“…When the system is effecting unbalance of power quality issues, in order to overcome to design of UPQC with new control technique for the improvement of power quality using FLC alone, along with PI controller and its comparison is reported in [2]. When the system is connected to 3P4W, the improvement of power quality issues like a voltage, current unbalance, distortions, reactive power demanded by the load using UPQC is reported in [5] - [10].…”

Abstract-A new control structure for two feeders, three phase four wire distribution systems (3P4W) operating with multiconverter unified power quality conditioner (MC-UPQC) is proposed in this paper. The modified synchronous reference frame theory (MSRF) is mainly used in the new controller design. The proposed system is designed and applied for two feeders of 3P4W with UPQC. This system associated with three voltage source converter which is connected commonly to two feeder distribution systems. Under linear and nonlinear load conditions, the proposed control scheme is simulated with 3P4W and it is efficiently compensate the voltage sag and reduce the total harmonics distortion. The fast dynamics response of dc link capac itor is achieved with the help of FLC controller (Fuzzy logic controller). The neutral current flowing in series transformers of the two feeders is zero with the implementation of proposed system.

“…Since then, a new language was developed to describe the fuzzy properties of reality, which are very difficult and sometime even impossible to be described using conventional methods. Fuzzy set theory has been widely used in the control area with some application to power system [5]. A simple fuzzy logic control is built up by a group of rules based on the human knowledge of system behavior.…”

“…These resultant two phase systems can be represented in α-β coordinates, and thus P-Q theory applied for balanced three phase system [11] can also be used for each phase of unbalanced system independently. In order to eliminate these limitations, the reference load voltage signals extracted for series APF are used instead of actual load voltage [12], [13].…”

Abstract-In this paper presents a Design of a Unified Power Quality conditioner (UPQC) connected to three phase four wire system (3P4W). The neutral of series transformer used in the fourth wire for the 3P4W system. The neutral current that may flow toward transformer neutral point is compensated by using a four-leg voltage source inverter topology for shunt part. The series transformer neutral will be at virtual zero potential during all operating conditions. Here we observe the power quality problems such as unbalanced voltage and current, harmonics by connecting non linear load to 3P4W system with Unified Power Quality conditioner. A new control strategy is proposed to the control algorithm for series APF is based on unit vector template generation to compensate the current unbalance present in the load currents by expanding the concept of single phase P-Q theory. The P-Q theory applied for balanced three phase system. And also be used for each phase of unbalanced system independently. The MATLAB/Simulink based simulations are provided the functionality of the UPQC.Index Terms-Series active power filter, shunt active power filter three-phase four wire systems (3P4W), P-Q theory, harmonics, power quality, unified power quality conditioner (UPQC).
