[0002] Lightning strike is the main cause of transmission line tripping. For the lightning protection evaluation model of transmission lines, in the prior art, the simulation step length needs to be set by the user.

In order to ensure that the evaluation of all towers does not report an error, the manually set simulation step length, even if the calculation does not report an error through continuous attempts, will be a relatively small time step length, which is likely to cause a large waste of computing resources.

[0030] Embodiment 1

[0031] Figure 1 This is a flowchart of a method for calculating the lightning protection analysis simulation step length provided in Embodiment 1 of the present invention. This embodiment is applicable to the situation of analyzing the lightning protection performance of a tower. This method can be executed by a device for calculating the lightning protection analysis simulation step length, which can be implemented in the form of hardware and / or software, and the device for calculating the lightning protection analysis simulation step length can be configured in an electronic device. As Figure 1 shown, the method includes:

[0032] S110. Obtain a description file of the tower model.

[0033] A pole tower refers to a support used to hold transmission lines in an overhead power transmission line. A pole tower model refers to a mathematical model established for the pole tower. Through the pole tower model, the performance of the pole tower can be simulated and analyzed. In this application, the performance of the pole tower can be lightning protection performance, that is, the ability of the pole tower to withstand lightning current. Exemplarily, when lightning strikes the pole tower, it can be regarded as inputting lightning current into the pole tower to form an overvoltage. The greater the lightning current, the higher the overvoltage formed. When the overvoltage is too high for the pole tower to withstand, a power transmission line trip will occur. Among them, the lightning current refers to the current that flows through the struck object and discharges into the ground during direct lightning strike.

[0034] A description file refers to a file that describes the parameters of the pole tower model. The parameters of the pole tower model include at least one of parameters such as pole tower size and topological structure. The pole tower size refers to the actual geometric size of the pole tower. The topological structure refers to the connection structure of the equivalent circuit of the pole tower. The pole tower equivalent circuit is formed by connecting a series of impedance elements. By determining the numbers of each connected node, the topological structure of the pole tower equivalent circuit can be described through the node numbers. Among them, an impedance element refers to an element used to describe the impedance of the pole tower. The parameters of the pole tower model can be preset default values or can be set according to actual situations. The description file is automatically generated after the pole tower model is established.

[0035] Specifically, when performing lightning protection performance analysis on the pole tower, at least one pole tower model is established through simulation software, and the pole tower models are connected to simulate an actual power transmission line. According to the at least one established pole tower model, the corresponding description files of each pole tower model can be obtained. One pole tower model corresponds to one description file. The description files corresponding to different pole tower models can be the same or different.

[0036] S120. Query the length data of the impedance element in the description file.

[0037] The length data refers to the length of the impedance element. The impedance size of the impedance element can be described through the length data. Exemplarily, the larger the length data, the greater the impedance of the impedance element. The description file includes at least the length data of one impedance element. The length data of each impedance element can be the same or different.

[0038] Specifically, query the fields in the description file to identify the length data of the impedance element. Exemplarily, the data of a preset data type can be directly extracted from the description file and used as the length data of the impedance element; or a string used to describe the length data of the impedance element can be extracted from the description file, and the string can be converted into data of a preset data type and used as the length data of the impedance element. The preset data type can be double-precision floating-point numbers.

[0039] S130. Determine the simulation step size for lightning protection analysis according to the length data.

[0040] Lightning protection analysis refers to analyzing the lightning protection performance of a tower to obtain the maximum lightning current that the tower can withstand. The simulation step size of lightning protection analysis refers to the interval time between two consecutive calculation processes of the tower model during the lightning protection analysis process. One calculation process of the tower model refers to the process of starting from inputting the lightning current into the tower model, calculating the overvoltage of the tower according to the lightning current, and comparing the overvoltage with a preset voltage to obtain a comparison result. Among them, the preset voltage can be set according to the actual situation. The comparison result can be normal and abnormal, and abnormal indicates that the tower trips.

[0041] Specifically, according to the length data, the length data can be substituted into the calculation formula of the simulation step size to calculate the simulation step size of lightning protection analysis, or the length data can be processed, and the simulation step size of lightning protection analysis can be calculated according to the processed length data.

