[0002] With the development of flexible DC transmission technology, a flexible DC transmission technology based on pure opto-current transformers has emerged.

[0003] In the above technical solutions, there have been multiple incidents where internal discharge in the flange section of the optical fiber insulator in the pure optical current transformer has led to insulation failure, which in turn has damaged the pure optical current transformer. Therefore, it is necessary to optimize the material conductivity parameters in the optical fiber insulator. However, the optimized material conductivity parameters require a large number of experiments to determine, which will waste a lot of manpower and resources. Moreover, due to limitations in experimental conditions and other factors, the accuracy of the final results will also be greatly affected, making the determination of the optimal material conductivity parameters for the optical fiber insulator very inefficient.

[0042] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0043] It should be noted that the terms "first" and "second" used in the embodiments of the present invention are merely to distinguish similar objects and do not represent a specific ordering of objects. It is understood that "first" and "second" can be interchanged in a specific order or sequence where permissible. It should be understood that the objects distinguished by "first" and "second" can be interchanged where appropriate so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0044] In one embodiment, such as Figure 1 As shown, a method for determining the conductivity parameter of optical fiber insulator materials is provided. This embodiment illustrates the application of this method to a terminal. It is understood that this method can also be applied to a server, and further to a system including both a terminal and a server, and implemented through interaction between the terminal and the server. In this embodiment, the method includes the following steps:

[0045] Step S101: Obtain multiple material conductivity parameters pre-set for the optical fiber insulator, and input each material conductivity parameter into the pre-constructed optical fiber insulator material conductivity parameter determination model.

[0046] In this system, the fiber optic insulator is the main structure of the pure opto-current transformer. Flexible DC transmission requires current transformers with high sampling accuracy, fast response speed, and wide measurement range, and pure opto-current transformers are widely used in flexible DC transmission due to these characteristics. The material conductivity parameters refer to the conductivity of materials such as the filler grease and fiber sheath in the fiber optic insulator. The multiple material conductivity parameters are randomly set within a pre-defined threshold range. The pre-constructed model for determining the material conductivity parameters of the fiber optic insulator is a pre-constructed three-dimensional model of the fiber optic insulator, which sets the voltage boundary conditions for the fiber optic insulator.

[0047] Specifically, multiple sets of material conductivity parameters are randomly set within the threshold range of material conductivity parameters, including the conductivity of materials such as filler paste and fiber sheath in optical fiber insulators. These multiple sets of material conductivity parameters are then input into a pre-constructed optical fiber insulator material conductivity parameter determination model. The voltage boundary conditions of the optical fiber insulator set by this model are used to simulate the operation of the optical fiber insulator. Each set of material conductivity parameters corresponds to one simulation, resulting in simulation result data corresponding to each set of material conductivity parameters.

[0048] Step S102: By using the optical fiber insulator material conductivity parameter determination model, obtain the optical fiber insulator electric field information corresponding to the conductivity parameters of each material, and filter out the target optical fiber insulator electric field information within the preset range from the electric field information of each optical fiber insulator.

[0049] The electric field information of the optical fiber insulator refers to the maximum electric field strength between every two materials in the optical fiber insulator. For example, the electric field information of the optical fiber insulator could be the maximum electric field strength at the interface between the optical fiber sheath and the optical fiber coating. The preset range is a pre-defined reasonable range of electric field strength; electric field information of the optical fiber insulator outside the preset range is invalid data. Then, the target electric field information of the optical fiber insulator is the electric field information of the optical fiber insulator within the preset range.

[0050] Specifically, the voltage boundary conditions of the model are determined by the conductivity parameters of the fiber optic insulator material, the operation of the fiber optic insulator is simulated, the electric field information of the fiber optic insulator corresponding to the conductivity parameters of each material is obtained, and the electric field information of the target fiber optic insulator within the preset range is selected.

[0051] Step S103: Obtain the maximum sub-electric field information among the multiple sub-electric field information contained in the target optical fiber insulator electric field information, and filter out the final optical fiber insulator electric field information with the smallest maximum sub-electric field information from the target optical fiber insulator electric field information.

