摘要
描述了一种大规模联合电力系统短路电流计算的并行处理技术。应用分块技术将大系统分割为若干子系统，求出节点阻抗矩阵中相关的列。此过程可用多处理机并行运算，或由多台单处理机并行运算。给出的计算实例说明其有令人满意的精度，且有很好的运算速度。
It describes a parallel analysis technique of short circuit current calculation for large scale united power syStem. The large system is divided into several subsystems by using diakoptical technique, and related rows of nodal point impedance matrices are solved. The process can be calculated parallelly either by a multicomputer or by several single-processor computers. The given example shows that the accuracy is very satisfactory and it has higher speed of calculation.