[0042] The technical solution of the embodiment of the present invention realizes the automatic calculation of the simulation step size by obtaining the description file of the tower model, querying the length data of the impedance element in the description file, and determining the simulation step size of lightning protection analysis according to the length data. It can improve the efficiency of calculating the simulation step size and reduce the manual workload. By querying the length data of the impedance element in the description file of the tower model, the simulation step size can be determined for the tower model, solving the problem in the prior art that the simulation step size needs to be determined according to the lengths of the impedance elements of all towers on the entire line, resulting in a too small set simulation step size and serious waste of computing resources. It can reasonably set the simulation step size, improve the accuracy of calculating the simulation step size, and reduce the waste of computing resources.

[0043] Embodiment Two

[0044] Figure 2 It is a flowchart of a method for calculating the simulation step size of lightning protection analysis provided by the second embodiment of the present invention. On the basis of the above embodiment, querying the length data of the impedance element in the description file is specifically: querying the target information corresponding to the length identification field in the description file; obtaining the length data of the impedance element from the target information. As Figure 2 shown, the method includes:

[0045] S210. Obtain the description file of the tower model.

[0046] S220. Query the target information corresponding to the length identification field in the description file.

[0047] The length identification field is used to identify the position of the information describing the length data. Exemplarily, the length identification field may include a first start field and a first end field. The first start field is used to identify the start position of the information describing the length data, and the first end field is used to identify the end position of the information describing the length data.

[0048] The target information refers to the information describing the length data. The target information can be the code in the description file. At least one length data can be obtained through the target information. The target information corresponding to the length identification field refers to the target information determined according to the length identification field. Exemplarily, the target information corresponding to the length identification field can be the information between the first start field and the first end field in the length identification field.

[0049] Specifically, in the description file, query the length identification field, and determine the position where the target information is located according to the length identification field, so as to determine the target information corresponding to the length identification field. Exemplarily, the length identification field includes a first start field <resistancelengths>and the first end field< / resistancelengths> , and determine the start and end positions of the target information according to the first start field and the first end field, and the information between the first start field and the first end field is the target information corresponding to the length identification field.

[0050] S230. Obtain the length data of the impedance element from the target information.

[0051] Specifically, identify the target information, obtain the field for identifying the length data in the target information, and obtain the length data of the impedance element according to the field for identifying the length data. The target information includes at least one group of fields for identifying the length data. According to a group of fields for identifying the length data, the length data of one impedance element can be determined. A group of fields for identifying the length data includes a second start field and a second end field, and the length data of the impedance element can be determined according to the information between the second start field and the second end field. Exemplarily, a group of fields for identifying the length data includes a second start field <string>and the second end field< / string> , <string>and< / string> The information between can be determined as the length data of the impedance element

[0052] S240. Determine the lightning protection analysis simulation step according to the length data.

[0053] The technical solution of the embodiment of the present invention realizes automatically querying the target information in the description file by querying the target information corresponding to the length identification field in the description file and obtaining the length data of the impedance element from the target information, which can improve the efficiency of obtaining the target information, thereby improving the efficiency of obtaining the length data of the impedance element and reducing the manual workload.

[0054] Based on the above embodiment, the obtaining the length data from the target information includes: identifying at least one line information included in the target information, and obtaining the length data of at least one impedance element, where different impedance elements correspond to different line information.

[0055] Line information refers to the information corresponding to a line of code in the code corresponding to the target information. It can also be understood that the target information corresponds to at least one line of code, and each line of code corresponds to one line of information, so the target information includes at least one line of information. Specifically, the line information included in the target information is identified line by line. In each line, the field of the identification length data in the line information is identified, and according to the field of the identification length data, the length data of the impedance element is obtained. After the target information is identified, at least one length data of the impedance element can be obtained. Among them, one line of information includes the length data of one impedance element, that is, different impedance elements correspond to different line information. According to the line sequence of the line information, it can be determined which impedance element the length data included in the line information belongs to. It can also be understood that according to the line sequence of the line information, the impedance element corresponding to the length data can be determined, and the corresponding relationship between the length data and the impedance element can be preset in advance.

