[0066] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0067] Existing techniques rely on experimental comparisons of pulse effects to select coil parameters. This approach suffers from low efficiency, poor accuracy, and poor adaptability. To address this, this application provides a large-scale model-based query statement conversion method. This method uses a constructed electromagnetic-magnetic-mechanical coupling model to compare the pulse effects of different coil parameter combinations, thereby optimizing the coil parameters.

[0068] See also Figure 1 As shown, the embodiment of the present application discloses a deicing method based on optimized pulse coil parameters, including:

[0069] Step S11: constructing a target electric-magnetic-force coupling model corresponding to an electric pulse deicing device; the electric pulse deicing device includes a pulse coil.

[0070] In this embodiment, the pulse coil and eddy current multiplier in the electric pulse deicing device can first be simplified based on the magnetic field interface in the preset simulation software, so that the pulse coil and eddy current multiplier are equivalent to a first circular plate and a second circular plate, respectively; wherein the size of the first circular plate is the same as the size of the pulse coil; the size of the second circular plate is the same as the size of the eddy current multiplier; and the eddy current multiplier is used to amplify eddy currents. Then, a preset initial spacing is set between the first circular plate and the second circular plate, and based on the first circular plate, the second circular plate and the preset initial spacing, and using the preset simulation software, a target electro-magnetic-force coupling model is constructed. Furthermore, a finite element region corresponding to the target electro-magnetic-force coupling model can be set according to the overall size formed by the first circular plate and the second circular plate, so that the target electro-magnetic-force coupling model is calculated within the finite element region; wherein the region size of the finite element region is larger than the overall size formed by the first circular plate and the second circular plate.

[0071] It is understandable that when establishing a target electro-magnetic-force coupling model using pre-defined simulation software, such as COMSOL (a widely used multi-physics simulation software), the electric pulse force is primarily generated between the coil and the multiplier. Therefore, only the coil and the multiplier can be considered during modeling. Furthermore, the coil itself is relatively irregular, and the coil wire diameter and turn spacing are extremely small. Meshing the coil when establishing the target electro-magnetic-force coupling model will result in extremely small meshes, increasing the computational effort and lengthening the calculation time. Therefore, the magnetic field interface in the COMSOL simulation software can be used to equate the coil and multiplier to a first circular plate and a second circular plate. The number of turns corresponding to the first circular plate is set to the actual number of turns of the coil, and the initial spacing between the first and second circular plates can be set to 1 mm. For example, the actual coil model and the equivalent coil model are shown in Figure 2.

[0072] It should be noted that when the multiplier is made of aluminum, the electric pulse deicing device has a better deicing effect. Therefore, when establishing the target electro-magnetic-force coupling model, the corresponding materials of the coil and multiplier can be set to the same as the actual object. For example, the material corresponding to the multiplier can be set to aluminum. Since the actual coil is composed of copper and an insulating layer, the coil has been simplified in the target electro-magnetic-force coupling model, ignoring its insulating layer. Therefore, the material of the simplified coil can be set to copper. At the same time, the initial radius of the multiplier can be set to 75mm and the thickness to 8mm, and the parameters of the coil can be set to an inner diameter of 7mm, an outer diameter of 27mm, and a thickness of 4mm.

[0073] Since the magnetic field is unbounded, a finite element region can be set for the target electromagnetic-magnetic-mechanical coupling model to limit the calculation range of the model. For example, in this embodiment, the overall shape of the coil and multiplier is cylindrical, with a radius of 100 mm and a height of 70 mm. The size of the finite element region can be slightly larger than the overall size of the coil and multiplier, as shown in Figure 3, where the gray area in Figure 3 (a) is the finite element region.

[0074] Step S12: determining the pulse current of the electric pulse deicing device when performing deicing.

[0075] In this embodiment, to simplify the calculation process, a Rogowski coil may be used to measure and collect the pulse current of the electric pulse deicing device during deicing, and the pulse current may be used as the input of the target electromagnetic-magnetic-mechanical coupling model.

