چکیده
Unified power quality conditioners (UPQCs) allow the mitigation of voltage and current disturbances that could affect sensitive electrical loads while compensating the load reactive power. This paper deals with unified power quality conditioner (UPQC), which aims at the integration of Series-active and shunt-active power filters. The main purpose of a UPQC is to compensate for voltage Imbalance, reactive power, negative-sequence current and harmonics. In this paper, unified power Quality conditioner (UPQC) is designed and simulated by synchronous reference frame theory. The Proposed system is comprised of series and shunt inverters which can compensate the sag, swell and Unbalance .Voltage harmonics and also the reactive power. PI controller is used to stabilize DC link Voltage and balance the active power between the shunt and series inverters. The capacity of series And shunt inverters is calculated through loading calculations of these inverters applying phasor diagram to increase the design accuracy. The results of simulation in MATLAB/SIMULINK software Show that the system operates correctly.
