Abstract
A set of power element models are established in an /spl alpha/-/spl beta/-0 reference frame with different degrees of coupling. For untransposed, asymmetrical three-phase transmission lines, the so-called decoupling compensation models can be used. For Y/delta-connected transformers and fault/manipulation interfaces, different sets of low-order algebraic equations are introduced. Thus, by incorporating these models with certain appropriate techniques of bus-ordering, an asymmetrical three-phase power system can be simulated by three loosely interconnected /spl alpha/-, /spl beta/- and 0-phase models. Simulation practice verifies the validity and effectiveness of this approach.
