Description

Technical Field

[0001] The present application relates to the technical field of sheath induced voltage identification of multi-circuit parallel cables, and in particular to a method, device and computer equipment for optimizing structural parameters of a filled core cable. Background Art

[0002] With the development of China's economy, the demand for electricity is growing. As the main force of power transmission, the use of high-voltage cables is also increasing year by year. The utilization rate of cable materials on the market is not high, the cable cost is high, and the large-scale laying of high-voltage cables has caused a lot of economic losses. Therefore, a more economical cable structure is needed to solve the problem of high cable cost.

[0003] The traditional way to reduce cable costs is to add filler cores to the cables to reduce the main costs of the cables. However, since the traditional method of adding filler cores is based on the ability of existing equipment to excavate the hollow excavation data of cable conductors, the structure and size of the filler cores are not suitable for the actual application environment of the cable, thus adding filler cores to the cable conductors reduces the actual power transmission efficiency of the cable.

[0072] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0073] The method for optimizing the structural parameters of a filling core cable provided in an embodiment of the present application can be applied to the application environment of a cable structure device. The method can be applied to a terminal, a server, or a system including a terminal and a server, and can be implemented through the interaction between the terminal and the server. The terminal can be, but is not limited to, various personal computers, laptops, etc. The terminal identifies the hollow hole data of the cable through the simulation process of the cable structure model of the cable, thereby generating a filling cable structure model corresponding to each filling core. Then, each filling cable structure model is subjected to a cable simulation test process respectively, thereby analyzing the model performance of each filling cable structure model. Finally, based on the analysis results, the target cable structure parameters of each cable under each filling core condition are identified. Thus, the scheme obtains the optimal size of the applicable filling core through simulation and experiment, greatly reduces the current transmission loss of the cable after the filling core is filled, and then identifies the target cable structure parameters of the cable under each filling core condition by testing different filling cable structure models respectively, thereby providing the user with the optimal filling core structure parameters for screening different filling cores, improving the range of screening filling cores, and the structural optimization effect of each filling core. When different filling cores are added to the cable conductor, the actual power transmission efficiency of the cable can be ensured.

[0074] In an exemplary embodiment, Figure 1 As shown, a method for optimizing the structural parameters of a filling core cable is provided, and the method is applied to a terminal as an example for explanation, including the following steps S101 to S104. Among them:

[0075] Step S101, obtaining a cable structure model of the cable and structural material data of each filling core, and simulating the current transmission process of the cable based on the cable structure model to obtain current distribution information of the cable.

[0076] In this embodiment, the terminal obtains the cable structure parameters of the cable and the service environment data of the cable, and constructs the cable structure model of the cable through the finite element simulation model. Among them, the cable structure parameters include the structural parameters corresponding to the three-dimensional structure data of each substructure of the cable. Among them, the substructure includes but is not limited to the substructures such as the sheath structure, the core structure, and the isolation structure. Then, the terminal obtains the structural material data of the filling core that can be filled into the cable, wherein each filling core includes but is not limited to the filling core corresponding to the materials such as hollow aluminum, copper-clad aluminum or polyethylene. Among them, the structural material data of each filling core includes the physical properties of the filling core, and the physical properties are not limited to the performance data such as resistivity, current carrying capacity, conductivity, mechanical strength, thermal conductivity and corrosion resistance. Finally, the terminal simulates the current transmission process of the cable based on the cable structure model to obtain the current distribution information of the cable. Among them, the current distribution information is the current transmission amount of each position range in the cross-sectional structure diagram of the cable. Because the conductor transmission process is affected by the skin effect, the current transmission amount near the edge of the fiber core in the core structure of the cable is large, while the current transmission amount near the center of the fiber core is small, or there is no current transmission. The specific identification process will be described in detail later.

