This paper presents an overview of different control methods which are applied on Shunt Active Power Filter to achieve harmonics reduction and power factor improvement. In recent decades, the world has seen an expansion in the use of non-linear loads. These loads draw a non-sinusoidal current from the source and distribute them throughout the system. As a result the power quality degrades. Ther...

a significant problem in multicarrier communication systems is the necessity to reduce the value of papr (peak-to-average power ratio) of transmitting signal. in this thesis we study the effect of the system parameters such as coding and modulation types on papr and ultimate ber in a mc-cdma system. in this study we consider fading channel as well as the nonlinearity of transmitter’s amplifier ...

The selection of control strategy depends on the converters of the drive including power, speed, performance and the possible system costs. A number of attempts were therefore made in recent times to develop novel power electronic converter structures for SRM drives, based on the utilization. Many of the converters with variable speed drives have no input power factor correction circuits. This ...

This paper proposed the reduced rating star connected transformer based interline unified power quality conditioner. This work comprises of unified power quality conditioner connected between the two feeders, star connected transformer and LC filter. This hybrid approach significantly improves the performance of UPQC under unbalance source voltage condition. The UPQC adopted to compensate curre...

Distribution Static Compensator (DSTATCOM) is a custom Power gadget utilized for power quality change within dissemination framework. The control procedures connected to the DSTATCOM assume a real part in its execution. Throughout the previous three decades, a substantial scale mix of circulated era (DG) is starting to change the electrical circulation system from detached to dynamic. Thus, spe...

We proposed voltage-sourced converter (VSC) with Pulse-width modulation (PWM) provides a faster control that is required for flicker mitigation purpose. The voltage regulation in the distribution feeder is improved by installing a shunt compensator. The proposed DSTATCOM is modeled and its performance is simulated and verified for power factor correction and voltage regulation along with neutra...

Abstract: The paper intends to develop the artificial neural network control algorithm for the control of DSTATCOM for the improvement of power quality. The presence of nonlinear loads makes the voltage to be deviated and current to be distorted from its sinusoidal waveform quality. Thus harmonics elimination, load balancing and voltage regulation is the heavy task that has to be accomplished t...
