Abstract
DSTATCOM (Distribution STATic COMpensator) isused for compensation of reactive power and unbalance caused by II. SYSTEM CONFIGURATIONvarious loads in distribution system. This paper evaluates three Fig. 1 shows the basic circuit diagram of the DSTATCOMdifferent methods of determining the compensating current for a system with lagging power factor loads connected to 3-phase,DSTATCOM. The methods compared, are the instantaneous 3-wire distribution system. The lagging power-factor load isreactive power theory, synchronous referen ....etc

Microgrid Power Quality Enhancement Using a Three-Phase Four-Wire Grid-Interfacing Compensator


INTRODUCTION

MICROGRIDS can generally be viewed as a cluster of
microgenerators connected to the mains utility grid,
usually through some voltage-source-inverter (VSI)-based interfaces.
Concerning the interfacing of a microgrid to the utility
system, an important area of study is to investigate the impact
of unbalanced utility grid voltages and utility voltag ....etc

POWER QUALITY ENHANCEMENT BY COMPENSATING CUSTOM POWER DEVICES
INTRODUCTION
 The term power quality refers to maintaining a sinusoidal waveform of bus voltage at rated voltage and frequency.
 Over the last 20 years the number of PQ problems are experienced in industrial and commercial sites are increased dramatically.
 The waveform of electric power at generation stage is purely sinusoidal and free from any distortions. There are many devices the distort the waveform tha ....etc

Hi,
I'm doing a project on Power quality improvement in transmission line using D-statcom.

This paper presents the enhancement of voltage sags,
harmonic distortion and low power factor using Distribution
Static Compensator (D-STATCOM) with LCL Passive Filter in
distribution system. The model is based on the Voltage Source
Converter (VSC) principle. The D-STATCOM injects a current
into the system to mitigate the voltage sags.LCL Passive Filter
was then added to D-STATCOM to improve harmonic distortion
and low power factor.
