基于区域分解求解多尺度HVDC地电流场的广义极小残量迭代算法
Gaoya dianqi, 2018 为准确求解高压直流输电（HVDC）单极运行或故障状态下的入地电流场,需要建立更加贴近实际的计算模型。文中在建模时将接地极的具体尺寸考虑在内,并且将大地模型尺寸增大到上千公里,使得模型更加贴近实际,可以得到更准确的计算结果。考虑到接地极和大地区域尺寸的差距,模型属于多尺度模型。针对多尺度模型,文中采用重叠型的区域分解法,将包含接地极在内的小区域从整体模型中分解出来,独立建模求解。选取虚拟边界上的电位为迭代变量,将整个问题最终转化为非对称实数线性方程组。针对区域分解的迭代 ...

The convergence of the GMRES linear solver is notoriously hard to predict. A particularly enlightening result by [Greenbaum, Pták, Strakoš, 1996] is that, given any convergence curve, one can build a linear system for which GMRES realizes that convergence curve. What is even more extraordinary is that the eigenvalues of the problem matrix can be chosen
