The current simulation method of DC bias magnetization simulation cannot guarantee the simulation of magnetization curve and excitation current of transformer under DC bias magnetization with sufficient accuracy under the premise of real-time simulation and easy implementation. In this paper, we propose a method to simulate the ex-citation characteristics of transformers considering DC bias magnetization, and use the magnetization curve under DC bias magnetization to calculate the distortional excitation current of transformers.
