Abstract
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.
