Substation digital twin system and application method and system thereof

The invention discloses a transformer substation digital twin system and an application method and system thereof. Firstly, a scene three-dimensional model is established in a multi-level modeling mode; then, on the basis of a scene three-dimensional model, multi-source data are accessed, and meanwhile, the functions of the three-dimensional model, data fusion, visual presentation, space calculation and risk management and control, full-life-cycle management and control of equipment, virtual-real combination, industry application and the like are added into a digital twinning system, so that plant-station digital twinning in a real sense is realized. Meanwhile, a scene database of key equipment and a daily inspection key position of a plant station is established, and field operation and maintenance personnel or operating personnel can realize augmented reality application of digital twinning in inspection operation, so that the practical application of the digital twinning system in field operation and maint
