In this project presents a Design of a Unified Power Quality conditioner (UPQC) connected to three phase four wire system (3P4W). The unbiased of sequence transformer used in the 4th wire for the 3P4W system The unbiased of sequence transformer used in the 4th wire for the 3P4W system. The neutral current which will flow toward electrical device neutral purpose is remunerated by employing a four-leg voltage supply electrical converter topology for shunt half. The series electrical device neutral are at virtual zero potential throughout all in operation conditions. In this simulation we tend to observe the facility quality issues like unbalanced voltage and current, harmonics by connecting non linear load to 3P4W system with Unified Power Quality conditioner. A new management strategy like unit vector model is employed to style the series APF to balance the unbalanced current gift within the load currents by increasing the concept of single phase P-Q theory.
