Description

Power distribution automation terminal protection setting value batch checking method and system TECHNICAL FIELD

[0001] The present application relates to the technical field of power distribution automation terminal protection setting value batch checking, and particularly relates to a power distribution automation terminal protection setting value batch checking method and system. BACKGROUND

[0002] With the continuous development of the power system, distribution network automation plays an increasingly important role in power grid operation. As one of the important means to ensure the safe and stable operation of the power grid, setting value comparison in distribution network automation has important significance for improving the reliability, security and economy of the power grid. However, with the gradual increase of distribution automation coverage, there are problems of "terminal is too much" and "terminal geographical distribution is wide". Due to historical problems, terminal range limitations, incorrect setting value, manual execution differences and errors, etc., the terminal setting value is executed incorrectly, which leads to protection failure.

[0003] The existing power distribution automation terminal protection setting value batch checking method often has problems of low comparison efficiency and inaccurate comparison results. On the one hand, due to the large number of terminal devices in the distribution network and the variety of setting value types, the traditional comparison method often needs to compare each setting value one by one, which leads to a tedious and time-consuming comparison process. On the other hand, the existing comparison method usually only focuses on part of the information in the setting value, and ignores the analysis and processing of other key information, which may lead to inaccurate comparison results.

[0016] Fourthly, the present invention provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the steps of the method described above.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention proposes a method and system for batch verification of protection settings of distribution automation terminals. A first setpoint list is preset, and a first recall instruction is sent to a first distribution network operation control system according to a preset first batch logic. The first recall instruction is a setpoint recall instruction corresponding to the first setpoint list, which includes operating setpoints. When the first distribution network operation control system receives the first recall instruction, it sends back the field terminal setpoints corresponding to the first recall instruction. The first setpoint list is compared with the field terminal setpoints to determine abnormal and non-abnormal states, thus completing the batch verification of protection settings of distribution automation terminals.

[0018] Firstly, by pre-setting the first batch logic, flexible processing of value setting orders with different priorities can be achieved. Based on the different priorities, the system can intelligently adjust the timing of opening the communication link to ensure that critical and urgent value setting orders are processed first, thereby improving the response speed and operational efficiency of the entire distribution network automation system.

[0019] Secondly, this invention prioritizes value setting orders by comprehensively considering multiple factors such as regional criticality level, terminal risk level, power grid operating status, historical call success rate, and terminal response time. This prioritization method is more scientific and comprehensive, and can more accurately reflect the importance and urgency of value setting orders, providing strong support for subsequent batch value setting comparisons.

[0020] Furthermore, this invention incorporates a robust communication link switching and fault diagnosis mechanism. When the primary communication link fails or fails to receive settings from the field terminal, the system automatically switches to the backup communication link and attempts to resend the recall command. If the settings still cannot be received, the system performs remote status diagnosis of the field terminal and takes appropriate measures based on the diagnosis results. This design ensures the stability and reliability of the system in complex environments.

[0021] Finally, by extracting and comparing information from field terminal settings with those in operation, this invention can accurately identify mismatched setting sheets and generate detailed comparison reports. This helps maintenance personnel quickly locate problems and take targeted measures for repair and optimization.

[0022] In summary, the batch verification method and system for protection settings of distribution automation terminals of the present invention are characterized by intelligence, high efficiency, stability and precision, which can significantly improve the operating efficiency and reliability of distribution network automation systems and provide strong protection for the safe and stable operation of power systems.

[0023] To more clearly illustrate the technical solutions of the embodiments of the present invention, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. Wherein: Figure 1 is a flowchart of a method and system for batch verification of protection settings of distribution automation terminals provided by an embodiment of the present invention; Figure 2 is an internal structural diagram of a computer device for a method and system for batch verification of protection settings of distribution automation terminals provided by an embodiment of the present invention. Detailed Implementation

[0024] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0025] Example 1 Referring to Figures 1-2, this is the first embodiment of the present invention. This embodiment provides a method and system for batch verification of protection settings of distribution automation terminals, including a method for batch verification of protection settings of distribution automation terminals and a system for batch verification of protection settings of distribution automation terminals. The method for batch verification of protection settings of distribution automation terminals includes: Before describing the embodiments of this application in detail, some related concepts will be explained for clarity.

