Abstract
With the rapid development of the power system and the increasing complexity of the power grid structure, users’ demand for information-based management of the power distribution network is growing, and the need to improve various power production service standards is becoming increasingly urgent. Geographic information systems (GIS) are a natural combination of geographic and data attributes that are particularly well suited to the management of urban pipeline systems such as distribution and telecommunication networks. This paper discusses the current application characteristics and challenges of 3D GIS in the power system. A 3D graphic analysis model of the power grid and its realization method are proposed using 2D GIS and scene simulation technology combined with object-oriented design method. The problems that exist in current urban distribution facility management are solved in this paper through the effective integration of information construction and distribution facility management, and the goal of refined management is achieved on this basis. More and more complex 3D spatial data can be processed more realistically and intuitively with 3D GIS.
Highlights
Transmission line engineering is a large-scale undertaking
It can be seen that the distribution network engineering scene simulation method based on 3D geographic information system (GIS) proposed in this paper can solve the network planning problems with different heterogeneous backgrounds and has good application potential
With the progress and development of science and technology, 3D GIS technology is developing at an unprecedented speed and plays an important role in the design, operation, and maintenance of power grid
Summary
Regional spatial information is in high demand for everything from power grid planning, design, and construction to operation, management, and maintenance [1, 2]. A geographic information system (GIS) is a data storage, analysis, and presentation system for spatial and nonspatial data [2]. The three-dimensional distribution network system consists of a three-dimensional digital terrain model, high-resolution remote sensing image data, three-dimensional power facilities and equipment model, three-dimensional visual simulation of power grid equipment, and a power grid construction area and allows users to browse, roam, position, and perform other operations in the three-dimensional scene interactively [7, 8]. The management of distribution network facilities requires integrated management of power equipment, auxiliary equipment, and their operating environment [11]. The analysis, evaluation, and decision-making of problems get rid of the limitation that 2D GIS is only based on plane problem-solving
