The three phase unbalanced unbalance in the electrical power system makes it difficult to apply the symmetrical components. Phase component is one of the methods to study the three phase unbalance in the electrical power system. The polymorphic phase components based on phase co ordination representation can be used to deal with all kinds of unbalances and the unification of three phase and single phase calculations is realized with polymorphic matrix calculation which makes its application possible in the electrical power system.