[0077] Step S102, based on the current distribution information, the hollow hole data of the cable is calculated through the filling core applicable algorithm, and the filling core parameters of each filling core are generated based on the structural material data of each filling core. This algorithm mainly considers the current distribution and thermal characteristics of the cable. First, according to the cable specifications, the maximum and minimum values ​​of the inner and outer diameters of the cable are input, and the current carrying capacity of the cable is input at the same time. The objective function is set as follows:

[0078]

[0079] In the formula, is the maximum temperature in the cable, is the average temperature of the cable, is the maximum current density in the cable, is the average current density in the cable. At the same time, consider the constraints such as the inner and outer diameters are between the maximum and minimum values, and the current is less than the maximum current carrying capacity. The Lagrange square method is used for optimization, and the principle construction formula L is:

[0080]

[0081] By solving the partial derivatives and solving the system of equations, we get the following system of equations:

[0082]

[0083] Finally, the optimal radius of the cavity in the middle of the cable is obtained, which can make the current density and cable temperature rise relatively small.

[0084] In this embodiment, the terminal calculates the hollow hole data of the cable based on the current distribution information through the filling core applicable algorithm, and generates the filling core parameters of each filling core based on the structural material data of each filling core. Among them, the hollow hole data includes the hollow hole edge data of the cable and the hollow hole range data of the cable. The specific calculation process will be described in detail later. Finally, the terminal generates the filling core parameters of each filling core based on the structural material data of each filling core. The way to generate the filling core parameters is to generate the filling core parameters corresponding to each structural material data through the parameter conversion program corresponding to the COMSOL Multiphysics software.

[0085] Step S103, based on the parameters of each filling core and the hollow hole data of the cable, adjust the cable structure model to obtain the filled cable structure model corresponding to each filling core, and based on the filled cable structure model corresponding to each filling core, simulate the test process of each filled cable structure model through the cable simulation test strategy to obtain the simulation test result of each filled cable structure model.

[0086] In this embodiment, the terminal adjusts the cable structure model based on the parameters of each filling core and the hollow hole data of the cable to obtain the filling cable structure model corresponding to each filling core, and based on the filling cable structure model corresponding to each filling core, simulates the test process of each filling cable structure model through a cable simulation test strategy to obtain the simulation test results of each filling cable structure model. Among them, the cable simulation test strategy includes simulation test strategies for each sub-cable of each shielding structure mode of the filling core at each shielding structure parameter. Among them, the cable simulation test strategy is used to identify the performance test results of the filling core under different shielding structure conditions through simulation experiments. The specific simulation process will be described in detail later.

[0087] Step S104: identifying target cable structural parameters of the cable under various core-filling conditions based on the simulation test results.

[0088] In this embodiment, the terminal identifies target cable structural parameters of the cable under various core-filling conditions based on various simulation test results.

[0089] Based on the above scheme, the hollow hole data of the cable is identified through the simulation process of the cable structure model of the cable, so as to generate the filled cable structure model corresponding to each filling core. Then, each filled cable structure model is subjected to cable simulation test processing respectively, so as to analyze the model performance of each filled cable structure model. Finally, based on the analysis results, the target cable structure parameters of each cable under each filling core condition are identified. Thus, this scheme obtains the optimal size of the applicable filling core through simulation and experiment, greatly reduces the current transmission loss of the cable after the filling core is filled, and then identifies the target cable structure parameters of the cable under each filling core condition by testing different filling cable structure models respectively, thereby providing users with the optimal filling core structure parameters for screening different filling cores, improving the range of screening filling cores, and the structural optimization effect of each filling core. When adding different filling cores to the cable conductor, the actual power transmission efficiency of the cable can be ensured.

[0090] Optionally, based on the cable structure model, the current transmission process of the cable is simulated to obtain the current distribution information of the cable, including: collecting cable operation data of the cable, and identifying cable operation parameters of the cable based on the cable operation data; inputting the cable operation parameters into the cable structure model, simulating the current transmission process of the cable to obtain the simulated operation data of the cable, and based on the simulated operation data, performing current distribution arrangement processing in the cross-sectional structure diagram of the cable to obtain the current distribution information of the cable.

