摘要：
To maintain quality, performance and competiveness, the finite element method is increasingly utilized not only for the verification of contractual values of existing transformers, but also for the design optimization of transformers. The paper presents 3D finite element analyses of power transformers in the range of 30 MVA to 200 MVA with the aim of an optimization of the tank wall shape and the tank wall shielding with regard to eddy current losses. Thereby, novel modelling strategies for the nonlinear eddy current carrying material will be investigated. The results obtained from various finite element analyses are compared with measurements.
