Description

Technical Field

[0001] The invention belongs to the technical field of digital design of electrical systems, and in particular relates to a method for arranging pumped storage electrical equipment. Background Art

[0002] The concept of pumped-storage power stations was proposed more than a hundred years ago, and they are mainly used for peak load regulation and frequency regulation of power grids. As the power grid continues to expand, the contradiction between peak load regulation and valley load regulation has become increasingly prominent. As the most reliable and economical energy storage device under the current technical level, pumped-storage power stations have been vigorously developed in conjunction with new energy power. However, the current digital design of the water conservancy and hydropower industry is relatively lagging behind the entire market. The results of digitalization are often only reflected in the display of effects and cannot adapt to the digital construction of the entire life cycle. The establishment of its effect model is also achieved by professional modelers through "re-modeling" after the construction is completed on the basis of traditional design, which invisibly increases the workload and affects the efficiency of the entire industry. At the same time, it also violates the original intention of digital construction.

[0003] For a long time, the main reasons hindering the digital development of the pumped storage design industry are: 1. The existing equipment models do not have full life cycle attributes and cannot guarantee better design inheritance; 2. The existing models, drawings, etc. have low reusability, and each project needs to be redrawn. When changes occur, they need to be redesigned, affecting work efficiency. Summary of the invention

[0004] The purpose of the present invention is to provide a method for arranging pumped storage electrical equipment, which solves the problem that existing models, drawings, etc. in the prior art have low reusability, each project needs to be redrawn, and when changes occur, they need to be redesigned.

[0005] The technical solution adopted by the present invention is a method for arranging pumped storage electrical equipment, comprising the following steps: Step 1: Create an electrical equipment model library for a pumped storage power station; Step 2: Create the electrical system benchmark factors of the pumped-storage busbar tunnel, assemble the electrical equipment model and the closed busbar, and generate the electrical system model of the pumped-storage busbar tunnel; Step 3: Generate a two-dimensional construction drawing based on the electrical system model of the pumped storage busbar tunnel in step 2; Step 4: Establish a pumped storage busbar electrical system template; Step 5: Generate a two-dimensional construction drawing again based on the pumped-storage busbar electrical system template, overlap it with the projection drawing of the pumped-storage power station building model on the same projection surface, and generate a project construction drawing.

[0006] The present invention is also characterized in that the electrical equipment model library in step 1 includes a PT cabinet model, an electric brake switch model, a circuit breaker model, a starting isolation switch model, a phase change switch model, a PT and lightning arrester cabinet model, and an excitation transformer model.

[0007] Each electrical equipment model in the electrical equipment model library has an electrical equipment model reference factor, and the electrical equipment model reference factor is composed of any one or two of a reference point, a reference line, and a reference plane.

[0008] Each electrical equipment model is changed by adjusting control parameters, and the control parameters include electrical equipment appearance characteristic parameters and electrical equipment electrical characteristic parameters.

[0009] The specific process of step 2 is as follows: Step 2.1: Create the pumped storage busbar electrical system benchmark factors.

[0010] Step 2.2: Associating the electrical equipment model benchmark factors in step 1 with the pumped-storage busbar electrical system benchmark factors. By matching the electrical equipment model benchmark factors in step 1 with the pumped-storage busbar electrical system benchmark factors, electrical equipment model assembly is achieved.

[0011] Step 2.3: Create closed busbar control points based on the busbar tunnel system benchmark factors, connect the closed busbar control points in sequence to realize the assembly of the closed busbar, and generate the pumped storage busbar tunnel electrical system model.

[0012] Among them, the reference factors of the electrical system of the pumped-storage busbar tunnel are composed of any one or two of the reference points, reference lines and reference planes. The reference factors of the electrical equipment model, the closed busbar control points and the reference factors of the electrical system of the pumped-storage busbar tunnel are all parameterized and modified to achieve the changes in the assembly positions of the corresponding electrical equipment models, closed busbars and pumped-storage busbar tunnel electrical systems.

[0013] The specific process of step 3 is as follows: According to the position of the electrical system model of the pumped-storage busbar tunnel in step 2.3, a fixed projection direction is set to generate a projection diagram of the electrical equipment of the busbar tunnel, and then a two-dimensional construction drawing is obtained. The section position of the two-dimensional construction drawing is interrelated with the electrical system model of the pumped-storage busbar tunnel. The two-dimensional construction drawing is equipped with section projection control points. The section projection control points are parameterized and modified to realize the change of the two-dimensional construction drawing.

