System and method for power transmission and transformation project three-dimensional-aided preliminary design

Abstract

A power transmission and transformation project three-dimensional-aided preliminary design system comprises a data storage unit, a power transmission and transformation project typical model base unit, a data exchange interface, a three-dimensional rendering engine unit and a spatial analysis unit. The data storage unit is used for storing and managing spatial data and non-spatial data needed to be referenced in designing power transmission and transformation projects of various types, the power transmission and transformation project typical model base unit is used for storing power transmission and transformation equipment three-dimensional models of various types and with representative significance by combining actual power transmission and transformation project design, the data exchange interface is used for inputting and outputting power transmission line design tower optimized arranging software data formats, the three-dimensional rendering engine unit is used for creating, loading and rendering three-dimensional scenes, and the spatial analysis unit is used for providing spatial measuring and spatial analysis functions. The power transmission and transformation project three-dimensional-aided preliminary design system created by applying the three-dimensional GIS (geographic information system) technology integrates data of various types needed at a preliminary design stage, comprehensively judges various factors influencing power transmission line route selection and transformer station address selection by stacking of the data of various types, and overcomes defects of poor up-to-date state, poor visuality and the like of topographic maps in conventional methods.

Description

technical field [0001] The invention relates to a three-dimensional geographic information system (3DGIS, Geographic Information System), in particular to a three-dimensional auxiliary preliminary design system and method for power transmission and transformation projects applied to power systems. Background technique [0002] In power grid construction, transmission line route selection and substation site planning are important contents in the preliminary design stage of power transmission and transformation projects, which are directly related to the economic and technical indicators of the project and affect project construction investment and operation and maintenance benefits. [0003] The design of high-voltage transmission lines is to select an optimal transmission line from the power plant to the substation according to certain design principles. According to the design requirements of transmission lines, when designing optimal lines, designers are often required to...

Problems solved by technology

[0007] This approach has obvious shortcomings: ①The topographic map is poor in current situation, because the map was formed earlier, it can no longer truly reflect the current situation of the landform; ②The visibility of the topographic map is poor, and the traditional drawings are represented by contour lines and elevation points Three-dimensional information cannot be interpreted intuitively; ③The various map data collected are not uniform in terms of file format and coordinate system, which brings inconvenience to comprehensive use; ④On-site surveys mainly use low-precision visual inspection. It is easy to leave hidden path hazards at important features; ⑤Because there is no cross-section data, designers can only rely on experience to arrange poles on the map, and the depth and quality of the design are difficult to guarantee