[0056] By identifying at least one line of information included in the target information line by line and obtaining at least one length data of the impedance element, it is convenient to establish the corresponding relationship between the length data and the impedance element and improve the accuracy of obtaining the length data.

[0057] Embodiment III

[0058] Figure 3 The flowchart of a method for calculating the lightning protection analysis simulation step provided in Embodiment III of the present invention is shown. On the basis of the above embodiments, the step of determining the lightning protection analysis simulation step according to the length data is specifically: calculating an initial simulation step according to the length data; and correcting the initial simulation step to obtain the lightning protection analysis simulation step. As Figure 3 shown, the method includes:

[0059] S310. Obtain the description file of the tower model.

[0060] S320. Query the length data of the impedance element in the description file.

[0061] S330. Calculate the initial simulation step according to the length data.

[0062] The initial simulation step refers to the simulation step calculated according to the length data, and the initial simulation step can provide a reference basis for determining the lightning protection analysis simulation step.

[0063] Specifically, one simulation step can be calculated according to one length data. First, at least one simulation step can be calculated according to at least one length data, and then the obtained simulation steps are screened to obtain the initial simulation step; or the length data can be screened first, and then the initial simulation step is calculated according to the screened length data. According to multiple length data, finally only one initial simulation step can be obtained.

[0064] S340. Modify the initial simulation step size to obtain the lightning protection analysis simulation step size.

[0065] Specifically, modify the initial simulation step size and determine the modified initial simulation step size as the lightning protection analysis simulation step size. Exemplarily, modifying the initial simulation step size can be to enlarge or reduce the initial simulation step size within a preset range, and the preset range can be set according to the actual situation.

[0066] The technical solution of this embodiment calculates the initial simulation step size through the length data and modifies the simulation step size to obtain the lightning protection analysis simulation step size, which can avoid the influence of calculation errors on the setting of the lightning protection analysis simulation step size, improve the accuracy of determining the lightning protection analysis simulation step size, and reduce the waste of computing resources.

[0067] Based on the above embodiment, calculating the initial simulation step size according to the length data includes: obtaining the minimum length data among the length data of at least one of the impedance elements; calculating the initial simulation step size based on the following formula according to the minimum length data: , where T is the initial simulation step size, L is the minimum length data, and c is the speed of light.

[0068] The minimum length data refers to the minimum value in the length data. Specifically, sort the length data of at least one impedance element, obtain the length data with the smallest value as the minimum length data, and substitute the minimum length data into the initial simulation step size calculation formula to calculate the initial simulation step size.

[0069] By selecting the minimum length data from the length data of the impedance elements and calculating the initial simulation step size according to the minimum length data, the calculation amount of the initial simulation step size can be reduced, computing resources can be saved, and the calculation efficiency of the initial simulation step size can be improved.

[0070] Based on the above embodiment, modifying the initial simulation step size to obtain the lightning protection analysis simulation step size includes: reducing the initial simulation step size through a preset parameter to obtain an alternative simulation step size; mapping the alternative simulation step size to a preset standard numerical range to obtain the lightning protection analysis simulation step size, and the preset standard numerical range is determined according to a preset minimum transmission time.

[0071] The preset parameter refers to the parameter set according to the actual situation for reducing and adjusting the initial simulation step size. The alternative simulation step size refers to the simulation step size after reducing the initial simulation step size. The preset standard numerical range refers to the value range of the simulation step size determined according to the minimum transmission time. Exemplarily, the preset standard numerical range is less than the minimum transmission time. The transmission time refers to the time required for the current to flow from one end to the other end through the impedance element. The transmission time is determined by the parameters of the impedance element itself. The minimum transmission time refers to the minimum value of the transmission times of each impedance element.

