Description

Technical Field

[0001] The present application relates to the technical field of electrical design, and particularly to a simulation method, device, computer equipment, storage medium and computer program product for cable laying in a nuclear power plant. Background Art

[0002] Cable laying refers to the process of laying and installing cables along a surveyed route to form a cable line. With the development of nuclear power technology, since cables are needed to transmit signals in a nuclear power plant, cable laying has become a crucial part of a nuclear power plant.

[0003] In traditional technologies, cable laying is mainly designed through cable simulation software. The specific process is as follows: System designers write out the cable inventory information item by item and send it to cable simulation personnel. The cable simulation personnel enter the cable inventory information into the cable simulation software to complete the simulation, and send the obtained simulation length to the system designers. The system designers calculate the voltage drop based on the cable length. If it does not meet the requirements, they correct the cable model, etc., and feedback it to the cable simulation personnel for iterative design. In this process, several information exchanges and data processing are required, and due to human factors, the accuracy of information may decrease during multiple information exchanges and data processing. Therefore, the simulation results of the current cable laying simulation method in a nuclear power plant are inaccurate and cannot effectively support the cable laying construction in a nuclear power plant.

[0065] In order to make the objectives, technical solutions and advantages of the present application more clear and understandable, the present application will be further described in detail below with reference to 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.

[0066] The nuclear power plant cable laying simulation method provided by the embodiment of the present application can be applied to an application environment as Figure 1 shown. Among them, the two-dimensional electrical design system 102 communicates with the three-dimensional layout simulation system 104 through a network. The data storage system can store the data that the three-dimensional layout simulation system 104 needs to process. The data storage system can be integrated on the three-dimensional layout simulation system 104, or placed in the cloud or other network servers. First, after the two-dimensional electrical design system 102 designs the cable schedule, it generates cable schedule information, and sends a nuclear power plant cable laying simulation request and the cable schedule information to the three-dimensional layout simulation system 104. The nuclear power plant cable laying simulation request carries simulation area environmental temperature information, nuclear radiation zoning information and disaster zoning information; the three-dimensional layout simulation system 104 receives the nuclear power plant cable laying simulation request and the cable schedule information; extracts the simulation area environmental temperature information, nuclear radiation zoning information and disaster zoning information carried by the nuclear power plant cable laying simulation request, and establishes a three-dimensional plant model according to the extracted information; based on the cable schedule information and the three-dimensional plant model, conducts cable laying simulation to obtain cable laying simulation results; checks whether the cable laying simulation results are abnormal according to the simulation area environmental temperature information, nuclear radiation zoning information and disaster zoning information. If abnormal, obtains the abnormal influencing factors corresponding to the abnormal verification results; the three-dimensional layout simulation system 104 feeds back the abnormal influencing factors to the two-dimensional electrical design system 102, and receives the corrected cable schedule information, and returns to the step of conducting cable laying simulation based on the cable schedule information and the three-dimensional plant model to obtain cable laying simulation results. The abnormal influencing factors are used to correct the cable schedule information of the two-dimensional electrical design system to obtain the corrected cable schedule information.

[0067] In one embodiment, as Figure 2 shown, a nuclear power plant cable laying simulation method is provided. Taking the method applied to the three-dimensional layout simulation system 104 in Figure 1 as an example, the method includes the following steps:

[0068] S100, receiving a nuclear power plant cable laying simulation request and cable schedule information, where the cable schedule information is generated after the two-dimensional electrical design system designs the cable schedule.

[0069] Among them, cable laying simulation refers to the simulation model technology that reflects the cable laying process in a three-dimensional layout simulation system; a register is a booklet that details relevant items; in this application, the cable register information is the basis for cable laying and guiding construction, and is the archival material for operation and maintenance.

[0070] Specifically, the two-dimensional electrical design system communicates with the three-dimensional layout simulation system through a network; after the two-dimensional electrical design system designs the cable register, it generates cable register information and sends a nuclear power plant cable laying simulation request, as well as the cable register information, to the three-dimensional layout simulation system. The nuclear power plant cable laying simulation request carries simulation area environmental temperature information, nuclear radiation zoning information, and disaster zoning information; the three-dimensional layout simulation system receives the nuclear power plant cable laying simulation request and the cable register information.

