POLYMORPHIC PHASE COMPONENTS METHOD AND ITS APPLICATION IN THREE-PHASE UNBALANCE CALCULATION OF POWER SYSTEM

JIANG Tong, GUO Zhi-zhong, CHEN Xue-yun, BAI Xue-feng (School of Electrical Engineering and Automatization, Harbin Institute of Technology, Harbin 150001, China)  
The three-phase unbalance problems in power system make it difficult to apply symmetrical components. Phase components method may offer advantages in the analysis of unbalanced three-phase networks. In despite of the attribution that symmetrical components in power system can be decoupled, phase components method has too large calculation to apply widely. Based on phase co-ordinate representation, the polymorphic phase components can be used to deal with all kinds of unbalance problem. The unification of three-phase and single-phase calculations is realized with polymorphic matrices and vectors calculation. Calculation is reduced by polymorphic matrix translation and is similar as symmetrical-component quantities.