[0026] Setting sheets: In power system automation management, setting sheets refer to a set of pre-set control parameters to ensure the correct operation of equipment (such as relay protection devices and automatic control devices). These parameters include, but are not limited to, the equipment's IP address, ID identifier, setting zone number, group number, point number, and specific functional settings (such as protection action current value, delay time, etc.). Setting sheets are the basic configuration files that ensure power equipment responds to grid conditions according to predetermined strategies.

[0027] Field terminal settings: Field terminal settings refer to the actual settings currently stored and executed by terminal equipment (such as smart terminals, remote terminal units, etc.) installed at the power grid site. These settings directly control the operating behavior of the field equipment and reflect the real-time operating status of the system. When a recall command is sent from the control center to the field, the terminal will send back these actual settings for verification against the setting sheet at the center.

[0028] Operating settings: Operating settings refer to the settings currently in operation in the power grid. They should be consistent with the field terminal settings to ensure the stability and security of the power grid operation. Operating settings typically refer to the settings that have been deployed and are in effect; they are important parameters that need to be continuously tracked and verified in power system maintenance and monitoring.

[0029] Communication link: In a power automation system, the communication link refers to the connection channel between the control center and field terminals used for exchanging data and commands. It includes various forms such as wired (e.g., fiber optic, cable) and wireless (e.g., GGPRS, LTE, satellite communication). The quality of the communication link directly affects the speed and accuracy of command transmission, as well as the timeliness and completeness of data feedback. In the above process, from sending recall commands to receiving feedback from field terminals, and then to possible fault switching and backup link activation, all rely on a stable and reliable communication link.

[0030] In related technologies, the setting management of distribution network automation systems often faces challenges such as large data volumes, unstable communication links, and cumbersome setting comparisons. Traditional setting comparison methods are usually based on individual setting sheets, lacking batch processing and intelligent optimization capabilities. This leads to inefficiency and a high risk of errors when processing a large number of setting sheets. Furthermore, unstable communication links can also cause setting retrieval failures or data loss, further increasing the difficulty of setting management.

[0031] This application provides a method that can effectively solve the problems mentioned above. The following will describe in detail how to implement the batch verification method for protection settings of distribution automation terminals using multiple embodiments. Figure 1 shows a flowchart of a method and system for batch verification of protection settings of distribution automation terminals, including: S101, presetting a first setpoint list and sending a first recall instruction to a first distribution network operation control system according to a preset first batch logic. The first recall instruction is a setpoint recall instruction corresponding to the first setpoint list, and the first setpoint list includes operational setpoints. Before presetting the first setpoint list and sending the first recall instruction to the first distribution network operation control system according to the preset first batch logic, the method includes: preprocessing the preset first setpoint list. The preprocessing includes checking whether the setpoints in the first setpoint list meet a first requirement and a second requirement. The first requirement is to verify whether the IP, ID, setpoint area number, group number, and point number of the setpoints in the first setpoint list are correct according to a preset order. If correct, the first requirement is met. The second requirement is to verify whether the setpoints in all setpoints in the first setpoint list meet a predetermined first safety threshold. If they do, the second requirement is met. Furthermore, the setpoints in the first setpoint list that do not meet the first or second requirement are marked separately and processed according to the first requirement processing logic and the second requirement processing logic; Furthermore, when the setpoints in the first setpoint list meet the first and second requirements, a first recall instruction is sent to the first distribution network operation control system according to the preset first batch logic.