[0071] Furthermore, the means by which the two-dimensional electrical design system sends the nuclear power plant cable laying simulation request and the cable register information to the three-dimensional layout simulation system can be through an interface or by changing the file path to send it to the three-dimensional layout simulation system; the cable register information should include: cable number, cable characteristic code, identification grade, column / group, safety grade, color, voltage grade, starting equipment, starting room number, ending equipment, ending room, etc. information. Among them, the cable number is the identifier for identifying the cable, with uniqueness and regularity; the cable characteristic code is the character that characterizes the cable specifications.

[0072] S200, extract the simulation area environmental temperature information, nuclear radiation zoning information, and disaster zoning information carried by the nuclear power plant cable laying simulation request, and establish a three-dimensional plant model based on the extracted information.

[0073] Among them, the three-dimensional plant model refers to a three-dimensional model that is simulated in a three-dimensional layout simulation system based on the actual plant model and carries information such as simulation area environmental temperature information, nuclear radiation zoning information, and disaster zoning information.

[0074] Specifically, the three-dimensional layout simulation system receives the nuclear power plant cable laying simulation request, and extracts the simulation area environmental temperature information, nuclear radiation zoning information, and disaster zoning information carried by the nuclear power plant cable laying simulation request. The nuclear radiation zoning information and the disaster zoning information respectively contain the zoning criteria for nuclear radiation and disasters, which are used to partition the model to establish a three-dimensional plant model. Therefore, the established three-dimensional plant model carries information such as simulation area environmental temperature information, nuclear radiation zoning information, and disaster zoning information.

[0075] S300, based on the cable register information and the three-dimensional plant model, conduct cable laying simulation to obtain the cable laying simulation result.

[0076] Specifically, based on the cable list information, the 3D layout simulation system can automatically perform cable laying simulation in the 3D plant model to obtain the cable laying simulation results after the cable laying simulation.

[0077] S400. Check whether the cable laying simulation results are abnormal according to the environmental temperature information, nuclear radiation zoning information, and disaster zoning information of the simulation area. If abnormal, obtain the abnormal influencing factors corresponding to the abnormal verification results.

[0078] Specifically, the cable laying simulation results automatically performed based on the initial cable list information are not necessarily correct. There may be situations where it cannot adapt to various harmful environments or the voltage drop does not meet the cable requirements. Therefore, the 3D layout simulation system can check the cable laying simulation results according to the environmental temperature information, nuclear radiation zoning information, and disaster zoning information of the simulation area to determine whether the cable laying simulation results are abnormal. If the cable laying simulation results are abnormal according to the environmental temperature information, nuclear radiation zoning information, and disaster zoning information of the simulation area, then determine which factor caused the abnormal results and obtain the abnormal influencing factors corresponding to the abnormal verification results.

[0079] S500. Feed back the abnormal influencing factors to the 2D electrical design system, receive the corrected cable list information, and return to the step of performing cable laying simulation based on the cable list information and the 3D plant model to obtain the cable laying simulation results. The abnormal influencing factors are used to correct the cable list information in the 2D electrical design system to obtain the corrected cable list information.

[0080] Specifically, since the cable laying results are generated based on the cable list information sent by the 2D electrical design system, in order to obtain cable laying results that meet the requirements, the 3D layout simulation system will feed back the abnormal influencing factors corresponding to the abnormal verification results to the 2D electrical design system to correct the cable list information generated in the 2D electrical design system, that is, re-design the cable list for the abnormal influencing factors to obtain the corrected cable list information. The 3D layout simulation system receives the corrected cable list information and returns to the step of performing cable laying simulation based on the cable list information and the 3D plant model to obtain the cable laying simulation results until the generated cable laying simulation results do not meet the situation where the cable laying simulation results are abnormal according to the environmental temperature information, nuclear radiation zoning information, and disaster zoning information of the simulation area. That is, after the cable laying simulation results are normal according to the environmental temperature information, nuclear radiation zoning information, and disaster zoning information of the simulation area, the latest cable laying simulation results are the finally generated cable laying simulation model.

