The local simplified modeling method is a calculation way which simplifies the simulation moel and can guarantee the computational accuracy. The effects of local simplified modeling method are studied in detail based on TEAM P21a-2、P210- B under various working conditions,the works are investigated the calculation result of the ed? dy current loss and the leakage magnetic flux of the transformer structure with the experiment results. The simulation results are in good with the experimental results,namely the local simplified modeling method can be applied in engi? neering calculation area. On the condition of limited calculation resources,how to simplify the modeling becomes a major content of scientific researchers. The validation of simplified modeling method has important significance for reasonable modeling and effective simulation of large power transformer.