[0091] In this embodiment, the terminal collects the cable operation data of the cable, and identifies the cable operation parameters of the cable based on the cable operation data. The terminal presets a conversion correspondence relationship of converting each cable operation data into the cable operation parameter, and then the terminal identifies the cable operation parameter corresponding to the cable operation data by querying the correspondence relationship. The cable operation parameters include but are not limited to parameter values ​​corresponding to data such as transmission current value, transmission voltage value, and current transmission amount.

[0092] Then, the terminal inputs the cable operation parameters into the cable structure model, simulates the current transmission process of the cable, obtains the simulation operation data of the cable, and performs current distribution arrangement processing in the cross-sectional structure diagram of the cable based on the simulation operation data to obtain the current distribution information of the cable. The cross-sectional structure diagram of the cable is a structure diagram corresponding to the cross-sectional structure model of the cable cross section in the cable structure model of the cable. The simulation operation data of the cable includes the current transmission amount at each position point in the conductor of the cable.

[0093] Based on the above scheme, after simulating the cable operation data of the cable, the obtained simulation operation data is distributed and arranged in the cross-sectional structure diagram of the cable, thereby improving the accuracy and comprehensiveness of the obtained current distribution information.

[0094] Optionally, based on the current distribution information, the hollow hole data of the cable is calculated by applying a core filling algorithm, including: based on the current distribution information, dividing the cross-sectional structure diagram of the cable into structural grids to obtain various grid areas of the cable; based on each grid area, using a core filling algorithm to calculate the hollow hole edge data of the cable and the hollow hole range data of the cable; using the hollow hole edge data of the cable and the hollow hole range data of the cable as the hollow hole data of the cable.

[0095] In this embodiment, the terminal performs structural grid division on the cross-sectional structure diagram of the cable based on the current distribution information to obtain each grid area of ​​the cable. The grid area is grid-divided in the order from outside to inside and from the current transmission amount from large to small. In the grid after division, the grid area near the edge of the conductor is smaller, and the grid area near the center area of ​​the conductor is larger. The shape of the grid can be a triangle, a square, or other polygonal shapes. The shape can be adjusted according to the setting of the staff, and the grid division method can be processed by the finite element simulation model.

[0096] Based on each grid area, the terminal calculates the hollow hole edge data and the hollow hole range data of the cable by filling the core applicable algorithm. The hollow hole edge data is the position information of the edge of the hollow hole in the cable core conductor. The hollow hole range data is the range position of the range of the hollow hole in the cable core conductor, etc.

[0097] Finally, the terminal uses the hollow hole edge data of the cable and the hollow hole range data of the cable as the hollow hole data of the cable.

[0098] Based on the above scheme, after the grid is split according to the current distribution information, the edge data of the cable's hollow hole and the range data of the cable's hollow hole are identified, thereby improving the accuracy of identifying the cable's hollow hole data.

[0099] Optionally, filling core parameters of each filling core are generated based on the structural material data of each filling core, including: for each filling core, based on the structural material data of the filling core, identifying the structural performance data of each structural physical property type of the filling core; converting the structural performance data of each structural physical property type into performance parameters of each structural physical property type through a data parameterization program; and using the performance parameters of all structural physical property types as the filling core parameters of the filling core.

[0100] In this embodiment, the terminal identifies the structural performance data of each structural physical performance type of the filling core based on the structural material data of the filling core for each filling core, wherein the physical performance type includes but is not limited to a supporting performance type, a conductive performance type, a thermal conductive performance type, an electromagnetic blocking performance type, and the like.

[0101] Then, the terminal converts the structural performance data of each structural physical performance type into performance parameters of each structural physical performance type through a data parameterization program. The data parameter conversion program is the data parameter conversion program in the COMSOL Multiphysics software described above. Finally, the terminal uses the performance parameters of all structural physical performance types as the filling core parameters of the filling core.

[0102] Based on the above scheme, the structural performance data of each structural physical performance type is parameterized to identify the filling core parameters, thereby improving the accuracy and comprehensiveness of the identification.

