Review for Digital Prototype Technology of High-voltage Circuit Breakers
摘要
Abstract
High-voltage circuit breakers are critical devices for control and protection in power systems.They are characterized by high voltage,large current,enclosed structures,highly transient operating processes,and difficulty in directly measuring internal states,which pose challenges to condition assessment and intelligent operation as well as maintenance.In this paper,the key technologies of digital prototype for high-voltage circuit breakers is re-viewed.The key technologies of digital twins and the functional positioning of the digital prototype is firstly ana-lyzed.Then,the digitalization requirements of high-voltage circuit breakers are summarized from such multiple physical domains as interruption,insulation,temperature rise and mechanical operation.The reconstruction require-ments of internal unmeasurable states under low-intrusion sensing conditions are discussed,and the main technical challenges faced by the digital prototype are summarized in terms of real-time performance,physical interpretability and model consistency.Furthermore,real-time forward/inverse modeling,model calibration and consistency evalua-tion,as well as physics-data fusion modeling methods for online applications are reviewed.Finally,the development trends of the digital prototype for high-voltage circuit breakers are discussed from the perspectives of multi-source data fusion,rapid model construction,trustworthy evaluation and standardization.关键词
