| 摘 要： | 介绍一种含铁心元件网络的暂态计算方法。在这一方法中 ,首先建立铁磁元件励磁支路的模型 ,即以光滑连续的公式来描述非线性励磁特性 ,取代传统的分段线性化模型 ,然后再给出含铁心元件网络的暂态算法。该算法从非线性励磁支路的求解出发 ,通过对剩余线性网络的暂态计算 ,得到整个网络的全解。应用该算法 ,所得计算结果能够与实验结果较好地拟合

| Abstract: | This paper presents an efficient method for transient calculation of power system.A new model is developed to represent the magnetzing characteristics, in which the magnetizing curve is described by a continuous and smooth manner.Moreover a calculation method is also proposed based on the model.In the proposed method, the magnetizing branches are first solved by the semi explicit Runge Kutta algorithm, and then the transient responses can be obtained for the system network. A comparison has been made between calculated and experimental results and a better agreement appears. |
