To improve the intelligent level of operation and management for building electrical systems

this study systematically investigates the application paths of digital twin technology in the field of building electrical engineering. A technical framework centered on the structured expression of modeling parameters

a data-driven sensing mechanism

and the linkage logic of the control platform is established

forming a digital twin implementation scheme suitable for building electrical systems. Combining architecture analysis and system modeling

this study extracts key implementation links and verifies the proposed method with practical engineering cases. The results show that the application path can effectively improve the state visualization and dynamic response capability of building electrical systems

providing feasible technical support for the intelligent operation and maintenance as well as full-life-cycle management of building electrical systems.
