摘　　要：分布式潮流计算对大规模电网的潮流跟踪具有重要意义。目前分布式潮流计算的研究主要集中于异步迭代方法或krylov子空间法。根据快速解耦法潮流计算雅克比矩阵不变的特点,提出了一种新的潮流并行计算方法。建立了任务分配机制对雅克比矩阵进行分配,利用Socket技术和高斯消元的技巧完成并行化求逆。最后通过算例验证了该方法在减少计算、存储开销方面的优点。Distributed power flow calculation is important for power flow tracing. At present, the research of distributed power flow calculation is mainly focused on asynchronous iteration or krylov methods. Present a new parallel computing method for power flow based on the characteristics of Jacobi matrix. By creating a task allocation mechanism to allocate Jacobi matrix, using socket technology and gauss elimination, the parallel computing method is completed. Finally, the results shows that the present has benefit on reduce the computation cost and storage.
