[0051] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0052] This application provides an evaluation method, apparatus, electronic device, and storage medium.
[0053] Specifically, the evaluation device can be integrated into an electronic device, such as a terminal or server. The terminal can be a mobile phone, tablet, smart Bluetooth device, laptop, or personal computer (PC); the server can be a single server or a server cluster consisting of multiple servers.
[0054] In some embodiments, the evaluation device may also be integrated into multiple electronic devices, such as multiple servers, with multiple servers implementing the evaluation method of this application.
[0055] In some embodiments, the server may also be implemented as a terminal.
[0056] For example, refer to Figure 1a The electronic device can respond to component failure by acquiring operating parameters and fault indication information associated with the component; using the operating parameters, it calculates a first deduction value, which represents the degree of component failure; using the fault indication information, it calculates a second deduction value, which also represents the degree of component failure; and based on the first and second deduction values, it performs a fault assessment on the component to obtain an assessment result.
[0057] In this application, when assessing the failure of a component, the operating parameters associated with the component and the fault indication information can be considered simultaneously, so as to achieve a comprehensive assessment of the degree of failure of the component. This allows users to replace the components in the equipment in a timely manner based on the assessment results, thereby reducing the impact of component damage on the normal operation of the equipment.
[0058] The following sections provide detailed descriptions of each example. It should be noted that the sequence numbers of the following embodiments are not intended to limit the preferred order of the embodiments.
[0059] In this embodiment, an evaluation method is provided. The method is applied to a device, which includes components such as... Figure 1b As shown, the specific process of this evaluation method can be as follows:
[0060] 110. In response to component failure, obtain the operating parameters and fault prompt information associated with the component.
[0061] Among them, the operating parameters are the parameters associated with the component when it is running in the equipment, such as the parameters in the equipment that are affected when the component fails.
[0062] For example, when the equipment is a synchronous condenser and the component is a rotor, the operating parameters associated with the component can be the absolute value of the relative deviation of the excitation current, the maximum value of the shaft vibration frequency at the turning end, the maximum value of the shaft vibration frequency change rate at the turning end, the maximum value of the excitation end cover vibration frequency, the maximum value of the excitation end cover vibration frequency change rate, the maximum value of the percentage δ of the magnetic flux difference, the maximum value of the turning end bearing temperature, the maximum value of the excitation end bearing temperature, and the peak-to-peak value of the shaft voltage, etc.
[0063] Among them, fault indication information is the information issued by the equipment when a component fails, such as information related to the fault level of the component, such as minor fault level, serious fault level, and emergency fault level.
[0064] 120. Using the operating parameters, calculate the first deduction value, which represents the degree of failure of the component.
[0065] The first deduction value is the deduction value obtained through operating parameters when evaluating component failure, and this deduction value characterizes the degree of component failure.
[0066] In some embodiments, in order to calculate the deduction value when a component is in a faulty state using operating parameters, the operating parameters are used to calculate a first deduction value, including:
[0067] Determine the current degree of degradation corresponding to the operating parameters. The current degree of degradation represents the extent to which the operating parameters deviate from the normal value at the current time.
[0068] Based on the current degree of degradation, determine the membership degree of the operating parameters to each fault level;
[0069] The first deduction value is determined based on all membership degrees corresponding to each running parameter.
[0070] The current degradation degree is the degree to which the operating parameter deviates from the normal value at the current time. For example, the degree to which the operating parameter deviates from the normal value can determine the corresponding degradation degree of the operating parameter.
[0071] The normal values are the operating parameters associated with the component when it is running normally. For example, the operating parameters associated with the component when it is running without any damage.
[0072] Among them, the fault level is used to indicate the level of a component failure. For example, the fault level can include the normal level, the minor fault level, the serious fault level, the emergency fault level, and so on.
[0073] The membership degree characterizes the degree to which an operating parameter belongs to a fault level, and this membership degree is calculated using the current degree of degradation. For example, fault levels include normal, minor, severe, and emergency fault levels. Therefore, based on the current degree of degradation corresponding to the operating parameter, we can obtain the membership degree of the operating parameter belonging to the normal level, the minor fault level, the severe fault level, and the emergency fault level, and so on.
