摘要
在介绍和比较多波前算法(multifrontal algorithm,MA)和传统的稀疏三角分解技术的基础上,把MA应用于IEEE118节点系统、IEEE300节点系统的潮流计算以及IEEE145节点系统的暂态稳定性分析计算,得出结论:应用MA的潮流计算和暂态稳定性的分析计算比采用传统的稀疏三角分解技术计算要快,加速比明显,而且应用的规模大,此外,鉴于MA具有的并行特性,它是解决现代大规模电力系统实时计算及控制的有效途径,适合于可重构系统的计算。
The multifrontal algorithm（MA）and conventional direct sparse factorization method are described and compared.Upon applying MA to load flow calculation of IEEE 118 and IEEE 300 node systems as well as the transient stability analysis and computation of IEEE 145 node system,it is concluded that the load flow calculation and transient stability analysis using MA has higher efficiency,more obvious speed-up ratio and larger application scope than conventional direct sparse factorization technique.Furthermore, due to its parallelism, MA is an effective solution to real-time calculation and control of modern large power system and applicable to the computation of reconfigurable system.
