A P2P-Based Hybrid Parallel Algorithm for Online-Checking Protection Setting

考虑到大型互联电网规模的逐渐扩大,尤其是"三华"特高压同步电网的顺利投运,传统的集中式计算会遇到硬件计算能力的瓶颈,提出了一种基于P2P的保护定值在线校核混合并行算法。充分利用P2P网络技术的对等通信,实现区域间信息的对等交互,重点介绍了MPI+OpenMP的混合并行编程模型以及算法的设计,对在线校核进行了并行性分析,实现了在线校核进程级与线程级的两级并行。最后,在基于P2P技术的分布式并行计算平台上,对混合并行算法进行了测试比较,结果表明所提出的算法正确且有效。

Taking into account the gradually expanded scale of large interconnected power system,especially the UHV synchronous grid successfully puts into operation. Traditional centralized computing will encounter the bottleneck of hardware computing power. A protection setting online checking hybrid parallel algorithm based on P2P is proposed. Peer-to-peer communications using P2P network technology to achieve inter-regional information fast interactive. The design of MPI ＋ OpenMP hybrid parallel programming models and algorithms is emphatically introduced. Online checking two levels parallel of process-level and thread-level is achieved through the parallel analysis of online checking. Finally,the hybrid parallel algorithm was tested and compared based on P2P technology distributed parallel computing platform. The results show that the proposed algorithm is correct and effective.
