SSSC to control Power flow in the Line

FACTS controller is the Power Electronics based static controller which enhance power transfer capability and increase controllability of the power system network. Static Synchronous Series Compensator (SSSC) is VSC based controller which is used in transmission network with the aim of utilization of existing line upto its fullest extent. This paper demonstrates transmission line power flow control with the help of SSSC. A control scheme of SSSC is presented to control active power flow in the line. Increase in the power flow in the line is realized with SSSC operation in capacitive mode of operation and decrease in the power flow is realized with SSSC operated in inductive mode of operation. MATLAB simulation studies are demonstrated to validate the SSSC operation.

Distribution Line

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.

Power Flow Controller

Unified Power Flow Controller (UPFC) is the most prominent versatile FACTS controller applied in power system providing dynamic control of transmission line parameters. It can achieve Voltage regulation, series compensation and phase shifting independently. It provides combined advantages of STATCOM and SSSC by connecting two VSC’s with common dc coupling. Active power and reactive power can be directly controlled using UPFC. This paper presents UPFC for active power flow control through transmission lines. Control scheme based on d-q transformation is demonstrated. System studies are presented in MATLAB Simulink to present the active power flow control in the line.