[0103] Optionally, based on each filling core parameter and the hollow hole data of the cable, the cable structural model is adjusted to obtain a filled cable structural model corresponding to each filling core, including: based on the hollow hole data of the cable, identifying the hollow hole model of the cable in the cable structural model of the cable; for each filling core parameter, based on the performance parameters of each structural physical property type of the filling core, replacing each model parameter of the hollow hole model to obtain a filling core model corresponding to the filling core; replacing the hollow hole model in the cable structural model with the filling core model to obtain a filled cable structural model corresponding to the filling core model.

[0104] In this embodiment, the terminal identifies the hollow hole model of the cable in the cable structure model of the cable based on the hollow hole data of the cable. Then, the terminal replaces the model parameters of the hollow hole model based on the performance parameters of each structural physical performance type of the filling core for each filling core parameter, and obtains a filling core model corresponding to the filling core. Among them, the method of replacing each model parameter of the hollow hole model is to adjust the model parameters at the hollow hole model to the filling core parameters of each structural physical performance type of each filling core in the modeling program of the finite element simulation model, so as to obtain a filling core model corresponding to each filling core. Finally, the terminal replaces the hollow hole model in the cable structure model with each filling core model to obtain a filled cable structure model corresponding to each filling core model.

[0105] Based on the above scheme, after identifying the hollow cavity model, the filling cable structure model corresponding to each filling core model is identified by replacing parameters, thereby improving the comprehensiveness and accuracy of the identification.

[0106] Optionally, based on the filled cable structural model corresponding to each filling core, the test process of each filled cable structural model is simulated through the cable simulation test strategy to obtain the simulation test results of each filled cable structural model, including: obtaining each shielding structure mode of the cable and each performance test process of the cable, and based on each shielding structure mode and each performance test process, generating each sub-cable simulation test strategy for each shielding structure mode at each shielding structure parameter; for each filled cable structural model, based on the shielding structure mode, adjusting the shielding structure parameters of the filled cable structural model to obtain the target filled cable structural model corresponding to each shielding structure mode; based on the each sub-cable simulation test strategy corresponding to each shielding structure mode, through the target filled cable structural model corresponding to each shielding structure mode, performing performance test processing on each target filled cable structural model to obtain each performance test result corresponding to each shielding structure mode; taking each performance test result corresponding to all shielding structure modes as the simulation test result of the filled cable structural model.

[0107] In this embodiment, the terminal obtains each shielding structure mode of the cable and each performance test process of the cable, and based on each shielding structure mode and each performance test process, generates each sub-cable simulation test strategy for each shielding structure mode at each shielding structure parameter. Among them, the shielding structure mode includes but is not limited to copper tape shielding, braided shielding and double-layer shielding and other shielding modes. Among them, the performance test process includes but is not limited to the test mode corresponding to the electromagnetic interference test, conducted interference test, radiation test, field test, frequency response analysis and other methods. Among them, the simulation test strategy of each sub-cable at each shielding structure parameter includes each shielding structure mode, and the simulation test strategy of each sub-cable at different shielding parameters. Among them, different shielding parameters, for example, different shielding layer thicknesses, different weaving methods, and different shielding layer parameter values. The simulation test strategy of each sub-cable includes the simulation test strategy corresponding to different performance test processes.

[0108] For each filled cable structure model, the terminal adjusts the shielding structure parameters of the filled cable structure model based on the shielding structure mode to obtain the target filled cable structure model corresponding to each shielding structure mode. The shielding structure parameters of the adjusted filled cable structure model are the model parameters of the filling core model in the filled cable structure model. Specifically, the terminal adds the shielding structure parameters corresponding to each shielding structure mode to the model parameters of each filling core model to obtain the target filled cable structure model corresponding to each shielding structure mode.

[0109] Then, based on the simulation test strategies of each sub-cable corresponding to each shielding structure mode, the terminal performs performance test processing on each target filled cable structure model through the target filled cable structure model corresponding to each shielding structure mode, and obtains each performance test result corresponding to each shielding structure mode. Among them, the performance test result includes the test results of different performance test processes. Finally, the terminal uses the performance test results corresponding to all shielding structure modes as the simulation test results of the filled cable structure model.