[0052] Among them, the electric field information of the optical fiber insulator is the maximum electric field strength between every two materials in the multiple materials of the optical fiber insulator. That is to say, the electric field information of the optical fiber insulator includes multiple maximum electric field strengths, and the sub-electric field information is any one of the multiple maximum electric field strengths. As for the maximum sub-electric field information, it is the largest of the multiple maximum electric field strengths. In other words, each target optical fiber insulator electric field information has a maximum sub-electric field information. Finally, the final optical fiber insulator electric field information is the target optical fiber insulator electric field information with the smallest maximum sub-electric field information among all the target optical fiber insulator electric field information.

[0053] Specifically, the maximum sub-electric field information among multiple sub-electric field information contained in the target fiber optic insulator's electric field information is obtained, and the final fiber optic insulator electric field information with the smallest maximum sub-electric field information is selected from the target fiber optic insulator electric field information. For example, there are four groups of target fiber optic insulator electric field information: A, B, C, and D. The multiple sub-electric field information corresponding to group A are A1, A2, and A3, respectively; the multiple sub-electric field information corresponding to group B are B1, B2, and B3, respectively; the multiple sub-electric field information corresponding to group C are C1, C2, and C3, respectively; and the multiple sub-electric field information corresponding to group D are D1, D2, and D3, respectively. If a comparison shows that max{A1, A2, A3} > max{B1, B2, B3} > max{C1, C2, C3} > max{D1, D2, D3}, then the target fiber optic insulator electric field information of group D is taken as the final fiber optic insulator electric field information.

[0054] Step S104: The material conductivity parameter corresponding to the final electric field information of the optical fiber insulator is used as the final material conductivity parameter of the optical fiber insulator.

[0055] Among them, the final material conductivity parameter is the most reasonable material conductivity parameter for optical fiber insulators.

[0056] Specifically, the material conductivity parameter corresponding to the final electric field information of the optical fiber insulator is the final material conductivity parameter of the optical fiber insulator.

[0057] In the above-mentioned method for determining the conductivity parameters of optical fiber insulator materials, multiple pre-defined conductivity parameters for optical fiber insulators are obtained, and each conductivity parameter is input into a pre-constructed optical fiber insulator material conductivity parameter determination model. Through the optical fiber insulator material conductivity parameter determination model, the electric field information of the optical fiber insulator corresponding to each conductivity parameter is obtained. From these electric field information, the target optical fiber insulator electric field information within a preset range is selected. The maximum sub-electric field information among the multiple sub-electric field information contained in the target optical fiber insulator electric field information is obtained, and the final optical fiber insulator electric field information with the smallest maximum sub-electric field information is selected from the target optical fiber insulator electric field information. The material conductivity parameter corresponding to the final optical fiber insulator electric field information is then used as the final material conductivity parameter of the optical fiber insulator. This application uses a pre-constructed model to determine the conductivity parameters of optical fiber insulator materials. It obtains the electric field information of optical fiber insulators corresponding to multiple pre-set material conductivity parameters, then filters out the target optical fiber insulator electric field information within a preset range, and then filters out the final optical fiber insulator electric field information with the smallest maximum electric field information. Finally, it uses the material conductivity parameter corresponding to the final optical fiber insulator electric field information as the final material conductivity parameter, which can efficiently determine the optimal material conductivity parameter of the optical fiber insulator.

[0058] In one embodiment, the electric field information of the optical fiber insulator includes: the maximum first electric field strength at the interface between the optical fiber sheath and the optical fiber coating layer of the optical fiber insulator; the maximum second electric field strength at the interface between the filler paste and the optical fiber sheath of the optical fiber insulator; and the maximum third electric field strength at the interface between the epoxy core rod and the filler paste of the optical fiber insulator. Selecting the target optical fiber insulator electric field information within a preset range from the various optical fiber insulator electric field information includes the following steps:

[0059] From the electric field information of each fiber optic insulator, the electric field information of the target fiber optic insulator, where the maximum first electric field strength, the maximum second electric field strength, and the maximum third electric field strength are all within the preset range, is selected.