[0074] In some embodiments, considering that the degradation degree corresponding to the operating parameters can be calculated, determining the current degradation degree corresponding to the operating parameters includes:
[0075] Obtain the degradation function associated with the running parameters;
[0076] Based on the degradation function and operating parameters, determine the current degradation level corresponding to the operating parameters.
[0077] The degradation degree function is a function that calculates the degradation degree using the running parameters.
[0078] In some embodiments, reference Figure 1c Each operating parameter is associated with a degradation function that includes two parameter values, a and b. The degradation degree of parameter a calculated by the degradation function is 0, and the degradation degree of parameter b calculated by the degradation function is 1. The degradation degree of parameters between parameters a and b increases linearly. The operating parameter can be equal to parameter a or parameter b, or it can be equal to other parameter values.
[0079] From Table 1, we can see that the values of a and b can be:
[0080] Table 1
[0081]
[0082]
[0083] For example, if the operating parameter is the absolute value of the relative deviation of the excitation current and equal to x1, and the degradation function associated with the absolute value of the relative deviation of the excitation current is I(x1), then the current degradation degree corresponding to x1 is I1.
[0084] The operating parameter is the maximum value of the shaft vibration frequency at the turning gear end, which is equal to x2. The degradation function associated with the maximum value of the shaft vibration frequency at the turning gear end is I(x2). Then the current degradation degree corresponding to x2 is I2.
[0085] The operating parameter is the maximum value of the change rate of the shaft vibration frequency at the turning end, which is equal to x3. The degradation function associated with the maximum value of the change rate of the shaft vibration frequency at the turning end is I(x3). Then the current degradation degree corresponding to x3 is I3.
[0086] The operating parameter is the maximum value of the excitation end cover vibration frequency and equal to x4. The degradation function associated with the maximum value of the excitation end cover vibration frequency is I(x4). Then the current degradation degree corresponding to x4 is I4.
[0087] The operating parameter is the maximum value of the excitation end cover vibration frequency change rate, which is equal to x5. The degradation function associated with the maximum value of the excitation end cover vibration frequency change rate is I(x5). Then the current degradation degree corresponding to x5 is I5.
[0088] The operating parameter is the maximum value of the flux difference percentage δ, which is equal to x6. The degradation function associated with the maximum value of the flux difference percentage δ is I(x6). Then the current degradation degree corresponding to x6 is I6.
[0089] The operating parameter is the maximum temperature of the turning gear end bearing, which is equal to x7. The degradation function associated with the maximum temperature of the turning gear end bearing is I(x7). Then the current degradation degree corresponding to x7 is I7.
[0090] The operating parameter is the maximum temperature of the excitation end bearing, which is equal to x8. The degradation function associated with the maximum temperature of the excitation end bearing is I(x8). Then the current degradation degree corresponding to x8 is I8.
[0091] The operating parameter is the peak-to-peak value of the shaft voltage, which is equal to x9. The degradation function associated with the peak-to-peak value of the shaft voltage is I(x9). Then the current degradation degree corresponding to x9 is I9.
[0092] In some embodiments, in order to consider that the degree of degradation corresponding to the operating parameter can be associated with the fault level of the component, the membership degree of the operating parameter to each fault level is determined based on the current degree of degradation, including:
[0093] Obtain the membership functions corresponding to all fault levels;
[0094] Based on the current degree of degradation and all membership functions, determine the membership degree of the operating parameters to each fault level.
[0095] The membership function is used to associate operating parameters with fault levels based on the degree of degradation.
[0096] Fault levels are categorized into normal, minor, serious, and emergency levels. For example, refer to... Figure 1d , which is the membership function corresponding to the above fault levels.
[0097] The membership function corresponding to the normal level is r1:
[0098] r1={0.5-0.5*sin[π(I-0.15) / 0.3], 1∈[0,0.3]; 0, I∈(0.3, 1]}.
[0099] The membership function corresponding to the severity of a minor fault is r²:
[0100]
[0101] The membership function corresponding to the severity level of the fault is r3:
[0102]
[0103] The membership function corresponding to the severity level of the fault is r4:
[0104] r4={0, I∈[0,0.7], 0.5+0.5*sin[π(I-0.85) / 0.3], I∈(0.7, 1]}.
