电力变压器

The proposed method can work well under asymmetry element parmeters, and it is not necessary to consider the phase shift of ideal transformer or using multi-port net theory, which make the proposed method more applicable and simplify the calculation program. The method is also capable of handling various unsymmetrical calcuations, such as the fault calcuation for power system without complete transposition.
