[0054] Figure 2 This is a module diagram of the relay protection setting data verification system of the present invention. DETAILED DESCRIPTION

[0055] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0056] In order to solve the problem that the existing relay protection device setting data cannot be effectively ensured to be accurate and cannot provide a strong guarantee for the safe and stable operation of the power system, please refer to Figure 1-Figure 2 , this embodiment provides the following technical solutions:

[0057] A relay protection setting value data verification system includes: an acquisition and comparison module, an error analysis module and a verification and adjustment module.

[0058] Specifically, through the interaction between the acquisition and comparison module, the error analysis module and the verification and adjustment module, the set value data of the relay protection device can be effectively ensured to be accurate, which can provide strong guarantee for the safe and stable operation of the power system.

[0059] The collection and comparison module is used to collect the current fixed value data from the relay protection device, and compare the collected fixed value data with the preset fixed value data item by item, check the differences between the collected fixed value data and the preset fixed value data, record the inconsistent items, and determine the fixed value data comparison results;

[0060] The error analysis module is used to perform error analysis on the comparison results of the set value data, determine whether the error is within the allowable range, mark and process the error that exceeds the allowable range, and determine the verification result of the relay protection set value data;

[0061] Among them, the verification and adjustment module is used to adjust the relay protection set value data according to the verification results of the output relay protection set value data, forming a closed-loop verification management of the relay protection set value data, which can effectively ensure that the set value data of the relay protection device is accurate and provide strong protection for the safe and stable operation of the power system.

[0062] In order to better illustrate the relay protection setting value data verification process, this embodiment now provides a relay protection setting value data verification method, which is implemented based on the above-mentioned relay protection setting value data verification system and includes:

[0063] Collect the fixed value data of the relay protection device and compare the collected fixed value data item by item to determine the fixed value data comparison results;

[0064] In this embodiment, the set value data of the relay protection device is collected and the collected set value data is compared item by item, including:

[0065] Based on intelligent acquisition equipment, the current set value data is collected from the relay protection device, and the preset set value data is obtained as a reference;

[0066] Compare the collected fixed value data with the preset fixed value data item by item, check the differences between the collected fixed value data and the preset fixed value data, and record the inconsistent items, including the fixed value name, current value and standard value, and then determine the fixed value data comparison result.

[0067] In this embodiment, the collected fixed value data is compared with the preset fixed value data item by item, including:

[0068] Extracting the collected fixed value data and the preset fixed value data item by item, and comparing and analyzing the collected fixed value data extracted item by item with the preset fixed value data extracted item by item;

[0069] When the collected fixed value data extracted item by item matches the preset fixed value data extracted item by item, there is no difference between the collected fixed value data extracted item by item and the preset fixed value data extracted item by item, and the consistent items are recorded;

[0070] When the collected fixed value data extracted item by item does not match the preset fixed value data extracted item by item, there is a difference between the collected fixed value data extracted item by item and the preset fixed value data extracted item by item, and the inconsistent item is recorded;

[0071] After all items of comparison and analysis of the collected fixed value data and the preset fixed value data are completed, the comparison results of the fixed value data are determined.

[0072] Specifically, the collected fixed value data is compared with the preset fixed value data item by item, wherein the fixed value data comparison results are shown in Table 1:

[0073] Table 1: Comparison results of fixed value data

[0074]

[0075]

[0076] Therefore, the collected constant value data is compared with the preset constant value data item by item, the differences between the collected constant value data and the preset constant value data are checked, and the inconsistent items are recorded, and then the constant value data comparison results are determined, which is convenient for subsequent error analysis of the constant value data comparison results, and whether the error is within the allowable range. The error that exceeds the allowable range is marked and processed, and then the relay protection constant value data verification result is output.