[0032] In this application embodiment, the first requirement is to verify whether the IP, ID, fixed-value area code, group number, and point number of the first fixed-value sheet are correct according to a preset order, that is, to determine whether the number of digits and content format of the IP, ID, fixed-value area code, group number, and point number conform to a preset standard according to a preset order. In an optional embodiment, the number of digits and content format can be as follows: The IP address consists of four numbers between 0 and 255, with each number separated by a dot, for example, "192.168.1.1". Each number occupies one byte, so the entire IP address occupies 32 bits. Usually, the number of digits is not directly specified because its format is fixed. ID (Device Identifier): This can be the device's serial number, model code, or specific identification code. The number of digits and format depend on the system design. For example, it can be an 8-bit or 16-bit hexadecimal number, or a more complex string encoding, such as "DS-RTU-001". In this application embodiment, an 8-bit hexadecimal number is used. The fixed-value area code is used to distinguish the fixed-value configuration sets under different operating modes in the same device. Its number of bits is usually small, set to 1 byte (i.e., 8 bits) in this embodiment, representing a value range of 0 to 255. The content format is usually an unsigned integer. The group number is used to organize and classify telemetry, tele-signaling, and other data for easy management and retrieval. In the IEC 60870-5-101 / 104 specification, the group number is usually one byte, i.e., 8 bits, also ranging from 0 to 255. In this application, the group number is also an 8-bit unsigned integer, with specific values ​​representing different data categories or functional areas. The point number is used to uniquely identify a specific data point, such as a specific telemetry or tele-signaling point. The number of bits in the point number may range from a few bytes to tens of bytes, depending on the number and organization of data points in the system. In this embodiment, the point number is a 16-bit unsigned integer, ranging from 0 to 65535. In more complex systems, a longer numbering structure may be used to support more data points.

[0033] In this embodiment, the second requirement is to verify whether the values ​​in all the value sets in the first value set meet a predetermined first security threshold. Each IP address, ID, value zone number, group number, and point number has a numerical limit range, which determines the value of the first security threshold. For example, an IP address consists of four numbers between 0 and 255, so the first security threshold for an IP address is [0, 255]. An ID (device identifier) ​​is an 8-bit hexadecimal number, so the first security threshold for an ID (device identifier) ​​is [0, 15], where 10 to 15 are represented by A to F. The value range of a value zone number is 0 to 255, so the first security threshold for a value zone number is [0, 255], and so on. By judging the number of bits and content format according to the first requirement, the method for judging the threshold in the second requirement can effectively filter out value sets that do not meet the preset rules, and mark and process them, thereby ensuring the accuracy and reliability of subsequent batch value comparisons.

[0034] In an optional embodiment, the preset order can be IP, ID, fixed area code, group number and point number, or it can be ID, fixed area code, IP, group number and point number, or it can be any sorting order such as group number, point number, IP, ID and fixed area code.

[0035] In this embodiment, the first batch logic includes: prioritizing the value sets in the first value set that meet the first and second requirements; further, prioritizing based on regional criticality level, terminal risk level, power grid operating status, historical recall success rate, and terminal response time; further, prioritizing into first priority, second priority, and third priority; further, sending a first recall instruction to the first distribution network operation control system according to priority order; after the transmission of the first recall instruction corresponding to the first priority value set is completed, generating a first priority completion instruction and transmitting the first recall instruction corresponding to the second priority value set; further, after the transmission of the first recall instruction corresponding to the second priority value set is completed, generating a second priority completion instruction and transmitting the first recall instruction corresponding to the third priority value set; further, after the transmission of the first recall instruction corresponding to the third priority value set is completed, generating a complete instruction.

[0036] Furthermore, the first batch logic also includes: after the transmission of the first recall instruction corresponding to the first priority setting sheet is completed, a first priority completion instruction is generated, and at the same time, a communication link for transmitting the field terminal setting corresponding to the first recall instruction is opened; furthermore, after the transmission of the first recall instruction corresponding to the second priority setting sheet is completed, a second priority completion instruction is generated, and at the same time, a communication link for transmitting the field terminal setting corresponding to the first recall instruction is opened; furthermore, after the transmission of the first recall instruction corresponding to the third priority setting sheet is completed, a third priority completion instruction is generated, and at the same time, a communication link for transmitting the field terminal setting corresponding to the first recall instruction is opened.

