[0046] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0047] As the scale of the power grid continues to expand, it is necessary to integrate the parameters of primary and secondary equipment, that is, to combine the real-time operation data of the primary equipment with the protection, control and monitoring functions of the secondary equipment. When the primary equipment performs switching operations, the grid structure changes, or the equipment position is adjusted, the parameters of the secondary equipment are adjusted accordingly.

[0048] In the prior art, the parameters of the secondary equipment are adjusted by manually maintaining the Excel ledger of the secondary equipment. However, when the ledger is maintained manually, there may be incomplete records and untimely updates, which may easily lead to protection mismatch and then offside tripping time. Therefore, the prior art has low real-time performance when processing the parameters of the secondary equipment.

[0049] In view of this, the present application provides a secondary device parameter processing method that can maintain secondary device parameters in a timely manner. The secondary device parameter processing method provided in the embodiment of the present application, its execution subject can be a secondary device parameter processing device, and the secondary device parameter processing device can be implemented by software, hardware, or a combination of software and hardware. It can be embedded in or independent of the processor in the computer device in the form of hardware, or it can be stored in the memory of the computer device in the form of software. In the following method embodiments, the execution subject is a computer device as an example for explanation, wherein the computer device can be a server, or a desktop computer or a laptop computer. The embodiment of the present application does not limit the specific type of the computer device.

[0050] In an exemplary embodiment, as shown in FIG1 , a secondary device parameter processing method is provided, including the following steps 101 to 103. Among them:

[0051] S101, obtaining a first device parameter of a first secondary device and a second device parameter of a second secondary device.

[0052] The first secondary device and the second secondary device are two adjacent secondary devices in the same feeder line, and the first secondary device is located at an upper level of the second secondary device.

[0053] Optionally, the secondary equipment can be the equipment in the power system that controls, protects, monitors and measures the operation of the primary equipment. The secondary equipment may include relays, operating switches, buttons and automatic control equipment, etc. The primary equipment can be the equipment in the power system that directly participates in the production, transmission and distribution of electric energy. The primary equipment may include generators, transformers, circuit breakers, automatic switches, etc.

[0054] In one possible implementation, when switch operations, network structure adjustments, and equipment position adjustments of primary or secondary equipment occur in the power system, the corresponding feeder lines can be acquired in real time, and then the equipment parameters of all secondary equipment in the feeder lines can be acquired.

[0055] In another possible implementation, the equipment parameters of all secondary devices in all feeder lines in the power system can be obtained according to a preset execution cycle. It can be understood that the preset execution cycle can be in units of hours, days, months or years, and the embodiments of the present application are not limited to this.

[0056] Optionally, the first device parameter may be pre-set by the operation and maintenance personnel, or may be the ideal device parameter of the first and second devices. The ideal device parameter may be determined based on the structure of the power system, which is not limited in the embodiments of the present application. The second device parameter may be pre-set by the operation and maintenance personnel, and the first device parameter and the second device parameter may be saved in a database or configuration file.

[0057] Exemplarily, if the method in the embodiment of the present application is applied to determine that the parameter verification result of the equipment parameters of the first secondary device is abnormal, then, when determining the parameter verification result of the second secondary device, the ideal equipment parameters of the first secondary device can be used as the first equipment parameters; when the parameter verification result of the equipment parameters of the first secondary device is normal, when determining the parameter verification result of the second secondary device, the ideal equipment parameters of the first secondary device can be used as the first equipment parameters, or the parameters pre-set by the operation and maintenance personnel can be used as the first equipment parameters.

[0058] Optionally, the device parameters of the secondary device can be determined by the device identification of the secondary device, and the device parameters can be displayed on the terminal interface. The operation and maintenance personnel can configure the device parameters of the secondary device through the terminal interface, including adding, editing, deleting, exporting and comparing historical device parameters.

[0059] S102: Perform parameter verification on the second device parameter according to the first device parameter and the second device parameter.

[0060] Optionally, the equipment parameters may include protection setting value, protection time limit, current transformer ratio (CurrentTransformer Ratio, CT change) and voltage transformer ratio (PotentialTransformer Ratio, PT ratio) and the like.

