Power Quality Improvement Using Fuzzy Controlled Shunt Active Filter
This paper proposes a new control method of three phase active power filterfor reducing the source current harmonics for nonlinear loads. The control strategy includes the dq transformations and hysteresis technique for current injection. Renewable energy source (solar energy) is used as a backup device for converter. Dc voltage deviations due to harmonic injections are tracked by using proport...
متن کاملShunt Active Filter for Power Quality Improvement
This paper describes the development of a low cost shunt active power filter with digital control, which allows dynamic power factor correction and both harmonics and zero-sequence current compensation. The active filter controller is based on the instantaneous power theory (p-q theory) and was implemented using a standard 16 bits microcontroller. The p-q theory is introduced followed by the pr...
متن کاملFuzzy Logic Controlled Shunt Active Power Filter for Power Quality Improvement
This paper presents a novel control strategy for achieving maximum benefits from these grid-interfacing inverters when installed in 3-phase 4-wire distribution systems. The inverter is controlled to perform as a multifunction device by incorporating active power filter functionality. The inverter can thus be utilized as: 1) power converter to inject power generated from RES to the grid, and 2) ...

15 صفحه اولAdaptive Hysteresis Band Based Fuzzy Controlled Shunt Active Power Filter
Conventional hysteresis current controllers have the disadvantage of a variable switching frequency. This paper proposes a fuzzy hysteresis band technique for the current control for shunt active power filter (SAPF). An active harmonic filter is used to eliminate current harmonics caused by nonlinear loads. The current control strategy utilizes using a selective Filter STF method to improve pow...