[0037] In this embodiment, the priority is divided based on regional criticality level, terminal risk level, power grid operating status, historical call success rate, and terminal response time, including: performing logical scoring on the first setpoint list regarding regional criticality level, terminal risk level, power grid operating status, historical call success rate, and terminal response time; setting thresholds for the logical scores, and setting threshold division constraints regarding regional criticality level, terminal risk level, power grid operating status, historical call success rate, and terminal response time; and prioritizing the setpoint lists in the first setpoint list that meet the first and second requirements based on the threshold division constraints.

[0038] In an optional embodiment, the logical scoring of the first setpoint sheet regarding regional criticality level, terminal risk level, grid operating status, historical call success rate, and terminal response time can be as follows: The regional criticality level reflects the importance of the region in the grid and can be set from 1 to 5 points, with 5 points representing the highest level. For example, 1 point represents a peripheral / rural area, which typically has low population density, little industrial activity, and contributes little to the overall grid's power supply stability and electricity demand. Its importance is relatively low, primarily ensuring basic residential electricity needs. Examples include remote rural areas and agricultural areas. 2 points represent general suburbs, which, compared to peripheral areas, have a certain population and industrial base but are not core economic activity areas. Their importance is moderate, requiring the guarantee of basic living and industrial production power supply. Examples include small towns and suburban residential areas. 3 points represent urban development areas, rapidly developing economic areas containing many commercial and residential areas with a relatively dense population. Their importance is high, requiring high grid reliability and service quality. Examples include emerging business districts and large residential communities. 4. City Center: Highly developed commercial and administrative centers with high population density, containing key facilities such as government agencies and financial institutions. High importance; any disruption could cause significant economic losses and social impact. Examples include central business districts and government administrative areas. 5. Core Urban Areas / Strategic Locations: Core areas at the national or regional level, including political and economic heartlands and locations of facilities crucial to national security. Highest importance; power supply in these areas directly affects national security and social stability. Examples include national capital centers, military command centers, and large data centers.

[0039] Terminal risk level assesses the potential impact of terminal failures on the system, ranging from 1 to 5, with 5 representing extremely high risk. For example, 1 indicates low risk: terminals located at the edge of the grid or on non-critical paths, with a small impact range and negligible effect on the overall system. Examples include branch line terminals serving a small number of users with alternative power sources nearby. 2 indicates relatively low risk: terminals serving a certain number of users, but with backup lines or easily restored power through other means. Examples include distribution transformers in secondary areas with redundant power supply paths nearby. 3 indicates medium risk: terminals located in relatively core areas of the grid, where failures will cause power outages within a certain range, but the impact is controllable and can be mitigated through scheduling adjustments. Examples include some terminals in urban secondary substations, affecting local power supply but not critical services. 4 indicates high risk: terminals carrying important loads or located at critical grid nodes, where failures may lead to large-scale power outages requiring a long recovery time. Examples include terminals supplying power to important facilities such as hospitals and transportation hubs, or substations located at grid bottlenecks. A score of 5 indicates extremely high risk. These are core terminals directly related to the stability and security of the power grid. A failure in these terminals could trigger a chain reaction, severely impacting system operation and even causing widespread blackouts. Repairs are difficult and time-consuming. Examples include key substations in national or regional backbone power grids, and centralized terminals supplying power to numerous critical infrastructure projects. 。