[0061] Optionally, in a feeder line, starting from the secondary equipment located in the station to the secondary equipment at the end of the feeder line, the equipment parameters can be gradually reduced. At the same time, if a feeder line has multiple nodes or branches (contact points), there can be multiple paths. The minimum value of the equipment parameters of the boundary circuit breaker of the current feeder line is less than the minimum value of the equipment parameters of all section switches, and the maximum value of the protection setting value and the maximum value of the protection time limit of the section switch are less than the protection setting value and the protection time limit of the circuit breaker at the end of the feeder line.

[0062] In one possible implementation, the first secondary device and the second secondary device may be input into a pre-trained verification model to perform parameter verification on the second device parameters according to an output of the verification model. The verification model may be a classification model.

[0063] In another possible implementation, numerical calculation may be performed based on the first device parameter and the second device parameter, and then the numerical calculation result may be compared with a preset threshold value to verify the parameter of the second device.

[0064] S103: If the result of the parameter verification is abnormal, an alarm is issued.

[0065] Optionally, the alarm prompt can be made through visual alarm, sound alarm, text alarm or communication alarm. The visual alarm can be made by controlling the color of the display interface of the computer device, or using an alarm signal light. The sound alarm can be made by controlling the computer device to produce an alarm sound, or a text alarm can be made by controlling an alarm window to pop up on the display interface of the computer device. The alarm information can also be sent to the operation and maintenance personnel's terminal via email, text message or push for communication alarm. At the same time, when a communication alarm is given, the operation and maintenance personnel's terminal can be controlled to simultaneously give visual alarms and sound alarms. The embodiment of the present application does not limit the method of alarm prompts.

[0066] The above secondary equipment parameter processing method obtains the first equipment parameter of the first secondary equipment and the second equipment parameter of the second secondary equipment, wherein the first secondary equipment and the second secondary equipment are two adjacent secondary equipment in the same feeder line, and the first secondary equipment is located at the upper level of the second secondary equipment; then, the second equipment parameter is parameter-checked according to the first equipment parameter and the second equipment parameter; finally, when the result of the parameter check is abnormal, an alarm is issued. In this way, when the primary equipment is adjusted, the parameters of the secondary equipment in the feeder line involved in the adjustment can be checked, that is, the equipment parameters of the secondary equipment and the equipment parameters of the upper level secondary equipment of the secondary equipment are obtained, and then the equipment parameters of the secondary equipment are checked to determine whether the equipment parameters of the current secondary equipment match when the feeder line is adjusted, and an alarm is issued when an abnormal situation occurs, so that the operation and maintenance personnel can promptly know the secondary equipment with abnormal equipment parameters, and promptly maintain the equipment parameters of the secondary equipment, which can effectively improve the real-time performance of the secondary equipment parameter maintenance, and will not miss the processing, and can also improve the accuracy of the secondary equipment parameter maintenance.

[0067] In an exemplary embodiment, as shown in FIG2 , optionally, performing parameter verification on the device parameters of the second secondary device according to the first device parameters and the second device parameters includes the following steps 201 to 202 . Among them:

[0068] S201, obtaining preset protection rules.

[0069] The preset protection rules include quick-break protection rules, overcurrent protection rules and zero-sequence overcurrent protection rules.

[0070] Optionally, the setting of preset protection rules can prevent damage to primary equipment or fire caused by excessive current. This is usually achieved by setting it on the secondary equipment, that is, when the current exceeds the set value or the current exceeds the set value and continues for a set time limit, fault isolation is performed to prevent the fault from spreading to a larger area.

[0071] Optionally, in the preset protection rules, in the feeder line, starting from the secondary equipment in the station to the secondary equipment at the end of the feeder line, the protection setting value and the protection time limit gradually decrease, and the protection setting value and protection time limit of each secondary equipment form an effective differential for coordination.

[0072] Exemplarily, the setting value of the quick-break protection (overcurrent stage I) can be 2200A, and the protection time limit can be 0.4s. The setting value of the overcurrent protection (overcurrent stage II) can be 720A, and the protection time limit can be 0.9s. The setting value of the zero-sequence overcurrent protection can be 60A, and the protection time limit can be 1s. It can be understood that when the setting value is higher, the protection time limit is shorter, and when the setting value is lower, the protection time limit is longer, which can avoid interference of current disturbance on the protection action and improve the accuracy of the protection mechanism of the secondary equipment.