[0060] Among them, the optical fiber sheath is the sheath of the optical fiber insulator, the optical fiber coating layer is an elastic coating layer cured by ultraviolet light on the surface of the optical fiber insulator to prevent dust contamination, the filler paste is the silicone oil-containing paste filled in the loose tube of the optical fiber insulator, the epoxy core rod is the optical fiber core of the optical fiber insulator, and finally, the maximum first electric field strength, the maximum second electric field strength, and the maximum third electric field strength are three sub-electric field information in the electric field information of the optical fiber insulator. The maximum first electric field strength is the maximum electric field strength at the interface between the optical fiber sheath and the optical fiber coating layer, the maximum second electric field strength is the maximum electric field strength at the interface between the filler paste and the optical fiber sheath, and the maximum third electric field strength is the maximum electric field strength at the interface between the epoxy core rod and the filler paste.

[0061] Specifically, from multiple sets of optical fiber insulator electric field information, the optical fiber insulator electric field information in which the maximum first electric field strength, the maximum second electric field strength, and the maximum third electric field strength are all within a preset range is selected as the target optical fiber insulator electric field information, and other data other than the target optical fiber insulator electric field information is discarded.

[0062] In this embodiment, by filtering out the target fiber optic insulator's electric field information from the electric field information of each fiber optic insulator, the target fiber optic insulator's electric field information can be accurately obtained, as the maximum first electric field strength, the maximum second electric field strength, and the maximum third electric field strength are all within a preset range.

[0063] In one embodiment, such as Figure 2 As shown, by determining the conductivity parameters of optical fiber insulator materials using a model, the electric field information of the optical fiber insulator corresponding to each material conductivity parameter is obtained, including the following steps:

[0064] Step S201: By determining the model through the conductivity parameters of the optical fiber insulator material, the first electric field intensity, the second electric field intensity, and the third electric field intensity corresponding to the conductivity parameters of each material are obtained respectively; the first electric field intensity is the electric field intensity at the interface between the optical fiber sheath and the optical fiber coating layer, the second electric field intensity is the electric field intensity at the interface between the optical fiber sheath and the filler paste, and the third electric field intensity is the electric field intensity at the interface between the filler paste and the epoxy core rod.

[0065] The first electric field intensity is the electric field intensity at the interface between the optical fiber sheath and the optical fiber coating layer, the second electric field intensity is the electric field intensity at the interface between the optical fiber sheath and the filler paste, and the third electric field intensity is the electric field intensity at the interface between the filler paste and the epoxy core rod.

[0066] Specifically, the voltage boundary conditions of the model are determined by the conductivity parameters of the fiber optic insulator material, and the operation of the fiber optic insulator is simulated. Based on the set conductivity parameters of each material, the first electric field strength, the second electric field strength and the third electric field strength corresponding to each material conductivity parameter are obtained.

[0067] Step S202: Obtain the maximum first electric field intensity among the first electric field intensities, the maximum second electric field intensity among the second electric field intensities, and the maximum first electric field intensity among the third electric field intensities.

[0068] Specifically, there are multiple first electric field strengths corresponding to each material conductivity parameter, and the maximum first electric field strength is selected from the multiple first electric field strengths. Then, there are multiple second electric field strengths corresponding to each material conductivity parameter, and the maximum second electric field strength is selected from the multiple second electric field strengths. Finally, there are multiple third electric field strengths corresponding to each material conductivity parameter, and the maximum third electric field strength is selected from the multiple third electric field strengths.

[0069] In this embodiment, by selecting the maximum first electric field strength from multiple first electric field strengths, the maximum second electric field strength from multiple second electric field strengths, and the maximum third electric field strength from multiple third electric field strengths, the electric field information of the optical fiber insulator corresponding to the conductivity parameters of each material can be accurately obtained.

[0070] In one embodiment, a model is used to determine the conductivity parameters of the optical fiber insulator material, and the first, second, and third electric field intensities corresponding to each material conductivity parameter are obtained, including the following steps:

[0071] By using the model for determining the conductivity parameters of optical fiber insulator materials, the initial first electric field strength, initial second electric field strength, and initial third electric field strength corresponding to each element in the model are obtained. Based on the initial first electric field strength, initial second electric field strength, and initial third electric field strength, the first electric field strength, second electric field strength, and third electric field strength corresponding to each material conductivity parameter are obtained.

[0072] In this model, each element represents a 3D model unit within the fiber optic insulator material conductivity parameter determination model. The initial first electric field strength is the first electric field strength corresponding to each element, the initial second electric field strength is the second electric field strength corresponding to each element, and the initial third electric field strength is the third electric field strength corresponding to each element.

