| 摘 要： | 提出了一种易于并行化的重叠分块牛顿法，用它可对潮流方程进行快速求解。算法的关键是将雅可比矩阵划分为一系列带部分重叠的对角块，在几种图论方法的基础上给出具体划分的方法。用IEEE 118节点的电力系统对算法进行了串行实现，并与分块简化牛顿法和牛顿法进行了比较。

| Abstract: | In this paper a overlapped block Newton method prone to paralleled computer is presented for solving load flow equations faster.The key to the method is to partition the Jacobian matrix into a series of partially overlapped blocks.Several overlapped partitioning strategies based on graph partitioning algorithms are discussed also.Then,a serial implementation of the new method is performed on the IEEE118-bus system and the numerical results are compared with those from both the block simplified Newton method and Newton method. |
