电力系统计算中的二维稀疏结构技术

The 2-order sparse structure in power system calculations

提出了一种既能方便解决单相电力系统中的稀疏矩阵的存取 ,又能方便解决三相电力系统计算中的稀疏矩阵存取问题的二维稀疏结构技术。该技术还方便地解决了单、三相计算中迭代方程组系数方程的存取及非零元素注入问题。使得处理稀疏矩阵象处理二维数组一样地简单。把二维稀疏结构作为一种基本数据结构来描述 ,这对形成电力系统计算类库具有实际意义。

A universal sparse structure was presented in this paper.Sparse structure can easily solve the problem of sparse matrix in single phase calculations,it can also solve the problem of sparse matrix in three phase calculations. With this method,the injection of non zero element in coefficient matrix of linear equations can be solved easily.It also benefits of building a library of power system calculations.
