Abstract
In this paper, A Distribution Static Synchronous Compensator (D-STATCOM) is used for improving the power factor, power quality and to control power flow control in the distribution line. It used to give reactive and active power compensation in the distribution line. The power depends on the power factor of the loads connected to the transmission line. In this paper we have used a new DSTATCOM using modified SVPWM technique. The previous DSTATCOM are basically controlled by PWM, or SPWM technique which produce high harmonics distortion but using SVPWM technique distortion reduces to maximum possible level. In our system we also have examined the losses due to DSTATCOM when connected in the distribution system. To decrease the reactive power and to minimize the undesirable load to require maintains the flow of reactive power. As a result, the power a factor of the load descant, leading to the limitation of the active power flow in the line. The D-STATCOM is a power electronics based on advanced device can be used to control power flow in the distribution line. The construction of system is able to recover the drop-in bus voltage when any loading effect arises, but due to 5th harmonic performance of DSTATCOM reduces somewhere.
Highlights
Days, the whole world economy emphasizes on providing qualitative and uninterrupted services in every sector
D-STATCOM which works on low voltage and compensate of reactive power, injects the reactive power in the line
D-STATCOM operates as Voltage Source Converter (VSC) which employment at the load side of the system can be which improve the voltage profile of system and reduce the power losses
Summary
The whole world economy emphasizes on providing qualitative and uninterrupted services in every sector. The Electrical Power Distribution system Nonlinear equipment’s like light emitting diode lamps, switching mode power supplies, equipment’s which use the electronic controllers and switching devices are very sensitive to poor voltage quality. They cannot provide continuous service and can be damaged due to the poor voltage quality is used to provide active and reactive power in the connected loads through the distribution line using the distribution transformer. In this paper D-STATCOM is used to provide direct control scheme to generate the gate pulses for switching devices of Voltage Source Converter (VSC) by active and reactive power control and removed the reference current. D-STATCOM can be connected at coupling point of low voltage feeders to provide voltage controllability