[0040] The power grid's operational status represents its current stability, which can be quantified based on real-time data, scored from 1 to 5, with higher values ​​indicating greater stability. For example, 5 points represents "Very Stable": the grid is operating at its optimal state, all key indicators are within safe limits, there are no emergencies or abnormalities, frequency deviations are minimal, voltage is stable, and reserve capacity is sufficient. 4 points represents "Stable": the grid is operating well, most indicators are normal, occasional slight deviations do not affect system stability, frequency and voltage fluctuations are within acceptable limits, and reserve capacity is moderate. 3 points represents "Moderate": the grid is in a state of alert, facing some challenges, such as loads approaching peak levels in some areas, significant frequency or voltage fluctuations, and low reserve capacity, but overall still manageable. 2 points represents "Unstable": the grid faces significant pressure and clear stability risks, such as frequent voltage or frequency overruns, some areas approaching or reaching transmission limits, and tight reserve capacity. 1 point represents "High Risk": the grid is extremely unstable, facing immediate threats, such as severe overload, large frequency fluctuations, voltage collapse risks, and almost exhausted reserve capacity, requiring emergency intervention.

[0041] Historical recall success rate is the success rate of past recall commands, converted to a percentage. Higher is better, and it's rated from 1 to 5. For example, 5 points is very high: a historical recall success rate of over 90%, indicating that the system or terminal response is very reliable with an extremely low error rate. 4 points is high: a recall success rate of 80%-89%, indicating that the response is successful in most cases, but there is a certain error rate. 3 points is average: a recall success rate of 70%-79%, indicating that the response reliability is average and needs attention and improvement. 2 points is low: a recall success rate of 60%-69%, indicating poor response reliability with obvious problems, requiring immediate improvement. 1 point is very low: a recall success rate below 60%, indicating that the system or terminal response is extremely unreliable and must be investigated and resolved immediately.

[0042] Terminal response time is the average response time; the shorter the better. It can be converted to a score of 1-5, with an extremely short response time being 5. A score of 5 indicates an extremely short response time, far below the set threshold, typically in milliseconds or lower, indicating an extremely fast response. A score of 4 indicates a short response time: the response time is near a low threshold, such as a few milliseconds to tens of milliseconds, demonstrating good response performance. A score of 3 indicates a moderate response time: the response time is at a medium level, such as tens to hundreds of milliseconds, meeting basic requirements but with room for improvement. A score of 2 indicates a slow response time: the response time is relatively long, exceeding one second or even several seconds, beginning to affect system efficiency and user experience. A score of 1 indicates an extremely slow response time: the response time is extremely delayed, far exceeding a reasonable range, severely impacting system functionality and operational responsiveness.

[0043] In an optional embodiment, thresholds are set for the logical scores. The threshold constraints for regional criticality level, terminal risk level, power grid operating status, historical call success rate, and terminal response time are specifically defined as follows: Different scoring intervals and priority thresholds are set for each dimension. For example, the score for each dimension is divided into three intervals (low, medium, and high), with each interval corresponding to a different priority. Assuming the following are example thresholds: When the regional criticality level score is 1-2 points, the priority is low; when the regional criticality level score is 3 points, the priority is medium; when the regional criticality level score is 4-5 points, the priority is high. When the terminal risk level score is 1-2 points, the priority is low; when the regional criticality level score is 3 points, the priority is medium; when the regional criticality level score is 4-5 points, the priority is high. When the power grid operation status score is 1-2 points, the priority is low; when the regional criticality level score is 3 points, the priority is medium; when the regional criticality level score is 4-5 points, the priority is high. When the historical call success rate score is 1-2 points, the priority is low; when the regional criticality level score is 3 points, the priority is medium; when the regional criticality level score is 4-5 points, the priority is high. When the terminal response time score is 1-2 points, the priority is low; when the regional critical level score is 3 points, the priority is medium; and when the regional critical level score is 4-5 points, the priority is high. In an optional embodiment, according to the threshold division constraint, the priority division of the first fixed value list that meets the first requirement and the second requirement can be as follows: When all dimension scores are in the high range, the corresponding first fixed value list is the first priority; when at least one dimension is in the high range and the rest are in the medium or low range, the corresponding first fixed value list is the second priority; when all dimensions are in the low or medium range, the corresponding first fixed value list is the third priority. In an optional embodiment, if they are of the same priority, a secondary priority ranking is performed according to the weighted average. The specific calculation steps of the weighted average can be as follows: Step 1: Collect historical data for each dimension, such as the real-time monitoring value or historical statistical value of regional critical level (Z), terminal risk level (T), power grid operation status (G), historical call success rate (H), and terminal response time (R). The data is preprocessed, including handling missing values, outlier detection and handling, and standardization or normalization. Step 2: Calculate weighting factors. A basic weighting factor is designed for each dimension. This factor is based on the theoretical impact of that dimension on system stability and efficiency, which is fixed but can be manually adjusted to reflect expert knowledge or experience. For example, in this embodiment, BWF is set as follows: z =0.3,BWFT =0.25, BWF G =0.2, BWF H =0.15, BWF R =0.1, Step 3: Real-time Status Adjustment Coefficient. Based on the current system status and data, calculate a real-time adjustment coefficient for each dimension. This coefficient reflects the urgency or importance of the dimension's current impact on the system. For example, if the power grid operation is unstable, the RTC of GG should increase; if the recent recall success rate is high, the RTC of H may decrease. The calculation of RTC can be based on a threshold or ratio, such as adjusting according to the difference or ratio between the real-time value of each indicator and a preset threshold or target value.

