[0002] Power transmission and transformation projects refer to the construction of power transmission lines and transformer installation projects. In recent years, 3D design has been widely used in power transmission and transformation projects, which has greatly improved the efficiency and quality of power transmission and transformation projects. The use of 3D design can effectively improve the scientificity and rationality of engineering design. With the continuous acceleration of social and economic development, the demand for electricity in various industries has continued to increase, which has enabled the construction of power transmission and transformation stations to achieve leapfrog development. Relevant units have increased the cost of using 3D design when carrying out power transmission and transformation projects.

[0003] However, the use of three-dimensional design for power transmission and transformation projects is not yet mature and there are some problems: First, although power transmission and transformation projects have transitioned from two-dimensional design to three-dimensional design, they still need to be designed on a blank platform. The existing technology cannot realize the collaborative sharing function of power transmission and transformation project design. When users need to complete the project within a certain period of time, the design efficiency cannot be improved; secondly, some power transmission and transformation project designs have compatible properties, and it is impossible to select appropriate power transmission and transformation project models through evaluation projects as the basic models for other engineering designs to effectively reduce modeling time and modeling costs during design.

[0004] Therefore, people need a power transmission and transformation project evaluation system and method based on three-dimensional design to solve the above problems. Summary of the invention

[0014] Furthermore, the engineering evaluation module includes an evaluation model generation unit and an engineering applicability evaluation unit. The evaluation model generation unit is used to establish an evaluation function for a power transmission and transformation project based on three-dimensional design in combination with the modification workload and the degree of compatibility. The engineering applicability evaluation unit is used to substitute different user demand data into the evaluation function, and the applicability of the power transmission and transformation project as a basic model for the corresponding user to design other power transmission and transformation projects is evaluated. The most suitable basic model for the power transmission and transformation project is selected for the user, and the user designs the power transmission and transformation project by modifying the selected basic model.

[0016] A power transmission and transformation project evaluation method based on three-dimensional design, characterized in that it includes the following steps:

[0017] S01: Collect user demand data and design data of power transmission and transformation projects on the 3D design platform;

[0018] S02: After generating the 3D engineering model, generate a joint modification path and predict the workload required for modifying the corresponding points of the model;

[0019] S03: Analyze the compatibility of the designed power transmission and transformation projects;

[0020] S04: Establish an evaluation function for power transmission and transformation engineering, substitute user demand data, and evaluate the applicability of the power transmission and transformation engineering model as a basic model;

[0021] S05: Update and substitute demand data in real time to evaluate the project.

[0022] Further, in step S01-S02: the set of power transmission and transformation project design completion time required by the user is collected as ,in, represents the number of power transmission and transformation projects, collects the design difference points of two random power transmission and transformation projects, and the influence coefficient set of the difference points on the project construction is ,in, represents the number of design differences between two power transmission and transformation projects. If a random difference point is modified in one of the power transmission and transformation projects, the points that need to be modified in sequence are obtained. The time required to modify the points that need to be modified in sequence is collected as follows: , the influence coefficient set of the joint modification point on the engineering construction is , establish a two-dimensional coordinate system, and generate the set of point coordinates that need to be modified: ,in, Indicates the number of points that need to be modified when modifying a random difference point.

Often, a modification in one place will affect the design of other places. By comparing the difference points of the power transmission and transformation engineering design two by two, the point data that needs to be modified synchronously due to the modification of the difference points is analyzed. The degree of influence of the modification points on the entire engineering design is added based on the time required for the modification, and the coordinates of the modification points are generated. The purpose of analyzing the workload by calculating the area formed by the modification path and the coordinate system is to predict the comprehensive impact of the modification of the corresponding power transmission and transformation engineering model. The greater the modification workload, the less suitable it is as a basic engineering model for users to modify the design.

[0025] Further, in step S03: two random images of power transmission and transformation engineering drawings are collected, and the means of the two images are calculated using the Gaussian function to be: A1 and A2, the variances are B1 and B2, and the covariance is C 12 , calculate the compatibility degree Si of one power transmission and transformation project relative to the design of another power transmission and transformation project according to the following formula:

The higher the compatibility degree, the more suitable the corresponding engineering model is as the basic model, which is helpful to reduce the user’s modification work on the model and save engineering design time.

Combined with the project compatibility and modification workload, the power transmission and transformation project evaluation function is established, and the project design time is used as the dependent variable. The user substitutes different required design times to obtain the evaluation scores of different power transmission and transformation projects. The higher the evaluation score, the more the corresponding power transmission and transformation project model is selected as the basic model for the user to use. The shorter the time it takes for the user to complete the project design, which improves the efficiency of the user in designing power transmission and transformation projects.

[0029] Compared with the prior art, the beneficial effects achieved by the present invention are:

The greater the modification workload, the less suitable it is as a basic engineering model for users to modify the design. An evaluation function is set in combination with the engineering modification amount and the compatibility degree to evaluate the project, and the most suitable engineering model is selected as the basic model. By modifying the basic model, the user effectively reduces the modeling time and modeling cost required for the design, thereby improving the efficiency of engineering design.
