论文摘要
研究了基于限制添加剂Schwarz结构域分解的迭代耦合算法，以与使用动态相位器建模的混合电磁（EMT）和瞬时稳定性（EMT）和瞬态稳定性（TS）共同仿真电路。该共模拟算法不会引入共模拟步骤中交换的数据之间的任何延迟。迭代方法的纯线性收敛属性允许它通过非侵入性Aitken加速后处理后加速到真正的解决方案，即使域分解界面条件使迭代方法具有分歧。这提供了一种对分裂不敏感的方法。提供了结合EMT和TS建模的线性RLC电路上的数值测试。
An iterative coupling algorithm based on restricted additive Schwarz domain decomposition is investigated to co-simulate electrical circuits with hybrid electromagnetic (EMT) and transient stability (TS) modeled using dynamic phasors. This co-simulation algorithm does not introduce any delay between the data exchanged at the co-simulation step. The pure linear convergence property of the iterative method allows it to be accelerated towards the true solution by a non-intrusive Aitken's acceleration of the convergence post-processing, even if the domain decomposition interface conditions make the iterative method divergent. This provides a method less sensitive to the splitting. Numerical tests on a linear RLC circuit combining EMT and TS modeling are provided.
