摘要
本文指出研究变压器过渡过程的一般方法的不足之处,提出了新方法。首先引入φ=f(i)将电路微分方程组补充完整。然后对磁化曲线用数理统计方法和计算机进行拟合,找出拟合函数。再运用四阶龙格一库塔法求解电路微分方程组。这样新的方法就更准确、可靠、快速了。
This article first pionted out the shortcoming of the conventional method for studying the unloaded switch-in trcmsitioned process of trcmsformer and presents new method first of all a equation φ=f(i) is introduced to complete the circuit differential equations, then magnetizing curve is smoothed by means of mathematical statistics and coraputer to find out the smoothing function. Finally the circuit differential equations is solved by means of fourth-order of Runge Kutta method. The new method is proved to be of much more accurate faster and more reliable