[0110] Based on the above scheme, by identifying the sub-simulation test strategies corresponding to each shielding structure mode of the filling core, the performance of each shielding structure parameter of different shielding structure modes is tested, thereby improving the comprehensiveness and accuracy of identifying the shielding performance of each shielding structure mode.

[0111] Optionally, based on each simulation test result, the target cable structural parameters of the cable under each filled core condition are identified, including: for each filled cable structural model, based on the performance test results corresponding to each shielding structure mode of the filled cable structural model, identifying the performance evaluation value of each shielding structure mode at each shielding structure parameter through the performance evaluation strategy corresponding to each performance test process; screening the shielding structure parameters corresponding to the highest performance evaluation value of each shielding structure mode as the target shielding structure parameters of each shielding structure mode, and simulating the current transmission process of the filled cable structural model including each target shielding structure parameter to obtain the transmission loss value corresponding to each target shielding structure parameter; screening the cable structural parameters of the filled cable structural model including the target shielding structure parameters corresponding to the lowest transmission loss value as the target cable structural parameters of the cable under the filled core condition corresponding to the filled cable structural model.

[0112] In this embodiment, the terminal identifies the performance evaluation value of each shielding structure mode at each shielding structure parameter for each filled cable structure model based on each performance test result corresponding to each shielding structure mode of the filled cable structure model and through the performance evaluation strategy corresponding to each performance test process. The performance evaluation strategy corresponding to each performance test process is preset in the terminal, and the evaluation strategy, for example, includes the performance evaluation value corresponding to each performance test result range, so that the terminal identifies the performance evaluation value of each shielding structure mode at each shielding structure parameter by querying the performance test result range to which the performance test result belongs.

[0113] The terminal selects the shielding structure parameters corresponding to the highest performance evaluation value of each shielding structure mode as the target shielding structure parameters of each shielding structure mode, and simulates the current transmission process of the filled cable structure model containing each target shielding structure parameter to obtain the transmission loss value corresponding to each target shielding structure parameter. Among them, the current transmission process in the simulated current transmission process is the same process as the current transmission process of the cable simulated above. No redundant description is given here.

[0114] Specifically, copper tape shielding is an electromagnetic shielding technology. The calculation formula for the transmission loss method corresponding to this technology is:

[0115]

[0116] Where TL is the transmission loss in dB. , They are input power and output, both in W. Ideally, copper tape shielding should exhibit high losses at most frequencies.

[0117] Braided shielding is a type of cable or wire shielding method, mainly used to reduce the impact of electromagnetic interference and radio frequency interference. Generally, multiple strands of fine wires are twisted together to form a braided shielding layer, which is used to wrap around the outside of the cable or wire. Through its tight mesh structure, it provides a low-resistance grounding path for the cable. When the electromagnetic field tries to penetrate the cable, the metal wires in the braided layer will guide these electromagnetic fields and dissipate them to the ground, thereby reducing the impact on the internal signal. Braided shielding has the advantages of strong high-frequency interference shielding ability, high flexibility, strong durability, and good grounding effect. The effect of braided shielding is related to the braiding coverage. The greater the coverage, the better the shielding effect. The calculation formula is as follows:

[0118]

[0119] Among them, P is the braiding coverage, C is the number of bundles in the braided layer, d is the braided monofilament diameter, and D is the cable diameter before braiding.

[0120] The effect of braided shielding can also be measured by shielding effectiveness, which can be calculated by the following formula:

[0121]

[0122] Among them, SE is the braided shielding effect, V r 、V c They are the reference voltage and coupling voltage respectively, both in V.