[0077] Perform error analysis on the comparison results of the set value data to determine whether the error is within the allowable range, mark and process the errors that exceed the allowable range, and output the verification results of the relay protection set value data;

[0078] In this embodiment, error analysis is performed on the fixed value data comparison result to determine whether the error is within the allowable range, and errors that exceed the allowable range are marked and processed, including:

[0079] According to the comparison results of the fixed value data, the current fixed values ​​of all inconsistent items and their corresponding preset values ​​are obtained;

[0080] Perform error analysis on the current values ​​of all inconsistent items and their corresponding preset values, and calculate the errors of all inconsistent items;

[0081] According to the preset error tolerance range, determine whether the error of each inconsistent item with differences is within the error tolerance range, and mark and process the errors of inconsistent items that exceed the error tolerance range, and then output the relay protection setting data verification results, including a detailed list of consistency and inconsistency.

[0082] In this embodiment, determining whether the error of each inconsistent item is within an allowable error range includes:

[0083] The errors of all inconsistent items with differences are extracted one by one, and the errors of the inconsistent items with differences extracted one by one are compared and analyzed with the preset error tolerance range;

[0084] When the errors of the inconsistent items extracted one by one are within a preset error tolerance range, the errors of the inconsistent items extracted one by one are recorded;

[0085] When the errors of the inconsistent items extracted one by one with differences are not within a preset error tolerance range, the errors of the inconsistent items extracted one by one with differences are marked and processed.

[0086] Specifically, it is determined whether the error of each inconsistent item with differences is within the allowable error range. The results of processing the errors of the inconsistent items with differences are shown in Table 2:

[0087] Table 2: Results of error processing for inconsistent items with differences

[0088]

[0089] Therefore, by performing error analysis on the constant value data comparison results, it is determined whether the error is within the allowable range, and the errors that exceed the allowable range are marked and processed, and then the relay protection constant value data verification results are output, so that adjustment suggestions can be provided based on the relay protection constant value data verification results to adjust the relay protection constant value data. This can effectively ensure that the constant value data of the relay protection device is accurate and can provide strong protection for the safe and stable operation of the power system.

[0090] According to the verification results of the relay protection setting data, the relay protection setting data is adjusted to form a closed-loop verification management of the relay protection setting data.

[0091] In this embodiment, the relay protection setting data is adjusted according to the relay protection setting data verification result, including:

[0092] According to the verification results of the output relay protection constant value data, the inconsistent items that exceed the allowable error range are analyzed, the adjustment amount of the constant value data of the inconsistent items that exceed the allowable error range is automatically calculated, and adjustment suggestions are provided. The relay protection constant value data is adjusted according to the adjustment suggestions.

[0093] Specifically, the inconsistent items that exceed the allowable error range are analyzed, and the adjustment amount of the fixed value data of the inconsistent items that exceed the allowable error range is automatically calculated, including:

[0094] Retrieve the inconsistent items that exceed the error tolerance as the target items;

[0095] Extract the error tolerance of each target item and obtain the error tolerance of each target item;

[0096] According to the actual error between the fixed value data of each target item and the preset value corresponding to the target item;

[0097] Extracting the excess ratio of the actual error of the target item beyond the allowable error range;

[0098] Extracting the actual duration of time during which the actual error of the target item exceeds the allowable error range;

[0099] Comparing the actual duration of the time during which the actual error of the target item exceeds the allowable error range with a preset duration reference value, and obtaining a ratio between the actual duration of the time during which the actual error of the target item exceeds the allowable error range and the preset duration reference value;

[0100] comparing the ratio of the actual duration of time during which the actual error of the target item exceeds the allowable error range to a preset reference value of the duration, and the excess ratio of the actual error of the target item exceeding the allowable error range;

[0101] When the ratio between the actual duration of time during which the actual error of the target item exceeds the allowable error range and the preset duration reference value does not exceed the excess ratio of the actual error of the target item exceeding the allowable error range, the excess ratio of the actual error of the target item exceeding the allowable error range is used as the corresponding ratio of the adjustment amount of the fixed value data of the target item;

[0102] When the ratio between the actual duration of the actual error of the target item exceeding the allowable error range and the preset duration reference value exceeds the excess ratio of the actual error of the target item exceeding the allowable error range, the corresponding ratio of the adjustment amount of the fixed value data of the target item is set.