[0044] In this embodiment, assuming that the calculation of RTC is based on the standardized real-time value rtv, which ranges from 0 to 1, then RTC = rtv / max(rtvs), where rtvs is the set of standardized real-time values ​​for all dimensions; Step 4: Dynamic weight calculation, combining the basic weight factor and the real-time state adjustment coefficient, calculate the dynamic weight: DW i =BWF i ×RTC i Where i takes values ​​of {1, 2, 3, 4, 5}, representing the regional criticality level, terminal risk level, power grid operating status, historical call success rate, and terminal response time, respectively, i.e., {Z, T, G, H, R}, DW i This represents the corresponding dynamic weight; Step 5: Normalize the total weight. Normalize the dynamic weights of all dimensions to ensure the sum is 1, thus guaranteeing the comparability and reasonableness of the weights. Step 6: The final secondary priority sorting calculation formula is as follows: Where 'a' represents the 'a'-th setpoint in the first setpoint setpoint, and S ai This represents the score value of the i-th item in the a-th fixed value sheet; Step 7: If they are of the same priority, then perform a secondary priority sort based on the weighted average, that is, perform a secondary priority sort based on the size of the secondary priority sorting result.

[0045] It should be noted that the secondary priority ranking calculation not only considers the basic weight factors of each dimension, but also dynamically adjusts the coefficients based on real-time status, making the priority ranking more consistent with the actual situation of the current system. By adjusting the coefficients in real time, the system can flexibly adjust the weights of each dimension according to the current state, thereby more accurately reflecting the impact of each dimension on system stability and efficiency.

[0046] Furthermore, the weighted average calculation method ensures that all dimensions are taken into account, avoiding the limitations of relying on a single dimension to determine priority ranking. This ranking method, which integrates multiple dimensions, can more comprehensively reflect the importance and urgency of the task list, enabling the system to allocate resources and process tasks more rationally.

[0047] By employing secondary priority sorting, the system can more accurately determine the priority order of order placements, thereby optimizing the order in which these orders are invoked and the scheduling strategy. This helps improve system efficiency and stability, reducing unnecessary resource waste and losses. Simultaneously, secondary priority sorting provides system administrators with more flexible and scientific decision-making support, enabling them to better manage and control the system.

