Method for establishing three-dimensional component model database of power grid equipment and facility

Abstract

The invention provides a method for establishing three-dimensional component model database of power grid equipment and facility, which is a three-dimensional component model library of power grid equipment and facility, which can be virtually and flexibly assembled and which can be used for realizing object-oriented component modeling. By classifying high-precision three-dimensional model of each component part of power equipment and designing a sign, the method of the invention enables the three-dimensional model used in an electric power design and management industry to load, render and develop to a stage of accurately describing and designing according to different equipment modules from a single entity model. The method for establishing three-dimensional component model database of power grid equipment and facility of the invention can be used for greatly reducing workload of electric power project three-dimensional digital design and greatly improving operating speed and efficiency of a power grid three-dimensional GIS system.

Description

technical field [0001] The invention relates to the technical field of three-dimensional geographic information system of electric power system and electric power engineering design, in particular to a method for establishing a three-dimensional componentized model database of power grid equipment and facilities. Background technique [0002] The power grid GIS system is to organically integrate the geographical location, production operation, operation management and other information of the equipment and facilities of the power grid enterprises in the links of power generation, transmission, transformation, distribution, and power consumption with basic geographic information such as two-dimensional / three-dimensional terrain, landforms, and features. A unified system for integrating and publishing presentations. [0003] In recent years, the two-dimensional GIS technology of the power grid has been widely used in the production, design, operation and management of the powe...

Problems solved by technology

[0005] 1. Directly loading the model generated by 3D modeling technology into the 3D environment cannot fully reflect the 3D characteristics of power equipment. Specifically, the mainstream 3D model is loaded and rendered as a unified entity, which cannot well reflect the components of the equipment. Concrete states, interrelationships, and fine-grained features;

[0006] 2. The mainstream 3D model creates, loads and renders a complex group organization composed of many power grid equipment and facilities as an entity object. On the one hand, it improves the requirements for the model operating environment and increases the difficulty of maintaining the model library. On the other hand, the operating efficiency is relatively low. also lower;
