Abstract: Digital security management and control technology, based on image data sources, plays an important role in maintaining the safety of power production. In response to the challenge of comprehensive risk management in the power risk, this paper first takes typical safety accidents as examples to analyze the characteristics of random spatial distribution, transient temporal distribution, and multi-source physical field distribution of power risks. Then, this paper aims to expand the connotation and extension of the image technology by proposing the concept of holographic images from the perspective of security, and establishes a framework of power holographic images. Subsequently, the key technologies involved in the construction of holographic images are described, namely, sensor technology, the mechanism analysis and inversion techniques of security risk, physical field imaging technology, multiphysics fusion technology, security risk warning, and analysis technology. Finally, the problems and technical challenges of security control from the perspective of holographic imaging are analyzed, providing a comprehensive methodology for power safety control.
