Research on the physical mechanism data space mapping method of power grid transmission and transformation equipment based on finite element analysis method

As an important role of the power system, the power transmission and transformation equipment (PTTE) performance directly affect the safety and stability of the power grid. This work aims to investigate the mapping relationship between the physical mechanism and data space of PTTE in the power grid through finite element analysis method. By conducting a detailed analysis of the operating characteristics of PTTE, identifying the main physical fields involved, and using discretization methods to establish and optimize the grid model of the equipment, coupling calculations of electromagnetic, thermal, structural, and fluid are carried out. Finally, the physical mechanism data space mapping of different equipment is constructed, providing a theoretical basis for the state monitoring and fault diagnosis of PTTE in the power grid.
