Abstract：In this paper, the equivalent circuit diagram of UPQC is made by the working principle of UPQC and its functions. Then according to the function of UPQC, its power expression is deduced and analyzed when dealing with power quality problems in fundamental and harmonic condition. The instantaneous and average power flow of UPQC is obtained. The conclusions are helpful to grasp the detailed working situation and provide guidance for engineering commissioning, which is helpful to the accurate design of UPQC's main circuit capacity.
