| 摘要: |
| 暂态稳定分析的并行求解研究主要集中在对暂态计算时数学方程的并行化、暂态计算的内在并行性2方面。从网络分割的角度出发,采用基于支路分割的并行算法,以分割支路两端的电压为交接变量,将分割支路两端的节点看作有注入电流的节点,通过迭代最终实现并行计算。以MPICH.NT.1.2.5作为操作平台,利用MPI(MessagePassingInterface)传递函数库实现并行通信。最后,通过IEEE39节点系统对该算法进行测试,验证了该算法的正确性,并且通过与传统算法的比较得到了令人满意的并行加速比。 |

| Abstract: |
| Current parallel solution of transient stability analysis mainly focuses on two directions:the parallelism of mathematical equations for transient calculation and the inner parallelism of transient calculation.A kind of parallel algorithm based on branch cutting is adopted from the point of web cutting.It regards the voltages at both ends of a cut branch as conjoining variables and the nodes as nodes with injection currents,then uses iteration to realize parallel calculation.MPICH.NT.1.2.5 is used as operating platform and the MPI transfer function database to realize parallel communication.It is used in IEEE 39-bus system and the result proves its correctness and the satisfying parallel accelerator is achieved through comparison with traditional algorithms. |