[0081] In the above nuclear power plant cable laying simulation method, a nuclear power plant cable laying simulation request and cable schedule information are received. The cable schedule information is generated after the cable schedule is designed by a two-dimensional electrical design system; the simulation area environmental temperature information, nuclear radiation zoning information, and disaster zoning information carried in the nuclear power plant cable laying simulation request are extracted, and a three-dimensional plant model is established based on the extracted information; based on the cable schedule information and the three-dimensional plant model, cable laying simulation is performed to obtain a cable laying simulation result; whether the cable laying simulation result is abnormal is verified according to the simulation area environmental temperature information, nuclear radiation zoning information, and disaster zoning information. If it is abnormal, the abnormal influencing factors corresponding to the verification result are obtained; the abnormal influencing factors are fed back to the two-dimensional electrical design system, and the corrected cable schedule information is received, and the step of performing cable laying simulation based on the cable schedule information and the three-dimensional plant model to obtain a cable laying simulation result is returned. The abnormal influencing factors are used to correct the cable schedule information of the two-dimensional electrical design system to obtain the corrected cable schedule information. In this process, on the one hand, based on the interaction with the two-dimensional electrical design system, the influence of human factors on the accuracy of cable laying simulation is removed; on the other hand, the cable information is verified from multiple dimensions related to nuclear radiation and disasters, and the verification result is fed back to correct the cable schedule information of the two-dimensional electrical design system, and a more accurate cable laying simulation result can be obtained.

[0082] In one embodiment, as Figure 3 shown, S200 includes:

[0083] S220, obtain an initial three-dimensional plant model.

[0084] Specifically, to obtain an initial three-dimensional plant model, the initial three-dimensional plant model refers to a three-dimensional model simulated in a three-dimensional layout simulation system based on a real plant model, which does not carry simulation area environmental temperature information, nuclear radiation zoning information, and disaster zoning information.

[0085] S240, extract the simulation area environmental temperature information, nuclear radiation zoning information, and disaster zoning information carried in the nuclear power plant cable laying simulation request.

[0086] Specifically, the three-dimensional layout simulation system receives the nuclear power plant cable laying simulation request and extracts the simulation area environmental temperature information, nuclear radiation zoning information, and disaster zoning information carried in the nuclear power plant cable laying simulation request. Among them, the simulation area temperature information can be the temperature information in each room where cables need to be laid; both the nuclear radiation zoning information and the disaster zoning information include the nuclear radiation information and disaster information in the initial three-dimensional plant model, and provide a zoning basis for zoning the initial three-dimensional plant model according to the nuclear radiation information and disaster information.

[0087] S260. According to the nuclear radiation zoning information and the disaster zoning information, perform nuclear radiation zoning and disaster zoning on the initial 3D plant model to obtain the nuclear radiation levels corresponding to each area after nuclear radiation zoning and the disaster types corresponding to each area after disaster zoning in the initial 3D plant model.

[0088] Specifically, according to the nuclear radiation zoning information, the initial 3D plant model can be zoned for nuclear radiation. Areas with similar nuclear radiation in the initial 3D plant model are grouped into one area. The nuclear radiation levels corresponding to each area can be the red zone, the orange zone, and the yellow zone. Among the red zone, the orange zone, and the yellow zone, the nuclear radiation levels decrease in sequence, with the red zone having the highest nuclear radiation level and the yellow zone having the lowest nuclear radiation level. Similarly, according to the disaster zoning information, the initial 3D plant model can be zoned for disaster information. Areas with similar disaster types in the initial 3D plant model are grouped into one area. The disaster types corresponding to each area can be the fire risk area, the flood risk area, etc. Generally speaking, according to the nuclear radiation zoning information and the disaster zoning information, performing nuclear radiation zoning and disaster zoning on the initial 3D plant model can obtain the nuclear radiation levels corresponding to each area after nuclear radiation zoning and the disaster types corresponding to each area after disaster zoning in the initial 3D plant model.

[0089] S280. Establish a 3D plant model according to the simulated area environmental temperature information, the nuclear radiation levels corresponding to each area after nuclear radiation zoning, and the disaster types corresponding to each area after disaster zoning.

[0090] Specifically, according to the simulated area environmental temperature information, the nuclear radiation levels corresponding to each area after nuclear radiation zoning, and the disaster types corresponding to each area after disaster zoning, the temperature information, nuclear radiation level, and disaster type of each room in the initial 3D plant model that needs to perform cable laying simulation can be known, thereby establishing a 3D plant model carrying information such as the simulated area environmental temperature information, nuclear radiation zoning information, and disaster zoning information.

[0091] In this embodiment, by extracting the simulated area environmental temperature information, nuclear radiation zoning information, and disaster zoning information carried in the cable laying simulation request of the nuclear power plant, performing nuclear radiation zoning and disaster zoning on the initial 3D plant model, the temperature information, nuclear radiation level, and disaster type of each room in the initial 3D plant model that needs to perform cable laying simulation can be obtained, laying a foundation for accurately verifying the cable laying simulation results subsequently.