[0105] Specifically, substituting the current degradation degree I1 into r1 yields w11; substituting the current degradation degree I1 into r2 yields w12; substituting the current degradation degree I1 into r3 yields w13; and substituting the current degradation degree I1 into r4 yields w14. The membership vector W1(w11,w12,w13,w14) for x1 is constructed using w11, w12, w13, and w14. The remaining current degradation degrees I2 to I9 are calculated using the same method to obtain the membership vectors W2 for x2, W3 for x3, W4 for x4, W5 for x5, W6 for x6, W7 for x7, W8 for x8, and W9 for x9. This forms the membership matrix W(W1; W2; W3; W4; W5; W6; W7; W8; W9) corresponding to all operating parameters. This membership matrix has 9 rows and 4 columns.
[0106] In some embodiments, considering that there is more than one operating parameter associated with a component, when evaluating the component's failure, in order to merge the membership degrees corresponding to all operating parameters to generate a parameter that facilitates the evaluation of the component's failure, a first deduction value is determined based on all membership degrees corresponding to each operating parameter, including:
[0107] Obtain the first weight corresponding to the operating parameters, and the second weight corresponding to each fault level;
[0108] Multiply and sum the membership degrees corresponding to the first weight, all second weights, and the running parameters to obtain the target value corresponding to the running parameters.
[0109] The first deduction value is determined based on the target values corresponding to all operating parameters.
[0110] The first weight is the proportion of the pre-set operating parameters in the component failure assessment.
[0111] The method for obtaining the first weight corresponding to the running parameters:
[0112] Table 2
[0113]
[0114]
[0115] For example, as shown in Table 2, the weighting coefficients for the absolute value of the relative deviation of the excitation current, the maximum value of the turning gear end shaft vibration frequency, the maximum value of the turning gear end shaft vibration frequency change rate, the maximum value of the excitation end cover vibration frequency, the maximum value of the excitation end cover vibration frequency change rate, the maximum value of the percentage of magnetic flux difference δ, the maximum value of the turning gear end bearing temperature, and the maximum value of the excitation end bearing temperature are all 1. The weighting coefficient for the peak-to-peak value of the shaft voltage is 0.4. The sum of the weighting coefficients for all operating parameters is 8.4. Dividing the weighting coefficient for each operating parameter by the sum of the weighting coefficients yields the first weight for each operating parameter. Specifically, the first weight for all operating parameters can be M(1, 1, 1, 1, 1, 1, 1, 1, 0.4) / 8.4. For ease of calculation, (1, 1, 1, 1, 1, 1, 1, 1, 0.4) and 8.4 are common denominators to obtain M(5, 5, 5, 5, 5, 5, 5, 5, 2) / 42.
[0116] The second weight is the weight associated with the fault level.
[0117] For example, the weight corresponding to the fault level of normal is 100, the weight corresponding to the fault level of minor fault is 70, the weight corresponding to the fault level of serious fault is 30, and the weight corresponding to the fault level of emergency fault is 0. Then, the second weight vector corresponding to all fault levels is formed: Y(100, 70, 30, 0).
[0118] The first weight, all second weights, and the membership degrees corresponding to the running parameters are multiplied and summed to obtain the target value corresponding to the running parameters; and based on the target values corresponding to all running parameters, the calculation method for the first deduction value is determined as follows: First deduction value S0 = 100 - sum[(M*W)*Y].
[0119] In some embodiments, to assign weights to fault levels, the weights corresponding to fault levels can be determined using a membership function corresponding to the fault level. Before the second weight corresponding to each fault level, the method further includes:
[0120] The target degradation degree is determined based on the membership function corresponding to the fault level and the membership degree equal to 1.
[0121] The second weight corresponding to the fault level is determined based on the target degradation degree corresponding to the membership function.
[0122] Among them, the target degradation degree is the degradation degree corresponding to the membership degree with a membership degree of 1 in the membership function.
[0123] For example, a membership degree of 1 corresponds to a target degradation degree of 0 in membership function r1, a membership degree of 1 corresponds to a target degradation degree of 0.3 in membership function r2, a membership degree of 1 corresponds to a target degradation degree of 0.7 in membership function r3, and a membership degree of 1 corresponds to a target degradation degree of 1 in membership function r4.
