Phase voltage and current unbalance is a basic power quality concern. Three-phase power flow analysis is needed to investigate unbalance problems. In this paper, the unique modelling issues associated with unbalanced power flow calculations are discussed. Four types of load models are proposed. Using the concept of component level power flow constraints, a generalized method for three-phase power flow analysis is developed. Case studies supported by field measurement results are used to verify the proposed method and to demonstrate the deficiencies of traditional methods
