Abstract
The invention relates to a power grid visualization system and a power grid visualization method based on a three-dimensional geographic information system (GIS) technology. Models to be loaded are divided into different model loading subtasks according to the difference of object types included in a scene to be loaded, and model files are called in parallel from a plurality of subtasks in a multi-thread mode; and meanwhile, on the basis that loading tasks are divided into a plurality of model loading subtasks according to the loaded object types, model files of objects of each type are only read once, moreover, reuse of the model files is not limited to a client loading task, different clients can reuse the read model files, and the characteristics of limited type and relatively consistent specification of power equipment are fully considered, so that rereading of the model files of the same type is avoided.