[0124] That is, the target degradation degree belonging to the fault level of normal is 0, the target degradation degree belonging to the fault level of minor fault is 0.3, the target degradation degree belonging to the fault level of severe fault is 0.7, and the target degradation degree belonging to the fault level of emergency fault is 1. Thus, in order to assign weight to the fault level, the percentage of 0, 0.3, 0.7 and 1 in all target degradation degrees can be calculated respectively. The percentage corresponding to the target degradation degree of 0 is 0, the percentage corresponding to the target degradation degree of 0.3 is 30, the percentage corresponding to the target degradation degree of 0.7 is 70, and the percentage corresponding to the target degradation degree of 1 is 100.
[0125] Considering that weights are assigned to fault levels, the fault levels are assigned according to their severity, with larger values assigned to lower fault levels and larger values assigned to severe fault levels. That is, a fault level of 100% corresponds to a normal level, a fault level of 70% corresponds to a minor fault level, a fault level of 30% corresponds to a severe fault level, and a fault level of 0% corresponds to an emergency fault level. This forms the second weight vector for all fault levels: Y(100, 70, 30, 0).
[0126] 130. Using fault indication information, calculate the second deduction value, which represents the degree of fault of the component.
[0127] The second deduction value is the deduction value obtained through fault prompt information when assessing component failure, and this deduction value represents the degree of component failure.
[0128] In some embodiments, when assessing the fault level of a component, in order to incorporate factors affecting the component fault assessment, the warning information issued by the equipment when the component malfunctions is considered in the fault assessment. The fault warning information includes multiple fault levels and the number of faults corresponding to each fault level. The multiple fault levels include a first level and a second level, where the second level is lower than the first level. Using the fault warning information, a second deduction value is calculated, including:
[0129] Based on the number of faults corresponding to the first level and the number of faults corresponding to the second level, determine the median value corresponding to the first level;
[0130] If the median value corresponding to the highest fault level meets the preset conditions, the method for determining the second deduction value based on the median values corresponding to all fault levels is as follows:
[0131] If the intermediate value corresponding to the highest fault level meets the preset conditions, obtain the mapping relationship between the preset intermediate value and the preset deduction function;
[0132] The target deduction function is determined based on the mapping relationship between the preset intermediate value and the preset deduction function, as well as the intermediate value corresponding to the highest level of fault.
[0133] The second deduction value is determined based on the target deduction function and the intermediate value corresponding to the fault levels other than the highest level of fault.
[0134] If the intermediate value corresponding to the highest fault level does not meet the preset conditions, the preset deduction value will be used as the second deduction value.
[0135] The number of faults refers to the number of components that have the same fault.
[0136] For example, when a component malfunctions, the equipment issues a minor fault warning. The equipment will then count these minor fault warnings to determine the number of minor faults that have occurred in the component.
[0137] The first level is higher than the second level. For example, the first level can be a normal level, a minor fault level, a serious fault level, or an emergency fault level.
[0138] For example, when the first level is the level of minor faults and the second level is the level of normal, there is no corresponding number of faults for the level of normal. In this case, the formula for calculating the median value corresponding to the level of minor faults is a′=mod(a,5), where a′ is the median value corresponding to the level of minor faults and a is the number of faults corresponding to the level of minor faults.
[0139] For example, when the first level is the level of a serious fault, the second level is the level of a normal fault and the level of a minor fault. The normal level has no corresponding number of faults, and the number of faults corresponding to the minor fault is 'a'. In this case, the formula for calculating the intermediate value corresponding to the serious fault is b′=mod(b+int(a / 5),3), where b′ is the intermediate value corresponding to the level of a minor fault, and b is the number of faults corresponding to the level of a serious fault.
[0140] For example, when the first level is the emergency fault level, the second level is the normal level, the minor fault level, and the serious fault level. Among them, the normal level has no corresponding number of faults, the number of minor faults is 'a', and the number of minor faults is 'b'. In this case, the formula for calculating the intermediate value corresponding to the emergency fault level is c′=c+int(b+int(a / 5)) / 3, where c′ is the intermediate value corresponding to the emergency fault level, and c is the number of faults corresponding to the emergency fault level.