[0123] Double shielding is a shielding layer with two different materials or structures in electronic equipment or cables. It is mainly used to reduce the impact of electromagnetic interference and electromagnetic radiation and ensure the stability and safety of signal transmission. The main methods to check whether the double shielding is intact are performance testing and environmental adaptability testing. Performance testing is divided into shielding effectiveness testing and signal transmission testing. Shielding effectiveness testing is generally tested according to GB / T12190-2006 as the standard to measure the shielding effectiveness of the double shielding body within a specific frequency range. The signal transmission test transmits the signal in a double shielding environment to observe whether the signal quality is stable and whether there is obvious attenuation or interference to determine whether the double shielding is qualified. Environmental adaptability testing is divided into temperature adaptability testing, humidity adaptability testing, and electromagnetic environment adaptability testing. The temperature adaptability test generally places the double shielding body in different temperature environments for testing to observe whether its shielding effectiveness changes. The smaller the change, the better the temperature adaptability. The humidity adaptability test generally places the double shielding body in a high humidity environment for testing to observe whether it has corrosion, oxidation, etc. Electromagnetic environment adaptability testing generally places the double-layer shield in a strong electromagnetic field environment to test whether it can effectively isolate external electromagnetic interference. Due to the complex mathematical expressions and physical quantities of the double-layer shielding design, there is currently no specific and detailed calculation formula for direct calculation. The simplified calculation formula for the double-layer shielding effectiveness is as follows:

[0124]

[0125] Among them, SE total It represents the total shielding effectiveness of the double-layer shielding, SE1 and SE2 represent the individual effectiveness of the first and second layers of shielding respectively, and M represents the contribution of multiple reflections between layers to the shielding effectiveness. This item usually needs to be calculated based on specific physical models and geometric parameters.

[0126] Finally, the terminal screens the cable structural parameters of the filled cable structural model including the target shielding structural parameters corresponding to the minimum transmission loss value as the target cable structural parameters of the cable under the filled core condition corresponding to the filled cable structural model.

[0127] Based on the above scheme, after the performance simulation, the current transmission simulation is performed to screen the target cable structure parameters under the filling core conditions corresponding to each filled cable structure model, thereby improving the accuracy of screening, the range of screening filling cores, and the structural optimization effect of each filling core. This ensures that when different filling cores are added to the cable conductor, the actual power transmission efficiency of the cable can be ensured.

[0128] This application also provides an example of cable structure optimization design, such as Figure 2 As shown, the specific processing process includes the following steps:

[0129] Step S201, obtaining a cable structure model of the cable and structural material data of each filling core.

[0130] Step S202: collecting cable operation data of the cable, and identifying cable operation parameters of the cable based on the cable operation data.

[0132] Step S204, based on the current distribution information, the cross-sectional structure diagram of the cable is divided into structural grids to obtain grid areas of the cable.

[0133] Step S205, based on each grid area, the hollow hole edge data of the cable and the hollow hole range data of the cable are calculated by using a filling core applicable algorithm.

[0134] Step S206, taking the cable hollow hole edge data and the cable hollow hole range data as the cable hollow hole data.

[0135] Step S207 : for each filling core, based on the structural material data of the filling core, identifying the structural property data of each structural physical property type of the filling core.

[0136] Step S208, converting the structural performance data of each structural physical performance type into performance parameters of each structural physical performance type through a data parameterization program.

[0137] Step S209, taking the performance parameters of all structural physical performance types as the filling core parameters of the filling core.

[0138] Step S210, based on the hollow hole data of the cable, identifying the hollow hole model of the cable in the cable structure model of the cable.

[0139] Step S211 , for each filling core parameter, based on the performance parameters of each structural physical performance type of the filling core, the model parameters of the hollow model are replaced to obtain a filling core model corresponding to the filling core.

[0140] Step S212: Replace the hollow hole model in the cable structure model with the filled core model to obtain a filled cable structure model corresponding to the filled core model.

[0141] Step S213, obtaining each shielding structure mode of the cable and each performance test process of the cable, and based on each shielding structure mode and each performance test process, generating each sub-cable simulation test strategy for each shielding structure mode at each shielding structure parameter.

[0142] Step S214, for each filled cable structure model, based on the shielding structure mode, the shielding structure parameters of the filled cable structure model are adjusted to obtain the target filled cable structure model corresponding to each shielding structure mode.

[0143] Step S215, based on the simulation test strategies of each sub-cable corresponding to each shielding structure mode, through the target filling cable structure model corresponding to each shielding structure mode, performance test processing is performed on each target filling cable structure model to obtain the performance test results corresponding to each shielding structure mode.