[0014] Step 4: The specific process is as follows: Integrate the pumped-storage busbar electrical system model and two-dimensional construction drawings to form a busbar electrical system template, package it into the library, and create an interactive interface for the busbar electrical system template.

[0015] The interactive interface includes the electrical equipment model benchmark factors, the pumped storage busbar electrical system benchmark factors, the length of each section of the closed busbar, and the model parameters of each electrical equipment.

[0016] Step 5: The specific process is as follows: Step 5.1, create a pumped-storage power station building model and pumped-storage power station building model benchmark factors, match the pumped-storage busbar tunnel electrical system benchmark factors with the pumped-storage power station building model benchmark factors, and realize the overall assembly of the pumped-storage busbar tunnel electrical system.

DETAILED DESCRIPTION

[0020] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] The arrangement method of the pumped storage electrical equipment of the present invention is as follows: Figure 1 As shown, the following steps are included: Step 1: Create an electrical equipment model library for a pumped storage power station.

[0022] The electrical equipment model library includes PT cabinet general model, electric brake switch model, circuit breaker model, starting isolation switch model, phase change switch model, PT and lightning arrester cabinet model, and excitation transformer model.

[0023] Each electrical equipment model in the electrical equipment model library has an electrical equipment model reference factor, and the electrical equipment model reference factor is composed of any one or two of a reference point, a reference line, and a reference plane.

[0024] Each electrical equipment model changes the electrical equipment model by adjusting the control parameters. The control parameters include the electrical equipment appearance characteristic parameters and the electrical equipment electrical characteristic parameters. Taking the PT cabinet model as an example, the electrical equipment appearance characteristic parameters include: single-phase length, single-phase width, single-phase height, phase spacing, and color; the electrical equipment electrical characteristic parameters include: equipment type, equipment name, type, maximum voltage, rated voltage, rated frequency, number of phases, secondary winding capacity, number of secondary windings, accuracy level, rated secondary voltage, power frequency withstand voltage value, life, maximum transportation weight, etc. When applied to different scenarios, designers can change the electrical equipment model by adjusting the control parameters of each electrical equipment model to adapt to different application scenarios. The selection of control parameters can be set according to actual needs. For example, in the feasibility study stage, it is only necessary to reflect the maximum length, width, and height of the electrical equipment model. As the design continues to deepen, the refinement of the electrical equipment model should also be deepened accordingly, and the key appearance characteristic parameters of the electrical equipment model should be reflected. By creating a parameterized electrical equipment model library, the work of repeatedly creating models during use can be avoided. The required electrical equipment model can be created for assembly only by modifying the control parameters.

[0025] Step 2: Create the reference factors of the electrical system of the pumped-storage busbar tunnel, assemble the electrical equipment model and the closed busbar, and generate the electrical system model of the pumped-storage busbar tunnel.

[0026] Step 2.1: Create the pumped storage busbar electrical system benchmark factors.

[0027] The reference factors of the electrical system of the pumped storage busbar tunnel are composed of any one or two of the reference points, reference lines and reference planes.

[0028] Step 2.2: Associating the electrical equipment model benchmark factors in step 1 with the pumped-storage busbar electrical system benchmark factors. By matching the electrical equipment model benchmark factors in step 1 with the pumped-storage busbar electrical system benchmark factors, electrical equipment model assembly is achieved.

[0029] Step 2.3: Create closed busbar control points based on the busbar tunnel system benchmark factors, connect the closed busbar control points in sequence to realize the assembly of the closed busbar, and generate the pumped storage busbar tunnel electrical system model.

[0030] The electrical equipment model benchmark factors, closed busbar control points, and pumped-storage busbar electrical system benchmark factors are all assigned and modified through parameterization to achieve changes in the corresponding electrical equipment model, closed busbar, and pumped-storage busbar electrical system assembly positions.

[0031] Step 3: Generate a two-dimensional construction drawing based on the pumped storage busbar electrical system model in step 2.