[0048] S102, when the first distribution network operation control system receives the first recall instruction, it sends back the field terminal settings corresponding to the first recall instruction; wherein, when the first distribution network operation control system receives the first recall instruction, sending back the field terminal settings corresponding to the first recall instruction includes: if the field terminal settings corresponding to the first recall instruction are not received, the system switches to the backup communication link and resends the first recall instruction; if the field terminal settings corresponding to the first recall instruction are received, the original communication link is considered to be faulty; furthermore, if the field terminal settings corresponding to the first recall instruction are still not received, the system performs remote status diagnosis on the field terminal; if a field terminal fault is diagnosed, a terminal replacement notification is issued, and the system waits for the terminal replacement success information to be sent back after the replacement; when the terminal replacement success information is received, the first recall instruction is resent; if the field terminal settings corresponding to the first recall instruction are received, the original field terminal is considered to be faulty. Furthermore, if the field terminal settings corresponding to the first recall instruction are still not received, it is determined whether other field terminal settings have been updated. If they have been updated, the address information of the setting sheet is considered to be incorrect, and an inspection instruction is sent to the inspection personnel.

[0049] It should be noted that by transmitting the set values ​​back to the field terminals, the system can confirm in real time whether the set values ​​have been successfully recalled to the field terminals, thereby ensuring the timeliness and accuracy of the set value updates. This is crucial for ensuring the stable operation of the power grid, as incorrect set values ​​may lead to improper operation of power grid equipment, thereby triggering a series of potential safety risks.

[0050] In this embodiment, if the field terminal settings are not received within a specified time, the system can automatically switch to a backup communication link and resend the recall command. This function enhances the system's communication reliability and avoids setting update failures due to communication faults. Simultaneously, by switching communication links, the system can promptly detect and resolve communication problems, ensuring the continuity of setting management.

[0051] In this embodiment, if the system fails to successfully transmit the field terminal settings after multiple attempts, it will perform remote status diagnosis on the field terminal. Through diagnosis, the system can determine whether the terminal is faulty and take corresponding measures accordingly. For example, if the diagnosis result indicates a terminal fault, the system will issue a notification to replace the terminal and resend the recall command after the terminal replacement is successful. This process not only improves the system's fault handling capability but also reduces the risk to power grid operation caused by terminal faults.

[0052] In this embodiment, if other field terminal settings have been updated, but the settings for a specific terminal fail to be retrieved, the system can determine that the address information on the setting sheet may be incorrect. In this case, the system will send an inspection instruction to the inspection personnel to promptly detect and correct the address information error. This function helps improve the accuracy of setting management and reduces setting update failures caused by human error or system errors.

[0053] S103. Compare the first setting sheet with the field terminal setting to determine the abnormal and non-abnormal states, and complete the batch verification of the protection setting of the power distribution automation terminal.

[0054] The comparison between the first setting sheet and the field terminal setting includes: extracting the IP, ID, setting area code, group number, and point number from the returned field terminal setting, and recording it as IP. t ID t Zone t Group t Point t At the same time, relevant information is extracted from the operational configuration sheet and recorded as IP. d ID d Zone d Group d Point d Furthermore, each pair of setting sheets is compared with the information of the field terminal according to the transmission order to confirm whether they are consistent; further still, the matching status of each setting sheet is recorded, with consistency marked as True and inconsistency marked as False; In this embodiment of the application, there is a problem with the automatic comparison of the setting of the distribution network automation terminal corresponding to the setting sheet marked as False, and it is necessary to notify the operation and maintenance personnel to perform manual setting comparison remotely.

[0055] Furthermore, a second comparison is performed on inconsistent value sheets. If the second comparison results match, no further operations are performed. If the second comparison results do not match, the mismatched value sheet is output. After all comparisons are completed, a comparison report is generated. The comparison report includes at least the reason for the mismatch and the corresponding value sheet parameter data.

[0056] In this embodiment, the second comparison may include data in the setting sheet other than IP, ID, setting area code, group number, and point number. For example, textual data such as line name, management unit, installation location, and order number may also include variable data such as current, voltage, and delay. The second comparison in this application is designed only for variable data and does not consider textual data. The specific steps are as follows: Step 1, set This represents the actual value of the i-th fixed point in the database. These are the values ​​transmitted back from the field terminal to the corresponding fixed points. The allowable error ranges are denoted as follows: (Regarding current protection thresholds) and (Regarding the delay time); Step 2, Specific Comparison of Setting Values: The judgment condition for comparing current protection thresholds is: for each current protection setting point, check whether the following conditions are met: in, This is the maximum allowable error for the current setting, ensuring that the on-site setting is within the allowable fluctuation range.

