Application of Satellite Image in Substation Location

The selection of substation sites is an important part of power grid planning. The reasonable locations of substations not only affect the investment in the construction in the early stage, but also play a vital role in the operation of power grid in the later stage. A method of substation location based on satellite images is proposed in this paper. With the rapid development of technology, it has become possible to obtain high-definition satellite images. Satellite images are converted into corresponding data, and a wide-area geographic information database is established to build actual three-dimensional geographic models, which can save manpower, material resources and time consumption of on-site inspections. In the 3D model, a large amount of attribute data can be directly reflected, and the visualization degree is stronger. The basic process and advantages of this method are analyzed and summarized, and the feasibility is verified by a case.
