【 摘 要 】

The voltage transformer is a common nonlinear inductor in the power system. The core nonlinearity caused by saturation, hysteresis and eddy current makes it difficult to describe the dynamic magnetization of the core. At present, there are many different saturation models for nonlinear inductors. Different models are used to simulate ferromagnetic resonance, which will result in different results. In this paper, based on ATP-EMTP electromagnetic transient simulation software, the simulation of different voltage transformer saturation model is carried out, the calculation error is analyzed, and the results of different models are compared.
