Application Research of Multi-site Smart Substation based on Digital and Physical Simulation Technology

The multi-site smart substation has the characteristics of intelligent operation and maintenance, data fusion and economic efficiency, which can meet the needs of intelligent, digital and zero-carbon development. Thus, this paper establishes a multi-site smart substation scheme based on digital and physical simulation technology. First, it analyzes the intelligent operation and maintenance application of operation, inspection and defect identification in the intelligent operation and maintenance of the substation, and the data fusion application to improve the information judgment ability. The economical and efficient application of carbon photovoltaics; secondly, the data model, 3D model and simulation model of digital and physical simulation technology are analyzed; finally, the economy, intelligence and effectiveness of multi-site smart substations are verified by practical example simulation.
