristic parameter of the highest level of the function module relative to a certain set characteristic parameter. For example, the m matrix can be seen in table 6.
TABLE 6
| Conductor | Sealing ring | Insulating member | Shielding case | Gas (es) | Shell body | |
| Conductor | 1 | 3 | 5 | 9 | 8 | 7 |
| Sealing ring | 1/3 | 1 | 3 | 7 | 6 | 5 |
| Insulating member | 1/5 | 1/3 | 1 | 5 | 4 | 3 |
| Shielding case | 1/9 | 1/7 | 1/5 | 1 | 1/2 | 1/3 |
| Gas (es) | 1/8 | 1/6 | 1/4 | 2 | 1 | 1/2 |
| Shell body | 1/7 | 1/5 | 1/3 | 3 | 2 | 1 |
The deviation numerical value of the set characteristic parameter of the highest level of the functional module is multiplied by the relative importance matrix corresponding to the set characteristic parameter of the highest level of the functional module, and the maximum value is selected from the multiplication result to be used as the deviation numerical value of the functional module, so that the reliability of the deviation numerical value of the functional module can be improved.
And step S33, multiplying the deviation value of each function module by the weight of each function module, and adding the multiplication results, wherein the addition result is used as the deviation value of the GIL system in operation.
Because the importance degrees of different functional modules in the operation of the GIL system are possibly different, the weights of the functional modules can be set, the deviation values of the functional modules are multiplied by the weights of the functional modules, the multiplication results are added, the added result is used as the deviation value of the GIL system in the operation, and the reliability of the calculated deviation value of the GIL system in the operation is improved.