[0092] In one embodiment, based on the cable schedule information and the 3D plant model, perform cable laying simulation, and the obtained cable laying simulation results include:

[0093] Obtain the electrical equipment layout information for nuclear power plant cable laying simulation and the cable tray layout information for nuclear power plant cable laying simulation; based on the electrical equipment layout information, cable tray layout information, cable list information, and three-dimensional plant model, conduct cable laying simulation to obtain the cable laying simulation results.

[0094] Among them, the electrical equipment layout information refers to the layout information of electrical equipment preset in the three-dimensional plant model; a cable tray refers to a rigid structure system composed of straight sections, elbows, tees, crosses of trough type, tray type or ladder type, as well as brackets (arm type supports), hangers, etc., which closely support cables; the cable tray layout information refers to the layout information of the cable tray preset in the three-dimensional plant model.

[0095] Specifically, obtain the layout information of electrical equipment preset in the three-dimensional plant model and the layout information of cable trays preset in the three-dimensional plant model during nuclear power plant cable laying simulation; based on the electrical equipment layout information, cable tray layout information, cable list information, and three-dimensional plant model, conduct cable laying simulation, and the layout of electrical equipment, cable trays, and cables in the three-dimensional plant model can be simulated to obtain the cable laying simulation results. Among them, cables can be used to connect electrical equipment to electrical equipment, electrical equipment to cable trays, and cable trays to cable trays.

[0096] In this embodiment, by obtaining the electrical equipment layout information for nuclear power plant cable laying simulation and the cable tray layout information for nuclear power plant cable laying simulation, cable laying simulation can be carried out more comprehensively to obtain the cable laying simulation results.

[0097] In one embodiment, as Figure 4 shown, S400 includes:

[0098] S420, according to the cable laying simulation results, obtain the cable laying simulation length.

[0099] Specifically, according to the cable laying simulation results, the three-dimensional layout simulation system can automatically obtain the cable laying simulation length.

[0100] S440, according to the nuclear radiation zoning information and disaster zoning information, obtain the nuclear radiation levels corresponding to each area after nuclear radiation zoning and the disaster types corresponding to each area after disaster zoning.

[0101] Specifically, since the 3D plant model is established based on the environmental temperature information of the simulation area, the nuclear radiation levels corresponding to each area after nuclear radiation zoning, and the types of disasters corresponding to each area after disaster zoning, the 3D plant model carries information such as the environmental temperature information of the simulation area, nuclear radiation zoning information, and disaster zoning information. Based on the nuclear radiation zoning information and disaster zoning information in the 3D plant model, the nuclear radiation levels corresponding to each area after nuclear radiation zoning and the types of disasters corresponding to each area after disaster zoning can be obtained.

[0102] S460. Check whether the cable laying simulation result is abnormal according to the cable laying simulation length, the environmental temperature information of the simulation area, the nuclear radiation levels corresponding to each area after nuclear radiation zoning, and the types of disasters corresponding to each area after disaster zoning. If it is abnormal, obtain the abnormal influencing factors corresponding to the abnormal check result.

[0103] Specifically, if the cable laying simulation result is checked according to the cable laying simulation length, the environmental temperature information of the simulation area, the nuclear radiation levels corresponding to each area after nuclear radiation zoning, and the types of disasters corresponding to each area after disaster zoning, determine whether the cable laying simulation result is abnormal. If the check result is abnormal, determine which factor causes the abnormal result and obtain the abnormal influencing factors corresponding to the abnormal check result.

[0104] In this embodiment, by performing multi-dimensional checks on the cable laying simulation result according to the cable laying simulation length, the environmental temperature information of the simulation area, the nuclear radiation levels corresponding to each area after nuclear radiation zoning, and the types of disasters corresponding to each area after disaster zoning, an accurate cable laying simulation check result can be obtained. When the check result is abnormal, the abnormal influencing factors corresponding to the abnormal check result can be obtained, which serves as a basis for subsequently correcting the abnormal influencing factors to obtain a more accurate cable laying result.

[0105] In one embodiment, checking whether the cable laying simulation result is abnormal according to the cable laying simulation length, the environmental temperature information of the simulation area, the nuclear radiation levels corresponding to each area after nuclear radiation zoning, and the types of disasters corresponding to each area after disaster zoning, and if it is abnormal, obtaining the abnormal influencing factors corresponding to the abnormal check result includes:

[0106] Obtain the preset cable voltage drop, the cable qualification level corresponding to the preset nuclear radiation level, and the cable model corresponding to the preset disaster type.

