“…To improve the quality of power supply three phase three wire (3P3W) DSTATCOM has been proposed. There are various topologies reported in the literature for three-phase four-wire system [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21] such as a three single voltage source converter, split capacitor voltage source converter and four leg voltage source converter. The limitations of these control techniques are increase in KV A rating of the inverter and unequal voltages across the capacitor.…”

“…It is imperative for an optimized compensator to regulate DC bus capacitor voltage close to the reference value as far as possible. The capacitor voltage of DSTATCOM takes few cycles (normally [6][7][8] to settle under the disturbances in the loads [26]. The fuzzy logic and adaptive neuro fuzzy logic controllers may be used for improving the dynamics of traditional PI controller to have improved regulation on the DC bus voltage of DST ATCOM, eliminating higher overshoot and undershoot [28][29][30][31][32].…”

This paper presents the modelling and implementation of a three-phase DST ATCOM (Distribution Static Compensator) using an efficient control algorithm for power conditioning. This is one of an effective way for harmonic suppression, load balancing and reactive power compensation at distorted PCC (Point of Common Coupling) voltages under nonlinear loads. It is hoped at providing a broad perspective on the status of DSTATCOM control methods to researchers and application engineers dealing with harmonic cancellation issues. The proposed scheme consists of a zigzag transformer, double tuned filter, rectifiers, voltage source converter of the DST ATCOM. A fuzzy logic controller & traditional PI controller are used to control the neutral current & dc link voltage under both balanced & unbalanced loading conditions. Simulation studies are showing the better performance of three-phase DSTATCOM using MAT LAB SIMULINK & power system toolboxes.

“…These harmonic currents cause excessive heating in distribution transformer, overheating of conductors, electrical noise and unnecessary tripping of circuit breakers in the system. Some of the remedial measures to minimize these harmonic currents include use of active and passive filters, use of zigzag transformer and use of separate neutrals for non-linear loads [2]- [3]. All these remedial measures lead to the increase in overall investment cost.…”

Induction generators are most suitable for renewable energy conversion systems such as micro/pico hydro & wind power generation systems due to their advantages over conventional synchronous generators. These induction generators are of small ratings when used for pico-hydro power plants in remote mountainous locations and mostly feed the single-phase domestic load using 3-phase 4-wire system. However, the growing use of non-linear electronic loads in domestic applications such as CFLs, LEDs, computers etc., various harmonics are generated which adversely affects the power quality at the AC supply mains. This paper presents a solution for harmonic mitigation in a 3-φ self-excited induction generator (SEIG) based pico-hydro power plant operated in isolated mode, using star-delta and zigzag transformers feeding non-linear load. The complete system is modeled and its performance is simulated in MATLAB/Simulink environment. The performance simulation results are presented to demonstrate the effectiveness of star-delta and zigzag transformers in power quality control.

“…Problems like harmonics, inter-harmonics, flicker, notches, sags, swells can cause malfunction of equipment's based in microelectronic circuits that are very sensible to disturbances in the power supply [1]. Harmonic currents on the power system can distort the line voltage and lead to several adverse effects including equipment overheating, the malfunction of solid-state equipment and interference with communication systems [2].…”

This paper presents a Shunt Active Power Filter (SAPF) topology using four bi-directional power switches. The SAPF provides a current pathway for the distorted current when supply voltage is connected to a nonlinear load. Hysteresis current control loop switching strategy is used to re-shape the distorted current. Therefore, total input current drawn from the supply will be in sinusoidal shape & in the phase. Safe commutation strategies is developed to prevent over current spike during the transition between positive cycle and negative cycle of the remaining distorted current. MATLAB/SIMULINK is used to simulate and verify the operation of the SAPF. Laboratory prototype for this topology is built & tested. This will provide the clean power at source side in terms of Power Factor and Total Harmonics Distortion (T.H.D.).
