基于MPI的电网仿真实时并行计算平台

Real-time Parallel Computing Platform of Power Grid Simulation Based on MPI

在电力系统动态电磁暂态仿真的并行计算中,存在超实时和硬实时的问题。为此,提出一种基于MPI的实时并行计算平台。引入硬实时操作系统RTLinux,采用实时内核和PSDD编程模式对仿真并行计算程序、MPICH并行环境和GM软件等进行重构,以获得硬实时特性。测试结果证明,该平台的平均时间性能提高约10%,时间的最大抖动幅度降低50%～80%,并减少了时间的抖动频率。

Aiming at electricity system dynamic electromagnetism transient state parallel computing pass real-time and hard real-time problem,this paper proposes a real-time parallel computing platform which is based on MPI.By introducing hard real-time operating system,RTLinux,and using real-time core,PSDD programming model to reconstruct the simulation parallel computing program,MPICH parallel circumstance and GM software,it can have hard real-time character.Test results show that,the average time performance enhances about 10%,and maximum jitter range reduces 50%~80%.It can also reduce time jitter frequency.
