并行仿真计算中的新交替迭代解法

NEW ALTERNATE ITERATION METHOD FOR PARALLEL SIMULATIONS OF ELECTRIC POWER SYSTEM DYNAMICS

本文针对电力系统并行仿真算法中的分块对角加边模型提出了一种新的交替迭代解法。电力系统分成几个子系统和一个协调系统。每个子系统由一台计算机计算，协调系统由一台或多台计算机完成。每个子系统引入两个新矩阵，协调系统引入一个。仿真实例计算结果表明，新方法具有很好的收敛性。

A new alternate iteration method based on block bordered diagonal model for parallel simulations of electric power system dynamics is presented in this paper.The whole power system is divided into some subsystems and one coordinatinn system. Each subsystem can be calculated by one computer ,and the coordinating system can be put on one or more computers.Two new matrices are introduced in each subsystem and one new matrix in coordinating system.The calculation results show that the new method has very good convergence.
