Increased use of nonlinear loads brought about many technical conveniences and economical profits, but on the other hand it has exerted a continual growing influence on the power system's operating conditions. Active power filter (APF) emerged as an effective solution to the power quality problems caused by nonlinear loads and unbalanced sources. Out of various hybrid Active power filter (APF) configurations, the series hybrid active power filter (SHAPF) has become more popular in recent time. The SHAPF is capable of compensating both voltage harmonics generating load and current harmonics generating load. This research work includes the study and experimental validation of SHAPF with a novel control algorithm, to compensate source current harmonics and source voltage unbalances simultaneously. Simulation and experimental investigations is presented for evaluating the performance of different control algorithms of SHAPF. In the experimental prototype the control circuit is developed using ARM Cortex-M4 STM32F407VGT6 microcontroller. The experimental results confirm the effectiveness of the proposed control algorithm and also validate the simulation results.

The proposed shunt active filter compensate for balance and unbalanced nonlinear load currents, adapt itself to compensate variations in nonlinear load currents, and correct power factor of the supply side near to unity. Proposed Active Power Filter (APF) topology limits %THD of source current under limits of IEEE-519 standard, and also have been observed that reactive power compensation has improved leading to power factor improvement. After checking the performance of the system for various load conditions with the above said list of control strategies, the hybrid filter / control technique is observed as more adoptable for the system in order to ensure the improved power quality. The validity of the presented controllers was proved by simulation of a three phase four wire test system under balanced, unbalanced and variable loading conditions. Finally all the control strategies are compared and the results are found to be quite satisfactory to mitigate harmonic Distortions, reactive power compensation and power factor correction.

Modelling and Simulation of SRF Based 3 Phase 3...

The presence of harmonics in power lines results in greater power losses in the distribution system, interference problems in communication systems and, sometimes, in operation failures of electronic equipments. Active filters are special equipments that use power electronic converters to compensate for current and/or voltage harmonics originated by non-linear loads, or to avoid that harmonic voltages might be applied to sensitive loads. In this book, Synchronous Reference Frame (SRF) theory is implemented for the generation of reference current signals for the controller. This book also illustrates how the functional definition of a switching converter can be used to model active filters. This book presents the comparative performance evaluation of the fixed hysteresis band current controller and the adaptive hysteresis band current controller for a three phase three wire shunt active power filter and inspects the effectiveness of the filter in harmonics currents suppression for both cases.

Power Quality Issues: Current Harmonics provides solutions for the mitigation of power quality problems related to harmonics. Focusing on active power filters (APFs) due to their excellent harmonic and reactive power compensation in two-wire (single phase), three-wire (three-phase without neutral), and four-wire (three-phase with neutral) AC power networks with nonlinear loads, the text: Introduces the APF technology, describing various APF configurations and offering guidelines for the selection of APFs for specific application considerations Compares shunt active filter (SHAF) control strategies for extracting three-phase reference currents, evaluating their performance under a number of source voltage conditions using a proportional-integral (PI) controller Presents PI controller-based SHAF instantaneous active and reactive power (p-q) and instantaneous active and reactive current (Id-Iq) control strategies, supplying detailed MATLAB®/Simulink simulation results Proposes SHAF control strategies using type 1 and type 2 fuzzy logic controllers (FLCs) with different fuzzy membership functions (MFs), analyzing their harmonic mitigation and DC link voltage regulation Verifies the proposed type 2 FLC-based SHAF control strategies with trapezoidal, triangular, and Gaussian fuzzy MFs using RT-LAB, a real-time digital simulation software from OPAL-RT Technologies Power Quality Issues: Current Harmonics is a useful resource for those tackling electrical power quality challenges. The compensation techniques described in this book alleviate harmonic issues that can distort voltage waveforms, fry a building's wiring, trigger nuisance tripping, overheat transformer units, and cause random end-user equipment failure.