[0073] Specifically, the voltage boundary conditions of the model are determined by the conductivity parameters of the fiber optic insulator material to simulate the operation of the fiber optic insulator. Based on the conductivity parameters of each material, the initial first electric field strength, initial second electric field strength, and initial third electric field strength corresponding to each unit in the model are obtained. Then, based on the initial first electric field strength, initial second electric field strength, and initial third electric field strength, the first electric field strength, second electric field strength, and third electric field strength corresponding to each material conductivity parameter are obtained.

[0074] In this embodiment, the initial first electric field strength, initial second electric field strength, and initial third electric field strength corresponding to each unit in the optical fiber insulator material conductivity parameter determination model are obtained through the model. Then, based on the initial first electric field strength, initial second electric field strength, and initial third electric field strength, the first electric field strength, second electric field strength, and third electric field strength corresponding to each material conductivity parameter are obtained. This allows for the accurate determination of the first electric field strength, second electric field strength, and third electric field strength corresponding to each material conductivity parameter.

[0075] In one embodiment, the target fiber optic insulator electric field information comprises one or more sub-electric field information; obtaining the maximum sub-electric field information among the multiple sub-electric field information contained in the target fiber optic insulator electric field information, and filtering out the final fiber optic insulator electric field information with the smallest maximum sub-electric field information from the target fiber optic insulator electric field information, includes the following steps:

[0076] Obtain the maximum value of the maximum first electric field strength, the maximum second electric field strength, and the maximum third electric field strength contained in the electric field information of each target optical fiber insulator; take the minimum maximum value among the maximum values ​​as the target optical fiber insulator electric field information, and use it as the final optical fiber insulator electric field information.

[0077] Among them, the maximum value is the maximum value among the maximum first electric field strength, the maximum second electric field strength, and the maximum third electric field strength, and the minimum maximum value is the minimum of the maximum values ​​corresponding to the electric field information of each target optical fiber insulator.

[0078] Specifically, for example, there are four sets of target fiber optic insulator electric field information: A, B, C, and D. The maximum first, second, and third electric field intensities for group A are A1, A2, and A3, respectively; for group B, they are B1, B2, and B3; for group C, they are C1, C2, and C3; and for group D, they are D1, D2, and D3. If a comparison shows that max{A1, A2, A3} > max{B1, B2, B3} > max{C1, C2, C3} > max{D1, D2, D3}, then the target fiber optic insulator electric field information for group D is taken as the final fiber optic insulator electric field information.

[0079] In this embodiment, by obtaining the maximum values ​​of the maximum first electric field strength, the maximum second electric field strength, and the maximum third electric field strength contained in the electric field information of each target optical fiber insulator, and taking the minimum maximum value among the maximum values ​​as the target optical fiber insulator electric field information, the final optical fiber insulator electric field information can be accurately confirmed.

[0080] In one embodiment, such as Figure 3 As shown, before obtaining multiple pre-set material conductivity parameters for the fiber optic insulator, the following steps are also included:

[0081] Step S301: Based on the pre-obtained basic properties of the optical fiber insulator, construct a three-dimensional geometric model of the optical fiber insulator.

[0082] Among them, the basic properties are the basic material properties and basic physical properties of the optical fiber insulator, while the three-dimensional geometric model is a three-dimensional geometric model of the optical fiber insulator constructed using COMSOL.

[0083] Specifically, the basic properties of the fiber optic insulator obtained in advance are input into the COMSOL platform to construct a three-dimensional geometric model of the fiber optic insulator.

[0084] Step S302: In the three-dimensional geometric model, set the voltage boundary conditions for the optical fiber insulator; the voltage boundary conditions are used to characterize the voltage applied to the optical fiber insulator.

[0085] The voltage boundary condition is the voltage applied to the fiber optic insulator. For example, the high-voltage flange of the fiber optic insulator is set to 400kV, and the low-voltage flange is set to ground.

[0086] Specifically, in the three-dimensional geometric model, the voltage applied to the fiber optic insulator when it is in operation is set.

[0087] Step S303: Divide the three-dimensional geometric model with voltage boundary conditions set into multiple elements to obtain the model for determining the conductivity parameters of the optical fiber insulator material.