[0141] The intermediate value corresponding to the highest fault level can be calculated by c′=c+int(b+int(a / 5)) / 3.
[0142] The preset deduction function is used to calculate the deduction value obtained from the information of component failure issued by the device through intermediate value calculation.
[0143] The preset intermediate value is a pre-set intermediate value associated with the preset deduction function.
[0144] The mapping relationship between the preset intermediate value and the preset deduction function is used to associate the preset intermediate value with the preset deduction function.
[0145] The target deduction function is a preset deduction function that maps to the median value corresponding to the highest level of fault.
[0146] The method for determining the second deduction value, based on the target deduction function and the intermediate values corresponding to fault levels other than the highest level, is as follows:
[0147] If c′=1, the corresponding target deduction function is F=85+2b′+a′, where a minor fault deducts 1 point and a serious obstacle deducts 2 points.
[0148] If c′=0 and b′≠0, the corresponding target deduction function is F=50+4b′+2a′, where a minor fault deducts 2 points and a serious fault deducts 4 points.
[0149] If c′=0, b′=0 and a′≠0, the corresponding target deduction function is F=15+4a′, where a minor fault in this target deduction function deducts 4 points.
[0150] The deduction for component failures in the above target deduction function can be determined based on the actual situation.
[0151] If the intermediate value corresponding to the highest fault level does not meet the preset conditions, the method of using the preset deduction value as the second deduction value can be: when c′≥2, the second deduction value F is equal to the preset deduction value. The preset deduction value can be 100, or it can be set according to the actual situation.
[0152] 140. Based on the first and second deduction values, conduct a fault assessment of the component and obtain the assessment results.
[0153] The assessment result is the fault level corresponding to the component after fault assessment. For example, the assessment result can be normal, minor fault, serious fault, emergency fault, and so on.
[0154] The method for assessing component failure based on the first and second deduction values:
[0155] The score range corresponding to the fault level of the component is as follows:
[0156] Normal component rating: [85, 100], Minor component failure rating: [50, 85], Severe component failure rating: [15, 50], Emergency component failure rating: [0, 15].
[0157] The formula for assessing component failure is S = 100 - S0 - F, where S0 is the first deduction value and F is the second deduction value.
[0158] For example: Based on the score S obtained by subtracting the first and second deductions from the full score of 100, compare the intervals in which S falls. When S is in the interval [85, 100], the component is at a normal level; when S is in the interval [50, 85), the component is at a minor fault level; when S is in the interval [15, 50), the component is at a serious fault level; when S is in the interval [0, 15), the component is at a serious fault level.
[0159] In some embodiments, the above evaluation method may be loaded onto a computer controlling the device, or onto a separate device that can evaluate the device, etc.
[0160] As can be seen from the above, in response to a component failure, the embodiments of this application can obtain the operating parameters and fault prompt information associated with the component; use the operating parameters to calculate a first deduction value, which represents the degree of component failure; use the fault prompt information to calculate a second deduction value, which represents the degree of component failure; and perform a fault assessment on the component based on the first and second deduction values to obtain the assessment result.
[0161] Therefore, this solution can use a first deduction value and a second deduction value, where operating parameters and fault alert information can map the degree of component failure. The fault alert information can be a prompt indicating that the component has a minor failure, a serious failure, or an emergency failure when it is working in the equipment. This allows the operating parameters associated with the component and the fault alert information to be considered simultaneously when assessing the component's failure, so as to achieve a comprehensive assessment of the degree of component failure. This makes it easier for users to replace components in the equipment in a timely manner based on the assessment results, thereby reducing the impact of component damage on the normal operation of the equipment.
[0162] To better implement the above methods, this application also provides an evaluation device, which can be integrated into an electronic device, such as a terminal or server. The terminal can be a mobile phone, tablet computer, smart Bluetooth device, laptop computer, or personal computer; the server can be a single server or a server cluster composed of multiple servers.

[0184] The target degradation degree is determined based on the membership function corresponding to the fault level and the membership degree equal to 1.
[0185] The second weight corresponding to the fault level is determined based on the target degradation degree corresponding to the membership function.
[0186] (III) Second Calculation Unit 230.
