摘　　要：在电力系统机网暂态过程中往往存在有多次开关操作，导致在暂态过程数值计算中产生数值振荡，本文介绍两种新的能有效消除数值振荡的算法─—在空间矢量坐标系下的带特征因子的欧拉法和不带特征因子的吉尔法，文中就电感元件推导了这两种算法的数学模型，分析了它们的特点。与通常采用的方法相比，这两种算法具有计算精度较高、算法简单、节省机时、适应性广的特点。文中以两个简单算例验证了这两种算法的正确性和消除数值振荡的有效性。This paper presents two novel mathematical models of the electrical elements of power systems for the digital simulations of the transients.These models can be easily and successfully used to eliminate the numerical oscillations in the duration of the simulation calculations,which are caused by the frequent changes of the topogical structures of the networks.Comparing with the treatment methods we usually use these models are with higher precisions and much more convenient to use.