[0057] The criteria for comparing delay times are as follows: For delay times, relative error is considered as the standard to ensure time flexibility while maintaining functional security.

[0058] in, This represents the maximum allowable relative error ratio of the delay time to the set value.

[0059] Step 3: Exception Handling and Recording: For each comparison, if the judgment condition is not met, record the exception, including the point number i and the actual value. On-site duty And the amount of error exceeding the tolerance; In an optional embodiment, the anomalies can also be classified, and the anomaly categories can be further subdivided according to the degree and nature of the deviation, such as slight deviation, severe deviation, etc.

[0060] In the embodiments of this application, even if there are slight differences in some setpoints but they are within the allowable range, they should be marked as "normal within the fluctuation range" to distinguish them from completely consistent setpoints.

[0061] Step 4: Comprehensive Judgment and Reporting. Based on the comparison results of all points at a given field terminal, if all points are within the allowable fluctuation range, the result is determined to be "Overall Match, Some Parameters Fluctuate"; if any point exceeds the allowable range, the result is determined to be "Anomaly Exists." All comparison results are summarized, including details of normally matched points, points within the fluctuation range, and anomaly points, to form a detailed comparison report.

[0062] In summary, this invention proposes a method and system for batch verification of protection settings for distribution automation terminals. A first setpoint list is preset, and a first recall instruction is sent to a first distribution network operation control system according to a preset first batch logic. The first recall instruction is a setpoint recall instruction corresponding to the first setpoint list, which includes in-service setpoints. When the first distribution network operation control system receives the first recall instruction, it transmits the field terminal setpoints corresponding to the first recall instruction. The first setpoint list is compared with the field terminal setpoints to determine abnormal and non-abnormal states, thus completing the batch verification of protection settings for distribution automation terminals.

[0063] Firstly, by pre-setting the first batch logic, flexible processing of value setting orders with different priorities can be achieved. Based on the different priorities, the system can intelligently adjust the timing of opening the communication link to ensure that critical and urgent value setting orders are processed first, thereby improving the response speed and operational efficiency of the entire distribution network automation system.

[0064] Secondly, this invention prioritizes value setting orders by comprehensively considering multiple factors such as regional criticality level, terminal risk level, power grid operating status, historical call success rate, and terminal response time. This prioritization method is more scientific and comprehensive, and can more accurately reflect the importance and urgency of value setting orders, providing strong support for subsequent batch value setting comparisons.

[0065] Furthermore, this invention incorporates a robust communication link switching and fault diagnosis mechanism. When the primary communication link fails or fails to receive settings from the field terminal, the system automatically switches to the backup communication link and attempts to resend the recall command. If the settings still cannot be received, the system performs remote status diagnosis of the field terminal and takes appropriate measures based on the diagnosis results. This design ensures the stability and reliability of the system in complex environments.

[0066] Finally, by extracting and comparing information from field terminal settings with those in operation, this invention can accurately identify mismatched setting sheets and generate detailed comparison reports. This helps maintenance personnel quickly locate problems and take targeted measures for repair and optimization.

[0067] In summary, the batch verification method and system for protection settings of distribution automation terminals of the present invention are characterized by intelligence, high efficiency, stability and precision, which can significantly improve the operating efficiency and reliability of distribution network automation systems and provide strong protection for the safe and stable operation of power systems.

[0074] During the comparison process, the focus was on the difference between the on-site terminal setpoint and the in-operation setpoint, and a judgment was made based on the preset allowable fluctuation range. Points that matched normally and were within the fluctuation range were recorded and summarized; abnormal points that exceeded the allowable range were recorded and analyzed in detail.