[0073] Optionally, the preset thresholds in the quick-break protection rule, the overcurrent protection rule and the zero-sequence overcurrent protection rule are different.

[0074] S202: Perform parameter verification on the second device parameter according to the first device parameter, the second device parameter and a preset protection rule to determine a result of the parameter verification.

[0075] In a possible implementation, as shown in FIG3 , optionally, the first device parameter includes a first quick-break protection parameter, a first overcurrent protection parameter, and a first zero-sequence overcurrent protection parameter, and the second device parameter includes a second quick-break protection parameter, a second overcurrent protection parameter, and a second zero-sequence overcurrent protection parameter. The second device parameter is parameter-checked according to the first device parameter, the second device parameter, and a preset protection rule to determine the result of the parameter check, including the following steps 301 to 304. Wherein:

[0076] S301, determining a first verification result according to a first quick-break protection parameter, a second quick-break protection parameter and a quick-break protection rule.

[0077] Optionally, the quick-trip protection rule may include a protection setting value sub-rule and a protection time limit sub-rule, wherein the protection setting value sub-rule may be that the first quick-trip protection parameter and the second quick-trip protection parameter satisfy a preset quick-trip setting value, and the protection time limit sub-rule may be that the first quick-trip protection parameter and the second quick-trip protection parameter satisfy a preset quick-trip time limit.

[0078] Optionally, after determining the first quick-break protection parameter and the second quick-break protection parameter, the first setting value difference and the first time limit difference can be determined according to the first quick-break protection parameter and the second quick-break protection parameter, and then the first setting value difference is compared with the preset quick-break setting value, and the first time limit difference is compared with the preset quick-break time limit to obtain a first verification result.

[0079] Optionally, the first verification result may include that the second device parameter is completely matched, mismatched, or the level difference is not satisfied.

[0080] S302, determining a second verification result according to the first overcurrent protection parameter, the second overcurrent protection parameter and the overcurrent protection rule.

[0081] Optionally, similar to the method of determining the first verification result, the overcurrent protection rule may also include a protection setting value sub-rule and a protection time limit sub-rule. In the overcurrent protection rule, the protection setting value sub-rule may be that the first overcurrent protection parameter and the second overcurrent protection parameter satisfy a preset overcurrent setting value, and the protection time limit sub-rule may be that the first overcurrent protection parameter and the second overcurrent protection parameter satisfy a preset overcurrent time limit.

[0082] Optionally, after determining the first overcurrent protection parameter and the second overcurrent protection parameter, a second setting value difference and a second time limit difference can be determined according to the first overcurrent protection parameter and the second overcurrent protection parameter, and then the second setting value difference is compared with the preset overcurrent setting value, and the second time limit difference is compared with the preset overcurrent time limit to obtain a second verification result. It can be understood that the second verification result may also include a complete match, mismatch or non-satisfaction of the second device parameters.

[0083] S303, determining a third verification result according to the first zero-sequence overcurrent protection parameter, the second zero-sequence overcurrent protection parameter and the zero-sequence overcurrent protection rule.

[0084] Optionally, similar to the method of determining the first verification result, the zero-sequence overcurrent protection rule may also include a protection setting value sub-rule and a protection time limit sub-rule. In the zero-sequence overcurrent protection rule, the protection setting value sub-rule may be that the first zero-sequence overcurrent protection parameter and the second zero-sequence overcurrent protection parameter satisfy a preset zero-sequence overcurrent setting value, and the protection time limit sub-rule may be that the first zero-sequence overcurrent protection parameter and the second zero-sequence overcurrent protection parameter satisfy a preset zero-sequence overcurrent time limit.

[0085] Optionally, after determining the first zero-sequence overcurrent protection parameter and the second zero-sequence overcurrent protection parameter, a third setting value difference and a third time limit difference can be determined according to the first zero-sequence overcurrent protection parameter and the second zero-sequence overcurrent protection parameter, and then the third setting value difference is compared with the preset zero-sequence overcurrent setting value, and the third time limit difference is compared with the preset overcurrent time limit to obtain a third verification result. It can be understood that the third verification result may also include a complete match, mismatch or non-satisfaction of the second device parameters.

[0086] S304, determining a result of the parameter verification according to the first verification result, the second verification result and the third verification result.

