摘要

考虑到大型电力系统分析计算耗时过多，提出一种适用于电力系统分析计算的多核并行技术。以短路计算为例，详细给出了如何采用多核并行计算将节点矩阵分解后求解的基本流程。通过仿真分析验证了所述方法，对算法使用前后的效果进行了对比。在此基础上，针对华中电网的节点模型，进行了故障计算的测试，并比较了多核并行计算方法与基于集群计算方法的性能。结果表明所提出的多核并行计算方法正确且有效。

Abstract

Given that the analysis and computation of large scale power system are time-consuming， a multi-core parallel computation technique suitable for power system analysis is proposed. Taken the example of short-circuit fault analysis， a detailed procedure is provided on how to apply the multi-core parallel computation to decompose and solve the node based matrix. The method proposed is verified by the simulation tests and the comparative analysis on the results with or without using this method. Furthermore， a test on the fault computation on the Central China power grid is conducted and the performance of multi-core parallel computation and of clustering computation is compared. The results show that the method proposed is correct and effective.
