Abstract：In the process of building node-admittance matrix and node-impedance matrix by traditional adding branches method,the addition of mutual inductance line is more complex than non-mutual inductance line.A novel algorithm of building node-admittance matrix and node-impedance matrix based on branch groups is proposed in this paper.The method makes mutual coupling branches into a group.We can add the entire branches as a group into the network according to the derived adding equations.The algorithm has the characteristic of simple and unified computing method,reducing the amount of computation and improving the computational efficiency.The Practicality and Effectiveness of this proposed method is proved by calculation and comparison.