[0076] Specifically, when an electric pulse deicing device is used for deicing, a pulse power supply is used to discharge the pulse coil in the electric pulse deicing device, the measurement result of the Rogowski coil placed on the pulse coil lead in the electric pulse deicing device is determined, and the measurement result is converted into a pulse current to input the pulse current into the target electromagnetic-magnetic-force coupling model.

[0077] Step S13: input the pulse current into the target electro-magnetic-force coupling model, so that the target electro-magnetic-force coupling model uses its own pulse coil model to obtain the pulse current and generate a magnetic field, and applies the generated magnetic field to its own eddy current multiplier model to generate eddy currents, and generates pulse forces corresponding to different coil parameter combinations through the interaction between the eddy currents and the magnetic field; wherein any coil parameter combination includes the number of coil turns, the outer diameter of the coil, and the axial length of the coil.

[0078] In this embodiment, the pulse coil is one of the main parts of the electric pulse deicing device. The coil parameters will affect the coil's inductance and resistance, and thus affect the deicing effect of the electric pulse deicing device. The coil is in the shape of a pancake structure. When optimizing the coil parameters, the number of turns, outer diameter, and axial length of the coil are mainly considered. Figure 4 As shown, d1 is the outer diameter of the coil, d2 is the inner diameter of the coil, d is the average diameter of the coil, r is the effective length of the coil cross section, and a is the axial length of the coil, that is, the width of the enameled wire used to wind the coil. The parameters satisfy d=(d1+d2) / 2, r=(d1-d2) / 2.

[0079] The expression for coil inductance is:

[0080] ;

[0081] in, is the vacuum permeability, N is the number of coil turns, Determined by the ratio ρ=r / d, F is affected by a and is determined by ρ=r / d and γ=r / a.

[0082] The expression for coil resistance is:

[0083] ;

[0084] Where ρ is the conductor resistivity, L is the length of the enameled wire used to wind the coil, and S is the cross-sectional area of the enameled wire.

[0085] Traditional coil parameter optimization requires extensive trial and error testing, which is costly and inefficient. This embodiment uses simulation software to systematically vary key coil parameters (number of turns, outer diameter, and axial length) to batch calculate the pulse forces corresponding to different coil parameter combinations, improving efficiency.

[0086] It should be noted that the target parameter relationship can be used to determine the number of coil turns and the outer diameter of the coil in any coil parameter combination;

[0087] Among them, the target parameter relationship is:

[0088] r2=r1+n*k;

[0089] Here, r2 is the coil's outer diameter, r1 is its inner diameter, n is the number of turns, and k is a pre-set coefficient. The coil's outer diameter and number of turns are related. Although the winding process may have errors, the coil's outer diameter, inner diameter, and number of turns generally satisfy the target parameter relationship described above. Therefore, optimizing the number of turns will also optimize the coil's outer diameter. Furthermore, a parametric sweep of the coil's axial length is also necessary.

[0090] If the coil size is too large, the overall size of the electric pulse deicing device will also increase, further increasing material consumption and weight. Therefore, the coil turns can be set within 70 turns and parametrically swept in increments of 5 turns. The outer diameter of the coil satisfies the target parameter relationship described above. By setting the outer diameter as an expression related to the number of turns, a parametric sweep of the number of turns and the outer diameter can be performed simultaneously. If the axial length of the coil is too large, the coil slot will also increase accordingly, further increasing material costs. Therefore, the maximum axial length of the coil can be set to 4mm and parametrically swept in increments of 0.5mm.

[0091] For each set of coil parameters, the target electromagnetic-magnetic-force coupling model can be automatically called to calculate the pulse force, avoiding manual parameter modification and repeated modeling, and improving optimization efficiency.

[0092] Step S14: determining a target coil parameter combination based on the pulse forces corresponding to the different coil parameter combinations, and using the target coil parameter combination as the optimized coil parameters.

