Abstract: This paper investigates the impact of voltage imbalance on power distribution systems and equipment in various practical cases. The definition of voltage imbalance is introduced first, followed by description of the origins of voltage imbalance, and finally simulation results and discussion of the impact of voltage imbalance on systems and equipment for specific cases are presented. A commercial software package, Matlab/Simulink„¥ was utilized to build full-scale mathematical models of power distribution systems. The simulation results of the study cases have indicated clearly, the causes and impacts of voltage imbalance. The results are of value to engineers and experts in designing suitable power distribution systems, balancing single-phase loads in three phase systems and thereby improving system efficiency.
Keywords: voltage unbalance, power distribution system, system efficiency, neutral wire.
