| 在变压器等效电路的基础上，通过对变压器磁化曲线的分段线性化处理，列写了一组约束变压器空载合闸后暂态过程中磁通变化的微分方程。通过求解该组微分方程，得出了一组描述暂态过程中磁通变化规律的数学表达式。然后把磁通变化规律按不同的时间段来描述，得到一组用于对励磁涌流进行数字仿真的迭代公式，并据此画出了励磁涌流过程中磁通与电流及其分量的变化曲线，分析了它们的典型局部变化特征并给出合理的解释。最后经过数学推导，分析了导致励磁涌流衰减的原因、励磁涌流衰减速度的变化规律及影响励磁涌流衰减速度的因素，得到一些有益的结论。仿真结果证明了所得结论的正确性。 |

| A group of differential equations were proposed, based on the transformer equivalent circuit, for constraining the flux variation during the transient process of a transformer after no-load closing by piecewise linearization. A group of mathematical expressions depicting the flux variation law during the transient process were obtained by solving the above differential equations. Thereafter, another group of iterative formulae for the digital simulation of the inrush current were obtained by describing the flux variation law at different time segments, based on which the variation curves involving flux, current and their (its?) components during the inrush current process were drawn. Moreover, their typical local variation characteristics were analyzed, and a reasonable explanation was given. Finally, the reason for the inrush current attenuation, the variation law of the inrush current attenuation rate, and the factors affecting the inrush current attenuation rate were analyzed by mathematical derivation, and some useful conclusions were drawn that were confirmed by the simulation results. |
