In the process of constructing Y-matrix and Z-matrix by traditional method of adding branches, the additional of mutual inductance line is more complex than non-mutual inductance line. A novel algorithm of constructing Y-matrix and Z-matrix based on branches group is put forward in this paper. The algorithm can unify the calculation method of mutual inductance branches and non-mutual inductance branches efficiently. The calculation amount of adding mutual inductance branches is reduced to as same as that of non-mutual inductance branches. Case studies show that the computing method based on the algorithm provided by this paper is simple and unified, reduces the amount of computation and improves the computational efficiency.
