摘　　要：将矩阵求边运算的松弛方法应用于电力系统潮流计算，提出了一种新的电力系统潮流的并行松弛牛顿计算方法。该并行算法既适合于向量机，亦适合于非向量、多处理器并行结构。利用并行虚拟机技术在计算机网络上对所提出的并行算法进行了实际装配。研究结果表明，所提出的并行算法具有较好的收敛性和并行程度，可以获得较高的加速比和并行效率。In this paper. a new algorithm for parallel power flow calculation is proposed. The algorithm adopts relaxation method of matrix inversion to avoid (direct or indirect ) inverse of Jacobian matrix in conventional power flow calculation. thus it presents a large degree of parallelism in space. The algorithm is compared with classical Newton Power flow calculation method in convergence rate and solution time. Furthermore. the proposed algorithm is implemented and tested in a computer network composed of 11 HP workstations by the use of parallel virtual machine (PVM) system. The results show that the algorithm is of better convergence and parallelism.