[0109] According to the cable laying simulation length, the environmental temperature information of the simulation area, and the preset cable voltage drop, check whether the cable voltage drop in the cable laying simulation result is abnormal. If it is abnormal, obtain the abnormal influencing factors corresponding to the abnormal cable voltage drop.

[0110] Specifically, according to the cable laying simulation length, the environmental temperature information of the simulation area, and the preset cable voltage drop, the cable voltage drop in the cable laying simulation result can be checked. Determine whether the cable voltage drop in the cable laying simulation result calculated according to the cable laying simulation length and the environmental temperature information of the simulation area meets the requirements of the preset cable voltage drop, that is, check whether the cable voltage drop in the cable laying simulation result is abnormal. If it does not meet the requirements, it is determined that the cable voltage drop is abnormal, analyze which factor causes the abnormal cable voltage drop, and obtain the abnormal influencing factors corresponding to the abnormal cable voltage drop.

[0111] According to the nuclear radiation level corresponding to each area after nuclear radiation zoning and the cable identification level corresponding to the preset nuclear radiation level, check whether the radiation protection ability of the cable in the cable laying simulation result is abnormal. If it is abnormal, obtain the abnormal influencing factors corresponding to the abnormal radiation protection ability of the cable.

[0112] Specifically, according to the nuclear radiation level corresponding to each area after nuclear radiation zoning and the cable identification level corresponding to the preset nuclear radiation level, the radiation protection ability of the cable in the cable laying simulation result can be checked. Determine whether the cable identification level corresponding to the nuclear radiation level in the area where each room where the cable needs to be laid in the cable laying simulation result meets the requirements of the cable identification level corresponding to the preset nuclear radiation level, that is, check whether the radiation protection ability of the cable in the cable laying simulation result is abnormal according to the nuclear radiation level corresponding to each area after nuclear radiation zoning and the cable identification level corresponding to the preset nuclear radiation level. If it does not meet the requirements of the cable identification level corresponding to the preset nuclear radiation level, it is considered that the radiation protection ability of the cable in the cable laying simulation result is abnormal, and obtain the abnormal influencing factors corresponding to the abnormal radiation protection ability of the cable.

[0113] Furthermore, taking the nuclear radiation levels corresponding to each area after nuclear radiation zoning as the red zone, orange zone, and yellow zone as examples, the preset cable identification level corresponding to the red zone is K1, the preset cable identification level corresponding to the orange zone is K2, and the preset cable identification level corresponding to the yellow zone is K3; if cable laying simulation is required in a room in the red zone, the cable identification level in the obtained cable laying simulation result must be K1; otherwise, it is considered that the cable identification level requirements corresponding to the preset nuclear radiation level are not met, and the abnormal influencing factors corresponding to the abnormal anti-radiation ability of the cable need to be obtained.

[0114] According to the types of disasters corresponding to each area after disaster zoning and the cable models corresponding to the preset disaster types, check whether the disaster prevention ability of the cables in the cable laying simulation result is abnormal. If it is abnormal, obtain the abnormal influencing factors corresponding to the abnormal disaster prevention ability of the cables.

[0115] Specifically, according to the types of disasters corresponding to each area after disaster zoning and the cable models corresponding to the preset disaster types, the disaster prevention ability of the cables in the cable laying simulation result can be checked. Determine whether the cable models corresponding to the types of disasters in the area where each cable to be laid in the cable laying simulation result is located meet the requirements of the cable models corresponding to the preset disaster types, that is, check whether the disaster prevention ability of the cables in the cable laying simulation result is abnormal according to the types of disasters corresponding to each area after disaster zoning and the cable models corresponding to the preset disaster types. If the requirements of the cable models corresponding to the preset disaster types are not met, it is considered that the disaster prevention ability of the cables in the cable laying simulation result is abnormal, and the abnormal influencing factors corresponding to the abnormal disaster prevention ability of the cables are obtained.

