摘要
利用连续光滑的解析函数式模拟了变压器的非线性磁化特性。介绍了计及剩磁、磁饱和和磁滞影响的单相变压器模型。对描述励磁支路暂态的非线性微分方程进行了求解,并用EMTP程序进行仿真。试验结果证明了所提出模型及算法的正确性。
The smooth and continuous functions are used to simulate the non-linear magnetizationcharacteristics of transformer. The single-phase transformer model considering residual flux, magnet-ie saturation and hysteresis is introduced. The non-linear differential equation for transience in ex-eitation circuit is derived and is emulated with the program EMTP. The model and its algorithmare verified with experimental results.
