Abstract: Amidst the multiple waves of national strategy, energy revolution, technological innovation, and digital existence, the digital transformation of power grid enterprises, as the core hub of the energy industry, has become an inevitable trend. This paper discusses the application mode of digital standards based on scenarios. It starts by analyzing the general theoretical model of standardization based on scenarios and explores how to associate scenario unit needs with standard clause knowledge content to better apply standards, providing a pathway for the application of digital standards. Subsequently, combining the characteristics of digital standards, the paper analyzes the overall thinking and application logic of building digital standard applications, clarifying the internal relations of the digital standard application model based on scenarios. Finally, using the operation and maintenance inspection module as an example, the feasibility and effectiveness of the intelligent application of digital standards in typical business scenarios based on knowledge association are analyzed. This provides reference significance for continuously delving into business application scenario needs and fully unleashing the value of standards.