[0116] Furthermore, taking the types of disasters corresponding to each area after disaster zoning as the fire risk area as an example, the preset cable model corresponding to the fire risk area is flame-retardant or fire-resistant cable; if cable laying simulation is required in a room in the fire risk area, the cable model in the obtained cable laying simulation result must be flame-retardant or fire-resistant cable; otherwise, to check the abnormal disaster prevention ability of the cables in the cable laying simulation result, obtain the abnormal influencing factors corresponding to the abnormal disaster prevention ability of the cables.

[0117] Collect the abnormal influencing factors corresponding to the abnormal cable voltage drop, the abnormal influencing factors corresponding to the abnormal anti-radiation ability of the cable, and the abnormal influencing factors corresponding to the abnormal disaster prevention ability of the cable, and obtain the abnormal influencing factors corresponding to the abnormal verification result.

[0118] Specifically, by comprehensively considering the abnormal influencing factors corresponding to the abnormal cable voltage drop, the abnormal influencing factors corresponding to the abnormal anti-radiation ability of the cable, and the abnormal influencing factors corresponding to the abnormal disaster prevention ability of the cable, the abnormal influencing factors corresponding to the abnormal verification result can be obtained.

[0119] In this embodiment, by performing multi-dimensional verification on the cable voltage drop, cable anti-radiation ability, and cable disaster prevention ability in the cable laying simulation results, more accurate verification results can be obtained; when the verification results are abnormal, the abnormal influencing factors corresponding to the abnormal verification results will be caused, which serves as a basis for subsequently correcting the abnormal influencing factors to obtain more accurate cable laying results.

[0120] In one embodiment, according to the cable laying simulation length, the simulation area ambient temperature information, and a preset cable voltage drop, verify whether the cable voltage drop in the cable laying simulation result is abnormal. If it is abnormal, the abnormal influencing factors corresponding to the abnormal cable voltage drop are obtained, including:

[0121] Obtain the cable laying simulation cross-section information and the cable laying simulation current information; according to the cable laying simulation cross-section information, the simulation area ambient temperature information, and the cable laying simulation length, obtain the corresponding cable laying simulation resistance.

[0122] Among them, in solid geometry, a cross-section refers to a plane figure obtained by cutting a geometric body with a plane; the cable laying simulation cross-section refers to a plane obtained by cutting a cable with a plane; the cable laying simulation current information refers to the current of the cable in the cable laying simulation result.

According to the cable laying simulation cross-section information, the area S of the cable laying simulation cross-section can be obtained, and according to the cable laying simulation current information, the cable laying simulation current I can be obtained; since the simulation area ambient temperature information is related to the resistivity of the cable laying simulation, and the calculation formula of the cable laying simulation resistance R is R = ρ × L / S, where ρ is the cable laying simulation resistivity, L is the cable laying simulation length, and S is the area of the cable laying simulation cross-section; therefore, the corresponding cable laying simulation resistance can be obtained according to the area S of the cable laying simulation cross-section, the simulation area ambient temperature information, and the cable laying simulation length L.

[0124] Obtain the cable voltage drop according to the cable laying simulation resistance and the cable laying simulation current information.

[0125] Specifically, to calculate the cable voltage drop ΔU = I × R, it is necessary to calculate according to the cable laying simulation resistance R and the cable laying simulation current information to obtain the cable laying simulation current I for calculation, so as to obtain the cable voltage drop.

[0126] According to the preset cable voltage drop, verify whether the cable voltage drop in the cable laying simulation result is abnormal. If it is abnormal, obtain the abnormal influencing factors corresponding to the abnormal cable voltage drop.

[0127] Specifically, if the cable voltage drop obtained based on the cable laying simulation resistance and the cable laying simulation current information does not meet the requirements of the preset cable voltage drop, it can be considered that the cable voltage drop in the cable laying simulation result is abnormal, and an analysis can be carried out on which factor causes the abnormal cable voltage drop, and the abnormal influencing factor corresponding to the abnormal cable voltage drop can be obtained. Among them, the abnormal influencing factor can be the cable laying simulation cross-section information, the cable laying simulation length, etc.

[0128] In this embodiment, by obtaining the cable laying simulation cross-section information and the cable laying simulation current information, the voltage drop of the cable in the cable laying simulation result can be accurately calculated to obtain an accurate cable voltage drop verification result.

If the cable voltage drop in the cable laying simulation result is normal according to the preset cable voltage drop, directly proceed to step 7; if the cable voltage drop in the cable laying simulation result is abnormal according to the preset cable voltage drop, then obtain the abnormal influencing factors corresponding to the abnormal cable voltage drop, and then proceed to step 7.