[0088] Specifically, the three-dimensional geometric model with voltage boundary conditions set is divided into multiple mesh elements to obtain a model for determining the conductivity parameters of the fiber optic insulator material.

[0089] In this embodiment, by inputting the basic properties of the fiber optic insulator obtained in advance into the COMSOL platform, a three-dimensional geometric model of the fiber optic insulator is constructed. Then, the voltage boundary conditions of the fiber optic insulator are set. Finally, the three-dimensional geometric model with the voltage boundary conditions set is divided into multiple units to obtain a model for determining the conductivity parameters of the fiber optic insulator material. This model can accurately determine the conductivity parameters of the fiber optic insulator material.

[0090] In one application embodiment, such as Figure 4 As shown, a method for optimizing the material property parameters of optical fiber insulators based on COMSOL is provided, which specifically includes the following steps:

[0091] S1. Create a three-dimensional geometric model of the optical fiber insulator in COMSOL software.

[0092] S2. Set the voltage boundary conditions for the fiber optic insulator: set the high-voltage flange to 400kV and the low-voltage flange to ground.

[0093] S3. Divide the geometric model of the optical fiber insulator into several grid units, with the grid shape being a free tetrahedron.

[0094] S4. Set the material property parameters for each part of the optical fiber insulator structure. The material property parameters of the optical fiber insulator include the conductivity of the optical fiber sheath and the conductivity of the filler paste.

[0096] S6. Adjust the material property parameters of the optical fiber insulator and return to step S5. The conductivity value of the optical fiber sheath is within the range of existing optical fiber sheath products made of materials such as ethylene-tetrafluoroethylene copolymer (ETFE) and low smoke halogen-free (LSZH). The conductivity value of the filler paste is within the range of existing filler media such as multi-component filler paste containing silicone oil, polyisobutylene, and two-component adhesive.

[0097] S7. Determine whether the number of times the material property parameters of the optical fiber insulator have been adjusted has reached the set value. If so, proceed to step S8.

[0098] S8. The material property parameters of the optical fiber insulator corresponding to the optimal electric field distribution index are selected as the optimal parameters through multiple calculations. The electric field distribution index includes the maximum electric field strength at the interface between the optical fiber sheath and the optical fiber coating, the maximum electric field strength at the interface between the filler paste and the optical fiber sheath, and the maximum electric field strength at the interface between the epoxy core rod and the filler paste. Specifically, determining the optimal electric field index includes:

[0099] S81. Select the simulation process where the maximum electric field strength at the interface between the fiber sheath and the fiber coating is within the set threshold range, and proceed to step S82.

[0100] S82. In the simulation process that satisfies S81, select the simulation process where the maximum electric field intensity at the interface between the filler paste and the optical fiber sheath is within the set threshold range, and proceed to step S83.

[0101] S83. In the simulation process that satisfies S82, select the simulation process where the maximum electric field intensity at the interface between the epoxy core rod and the filler paste is within the set threshold range, and proceed to step S84.

[0102] S84. In the simulation process that satisfies S83, the material property parameters corresponding to the simulation process with the smallest maximum value among the three maximum electric field intensities are selected as the optimal parameters.

[0103] In this embodiment, if the current simulation process cannot satisfy the requirement that the three maximum electric field intensities are simultaneously within the set threshold range, the screening process is as follows: expand the range of values ​​for the conductivity of the fiber sheath and the conductivity of the filler paste until a simulation process that meets the conditions appears.

[0104] In the simulation process satisfying S83, the material property parameters corresponding to the simulation process with the smallest maximum value among the maximum electric field strength at the interface between the fiber sheath and the fiber coating, the interface between the filler paste and the fiber sheath, and the interface between the epoxy core and the filler paste are selected as the optimal parameters. For example, there are four sets of material property parameters A, B, C, and D that satisfy S83. The three maximum electric field strengths corresponding to the three locations in set A are A1, A2, and A3, respectively; those in set B are B1, B2, and B3, respectively; those in set C are C1, C2, and C3, respectively; and those in set D are D1, D2, and D3, respectively. If the comparison shows that max{A1, A2, A3} > max{B1, B2, B3} > max{C1, C2, C3} > max{D1, D2, D3}, then the data in set D are selected as the optimal material property parameters for the fiber optic insulator.