[0032] According to the position of the electrical system model of the pumped-storage busbar tunnel in step 2.3, a fixed projection direction is set to generate a projection diagram of the electrical equipment of the busbar tunnel, and then a two-dimensional construction drawing is obtained. The section position of the two-dimensional construction drawing is interrelated with the electrical system model of the pumped-storage busbar tunnel. The two-dimensional construction drawing is equipped with section projection control points. The section projection control points are parameterized and modified to realize the change of the two-dimensional construction drawing.

[0033] Step 4: Create a pumped storage busbar electrical system template.

[0034] Integrate the pumped-storage busbar tunnel electrical system model and two-dimensional construction drawings to form a pumped-storage busbar tunnel electrical system template, package it into the database, and create an interactive interface for the busbar tunnel electrical system template.

[0035] The interactive interface includes the electrical equipment model benchmark factors, pumped storage busbar electrical system benchmark factors, the length of each section of the closed busbar, and the model parameters of each electrical equipment. By packaging the busbar electrical system template into the library, designers can avoid misoperation, and creating an interactive interface is convenient for operation, which is conducive to the promotion of the model.

[0036] Step 5: Generate a two-dimensional construction drawing again based on the pumped-storage busbar electrical system template, overlap it with the projection drawing of the pumped-storage power station building model on the same projection surface, and generate a project construction drawing.

[0037] Step 5: The specific process is as follows: Step 5.1, create a pumped-storage power station building model and pumped-storage power station building model benchmark factors, match the pumped-storage busbar tunnel electrical system benchmark factors with the pumped-storage power station building model benchmark factors, and realize the overall assembly of the pumped-storage busbar tunnel electrical system.

[0038] Step 5.2, select the encapsulated pumped-storage busbar electrical system template, set the reference points of each electrical equipment model, the reference points of the pumped-storage busbar electrical system, the length of each section of the closed busbar tube, and the control parameters of each electrical equipment model, generate the two-dimensional construction drawing again, and obtain the projection of the pumped-storage power station building model on the current projection surface, overlap the projection of the pumped-storage power station building model with the two-dimensional construction drawing, and generate the project construction drawing.

[0039] When the design requirements change, the parameters are adjusted according to the actual project requirements. The electrical system template of the pumped storage busbar tunnel will update the two-dimensional construction drawings according to the actual parameter changes to achieve rapid changes and drawings. This real-time linkage between the two-dimensional construction drawings and the three-dimensional models reflects the global uniqueness of the data source, which is the basis of digital full life cycle design. It is more reusable, greatly saves the design time of designers, avoids the common drawbacks of repetitive modeling and repeated drawings in traditional design methods and other digital design software, and effectively improves work efficiency. At the same time, it ensures the uniformity of data, avoids the inconsistency between two-dimensional data and three-dimensional data caused by remodeling, and helps the forward design of all disciplines of pumped storage to move forward continuously.

After completion, enter the two-dimensional construction drawing interface. At this time, since the pumped-storage busbar tunnel electrical system template has embedded the two-dimensional construction drawing for the layout of electrical equipment, as shown in the following table. Figure 5 , Figure 5It is a two-dimensional construction drawing of the electrical system template of the pumped-storage busbar tunnel. The two-dimensional construction drawing includes the busbar tunnel electrical equipment plan layout, busbar tunnel equipment cross-section, main lead-out joint schematic diagram, and busbar tunnel equipment cross-section. The scale is 1:100. The dimensions in the figure are measured in millimeters except for the elevation and pile number in meters. Therefore, it is only necessary to obtain the corresponding projection diagram of the pumped-storage power station building model according to the current projection surface and overlap it with the existing electrical equipment projection diagram to generate the project construction drawing. Figure 6 As shown, Figure 6 It is a project construction drawing, specifically, an axonometric drawing of the busbar hole electrical equipment obtained by overlapping the projection drawing of the two-dimensional construction drawing with the projection drawing of the pumped-storage power station building model on the same projection surface. The scale is 1:100, and the dimensions in the figure are measured in millimeters except for the elevation and pile number in meters. In summary, it can be seen that the method for arranging pumped-storage electrical equipment of the present invention, compared with the later simultaneous projection of the building model and the electrical equipment model, presents the professional achievements separately and distributes the professional achievements on different layers. The building model and the electrical equipment model are completed by different professionals, which reduces the difficulty of the staff and effectively improves the work efficiency.