[0103] The technical effect of the above-mentioned technical solution is as follows: This solution first retrieves the target item that exceeds the allowable error range and extracts information such as the allowable error range, actual error, excess ratio, and actual duration. Through multi-dimensional analysis, the error situation is accurately grasped, providing an accurate basis for subsequent calculation of the adjustment amount, avoiding inaccurate adjustments caused by incomplete error analysis. The corresponding adjustment ratio is determined based on the ratio of the actual duration of the actual error exceeding the allowable error range to a preset reference duration, and the comparison result of the excess ratio. This approach comprehensively considers the error level and duration, ensuring that the adjustment amount better meets actual needs, improving the accuracy of fixed value data adjustments, and thus enhancing the overall accuracy of the system. Processing inconsistent items that exceed the allowable error range can promptly identify and resolve data inaccuracies in the system, preventing the accumulation of errors from affecting normal system operation, ensuring system stability and reliability, and reducing the risk of failure caused by data errors. Taking into account the actual duration of the actual error exceeding the allowable error range can dynamically adapt to error changes. Different durations reflect the different severity and development trends of the error. This approach enables timely and appropriate adjustments to fixed value data, ensuring reliable system operation in the face of changing errors. This solution automatically analyzes items that fall outside the tolerance range and calculates adjustments, eliminating the need for excessive human intervention. This reduces manual analysis and calculation time and effort, improves processing efficiency, and enables the system to quickly respond to and address data errors. It focuses on target items that fall outside the tolerance range and performs analysis and calculations on these key items, avoiding indiscriminate processing of all data. This improves targeted processing, reduces unnecessary operations, and further enhances processing efficiency.

[0104] Specifically, the corresponding ratio of the adjustment amount of the fixed value data of the target item is set, including:

[0105] Extracting the ratio between the actual duration of the target item's actual error exceeding the error allowable range and the preset duration reference value;

[0106] The ratio by which the actual error of the extracted target item exceeds the allowable error range;

[0107] Obtaining a corresponding ratio of the adjustment amount of the fixed value data of the target item by using a ratio between an actual duration during which the actual error of the target item exceeds the allowable error range and a preset duration reference value and a ratio by which the actual error of the target item exceeds the allowable error range;

[0108] The corresponding ratio of the adjustment amount of the fixed value data of the target item is obtained by the following formula:

[0109]

[0110] Wherein, B represents the corresponding ratio of the adjustment amount of the fixed value data of the target item; Y represents the ratio between the actual duration of the actual error of the target item exceeding the error allowable range and the preset duration reference value; E represents the excess ratio of the actual error of the target item exceeding the error allowable range; It is a measure of the relative relationship between the two while taking into account the factors of time and amplitude. Multiply This may be to map this metric value to a suitable interval for subsequent processing by the sine function. The previously calculated value is used as the input to the sine function to convert the metric value after integrating time and amplitude factors into a value within a reasonable proportional range. This means mapping the calculated result to a relatively smooth and bounded range to represent the corresponding adjustment ratio, thus avoiding unreasonably large or small adjustment ratio values. This formula comprehensively considers both the time factor (Y) and the amplitude factor (E) when the error exceeds the allowable range. Compared to considering only one factor, it more comprehensively reflects the actual error situation of the target item, making the obtained corresponding adjustment ratio more scientific and reasonable, thereby improving the accuracy of the system's error handling. Leveraging the characteristics of the sine function, the calculated result of the combined factors is converted into the corresponding adjustment ratio, resulting in relatively smooth changes in the adjustment ratio. This avoids sudden changes in the adjustment ratio caused by simplistic calculations, which can lead to system instability, thereby enhancing system stability. The sine function limits the result to [-1, 1], defining a reasonable range for the corresponding adjustment ratio, preventing extreme cases of over- or under-adjustment, helping to maintain stable system operation and providing a relatively appropriate adjustment ratio under various error scenarios, thus improving the system's adaptability.

