This paper proposes a new adaptive control technique for shunt active power filter (SAPF) by applying the interval type-2 fuzzy controller (IT2FC) in the DC voltage outer loop. This adaptive method achieved the main control objectives and compensated the active filter parameters uncertainties besides the unbalanced loads compensation without neutral wire. The interval type-2 fuzzy controller (I...

The typical loads in the commercial buildings comprise of many single phase and three phase loads which includes non-linear loads. These loads are highly sensitive for any input variations in voltage. The performance of the electrical equipment gets worsened if they are supplied with polluted or distorted voltage. This paper presents modeling and analysis of custom power devices. SAPF based UPQ...

The main objective of this study is to mitigate current harmonic issues in hybrid renewable energy systems based on solar photovoltaic (SPV) and wind distribution.

Power quality problem is t he most sensitive problem in the power system. The objective of the project is to reduce one of the power quality issue called “harmonics” using compensation technique. Shunt Active Power Filter (SAPF) is used to eliminate harmonic current and also it compensates reactive power. In this project, both PI controller and Fuzzy Logic Controller based three-phase shunt act...

The three-phase three-wire neutral-point-clamped shunt active power filter (NPC-SAPF), which most adopts classical closed-loop feedback control methods such as proportional-integral (PI), proportional-resonant (PR) and repetitive control, can only output 1st–25th harmonic currents with 10–20 kHz switching frequency. The reason for this is that the controller design must make a compromise betwee...

Introduction The excessive use of power electronic equipments, which represent nonlinear loads, in a distribution network has caused many disturbances in the quality of power such as harmonic pollutions, unbalanced load currents, and reactive power problems. As a result poor power factor, weakening efficiency, overheating of motors and transformers, malfunction of sensitive devices etc. are enc...

— Non-linear electrical loads connected to power systems introduce non-active power components. The current harmonics and reactive power deteriorate the power quality and reduce the electrical system efficiency. These non-desirable effects can be avoided by using shunt active power filtering. This is a relevant topic in electrical and power electronics systems and, as a consequence, it must be ...

A new controller based on a fractional-order synergetic (FOSC) is proposed for three-level T-type inverter using shunt active power filter (SAPF). The SAPF designed to compensate the reactive and eliminate current harmonics caused by non-linear loads, in cases of distorted or unbalanced source voltages. FOSC technique with parameters defined macro-variable robust control that operates well both...
