The invention relates to a three-dimensional holographic generation method for intelligent power grid visualization application. Compared with the prior art, the method enables a defect of lack of an intelligent power grid visualization method to be overcome. The method comprises the following steps that: a pyramid level modeling is carried out on a three-dimensional landscape and leveling and block separation are carried out on a landscape image and DEM data based on the pyramid level structure; three-dimensional modeling is carried out on a city building and components thereof by a simple model way and a spatial index structure is established; two-dimensional vector data are laminated on the three-dimensional landscape model; three-dimensional modeling is carried out on power equipment; and a visualization application model is generated. With the method, reproduction of a three-dimensional hologram is realized; and with combination of related professional software of power automation, three-dimensional holographic application system of intelligent power grid visualization is formed.