[0093] In a specific embodiment, the pulse forces under different coil parameter combinations can be compared, and the coil parameter combination with the maximum pulse force can be determined as the target coil parameter combination. For example, the pulse effect is best when the coil has 60 turns and an axial length of 4 mm. At this time, the outer diameter of the coil is 65 mm, and the induced eddy current distribution and pulse force are as follows: Figure 5 and Figure 6 shown.

[0094] In another specific embodiment, a magnetic field intensity map for different coil parameter combinations can be first determined using preset simulation software. The uniformity of the magnetic field distribution on the eddy current multiplier surface for each of these coil parameter combinations can then be determined based on the magnetic field intensity map. A target coil parameter combination can then be determined using a pre-set optimal parameter determination criterion based on the corresponding pulse force for each of these coil parameter combinations and the uniformity of the magnetic field distribution on the eddy current multiplier surface for each of these coil parameter combinations.

[0095] In this way, the coil parameters are selected comprehensively based on the magnetic field distribution and pulse force waveform during the electric pulse deicing process under different coil parameters, thereby efficiently screening out the optimal coil parameters.

[0096] Step S15: Optimize the pulse coil in the electric pulse deicing device using the optimized coil parameters, and perform deicing operations based on the optimized electric pulse deicing device.

[0097] In this embodiment, by selecting and optimizing coil parameters, an electric pulse deicing device with better deicing effect is designed. When ice is applied to the overhead ground wire, the electric pulse deicing device can be used to perform electric pulse deicing to ensure the safe operation of the power grid.

[0098] As can be seen from the above, this embodiment simultaneously considers the number of turns, outer diameter, and axial length of the coil, and compares the pulse force generated by the coil under different parameter combinations, thereby efficiently and accurately selecting and optimizing the coil parameters.

[0099] See also Figure 7 As shown, the embodiment of the present application further discloses a deicing device based on optimized pulse coil parameters, comprising:

[0100] A model building module 11 is used to build a target electric-magnetic-mechanical coupling model corresponding to an electric pulse deicing device; the electric pulse deicing device includes a pulse coil;

[0101] a current determination module 12, configured to determine a pulse current when the electric pulse deicing device is performing deicing;

[0102] a pulse force acquisition module 13, configured to input the pulse current into the target electro-magnetic-force coupling model, so that the target electro-magnetic-force coupling model uses its own pulse coil model to acquire the pulse current and generate a magnetic field, and applies the generated magnetic field to its own eddy current multiplier model to generate eddy currents, and generate pulse forces corresponding to different coil parameter combinations through the interaction between the eddy currents and the magnetic field; wherein any coil parameter combination includes the number of coil turns, the outer diameter of the coil, and the axial length of the coil;

[0104] The deicing module 15 is configured to optimize the pulse coil in the electric pulse deicing device using the optimized coil parameters, and perform deicing operations based on the optimized electric pulse deicing device.

[0105] From the above, it can be seen that the present application equates the actual pulse coil to a pulse coil model, avoiding the problem of overly dense meshing caused by the small wire diameter and turn spacing of the actual pulse coil, reducing the amount of calculation, and improving the simulation speed. By establishing a target electro-magnetic-force coupling model, considering the interaction between the pulse coil and the eddy current multiplier, the pulse force generation mechanism is accurately simulated to avoid the blindness of traditional experience adjustment. The actual pulse current is measured by the Rogowski coil as the model input to ensure that the simulation is close to the actual working conditions and to improve the reliability and adaptability of the optimization results. Comparing the pulse force size under different coil parameter combinations and finding the optimal coil parameter combination solves the problem of low efficiency of experimental optimization. In this way, the present application can efficiently and accurately select and optimize the coil parameters, and then design an electric pulse deicing device with better deicing effect, so as to use the optimized electric pulse deicing device for deicing operations.