[0072] Specifically, according to the preset parameter, divide the initial simulation step size by the preset parameter to obtain the alternative simulation step size. Map the alternative simulation step size into the preset standard numerical range, and determine the lightning protection analysis simulation step size as the mapping result. Exemplarily, the preset parameter is 1.1. Divide the initial simulation step size by 1.1 to obtain the alternative simulation step size. Represent the alternative simulation step size in scientific notation, that is, a*10 n , where 1≤a<10. If a is an integer, the alternative simulation step size can be directly determined as the lightning protection analysis simulation step size. Otherwise, round a down to obtain an integer b, and use b*10 n as the lightning protection analysis simulation step size.

[0073] Reducing the initial simulation step size through the preset parameter to obtain the alternative simulation step size, and mapping the alternative simulation step size into the preset standard numerical range to obtain the lightning protection analysis simulation step size can solve the problem in the prior art that the set lightning protection analysis simulation step size is greater than the minimum transmission time due to the decimal place retention problem, and improve the accuracy of determining the lightning protection analysis simulation step size.

[0074] Based on the above embodiments, it further includes: according to the lightning protection analysis simulation step size, input a lightning current into the tower model to obtain the lightning protection performance of the tower model.

[0075] Specifically, starting from the first time a lightning current is input into the tower model, input a lightning current into the tower model every other lightning protection analysis simulation step size. The lightning current input each time gradually increases, and the increasing amplitude can be set according to the actual situation. After the tower receives the lightning current, calculate the overvoltage of the tower according to the lightning current, and compare the overvoltage with the preset voltage. If the overvoltage is less than the preset voltage, it indicates that the comparison result is normal, and continue to input the next lightning current. If the overvoltage is greater than the preset voltage, it indicates that the corresponding result is abnormal, and the lightning protection analysis process ends. The lightning protection performance of the tower can be determined according to the magnitude of the last input lightning current or the last output overvoltage.

[0076] According to the lightning protection analysis step size, lightning current is input into the tower model to obtain the lightning protection performance of the tower model, realizing the simulation study of the lightning protection performance of the tower and providing a data basis for improving the lightning protection performance of the tower.

[0080] Among them, the description file of the tower model contains the code for describing the length data of the impedance elements. Exemplarily, the code for describing the length data of the impedance elements is:

[0081]

[0082] Among them, L_ZA1, L_ZA2, L_ZA3, L_ZA4, L_ZA5, L_ZA6, L_ZT1, and L_ZT are the lengths of the respective impedance elements in the equivalent circuit of the tower corresponding to the tower model, which are set by the user when establishing the tower model.

[0083] S420. Query the target information corresponding to the length identification field in the description file.

[0084] Specifically, identify the <resistancelengths>field and< / resistancelengths> field in the description file, and determine the target information according to the <resistancelengths>field and< / resistancelengths> code between the fields.

[0085] S430. Identify the target information line by line to obtain the length data of at least one impedance element.

[0086] Specifically, extract the <string>and< / string> string between them line by line, convert it into a double-precision floating-point number, determine it as the length data of the impedance element, and store the length data of at least one impedance element as an impedance length array.

[0087] S440. Obtain the minimum length data among the length data of at least one impedance element.

[0088] Specifically, compare the numerical values in the impedance length array to obtain the minimum length data L.

[0089] S450. Calculate the initial simulation step size according to the minimum length data.

[0090] Specifically, substitute the minimum length data into the initial simulation step size calculation formula to obtain the initial simulation step size T.

[0091] S460. Modify the initial simulation step size to obtain the simulation step size for lightning protection analysis.

[0092] Specifically, divide T by 1.1 and express the result in scientific notation, i.e., a*10 n , where 1 ≤ a < 10; if a is an integer, keep it unchanged, otherwise, round a down to get an integer b. Finally, use b*10 n as the simulation step size for lightning protection analysis.

[0093] The technical solution of the embodiment of the present invention realizes the automatic calculation of the simulation step size by obtaining the description file of the tower model, querying the length data of the impedance element in the description file, and determining the simulation step size for lightning protection analysis according to the length data. It can improve the efficiency of calculating the simulation step size, reduce the manual workload, and determine the simulation step size for the tower model by querying the length data of the impedance element in the description file of the tower model, solving the problem in the prior art that the simulation step size needs to be determined according to the lengths of the impedance elements of all towers on the entire line, resulting in a too small set simulation step size and serious waste of computing resources.