[0111] Retrieve the actual error of the target item;

[0112] Obtaining the adjustment amount of the fixed value data corresponding to the target item by using the corresponding ratio of the adjustment amount of the fixed value data of the target item in combination with the actual error of the target item;

[0113] The adjustment amount of the fixed value data is obtained by the following formula:

[0114] R=[1-B*sign(E s )]*E s

[0115] Among them, R represents the adjustment amount of the fixed value data; B represents the corresponding ratio of the adjustment amount of the fixed value data of the target item; E s Indicates the actual error of the target item. B*sign(E s) is to combine the adjustment ratio with the error sign. It calibrates the direction of the adjustment ratio B according to the positive or negative error, so that the adjustment amount can be adjusted accordingly according to the error direction. For example, when the error is positive or negative, even if the B value is the same, the calculation results of this part will be different due to the effect of the sign function, thus affecting the calculation of the final adjustment amount. This is to combine the coefficients related to the error direction and adjustment ratio obtained earlier with the actual error E s Multiplication. Essentially, the final fixed-value data adjustment, R, is calculated based on the error magnitude, direction, and adjustment ratio. This calculation method ensures that the adjustment reflects both the magnitude of the error and the appropriate adjustment based on the adjustment ratio and direction. The formula distinguishes between positive and negative errors, allowing the adjustment calculation to consider whether the actual error is too large or too small. This results in more targeted adjustments, improved accuracy, and avoids blind adjustments. Incorporating the corresponding ratio, B, into the calculation allows the adjustment to be dynamically adjusted based on the overall error of the target item (B reflects the combined influence of factors such as time and magnitude). Different values ​​of B scale the adjustment to varying degrees based on the error, helping to determine the appropriate adjustment in various error scenarios and improving system adaptability. The formula's calculation method does not simply use the error value or the adjustment ratio directly, but rather organically combines them through a series of operations. This ensures relatively smooth changes in the adjustment, preventing drastic fluctuations due to small fluctuations in the error or adjustment ratio. This enhances system stability and promotes smooth operation.

[0116] The technical effect of the above-described technical solution is that by considering the ratio of the duration of the target item's actual error exceeding the allowable error range to a preset reference value, as well as the excess ratio, a more comprehensive and accurate assessment of the target item's error can be achieved. This makes the setting of the corresponding ratio for the fixed-value data adjustment more scientific and reasonable. Consequently, the fixed-value data adjustment calculated based on the actual error more accurately reflects the actual system status, helping to improve the accuracy of the system's output results. This solution integrates multiple factors to determine the fixed-value data adjustment, avoiding the potential over- or under-adjustment problems that can arise from adjustments based solely on a single factor. For example, considering both the duration and the excess ratio can prevent unnecessary drastic adjustments due to short-term, large errors, or the impact on system stability caused by long-term, small errors that are not promptly adjusted. Properly setting the adjustment helps maintain stable system operation and reduce fluctuations and oscillations. Dynamic adjustment of the fixed-value data based on the specific circumstances of the target item's actual error allows the system to better adapt to varying operating conditions and environmental changes. Whether the error fluctuates significantly or remains relatively stable, adjustments can be made according to the pre-set rules, improving the system's adaptability and robustness to various complex operating conditions. The specific process from acquiring error information to calculating adjustment values ​​has been clarified, enabling the system to quickly respond to actual error conditions and adjust fixed value data in a timely manner. In particular, when the error exceeds the allowable range, the adjustment value can be quickly calculated and adjusted according to the established ratio, shortening the system's response time and improving its real-time and dynamic performance.

[0117] In this embodiment, closed-loop verification management of relay protection setting data is formed, including:

[0118] The adjusted relay protection setting data is monitored in real time, and the relay protection setting data is optimized based on the monitoring feedback, forming a closed-loop verification management of the relay protection setting data, and generating a relay protection setting data verification report, which is displayed to management personnel in a visual form.

[0119] In summary, the current constant value data is collected from the relay protection device, and the preset constant value data is obtained as a reference. The collected constant value data is compared with the preset constant value data item by item, the differences between the collected constant value data and the preset constant value data are checked, and the inconsistent items are recorded, and then the constant value data comparison results are determined. By performing error analysis on the constant value data comparison results, it is determined whether the error is within the allowable range, and the errors exceeding the allowable range are marked and processed, and then the relay protection constant value data verification results are output, and adjustment suggestions are provided according to the relay protection constant value data verification results. By adjusting the relay protection constant value data, it can be effectively ensured that the constant value data of the relay protection device is accurate, which can provide a strong guarantee for the safe and stable operation of the power system.
