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.
