A substation intelligent optimization design method based on a function module library

Abstract

This invention relates to an intelligent optimization design method for substations based on a functional module library. A general design scheme library for substation projects is established, and a method for dividing substation functional modules is proposed. Typical design schemes are divided into modules according to different regions, voltage levels, and electrical equipment functions, establishing a three-dimensional functional module library for intelligent substation design. Basic engineering information such as voltage level, outgoing line scale, and layout is input and intelligently analyzed and matched with typical functional modules in the scheme library. The modules are then merged using the same coordinate system to find the optimal reusable scheme. Based on the actual engineering situation, the matched scheme is intelligently optimized. Simultaneously, the rationality of the intelligent optimization scheme is verified through three-dimensional verification functions, including refined verification of the three-dimensional model, soft and hard collision checks, high-voltage equipment selection calculations, lightning protection calculations, safe clearance calculations, and fire protection verification.

Description

Technical Field

[0001] This invention relates to a substation intelligent optimization design method based on a functional module library. Background Technology

[0002] 3D design refers to the integrated application of 3D modeling technology and digital collaborative design technology to complete the 3D visualization design and information integration of power transmission and transformation projects based on engineering information and geographic information data.

[0003] The existing three-dimensional design methods for substation projects mainly involve collaborative design by various disciplines on the same design platform. This design process is repeated for each project. Specifically, it involves designing the main wiring, integrating the building structure design with the layout of equipment, conductor connections, grounding, lighting, plumbing, and other facilities.

[0004] Because each project has different characteristics, adjustments need to be made during the engineering design process based on the design scheme, such as the outgoing line direction, outgoing line scale, and layout method. Low-value repetitive operations are still required.

[0005] Existing design methods are time-consuming, only consider engineering design, lack reusability, and require repeating the traditional design process when design schemes need to be adjusted, resulting in low design efficiency. Summary of the Invention

[0006] The purpose of this invention is to provide a substation intelligent optimization design method based on a functional module library, which can achieve reuse and has high design efficiency.

[0007] To achieve the above objectives, the technical solution of the present invention is: a substation intelligent optimization design method based on a functional module library, comprising the following steps:

[0008] Step 1: Establish a three-dimensional general design scheme library for substation projects. Based on the voltage level of 35kV to 220kV, the layout forms of fully indoor, semi-indoor, and outdoor substations, the wiring forms including double busbar single-section connection, double busbar connection, and single busbar section connection, and the project scale, establish a three-dimensional general design scheme library for substation projects.

[0009] Step 2: Considering factors including the voltage level and function of electrical equipment, divide the substation project into functional modules. Divide the power distribution equipment into 220kV power distribution equipment bay modules, 110kV power distribution equipment bay modules, 35kV power distribution equipment modules, 10kV power distribution equipment modules, as well as reactive power compensation device modules, grounding transformer and arc suppression coil device modules, cable and accessory modules, and substation secondary modules. Associate and match the parameter information and plan and section layout diagrams of the equipment and facilities in each functional module with the modules.

[0010] Step 3: Set the matching relationships between schemes and modules, and between modules, and use them as key information conditions that can be selected when matching modules in the module library;

[0011] Step 4: For the functional modules divided in Step 2, input the high, medium and low voltage levels of the substation, the wiring information of each voltage level, and the layout information of the substation. Use key design parameters and the functional modules in the solution library for intelligent analysis and matching to determine the optimal functional module. Combine and merge the modules through the same coordinate system to select the optimal engineering design scheme.

[0012] Step 5: For the functional modules matched in Step 4, determine whether to use the module by checking the key parameters and plan / section diagrams associated with the functional modules.

[0013] Step 6: Based on the basic information of the project, including voltage level, layout, construction scale, and outgoing line direction, perform intelligent matching of the project design scheme library and functional module library; for multiple pre-selected schemes, assist manual intervention to filter the scheme options; during the filtering process, input multiple project parameters and refer to the associated plan and section drawings to form the final matched scheme.

[0014] Step 7: For the matched scheme, intelligent optimization design of the scheme is carried out in combination with the actual engineering design; based on the fine verification of the three-dimensional model, through the parametric design function of the power distribution device axis network, the bays are arranged according to rules, the equipment spacing is adjusted in batches, the conductors are linked with the equipment, and the support structure is quickly adjusted.

[0015] Compared with the prior art, the present invention has the following advantages: the method of the present invention can be reused and has high design efficiency. Attached Figure Description

[0016] Figure 1 This is a flowchart of a substation intelligent optimization design method based on a functional module library according to the present invention. Detailed Implementation

[0017] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings.

