Computer Aided Maintenance(CAM+)Framework and Key Technologies Towards Digital Twin Transformers
摘要
Abstract
It is of significant value to develop digital twin transformers to support the intelligent operation and mainte-nance of power equipment.Currently,transformer possesses the general functions of computer-aided design and engineering simulation,however,the operation and maintenance oriented scenarios and performance digital twins are still in their infancy.Therefore,this paper proposes a new pattern which further expands computer-aided design,engineering simulation,and manufacturing into computer-aided maintenance+(CAM+)for electric power equipment,including func-tions such as scenario updating,virtual-real fusion,fault location,and intelligent operation and maintenance.Firstly,this paper introduces the connotation of CAM+,and proposes the technical architecture of CAM+ pattern for digital twin transformers by combining the digital twin architecture of power equipment.Then,the key technologies involved in the CAM+ pattern,such as 3D scene visual modelling,high-precision sensing,coupled multi-physical field modeling and fast computation,dynamic deduction of virtual-real fusion,multi-source data fusion,intelligent assessment of state,and knowledge graph,are overviewed.Finally,the application of CAM+ for transformer scenario updating,parametric twin-ning and intelligent operation and maintenance is analyzed and the future challenges and directions of CAM+ are summarized.关键词