[0087] Optionally, after determining the first verification result, the second verification result and the third verification result, the result of the parameter verification may be determined according to the three verification results.

[0088] In one possible implementation, the first verification result, the second verification result, and the third verification result may be combined to determine the result of the parameter verification.

[0089] In another possible implementation manner, the verification result in which there is a mismatch or the level difference is not satisfied among the first verification result, the second verification result, and the third verification result may be used as the result of the parameter verification.

[0090] Optionally, the result of the parameter verification may include verification rules and verification results. The embodiment of the present application does not limit the specific content of the result of the parameter verification.

[0091] Exemplarily, when the first verification result is that the second device parameters are fully matched, the second verification result is that the second device parameters are mismatched, and the third verification result is that the second device parameters are mismatched, the result of the parameter verification can be "when the verification rule is the quick-break protection rule, the second device parameters are fully matched; when the verification rule is the overcurrent protection rule, the second device parameters are mismatched; when the verification rule is the zero-sequence overcurrent protection rule, the second device parameters are mismatched", the result of the parameter verification can also be "when the verification rule is the overcurrent protection rule, the second device parameters are mismatched; when the verification rule is the zero-sequence overcurrent protection rule, the second device parameters are mismatched".

[0092] In another possible implementation, as shown in FIG4 , performing parameter verification on the second device parameter according to the first device parameter, the second device parameter and the preset protection rule to determine the result of the parameter verification may include the following steps 401 to 402. Among them:

[0093] S401, obtaining multiple ideal setting values ​​of the second secondary device.

[0094] Among them, each ideal setting value corresponds to each preset protection rule.

[0095] Optionally, the ideal setting value corresponding to the quick-break protection rule can be determined according to the following formula:

[0096] I1=K k I He / Ud%

[0097] Among them, I1 can be the ideal setting value corresponding to the quick-break protection rule; I He K is the rated current of the high-voltage side of the distribution transformer, that is, the maximum current value allowed to pass through the distribution transformer when it is running on the high-voltage side. It can be determined according to the location of the second and secondary equipment and the grid structure of the distribution network; k is the reliability coefficient, K k ≥1.3, Ud% is the short-circuit percentage of the distribution transformer. If there is no specific data, 6% can be taken.

[0098] Optionally, the ideal setting value corresponding to the overcurrent protection rule can be determined according to the following formula:

[0099] I2=K k ×K zqd ×Kfz ×∑I e

[0100] Among them, I2 can be the ideal setting value corresponding to the overcurrent protection rule; K k is the reliability coefficient. In the overcurrent protection rule, it can be taken as 1.2-1.3, K zqd is the self-starting coefficient. When considering the comprehensive load, it is generally 1.5-2.5, K fz is the branching coefficient. When there is no situation where multiple power supplies are simultaneously supplied to the same transformer, it can be taken as 1. ∑I e It is the sum of the rated current of the high-voltage side of all grid-connected distribution transformers and the rated current of the 10kV (or 20kV) load for all users supplied by the feeder line).

[0101] Optionally, the ideal setting value corresponding to the zero-sequence overcurrent protection rule can be determined according to the following formula:

[0102] I3=I0 / K P

[0103] Among them, I3 can be the ideal setting value corresponding to the zero-sequence overcurrent protection rule, I0 is the zero-sequence overcurrent protection setting value of the feeder line or the upper secondary equipment in the station, and K p For the matching coefficient, take 1.1-1.2.

[0104] S402, determining a result of parameter verification according to the second device parameter, each ideal setting value and a corresponding preset protection rule.

[0105] Optionally, when determining the result of the parameter verification, the parameter verification result may also include a first verification result, a second verification result and a third verification result.

[0106] Optionally, the first verification result is determined based on the second quick-trip protection parameter in the second device parameter and the ideal setting value I1 corresponding to the quick-trip protection rule. The quick-trip protection rule may also include an ideal setting value sub-rule. The ideal setting value sub-rule may be that the difference between the setting value in the second quick-trip protection parameter and the ideal setting value I1 satisfies the first preset difference threshold.

[0107] Optionally, when the difference satisfies a first preset difference threshold, the first verification result may be a complete match; and when the difference does not satisfy the first preset difference threshold, the first verification result may be a mismatch.