[0018] like Figure 1 As shown, the present invention provides a substation intelligent optimization design method based on a functional module library, comprising the following steps:

[0019] Step 1: Establish a three-dimensional general design scheme library for substation projects. Based on the voltage level of 35kV to 220kV, the layout forms of fully indoor, semi-indoor, and outdoor substations, and the wiring forms such as double busbar single segment connection, double busbar connection, and single busbar segment connection, and according to the project scale, establish a three-dimensional general design scheme library for substation projects.

[0020] Step 2: Considering factors such as the voltage level and function of the electrical equipment, divide the substation project into functional modules. Divide the power distribution equipment according to voltage level into 220kV power distribution bay modules, 110kV power distribution bay modules, 35kV power distribution modules, 10kV power distribution modules, as well as reactive power compensation device modules, grounding transformer and arc suppression coil device modules, cable and accessory modules, and substation secondary modules. Associate and match the parameter information and plan / section layout diagrams of the equipment and facilities in each functional module with the modules.

[0021] Based on the layout characteristics of electrical equipment and its associated civil engineering facilities, the corresponding equipment layout is completed, and parameterized grid lines are added to link them with the electrical equipment. This enables parameterized adjustments such as equipment movement along the grid lines and provides automatic conductor repair functionality.

[0022] The electrical equipment and civil engineering models associated with the parametric grid are identified as a parametric layout area through the parametric area function. This area enables the automatic adjustment of electrical equipment and the automatic layout of civil engineering models. This area is exported in a specific format and stored uniformly to finally establish a three-dimensional functional module library.

[0023] in:

[0024] (1) The 220kV power distribution equipment bay module includes: overhead outgoing line bay, segmented bay, bus tie bay, bus equipment bay, main transformer incoming line bay, bus equipment and outgoing line bay, bus tie and outgoing line bay, etc.

[0025] (2) The 110kV power distribution equipment bay module includes: overhead outgoing line bay, bus tie bay, bus equipment bay, main transformer incoming line bay, bus equipment and outgoing line bay, bus tie and outgoing line bay, etc.

[0026] (3) 35kV power distribution equipment bay modules include: single-row arrangement, double-row arrangement, switch cabinet, 35kV bus bridge, etc.

[0027] (4) 10kV power distribution equipment bay modules include: single-row arrangement, double-row arrangement, switch cabinet, 10kV bus bridge, etc.

[0028] (5) The reactive power compensation module includes: 35kV parallel capacitor and 10kV parallel capacitor.

[0029] (6) The grounding transformer and arc suppression coil device module includes: arc suppression coil complete set of equipment and grounding transformer.

[0030] (7) The cable and accessories module includes: conductors, cables, insulator strings, equipment clamps, cable terminals, lighting fixtures, post insulators, surge arresters, etc.

[0031] (8) Substation secondary modules include: switch cabinets, fire protection devices, auxiliary control devices, etc.

[0032] Step 3: Set the matching relationship between scheme-module and module-module, and use it as the key information condition that can be selected when matching the module library. For example, when the nature of the substation is an outdoor substation, double busbar or double busbar single segment connection is adopted, and when it is an indoor substation, internal bridge, line transformer group or single busbar segment connection is adopted.

[0033] Step 4: For the functional modules divided in Step 2, input the high, medium and low voltage levels of the substation, the wiring information for each voltage level, and the substation layout information. Use key design parameters and the functional modules in the solution library for intelligent analysis and matching to determine the optimal functional module. Combine and merge the modules through the same coordinate system to select the optimal engineering design scheme.

[0034] Step 5: For the functional modules matched in Step 4, manual intervention can also be performed. By viewing the key parameters and plan and section diagrams associated with the functional modules, it can be determined whether to use the module.

[0035] Step 6: Based on the basic information of the project, including voltage level, layout, construction scale, and outgoing line direction, perform intelligent matching between the project design scheme library and functional module library. For the multiple pre-selected matching schemes, manual intervention is used to filter the options. During the filtering process, multiple project parameters are input, and related plan and section drawings are consulted to form the final matched scheme.

[0036] Step 7: For the matched scheme, intelligent optimization design is carried out based on the actual engineering design. Based on the refined verification of the 3D model, and through the parametric design function of the power distribution device's axis network, features such as regular bay arrangement, batch adjustment of equipment spacing, conductor linkage with equipment, and rapid adjustment of support structures are achieved.

[0037] During the intelligent optimization process of substation solutions, three-dimensional verification functions are performed, including model soft and hard collision checks, high-voltage equipment selection calculations, lightning protection calculations, safety clearance calculations, and fire protection verification. This fundamentally avoids rework caused by design errors, resulting in an intelligent optimized design solution.

[0038] The above are preferred embodiments of the present invention. Any changes made to the technical solution of the present invention that do not exceed the scope of the technical solution of the present invention shall fall within the protection scope of the present invention.
