This paper presents iterative EMT algorithms for Surge Arrester, also commonly named Metal Oxide Varistors, within 2 different simulation solvers; the State-Space-Nodal solver of ARTEMiS and the nodal admittance method of HYPERSIM. The proposed algorithm, based on fixed-point iteration, allows precise simulation of nonlinear models with minimal extra simulation time cost. Cases are presented in the paper in which the iteration feature clearly improves the simulation accuracy. . e, ]; R2 i* ?. v' ]* v! t3 o9 Y- `) }: p8 y
这篇文章介绍了电涌放电器的迭代算法。电涌电阻器通常也被称为金属氧化电阻器,可用于两种不同的仿真求解器;即用于ARTMiS的空间节点求解器和HYPERSIM使用的节点导纳方法。文中所提出的算法基于固定点迭代,可在最少的时间内实现对非线性模型的精确仿真。文章还列举了体现迭代特征显著改善仿真精确度的案例。; K( Z3 \3 ~9 o9 K' p, ?
