Abstract: Although the traditional digital power plant technology can attain the digital mode of enterprise construction and management, it still lacks the conditions and features of high intelligence in the aspects of the breadth of information collection and the depth of information utilization. In this paper, by taking the production characteristics of power plant into consideration, an intelligent all-digital technology system applicable for power plant is proposed on the basis of the technology of digital power plant, and the concept, composition and basic relationship between the elements of intelligent all-digital technology is aslo proposed, expounds the basic structure and principle of intelligent all-digital system, elaborates the intelligent operation mode of intelligent subject, and explores the application scheme of intelligent all-digital technology in power plant. In this system, the intelligent subject and digital technology are organically combined to increase and expand the breadth and depth of data information usage, i.e., expand the paths and means of information acquisition and collection to increase the breadth of information, and conduct in-depth analysis, mining and reutilization of data information by introducing more intelligent calculation algorithms and analysis methods. At the same time, the new data and knowledge generated by the system can be fed back to the existing all-digital system continuously to achieve the self-adjustment and self-organization of the system, in which the traits of intelligence are fully exhibited.
